Episode 1: Character Introductions

Yang Hao: The male protagonist, a commoner student at the aristocratic Raymond Star Academy with abysmal grades. His life takes a wild turn after swallowing an immortal, launching him onto the path of the Dual Cultivation Cauldron Sect.
Hun Yuanzi: A legendary cultivator from thousands of years ago (circa 1800 AD), the last leader of the Dual Cultivation Cauldron Sect. Betrayed and reduced to a primordial spirit residing in a clay pellet, he now lives in Yang Hao’s dantian, determined to train him into a peerless immortal master.
Aisi: The academy’s beauty queen, half-Angel Star descent, making her breathtakingly gorgeous. Daughter of the Galactic Empire’s ambassador to Raymond Star, her privileged upbringing fuels her spoiled and willful personality.
Amanda: A long-legged beauty with a curvaceous figure, though her lack of fashion sense keeps her from being a standout. Hailing from a top-tier mechanical engineering family, she can build virtually any machine.

Galactic Empire: National Powers

Galactic Empire: Established in 2500 AD, Earth formed a unified government and began expanding to other planets.

Colonial Planets: Due to the empire’s vast size and limited Earth-born population, it rules fringe systems through colonization. Raymond Star, a typical colonial planet, hosts an imperial garrison and ambassador but allows local royal rule. One key colonial planet per star system can influence the entire region.

Tech Soldiers: Including fleets, infantry with advanced firearms, armored ground units, and long-range attack forces.
Combat Corps: Comprising the elite Swordsman Corps and Martial Corps. Swordsmen, capable of facing thousands of regular soldiers, hold higher status.

**Immortal Cultivation Theories – Paths to Immortality**
Immortal cultivation transforms ordinary humans into transcendent beings. Daoist teachings emphasize refining both body and spirit, aligning with the principle of “harmonizing form and spirit with the Dao.” Over generations, methods have varied, but key approaches include:

1. **Elixir Consumption:** Seeking immortality through divine herbs or alchemical concoctions, often involving toxic metals. Though once prominent, its dangers led to decline by the Song Dynasty.

2. **Qi Refinement & Breath Control:** Techniques like meditation, energy circulation, and embryonic breathing, integrated into broader cultivation practices.

3. **Internal Alchemy (Neidan):** Redirecting focus inward to refine vital essences (Jing, Qi, Shen) after external alchemy’s pitfalls. Rooted in texts like *Zhouyi Cantongqi*, it became mainstream post-Tang Dynasty.

5. **Worldly Deeds & Posthumous Deification:** Achieving immortality through heroic acts or posthumous recognition, as seen in figures like Guan Yu or Yue Fei.

**Immortal Cultivation Theories – Paths to Immortality**
Cultivation transforms ordinary humans into transcendent beings. Daoist philosophy emphasizes refining both body and spirit, leading to myriad methods over the ages. Key approaches include:

1. **Elixir Consumption:** Seeking immortality pills in celestial realms or crafting them via alchemy. Early alchemists used metals like gold and mercury, but toxicity led to decline post-Tang Dynasty. Alchemy also birthed metallurgy, though synthetic gold only mimicked the real thing.

2. **Qi Refinement and Breath Control:** Techniques like meditation, inner focus, and embryonic breathing to harness life energy. These methods, later popularized as health exercises, were initially sacred practices.

3. **Internal Alchemy (Neidan):** Redirecting focus inward to cultivate vital essences (Jing, Qi, Shen) after external elixirs proved dangerous. Modeled after external alchemy but using the body as the crucible, it became dominant post-Song Dynasty.

4. **Ritual Merit:** Performing ceremonies (e.g., requiems) to accumulate virtue, believed to hasten enlightenment. Practitioners like Zheng Suonan linked compassionate service to spiritual ascent.

5. **Worldly Achievements:** Heroes who served humanity and retired, like Guan Yu or Yue Fei, were deified posthumously.

True cultivation blends these methods with moral integrity—purifying the heart, eliminating selfishness, and doing good. Without virtue, even the most potent techniques falter. Thus, Daoist immortality harmonizes “technique” (术) and “virtue” (德).

**Titan Fleet:** Once one of the most outstanding and massive fleets of the Galactic Empire, it was utterly annihilated in the Battle of the Outer Mongolia Left Spiral Arm, with nearly all officers and soldiers killed.

**Path to Immortality:**
Immortality cultivation transforms ordinary humans into transcendent beings. Daoist teachings emphasize refining both body and spirit, leading to countless methods over centuries. Key approaches include:

1. **Elixir Consumption:** Seeking eternal-life elixirs in celestial realms or crafting them (e.g., golden elixirs). Though once dominant, their toxicity led to decline post-Tang Dynasty. Alchemy also birthed faux gold/silver production (transmutation), a precursor to experimental chemistry.

Cultivation transforms ordinary humans into transcendent beings. Daoist teachings emphasize refining both body and spirit, leading to countless methods over the ages. Key approaches include:

1. **Elixirs:** Seeking immortality pills in celestial realms or crafting them (e.g., golden elixirs). Though once dominant, their toxicity led to decline post-Tang Dynasty. Alchemy also birthed faux gold/silver (yellow/white art), precursors to experimental chemistry.

2. **Qi Refinement & Breath Control:** Early immortal practices involved absorbing Qi (vital energy), evolving into techniques like external Qi absorption, meditation, and embryonic respiration. These later became mainstream health exercises.

3. **Internal Alchemy (Neidan):** Developed from Qi practices, focusing on refining internal essence (Jing, Qi, Shen) instead of external materials. It replaced external alchemy (Waidan) as the primary cultivation method by the Song Dynasty.

5. **Worldly Achievements & Divine Recognition:** Heroes who retreat after great deeds (e.g., Guan Yu, Yue Fei) may ascend posthumously as gods.

Cultivation transforms ordinary humans into transcendent beings. Daoist teachings emphasize refining both body and spirit, leading to countless methods over the ages. Key approaches include:

1. **Elixir Ingestion:** Seeking immortality pills in celestial realms or crafting them (e.g., golden elixirs). Though once dominant, their toxicity led to decline post-Tang Dynasty. Alchemy also birthed faux gold/silver (huangbai), precursors to experimental chemistry.

2. **Qi Refinement and Daoyin:** Breath control (e.g., external/internal Qi absorption, meditation) paired with physical exercises to channel energy.

3. **Internal Alchemy (Neidan):** Developed as external elixirs waned, focusing on inner resources (essence, Qi, spirit). Borrowing terms from alchemy but diverging in practice, it became mainstream post-Song Dynasty.

4. **Rituals and Merit:** Performing rites (e.g., fasting/offerings) to aid others and accumulate virtue, believed to hasten enlightenment.

5. **Worldly Achievements:** Heroes who retreat after great deeds may ascend posthumously (e.g., Guan Yu, Yue Fei).

**Note:** While methods vary, true cultivation combines technique with moral discipline—purifying the heart and doing good. Without virtue, even the mightiest arts fall short.

**Titan Fleet**: Once one of the most outstanding and massive fleets of the Galactic Empire, it was utterly defeated in the Battle of the Outer Mongolia Left Spiral Arm, with nearly all officers and soldiers killed. However, to save face, the Emperor later ordered robots to collect DNA fragments of the deceased across the cosmos, rebuilding the New Titan Fleet through cloning. Though it no longer matches its former glory, the New Titan Fleet remains one of the Empire’s most ruthless forces.

Theories of Immortality – Paths to Cultivation

Cultivation is the process of transforming an ordinary person into an extraordinary immortal. According to Taoism’s inherent view of physical form and spirit, cultivation necessarily involves equal attention to both body and spirit. Therefore, Taoist practitioners have long pursued the path of “wonderful form and spirit united, harmonized with the Dao.” However, different generations of Taoists have emphasized various cultivation paths, with countless specific methods attempted. The main approaches can be summarized as follows.

First is taking medicine, including obtaining the elixir of immortality in the fairylands and synthesizing medicine according to formulas. Originally, during the early Warring States period, those seeking the path to immortality mainly searched for the elixir of eternal life in places like the Three Sacred Mountains at sea. By the Western Han Dynasty, people began using artificial methods to synthesize medicine. The primary materials used were minerals, and the resulting products were often called Golden Elixirs or Golden Liquids. By the late Western Han and early Eastern Han dynasties, many alchemical texts were circulating in society, such as “The Divine Essence of the Supreme Golden Liquid” and “The Yellow Emperor’s Nine Cauldron Elixir Classic,” indicating that the theories and techniques of alchemy were already quite advanced. However, synthesizing elixirs required significant investment, and since many ingredients and products were toxic, alchemists conducted extensive experiments on themselves and others, discovering serious side effects. Thus, after reaching its peak in the Tang Dynasty, people began to recognize its drawbacks, and by the Northern Song Dynasty, fewer and fewer dared to consume elixirs, leading to the decline of this practice. Alongside alchemy developed the art of transmuting base metals like lead and iron into “precious metals” such as medicinal gold and silver, known as alchemy or chrysopoeia. However, the synthesized gold and silver were only similar in appearance and certain properties to real gold and silver, not genuine. Both Golden Elixirs and alchemy eventually declined, but they were pioneers in humanity’s quest to artificially control material changes and conduct experimental chemical research, occupying an important place in human civilization. This aspect is discussed in detail in the related section on “Taoism and Human Civilization” in this database. Before and during the Tang Dynasty, alchemy was the most significant part of cultivation techniques.

Second is breath cultivation and guiding techniques. As early as ancient times, immortality seekers regarded breath intake and cultivation as fundamental means of cultivation. Even when consuming Golden Elixirs, these were often combined with breath cultivation. In the Warring States period, the famous poet Qu Yuan mentioned breath intake techniques in his work “Far Journey.” Later, Taoism developed various techniques for breath intake, including absorbing and refining external energy, visualization, focusing on a single point, and embryonic breathing, among others. Although numerous, these breath intake methods were adopted in Taoism as primary or auxiliary means of cultivation. Later, these techniques spread to society, becoming physical practices accessible to the general populace.

Third is internal alchemy. Internal alchemy developed from breath cultivation. At the end of the Eastern Han Dynasty, Wei Boyang wrote “The Unity of the I Ching and the Golden Elixir,” combining external alchemy with internal cultivation, though his teachings had limited influence at the time. By the Sui and Tang dynasties, the drawbacks of consuming external elixirs became increasingly recognized, leading Taoist practitioners to focus on cultivating the inherent resources within the body—essence, energy, and spirit—to forge an immortal body. This method was called internal alchemy. The term “internal” was used in contrast to traditional external alchemy, which used external minerals as raw materials. Many theories and terms in internal alchemy were borrowed from traditional external alchemy, but their foundations were quite different, hence the distinction as “internal,” while the original external alchemy was termed “external.” Both methods often used terms like Golden Elixir, Great Elixir, or Golden Liquid for Rebirth. Whether a text discusses internal or external alchemy can be determined by examining the raw materials used in the described elixir-making process (often referred to as the Great Medicine in alchemical texts). From the Tang through the Song dynasties, internal alchemy gradually replaced external alchemy, becoming the mainstream cultivation technique.

**Titan Fleet:** Once one of the most outstanding and massive fleets of the Galactic Empire, it was utterly annihilated in the Battle of the Outer Meng Left Spiral Arm, with nearly all officers and soldiers killed. However, to salvage the Empire’s dignity, the Emperor later ordered robots to collect DNA fragments of the deceased across the cosmos, using cloning techniques to rebuild the New Titan Fleet. Though it no longer matches its former glory, the New Titan Fleet remains one of the Empire’s most ruthless forces.

**Thousand Saints King:** The greatest ruler in Saintarrian history, who led them to establish cosmic hegemony. After the “Day of Divine Retribution,” he vanished and is rumored to have perished.

**Maya:** Known as the “Light of the Saint,” she is a Saintarrian princess. Pursued by unknown forces during the “Day of Divine Retribution,” she fled to the Bear Star and was granted sanctuary by the Divine Bears, serving as their saintess to this day.

**Female Cauldron:** Materials required for the Alchemy Sect’s practices, using women’s bodies as alchemical vessels. Different bodies yield different effects.

**Celestial Hybrid:** A woman born from the union of an immortal and a mortal. These hybrids are exceptionally rare and possess unique effects when used as Female Cauldrons.

**Celestial King Fleet:** The military force of the Wang Clan, one of the Empire’s three great family armies, renowned for its formidable combat strength. Its King’s Blade Division ranks among the top ten in the Empire’s military power rankings.

**Spells:** Cultivators who reach a certain level can wield spells, though they consume vast amounts of spiritual energy, limiting their use.

**Luo Dongjie:** A rising star among the Privy Council’s generals, highly favored and betrothed to a high-ranking official of the Three-Crystal Sea System.

**Sunset Fleet:** One of the Empire’s main direct fleets, featuring uniquely powerful Titan-class ships. Stationed near the Bear Star system, it was deployed for the campaign against the Bear Star.

**Three-Crystal Sea System:** The Empire’s second technological hub, located at the border between the core and periphery. Comprising three silicon-rich planets, it has become a covert center for the Anti-Empire Alliance.

**Steve:** Governor of the Three-Crystal Sea System, a second-generation colonist who, for mysterious reasons, leans toward the Anti-Empire Alliance. A master strategist with profound political acumen, he is an enigmatic figure.

**Suffocating Black Hole:** One of the universe’s most terrifying black holes. Legend claims no one escapes its pull—even masters like Hunyuanzi require Divine Race intervention. Some say black holes are the Divine Race’s creations, with the Suffocating Black Hole serving as their hidden gateway.

**Xin Mei:** A Divine Race guide with modest divine power but astonishing beauty.

**Garuda:** A high-ranking Divine Race member capable of transforming into a golden-winged bird, once worshipped as a Buddha on Earth.

**Kadith Dragon Clan:** The most brutal and dark of the Divine Race, considered leaders of the dark faction. Divided into branches—Red, Green, Black, and Gold Dragons—based on power.

**Dragon Cliff:** The lair of the Dragon Clan. Due to Kadith Dragons’ dark energy, vast regions around it turn black.

**Dragon Breath:** The essence of draconic power, varying in color and form by attribute. Legends say any creature surviving three infusions gains their dark power.

**Dragon Breath Elixir:** Created by the Alchemy Sect’s founder to communicate with dragons, its immense cost deterred consumption.

**Great Light Technique:** The ultimate skill of the light faction’s leader, capable of annihilating dark-aligned beings. It once slew tens of thousands of Dark Angels in the Final Hall War.

**Related Materials – Cultivation & Alchemy**

**Path to Immortality:**
Cultivation transforms ordinary humans into transcendent beings. Daoist teachings emphasize refining both body and spirit, leading to countless methods over the ages. Key approaches include:

1. **Elixir Consumption:** Seeking immortality pills or crafting them, often using toxic metals. Though once dominant, its dangers led to decline.
2. **Qi Refinement & Breath Control:** Techniques like meditation, inner focus, and embryonic breathing to harness life energy.
3. **Internal Alchemy (Neidan):** Redirecting focus inward to cultivate vital essences (Jing, Qi, Shen), replacing external elixirs.
4. **Rituals & Merit Accumulation:** Performing ceremonies to aid others while accruing spiritual credit, advancing toward divinity.
5. **Worldly Achievements & Retreat:** Heroes who contribute greatly may ascend posthumously or retire to immortality.

True cultivation blends these methods with moral discipline, purifying the heart and performing good deeds to attain the Dao.

Fifth is achieving great accomplishments in the world while not forgetting one’s roots, retiring after success, and still attaining immortality, or being deified after death. Generally, those who entered the Taoist pantheon through official sacrifices in various dynasties, such as Guan Di, Dutiande (Zhang Xun), and Yue Yuanshuai (Yue Fei), are examples of those who attained divinity through merit.

It should be noted that although Taoism’s paths to immortality have the aforementioned distinctions, in actual cultivation practices, these methods are often combined and complement each other. Moreover, regardless of which cultivation secret one practices, practitioners must cultivate their minds, follow the Dao, accumulate virtue, constantly discipline their bodies and minds, purify their inner selves, eliminate all distracting thoughts, and perform good deeds in the world. Strictly speaking, the several basic cultivation methods mentioned above fall within the scope of “techniques,” while the moral requirements discussed here must be combined with these techniques to achieve the ultimate Dao.

Inventions from the Alchemical Cauldron
(The pursuit of immortality, chemical experiments in smoke and fire, and the accidental invention of gunpowder)

It is well known that gunpowder, papermaking, printing, and the compass are regarded as the Four Great Inventions of ancient China, later transmitted to Europe via the Arab world, playing a significant role in the development of human civilization. However, even today, many people may still be unaware that gunpowder originated in the alchemical furnaces of Chinese Taoist priests, and that its invention was closely related to Taoist alchemical practices. To fully understand this, we must first delve into the history of Taoist alchemy.

I. The Pursuit of Immortality through External Alchemy

Taoism is a religion that values life, cherishes existence, and emphasizes techniques. One of its core beliefs is the pursuit of eternal life. Although death is inevitable for humans, Taoism persistently seeks immortality. Is there a method to achieve eternal life? Taoism claims there is. The practice of refining external elixirs and consuming them was one of the primary methods adopted by Taoist practitioners.

Even before the formal establishment of Taoism, the concept of refining external elixirs had already emerged. During the Spring and Autumn and Warring States periods, people pursued longevity through various means. At that time, people believed that illness was the main cause of death, so if one could avoid sickness, one might avoid death altogether. Since medicine could cure diseases, could there exist a miraculous pill that could cure all ailments, granting eternal life? Since immortals were believed to live forever, they must have consumed an elixir of immortality. Therefore, if one could establish a good relationship with these immortals, one might share their secret to eternal life. Thus, during the Warring States period, alchemists traveled to the mythical islands of Penglai, Fangzhang, and Yingzhou off the coast of Yan and Qi in search of the elixir of immortality. In the south, records in the “Strategies of the Warring States” and “Hanfeizi” mention someone offering the King of Chu a “pill of immortality.” Later, Emperors Qin Shi Huang and Han Wudi spared no expense in grand quests to seek immortals and offer sacrifices to deities in pursuit of the elixir of immortality, though the results were predictable. Did the elixir of immortality actually exist? Could humans truly communicate with immortals?

At this time, people began to notice that certain herbs could not only cure illnesses but also extend life to some extent. Today we know that herbs can cure diseases because they kill bacteria in the human body. However, in ancient times, people believed that consuming medicine transferred the properties of the medicine to oneself. For example, if someone ate “the strength of nine oxen and two tigers,” they would possess that strength. This led to the earliest, unrefined forms of elixirs. Over time, people found that the effects of consuming herbs were not very pronounced. They realized that herbs, when stored for long periods, would dry out and decay, and when boiled or burned, would turn to ash. If the herbs themselves could not escape death, how could they grant eternal life to humans? Thus, people began searching for substances that inherently possessed the quality of immortality. After extensive searching, they discovered substances such cinnabar, lead, mercury, and gold.

Cinnabar is a red solid mineral; mercury (quicksilver) is derived from cinnabar and can be transformed back into cinnabar when burned. While this is a scientific fact today, it was once considered inexplicable by ancient people. They were fascinated by the mysterious properties of cinnabar and mercury, which seemed to change form but retain their essential nature. This led them to associate these substances with immortals who could transform yet remain unchanged themselves. Thus, ancient people attributed profound mystery to cinnabar and held it in the highest esteem. Alchemists stopped seeking immortals at sea, and people abandoned the practice of consuming herbal medicines for longevity, turning instead to setting up furnaces and cauldrons to refine and consume mineral-based elixirs. Thus, the earliest ideas of alchemy began to take root.

From historical records, around the time of Emperor Wu of Han, there were already accounts of refining cinnabar into gold. It was also said that Liu An, the King of Huainan, gathered a group of alchemists to set up cauldrons and create elixirs. When the elixir was completed, Liu An and his family consumed it and immediately ascended to heaven in broad daylight. Even the chickens and dogs at his home, having eaten the leftover medicine on the ground, transformed into immortal chickens and dogs and followed their master to heaven. This is the origin of the saying “even the chickens and dogs ascend to heaven.” Although this is just a legend, it indicates that alchemical practices had already reached a significant scale at that time. During the Eastern Han Dynasty, numerous alchemical writings circulated in society. One of the most famous was the “Zhouyi Cantong Qi” written by Wei Boyang, a Taoist alchemist from Shangyu, Kuaiji (now part of Zhejiang). This is the world’s earliest alchemical text and had a profound influence on later generations, earning it the title “King of All Elixir Classics.”

After the establishment of Taoism, there was a heightened focus on human life. While Taoist practitioners conducted rituals to pray for divine blessings and ward off evil spirits, they also sought methods for health, longevity, and even immortality. The practices and theories of alchemists inspired Taoism, and thus Taoist priests directly inherited the alchemical legacy of the alchemists, beginning the arduous journey of Taoist external alchemy. From the Wei and Jin dynasties to the Ming and Qing dynasties, Taoist priests were constantly seen working around alchemical furnaces. Alchemy was most popular during the Wei and Jin dynasties up to the Song dynasty, reaching its peak in the Tang dynasty.

The Wei, Jin, and Northern and Southern Dynasties marked a period of development for alchemy. During the Jin dynasty, a master alchemist named Ge Hong emerged, strongly advocating the consumption of golden elixirs, which he considered the most crucial technique for becoming an immortal. He formed a major Taoist sect known as the Dan Ding Daoist school. Ge Hong conducted systematic research and organization of previously circulated alchemical texts and, based on his years of practical alchemical experience, authored the book “Baopuzi Neipian,” which encapsulated his achievements in alchemy. He was later revered as the “Golden Elixir Immortal Master.” During the Northern and Southern Dynasties, many emperors and officials aspired to consume golden elixirs for longevity, leading to the emergence of many renowned alchemists. For example, Tao Hongjing, a famous Taoist of the Qi and Liang dynasties, once created elixirs for Emperor Wu of Liang. Historical records state, “The emperor took the flying elixir and found it effective, thus holding him in even higher regard.” Tao Hongjing conducted alchemical practices in Maoshan for over 20 years, gaining extensive experience and authoring several alchemical works, further promoting the practice of alchemy.

The Tang dynasty marked the peak of alchemical development. From the emperor down to ordinary scholars and poets, almost everyone was swept up in the craze for refining and consuming elixirs. The Tang dynasty strongly promoted Taoism, leading to a widespread pursuit of immortality. At that time, the nation was prosperous and wealthy, providing ample financial resources for alchemists to experiment with their furnaces. As a result, alchemy flourished during the Tang dynasty. This was not only evident in the increasingly sophisticated methods, equipment, and types of minerals used in alchemy but also in the emergence of many famous alchemists, such as Sun Simiao, Chen Shaowei, and Zhang Guo. Sun Simiao was both a medical expert and an alchemist, authoring several specialized works on external alchemy, such as “Taqing Zhenren Lian Yunmu Jue” and “Shao Lian Mi Jue.” Chen Shaowei authored works like “Xiu Fu Ling Sha Miao Jue.” Zhang Guo was a Taoist who practiced both internal and external alchemy, with external alchemical works such as “Dan Sha Jue.” During the Tang dynasty, a groundbreaking work on external alchemy, “Shi Yao Er Ya,” was written by Mei Biao, a Taoist mineralogist from Sichuan. This was a specialized work that annotated the names of mineral medicines. For a long time, alchemists deliberately made the formulas and medicine names strange and obscure, using cryptic terms that were difficult to understand without direct instruction from a master. “Shi Yao Er Ya” collected over 150 commonly used medicinal names in alchemy, listing the cryptic and alternative names under the common names of each medicine. For example, under “mercury,” there were as many as 21 cryptic or alternative names, making it an important reference book for alchemists.

However, most elixirs were toxic, and during the Tang dynasty, the widespread consumption of golden elixirs led to numerous cases of poisoning and death. As many as six Tang emperors died from poisoning due to consuming golden elixirs, an unprecedented number in Chinese history, including the famous “heroic ruler” Emperor Taizong of Tang, Li Shimin. After consuming the elixirs, the toxicity would cause erratic mood swings, leading to their deaths shortly afterward. The most tragic case was Zhu Quanzhong, the founding emperor of the Later Liang dynasty in the Five Dynasties period, who suffered acute mercury poisoning after consuming a golden elixir, causing his eyebrows and hair to fall out and leading to abscesses on his head and back that eventually caused his death. Alchemists explained such deaths as “corpse dissolution,” claiming that the person had already ascended to become an immortal, leaving behind only a physical shell. These explanations were steeped in Taoist beliefs. However, the victims of elixir poisoning were often emperors and high officials, and the painful and tragic deaths caused by elixir poisoning were real and undeniable. No matter how cleverly these incidents were explained through myths, people began to doubt the effectiveness of elixirs in granting longevity. The golden elixirs were dangerous! Although there were still many people refining elixirs after the Song dynasty, fewer dared to try them. Thus, the practice of external alchemy, which had flourished for centuries with the goal of achieving longevity through elixir consumption, began to decline. From then on, internal alchemy, which focused on self-cultivation, became popular, while external alchemy was dismissed as heretical and fell out of favor.

II. Chemical Experiments in Smoke and Fire

The practice of refining external elixirs was mixed with a great deal of fantasy. Although the subjective wish for immortality was not realized, over centuries of practice, a significant amount of chemical knowledge was accumulated. When Taoist alchemists solemnly set up stoves and cauldrons deep in the mountains, burning metals and refining elixirs amidst smoke and fire, they were unaware that they were actually engaging in pioneering work in the history of chemistry.

The chemical science that benefits humanity today can trace its origins back to alchemy, which deserves to be called its ancestor. Alchemy was introduced to Europe by the Arabs in the 8th century and became a precursor to modern experimental chemistry.

(1) Alchemical Materials

In Taoist alchemical practices, several substances held particularly important positions: cinnabar, mercury, gold, and lead.

Inventions from the Alchemy Furnace
(Seeking immortality, refining elixirs, chemical experiments amidst smoke and fire, and the accidental invention of gunpowder)

It is well known that gunpowder, along with papermaking, printing, and the compass, is hailed as one of China’s Four Great Inventions. These innovations later spread to Europe via Arab countries, playing a significant role in the development of human civilization. However, even today, many may not realize that gunpowder originated from the alchemy furnaces of Chinese Taoist priests or that its invention is linked to Taoist alchemy. To understand this, we must first delve into the practice of Taoist alchemy.

### I. Seeking Immortality: Refining External Elixirs
Taoism is a religion that celebrates life, values rebirth, and emphasizes techniques. One of its core beliefs is the pursuit of immortality. While death is inevitable, the idea of eternal life remains a cherished human aspiration. Taoism, however, relentlessly pursued this goal. Was there a method to achieve immortality? Taoism claimed there was: refining external elixirs for consumption was one of their primary methods.

Before Taoism emerged, the seeds of external elixir refinement had already been sown. As early as the Spring and Autumn and Warring States periods, people sought ways to prolong life and avoid death. They reasoned that normal death resulted from illness—what if one never fell ill? Medicine could cure diseases, so perhaps there was a panacea that could prevent illness and grant immortality. Legends spoke of immortals who lived forever, presumably by consuming such elixirs. Thus, during the Warring States era, alchemists ventured to the mythical islands of Penglai, Fangzhang, and Yingzhou in search of these elixirs. Historical records like the *Strategies of the Warring States* and *Han Feizi* mention offerings of “elixirs of immortality” to kings. Emperors like Qin Shi Huang and Han Wu Di invested heavily in quests for these elixirs, though their efforts proved futile. Did such elixirs truly exist? Could mortals truly communicate with immortals?

People then turned to herbs, which could cure diseases and, to some extent, prolong life. Modern science explains that herbs kill pathogens, but ancient beliefs held that consuming herbs transferred their properties to the consumer—akin to gaining the strength of nine oxen and two tigers by eating them. This led to the earliest unrefined elixirs. Over time, however, the effects of herbal consumption proved underwhelming. Herbs withered, decayed, or turned to ash when burned—how could they grant immortality? Thus, the search shifted to substances inherently “immortal.” Eventually, cinnabar, lead, mercury, and gold were identified.

Cinnabar, a red mineral, yielded mercury when heated, which could revert to cinnabar upon further heating. While this is basic chemistry today, ancient minds found it miraculous, associating it with shape-shifting immortals. This mystique elevated cinnabar to sacred status. Alchemists abandoned sea voyages in favor of refining cinnabar and other minerals in furnaces, marking the birth of primitive alchemy.

Historical records suggest that by Emperor Wu of Han’s reign, cinnabar was being refined into gold. Legends tell of Liu An, Prince of Huainan, who gathered alchemists to refine elixirs. Upon consuming the elixir, he and his family ascended to heaven, followed by their pets—a tale dubbed “even dogs and chickens ascend to heaven.” While mythical, it hints at alchemy’s growing sophistication. By the Eastern Han Dynasty, alchemical texts like *Zhouyi Cantongqi* by Wei Boyang, the “King of Alchemical Classics,” circulated widely.

Taoism’s founding intensified the quest for immortality. Taoists inherited and expanded alchemical practices, embarking on a centuries-long journey from the Wei-Jin to Ming-Qing periods, with the Tang Dynasty marking its zenith.

The Wei-Jin and Northern-Southern Dynasties saw alchemy flourish. Ge Hong, a master alchemist, championed elixir consumption, forming the Dan Ding Taoist school. His *Baopuzi Neipian* summarized alchemical achievements, earning him the title “Immortal of the Golden Elixir.” Emperors and nobles eagerly consumed elixirs, spawning renowned alchemists like Tao Hongjing, who refined elixirs for Emperor Wu of Liang.

The Tang Dynasty was alchemy’s golden age, with everyone from emperors to poets caught in the elixir craze. Prosperity fueled lavish alchemical experiments, yielding advanced methods, equipment, and minerals. Notable alchemists like Sun Simiao, Chen Shaowei, and Zhang Guo emerged. Sun, both a physician and alchemist, authored texts like *Taishang Zhenren Lian Yunmu Jue*. Zhang Guo’s *Dansha Jue* and Mei Biao’s *Shiyao Erya*, a glossary of alchemical terms, were groundbreaking.

Yet elixirs were often toxic. Tang emperors, including the illustrious Taizong, died from elixir poisoning. The tragic death of Later Liang’s Emperor Zhu Quanzhong, whose body rotted after ingestion, starkly exposed elixirs’ dangers. Alchemists dismissed such deaths as “corpse liberation”—ascension leaving only a shell. Despite these rationalizations, skepticism grew. By the Song Dynasty, elixir consumption waned, and internal alchemy (self-cultivation) replaced external practices.

### II. Chemical Experiments Amidst Smoke and Fire
Though alchemy’s dream of immortality failed, its millennia-long practice birthed foundational chemistry. Unbeknownst to them, Taoist alchemists conducting smoky, fiery experiments pioneered chemical science.

Modern chemistry traces its roots to alchemy, which spread to Europe via Arabs in the 8th century, becoming the precursor to experimental chemistry.

#### (1) Alchemical Ingredients
Key substances in Taoist alchemy included cinnabar, mercury, gold, and lead.

**Cinnabar (HgS)**, or vermilion, was the premier alchemical material. Ge Hong noted its transformative properties: “The longer it’s heated, the more marvelous its changes.” Alchemists extracted mercury from cinnabar, then combined it with metals to form amalgams. The reactions:
1. HgS + O₂ → Hg + SO₂ (starting at 285°C)
2. Hg + ½O₂ → HgO (red mercuric oxide, resembling cinnabar)

Ge Hong summarized: “Cinnabar heated becomes mercury; mercury transformed reverts to cinnabar.”

**Mercury**, a liquid metal, was used to create amalgams, notably lead-mercury compounds (“Xuanhuang”). Alchemists also synthesized mercuric chloride (HgCl₂) and mercurous chloride (Hg₂Cl₂), a milestone in inorganic chemistry.

**Gold**, revered for its incorruptibility, was believed to confer longevity. Initially, alchemists consumed “elixir gold” (alloys), but its toxicity led to attempts with pure gold—equally fatal.

**Lead**, though common, fascinated alchemists for its color-changing oxides like minium (Pb₃O₄), dubbed “divine elixirs.”

#### (2) Alchemical Methods
Elixirs varied, but two primary methods existed: **pyrometallurgy** (fire-based) and **hydrometallurgy** (water-based).

Thus, amidst their quest for immortality, Taoist alchemists unwittingly laid the groundwork for chemistry, leaving a legacy that transcended their mystical aims.

HgS + O2 → Hg + SO2 (1)

Hg + 1/2 O2 → HgO (2)

Equation (1) represents the oxidation reaction of cinnabar (HgS, mercuric sulfide) when heated, producing mercury (Hg) and sulfur dioxide (SO2), which is the so-called transformation of cinnabar into mercury. This reaction begins at 285°C but must not be heated too intensely, as the boiling point of mercury is only 357°C. Equation (2) indicates that continued heating causes mercury to undergo an oxidation reaction, producing mercuric oxide (HgO). Mercuric oxide is red in color and resembles cinnabar in appearance, leading to the mistaken belief that it had been transformed back into cinnabar. Ge Hong provided a concise summary of these two reactions in “Baopuzi Neipian: Jin Dan”: “Cinnabar, when burned, becomes mercury; through further transformation, it reverts back to cinnabar.”

Since mercuric sulfide easily evaporates when heated, the reaction vessel must be sealed, especially to control the reaction temperature, commonly referred to as mastering the right timing of the fire. Without precise instruments in ancient times, the temperature control in the alchemical furnace was entirely based on the alchemist’s intuitive experience, requiring repeated experimentation to master. Therefore, the control of fire timing was considered a secret by alchemists. In the alchemical process, since cinnabar was sourced from nature and contained many impurities, the actual chemical reaction process was more complex and harder to control.

Mercury, also known as quicksilver, is a white liquid substance. After extracting mercury from cinnabar, alchemists combined it with various metals to form amalgam alloys for consumption. Among these, lead-mercury compounds, known in ancient times as “Xuan Huang” or “Huang Jing,” were the most famous and were the “Great Elixirs” that alchemists longed for. Through long-term practice, alchemists also discovered methods to synthesize two chlorides using mercury: mercuric chloride and mercurous chloride, both of which could be used medicinally for consumption. According to research by chemists, the synthesis of mercuric chloride represents an important contribution of Chinese alchemy and medical chemistry to inorganic synthesis chemistry.

Gold held a position second only to cinnabar in the alchemists’ medicinal materials. Gold is soft and highly malleable, and among the metals known at the time, it was considered the most chemically stable. The ancients believed that gold’s nature was imperishable, making it the treasure of all things, and consuming it could prolong life, transferring the properties of gold to the human body. Thus, alchemists revered gold greatly. However, the gold initially consumed by alchemists was not real gold but “spiritual gold liquid,” or artificial gold, extracted after refining cinnabar and gold together. Later, people discovered that consuming “spiritual gold liquid” not only failed to extend life but also frequently caused poisoning and death. Therefore, after the Tang dynasty, people began consuming real gold, although the results were not much better.

Lead is a very common metal, but in the eyes of Chinese alchemists, it was as important as cinnabar and gold in the practice of alchemy. Lead appears dark and black on the outside but is bright inside. During the refining process, it can exhibit different colors depending on the temperature and degree of oxidation, which fascinated the ancients and aligned with their belief that “the form changes but the essence remains unchanged.” When lead is oxidized, it becomes lead tetroxide (Pb3O4), also known as yellow lead, which appears yellow-orange or red at room temperature and turns purple when heated. The “Shennong Bencao Jing” regarded lead tetroxide as a substance that could “refine and transform into nine lights, and long-term consumption could lead to spiritual enlightenment.” Alchemists considered it a “miraculous elixir.”

(2) Alchemical Methods

In Taoist alchemy, there were many types of elixirs made from substances such as cinnabar, mercury, gold, and lead, and numerous methods for producing these elixirs. These methods included the Minshan Elixir Method, the Wuchengzi Elixir Method, and the Xianmenzi Elixir Method, among others. However, the basic methods can be broadly categorized into two: fire-based alchemy and water-based alchemy.

Fire-based alchemy involves heating solid substances such as cinnabar in furnaces to induce chemical reactions that produce elixirs. This includes processes like distillation, sublimation, combination, and various fire-control techniques. Alchemists used distillation to extract mercury from cinnabar, known as “extracting mercury from cinnabar.” Sublimation and combination were often used together with grinding techniques. For example, when mercury reacted with metals to form amalgams, the metals were first ground into powder or small particles, making them easier to combine with mercury through grinding. Various fire-control methods were frequently employed by alchemists, including nurturing fire, controlling fire, heating, roasting, calcining, and more. Though numerous in name, their fundamental purpose was to heat the substances to alter their properties and achieve specific medicinal effects.

Water-based alchemy involves dissolving medicinal substances into liquid so that chemical reactions can occur. Many methods were employed in water-based alchemy. Ge Hong’s writings recorded techniques such as the “cinnabar water method,” “realgar water method,” and “alum water method.” For example, the cinnabar water method required potassium nitrate (KNO₃) and acetic acid (CH₃COOH), along with copper sulfate (CuSO₄) as a catalyst to transform cinnabar into liquid. The reaction is as follows:

3HgS + 8KNO₃ + 8CH₃COOH — CuSO₄ → 3(CH₃COO)₃Hg + 3K₂SO₄ + 8NO + 2CH₃COOK + 4H₂O

This method, which combined acid-base reactions with oxidation-reduction reactions, was a major innovation in ancient Chinese alchemical chemistry. In water-based alchemy, alchemists also paid attention to controlling temperature to increase solubility, ensuring that the substances were completely dissolved to meet the standards required for internal consumption.

(3) Pioneers of Experimental Chemistry

For over a thousand years, alchemists used these methods deep in mountains or within secluded walled compounds, setting up furnaces and cauldrons, burning night oil, unaware of how many sleepless nights they endured and how many times they experienced frustration and joy in their experiments. Guided by misguided beliefs, their practices appeared absurd and filled with devout fantasies. Yet, in the history of science, they became pioneers of experimental chemistry.

Firstly, the specific knowledge alchemists accumulated about material transformations cannot be ignored. They imagined that base metals could be turned into gold and silver, that mercury could be transformed into gold, and that various metallic and mineral substances could be combined to synthesize or decompose into new substances. Such ideas were unprecedented in human history. Though fantastical, they aligned closely with modern chemistry.

Secondly, alchemists conducted long-term, extensive experiments in rooms filled with toxic fumes, exploring the raw materials and formulations needed to create elixirs, as well as operational methods, especially heating procedures and temperature control. All of these were primitive forms of chemical experimentation.

Thirdly, through long-term experimentation, alchemists gradually developed an understanding of the chemical properties of substances and learned methods to describe and identify different chemical substances. For example, we know that potassium salts burn with a purple flame, while sodium salts burn with a yellow flame. Tao Hongjing recorded a flame test for nitre (potassium nitrate, KNO₃), stating that when strongly burned, it produced “purple-blue smoke.” Even today, we still use flame color tests in laboratories to distinguish substances. For Tao Hongjing, living over 1,400 years ago, to have mastered this method was truly remarkable.

III. The Accidental Invention of Gunpowder

The invention of gunpowder is closely related to Daoist alchemy. Besides pioneering experimental chemistry, alchemists inadvertently discovered gunpowder during their attempts to create elixirs.

We know that the original formula for gunpowder consists of sulfur (S), potassium nitrate (KNO₃), and charcoal (C), ground into powder and mixed together. Sulfur and potassium nitrate were two mineral substances commonly used in water-based alchemy. Alchemists believed these substances contained “fiery toxins” harmful to the internal organs. Before using them in water-based alchemy, they needed to neutralize these toxins by heating, a process known as “fire suppression” or “using poison to counter poison.” During this process, slight mishandling could lead to intense combustion or explosions, resulting in accidents. It was precisely through such accidents that alchemists discovered the original formula for gunpowder.

In ancient times, the materials used for fire suppression roughly fell into three categories:

First was a mixture of potassium nitrate, pork intestines, pine resin, and realgar to neutralize the fire toxins. Pork intestines and pine resin, when heated and carbonized, functioned similarly to charcoal, while realgar contained sulfur. This formula was almost identical to modern black powder. The specific method is recorded in Ge Hong’s “Baopuzi Xianyao.”

Second was a mixture of sulfur, realgar, potassium nitrate, and honey. Honey acted similarly to charcoal, combining with sulfur and potassium nitrate to form a combustible mixture capable of intense burning.

Third was a mixture of sulfur, potassium nitrate, and soapnut seeds. Sun Simiao’s “Danjing” recorded the specific method: burying a clay pot or silver-melting crucible in the ground, filling the surrounding area with soil, placing two ounces each of potassium nitrate and sulfur into the pot, adding soapnut seeds, and igniting them. The smoldering soapnut seeds would ignite the potassium nitrate and sulfur, effectively creating black powder.

During fire suppression, precise control over the proportions of ingredients and the heating process was essential; otherwise, combustion or explosion could occur. A Tang Dynasty alchemical text, “Zhenyuan Miaodao Yaolue,” attributed to Zheng Siyuan, records an incident where someone combined sulfur, realgar, potassium nitrate, and honey and heated them, causing a fire that burned their hands and face and destroyed their house. The text warns: “Potassium nitrate… should never be heated together with the ‘three yellows’; doing so will immediately bring disaster.” In other words, potassium nitrate and sulfur should not be burned together. This record was the first historical documentation linking gunpowder’s invention closely to alchemy, likely prompted by numerous such accidents experienced by alchemists. British historian of science Joseph Needham noted that the earliest written mention of gunpowder in any civilization appears in the Daoist alchemical text “Zhenyuan Miaodao Yaolue.”

At first glance, gunpowder’s formula seems to be an accidental discovery by alchemists. However, it was actually the result of their long-term, painstaking experiments, achieved at great cost. Later, people transformed this danger into utility, refining the formula to change violent combustion into explosive force, applying it to daily life and military use, creating fireworks and the precursors to later firearms—tube-shaped weapons. Thus, the gunpowder accidentally discovered by Daoist priests finally created a seismic impact on society.

By the 8th and 9th centuries, gunpowder was already being used in warfare. By the 9th to 10th centuries, rockets and fireballs emerged as offensive weapons. By the 1330s, tube-shaped firearms had appeared. The Jurchens and Mongols learned and improved upon these weapons during warfare. During Genghis Khan’s western campaigns in the 12th century, cannons were already in use. Gunpowder, originally used in Daoist furnaces, spread westward to the Arab world, and from there Europeans learned to manufacture and use it, turning it into a powerful tool for conquest. This outcome was something the Daoist practitioners, who sought immortality in the smoke-filled furnaces, could never have imagined.

Chemical Achievements in Ancient Alchemy

Modern chemistry, now highly developed, has not only uncovered the secrets of material transformation but also created many artificial substances not found in nature. It has essentially achieved the ancient dream of “controlling the forces of nature.” However, we know that this science, like all human knowledge, began in an immature stage—the primitive form of chemistry known as alchemy or alchemy, as Engels described it.

Alchemy was an ancient practice aimed at creating elixirs for immortality. This practice originated early in China. According to the “Biography of Liu Xiang” in the “History of the Han Dynasty,” Prince Liu An of Huainan (179–122 BCE) mentioned in his “Zhenzhong Hongbao Miyuan Shu” that during the Warring States period, Zou Yan (circa 305–240 BCE) had a formula called “Chongzhui Yanming Fang,” which may have been the earliest recorded alchemical formula in China. However, this formula was not passed down, and Liu An’s book has long been lost, making its contents unknown. Nevertheless, the “Strategies of the Warring States” records a story of a Daoist practitioner offering an “elixir of immortality” to King Jing of Chu. The “Records of the Grand Historian” details Emperor Qin Shi Huang’s pursuit of “immortal medicine” and his dispatch of Xu Fu with thousands of young men and women to seek immortals at sea. These accounts show that alchemy had already begun to take root in China during the pre-Qin period. By the Western Han Dynasty, Emperor Wu (156–87 BCE) pursued immortality on an even larger scale, following the advice of the alchemist Li Shaojun to set up an alchemical furnace in the palace and personally engage in alchemical practices. From then on, alchemy became popular among the feudal ruling class and remained so until the Song and Yuan dynasties. Thus, throughout history, many practitioners emerged—those we now call alchemists.

Ancient Chinese alchemical practices (excluding “internal alchemy” aimed at physical cultivation) involved many fields of natural science, but its main content can be summarized into three areas:

First, the use of various inorganic substances, including minerals and metals, to create longevity medicines through chemical processing.

Second, metallurgical research aimed at producing artificial “gold” and “silver” for medicinal purposes.

Third, the study of medicinal plants in the search for plant-based longevity medicines.

The goals of alchemy were fantastical, and its theories largely belonged to idealism and superstition. This is why, after more than a thousand years of development, it eventually gave way to traditional Chinese pharmacology (which included pharmaceutical chemistry). However, based on the knowledge accumulated by the working people through production and struggle, alchemists personally collected and prepared medicines, conducted various experiments, and observed natural phenomena. These practices enabled them to achieve many significant accomplishments in science and technology, especially in chemistry, leaving behind a precious legacy for future generations.

Fire-Based Alchemy

Ancient Chinese alchemical methods can be divided into fire-based and water-based techniques. Fire-based methods primarily involved heating substances without water, resembling metallurgy. In the Eastern Han Dynasty, the alchemist Wei Boyang mentioned in his book “Zhouyi Cantong Qi” that there were 600 chapters on fire methods, referring to these fire-based techniques. However, this book has long been lost, and its content is unknown. According to records in Ge Hong’s “Baopuzi Neipian” from the Jin Dynasty and later alchemical writings, fire-based methods generally included calcining (prolonged high-temperature heating), roasting (heating dry substances), baking (localized heating), melting, distillation, sublimation (also known as “flying”), and “fu” (heating to alter the properties of substances).

The earliest material studied in alchemy may have been cinnabar, or red mercuric sulfide, using fire-based methods. When heated, red mercuric sulfide decomposes into mercury (quicksilver), which combines with sulfur to form black mercuric sulfide. When heated again and sublimated, it reverts to red mercuric sulfide. The resulting mercury, a metallic substance in liquid form, is fluid and volatile, making it seem different from ordinary substances. All these phenomena fascinated the ancients, leading alchemists to try to use these substances to create “returning elixirs” or “spiritual elixirs” with miraculous effects. The “Baopuzi Jindan Pian” states: “Once the spiritual elixir is made, it not only grants immortality but also turns base metals into gold.” In other words, the “spiritual elixir” was believed to both grant immortality and transform base metals into gold. Ancient alchemists repeatedly experimented with mercury to create the “Nine Transformations Returning Elixir,” becoming very familiar with these transformations. In the Western Han Dynasty, Liu An wrote in “Huainan Wanbishu” that “cinnabar becomes mercury.” In the Eastern Han Dynasty, Wei Boyang’s “Zhouyi Cantong Qi” vividly described mercury’s volatility and its tendency to combine with sulfur, and how it would sublime in the cauldron and “return to cinnabar.” Ge Hong of the Jin Dynasty summarized these observations in one sentence in his “Baopuzi Jindan Pian”: “Cinnabar burns into mercury, which, through transformation, returns to cinnabar.” These conclusions were drawn from long-term experimentation. By the Tang Dynasty, Chen Shaowei’s “Jiuhuan Jindan Miaojue” recorded a precise method for “converting mercury into cinnabar,” specifying exact proportions of mercury and sulfur, controlled heating, and a specific procedure, ultimately achieving the result of “turning into purple cinnabar without any loss.” Compared to modern chemistry, this method was already very close. Red mercuric sulfide exists in both natural and artificial forms—natural cinnabar (called Chen cinnabar when produced in Hunan) and artificial red mercuric sulfide, known as silver vermilion or ling cinnabar. Artificial red mercuric sulfide was one of the earliest chemical synthesis products created by humans, marking a significant achievement in alchemical chemistry.

Because alchemists studied mercury transformations from early times, they also researched other mercury compounds. For example, the Tang Dynasty alchemical text “Taiping Shibi Ji” recorded a method for producing “mercury frost” (mercurous chloride or mercuric chloride). The method involved heating mercury and tin at different temperatures to form a tin-mercury amalgam, which was then crushed and mixed with salt, along with “taiyin xuanjing” (magnesium chloride), “Dunhuang fan stone” (coarse gypsum), or “tao fan” (iron-containing coarse gypsum). Sodium sulfate was placed on top, and the mixture was heated for seven days and nights. Today, we understand that heating mercury with sodium chloride and sodium sulfate can produce mercuric chloride, which then reacts with excess mercury to form mercurous chloride. This method was complex, and later methods for producing mercury frost became simpler.

The ancients had long noticed the amalgamation effect of mercury with other metals in their alchemical practices. Wei Boyang’s description of “suddenly obtaining golden essence, which then transforms into a white liquid and solidifies into hardness” refers precisely to this property of mercury. The amalgams they produced included not only tin amalgam but also those of gold, silver, lead, and other metals. Liu An’s *Huainanzi·Xiushu Xun* mentions that “bright mirrors” required “powdering with dark tin,” where “dark tin” refers to lead amalgam, used in ancient times as a polishing agent for copper mirrors. Tao Hongjing of the Northern and Southern Dynasties noted that mercury “can dissolve gold and silver into a paste, which people use for plating.” This indicates that the method of producing gold and silver amalgams was already widely used in production by that time.

The *Zhujia Shenpin Danfa* from the Song Dynasty contains the “Method of Transforming Gold into Powder,” which utilized gold amalgam to produce gold powder: first, gold amalgam was made, then salt was added, and after evaporating the mercury and dissolving the salt, what remained was powdered gold. The *Ganqi Shiliu Zhuan Jindan* from the Song Dynasty describes the “Fourteenth Transformation Purple River Chariot Method”: four taels of cinnabar, four taels of realgar, and two taels of raw mercury were ground into powder, sealed in a furnace, and heated for sixty days to produce the so-called “Purple River Chariot.” A small amount of this substance could “dry one tael of mercury, turning it yellow.” Some have interpreted this reaction as follows: the three substances, when heated, might form a reddish-brown solid solution (Purple River Chariot), and adding a small amount of this to mercury could transform the mercury into a yellow solid solution. It is understandable that ancient alchemists studied these reactions of mercury in search of a “divine elixir” capable of “transmuting” mercury into gold. Under the conditions of their time, such aspirations were unattainable, yet their experiments expanded humanity’s understanding of natural phenomena.

Metallic lead and its compounds appeared very early in China. By the Han Dynasty, Chinese laborers had already begun producing cosmetic powder, known as basic lead carbonate (*hubai*, meaning “face powder,” not “foreign powder,” as clarified by Liu Xi in *Shiming*). The *Zhouyi Cantong Qi* notes, “When *hubai* is thrown into fire, its color fades and it reverts to lead.” This transformation caught the attention of alchemists, who made it a key subject of study. Beyond using lead to create lead amalgam, they also prepared red lead (lead tetroxide). The *Baopuzi·Huangbai Pian* states, “Lead is white, yet when heated, it turns red as cinnabar; cinnabar is red, yet when whitened, it reverts to lead.” This suggests that lead was not only used to produce white *hubai* but also red cinnabar, which, when thrown into fire, would similarly “fade and revert to lead.” Later alchemists conducted extensive research on lead compounds. For example, Qingxuzi’s *Qian Gong Jia Geng Zhi Bao Ji Cheng* from the Tang Dynasty includes a “Method of Making Cinnabar,” where lead, sulfur, and saltpeter were melted and treated with vinegar to produce a powder called “yellow lead powder,” likely impure lead acetate.

The *Zhouyi Cantong Qi* declares, “Gold does not decay; thus, it is the treasure of all things.” Alchemists believed that consuming “indestructible” substances like gold and silver could render the human body similarly “indestructible.” Consequently, they sought not only to ingest these materials but also to artificially produce medicinal gold and silver. From Emperor Wu of Han and Liu An onward, many emperors, nobles, and wealthy families employed alchemists to produce gold for them. While this goal was unattainable at the time, their experiments, built upon the production experience of laborers, led to numerous innovations in metallurgy. Ge Hong’s *Baopuzi·Huangbai Pian* mentions that in his era, alchemists possessed the *Shenxian Jing Huangbai Zhi Fang*, a 25-volume work containing over a thousand prescriptions, as well as the *Huangbai Zhongjing*, all detailing methods of producing “gold” and “silver”—collectively known as the “Yellow and White Art.” He also noted that tin, lead, and mercury could be transformed into “gold” and “silver” using medicinal substances, indicating that Jin Dynasty alchemists had already mastered the production of various yellow or white alloys from base metals. Tao Hongjing’s *Mingyi Bielu* from the Northern and Southern Dynasties states that realgar “when combined with copper, can produce gold,” suggesting that alchemists of that time knew how to use arsenic-containing minerals to produce copper-arsenic alloys. By the Tang and Five Dynasties periods, the *Baozang Lun* records fifteen types of counterfeit gold and twelve types of counterfeit silver circulating in the market, all produced through medicinal “transmutation.” This alchemical pursuit flourished in ancient China, persisting even into the Song Dynasty, when Emperor Zhenzong ordered the alchemist Wang Jie to produce “crow-beak gold” from iron, which was then cast into “gold” turtles and plaques for his ministers.

Alchemists recognized the “violent toxicity” of substances like sulfur and arsenic trioxide and sought to “tame” (*fuhuo*) them through heating before use, reducing or eliminating their toxicity. This process, known as “fire subduing,” dates back to ancient times and sometimes involved adding flammable substances. Sun Simiao (581–682) of the early Tang Dynasty described a “Method of Subduing Sulfur”: two taels each of sulfur and saltpeter were ground into powder and placed in a stone pot, ignited with three soap pods (containing carbon), and after burning out, mixed with three catties of charcoal and stir-fried until one-third of the charcoal was consumed. During the Yuanhe era (806–820), the alchemist Qingxuzi devised a “Method of Subduing Alum,” using two taels each of saltpeter and sulfur and three and a half qian of birthwort (also containing carbon)—almost identical to Sun Simiao’s method. These “fire subduing” prescriptions invariably contained carbon, and sulfur subduing required saltpeter, while saltpeter subduing required sulfur, indicating that alchemists intentionally made the substances flammable to remove their “violent toxicity.” From a modern chemical perspective, the purpose of this process remains unclear. However, frequent laboratory fires caused by “fire subduing” experiments led Tang Dynasty alchemists to a crucial discovery: sulfur, saltpeter, and carbon could combine to form “gunpowder.” By the late Tang period, this formula had transitioned from alchemy to military use, becoming one of ancient China’s Four Great Inventions—black powder.

Another significant achievement of pyrometallurgical alchemy was the preparation of elemental arsenic. Ge Hong’s *Baopuzi·Xianyao Pian* records six methods for processing realgar, the last of which involved heating realgar (As₂S₂) with saltpeter (KNO₃), pig intestine (containing carbon), and pine resin. This process first produced arsenic trioxide (As₂O₃), which was then reduced to pure elemental arsenic through further heating with carbon-rich pig intestine and pine resin. This method, the world’s earliest known preparation of elemental arsenic, predates the work of the German alchemist Albertus Magnus (c. 1200–1280) by nine hundred years.

### Hydrometallurgical Alchemy

Ancient alchemists sought not only to refine solid elixirs but also to dissolve metallic substances into liquids. Through long-term experimentation with dissolving minerals, they accumulated considerable empirical knowledge of complex reactions in aqueous solutions. The *Daozang*’s *Dongshen Bu Zhongshu Lei* includes the *Thirty-Six Aqueous Methods*, likely a pre-Jin Dynasty work preserving fifty-four prescriptions for dissolving thirty-four minerals and two non-minerals. Ge Hong’s *Baopuzi·Jindan Pian* also records numerous similar prescriptions. Together with Tang and Song Dynasty records, these texts provide a glimpse into ancient hydrometallurgical alchemy.

Methods for processing substances in hydrometallurgical alchemy included:
– **Dissolution** (sometimes melting),
– **Leaching** (extracting part of a solid with water),
– **Sealing** (enclosing reactants for long-term storage or burial),
– **Boiling** (heating in large amounts of water),
– **Simmering** (prolonged high-temperature heating with water),
– **Stewing** (prolonged low-temperature heating),
– **Fermenting** (long-term exposure to moisture or carbon dioxide),
– **Spotting** (using small amounts of reagents to induce large-scale changes),
– **Pouring** (cooling by decanting solutions),
– **Quenching** (cooling with cold water externally),
as well as filtration and recrystallization.

To prepare substances hydrometallurgically, a *huachi* (a dissolution vat containing concentrated vinegar, sometimes replaced by jars or basins) was essential. Saltpeter and other substances were added to the vinegar. Saltpeter (originally *xiaoshi*, “stone dissolver”) was crucial in Chinese alchemy for its ability to “dissolve seventy-two minerals.” In acidic solutions, it provides nitrate ions, functioning similarly to dilute nitric acid, enabling the dissolution of many metals and minerals. Ancient alchemists deliberately added saltpeter to vinegar, a practice that, from a modern chemical perspective, unified acid-base and redox reactions—an innovative approach that remains useful today.

Some reactions conducted by alchemists in *huachi* were remarkably complex for pre-modern chemistry. For example:

1. **Dissolution of Gold**: The *Baopuzi·Jindan Pian* describes a “Gold Liquefaction Method” using vinegar, saltpeter, halite, and *xuanming longgao* (which, according to Tang Dynasty scholar Mei Biao’s *Shiyao Erya*, could refer to mercury or a mixture of vinegar and raspberry). The text claims that sealing gold with these substances in a *huachi* for a hundred days would slowly dissolve it into “water.” Modern chemistry confirms that gold is highly inert and dissolves only under specific conditions:
– In aqua regia or mixtures producing chlorine, bromine, or iodine;
– In chlorine water, forming gold trichloride;
– In mercury, forming gold amalgam (liquid when gold content ≤15%);
– In dilute alkali cyanide solutions with oxygen, forming dicyanoaurate(I) ions.
Given the ingredients, aqua regia or chlorine production is unlikely, but mercury or raspberry vinegar (containing hydrogen cyanide) aligns with the latter two methods. The presence of these gold-dissolving agents suggests extensive empirical experimentation.

2. **Dissolution of Sulfur**: The *Thirty-Six Aqueous Methods* includes a “Sulfur Water” made from sulfur, chalk, vinegar, and urine (ammonia), likely producing calcium polysulfide—a substance capable of discoloring metals, forming colored precipitates, and even corroding noble metals. Alchemists may have regarded this as a universal “divine elixir.”

Hydrometallurgical methods were diverse. The *Huangdi Jiuding Shendan Jingjue* describes a method for preparing potassium sulfate: dissolving *puxiao* (impure saltpeter) and saltpeter in hot water, evaporating the solution, and crystallizing the sulfate by cooling. This exploitation of differential solubility was another chemical innovation.

A further discovery was metal displacement in solution. Alchemists, driven by theories of metal “transmutation,” observed this phenomenon early. The *Huainan Fangbishu* from the Western Han notes that “when *zengqing* (copper sulfate) meets iron, it turns into copper.” Ge Hong of the Jin Dynasty observed that coating iron with *zengqing* turned its surface copper-colored. Tao Hongjing extended this to *jishituan* (basic copper carbonate or sulfate), noting its similarity to *zengqing* in producing “refined copper.” These experiments represent early, detailed descriptions of displacement reactions, though their interpretations were limited by contemporary knowledge. This discovery later evolved into the wet-metallurgical “vitriol method” for copper extraction.

### Substances Used in Alchemy

The materials and tools of alchemy contributed to the emergence of chemistry. However, distinguishing alchemical from medical usage is challenging, as many alchemists were also physicians, and vice versa. For instance, the *Shennong Bencao Jing* (Eastern Han), the oldest extant pharmacopoeia, classifies cinnabar as the foremost “upper-grade” substance and lists over forty alchemically significant minerals across three grades, defining “upper-grade” substances as those that “extend life, enable ascension to immortality…”—clearly alchemical in tone. Works by confirmed alchemist-physicians, such as Ge Hong’s *Zhouhou Beiji Fang*, Tao Hongjing’s *Mingyi Bielu*, and Sun Simiao’s *Qianjin Yifang*, further blur the line. Thus, while the following list includes substances used in alchemy, their origins may not always be alchemical.

(Note: Due to length constraints, the full translation has been condensed. The complete text would detail all substances and tools mentioned in the original passage.)

Lead and its compounds appeared very early in China. The Chinese working people were already producing “Hu Fen” (lead carbonate), used as a cosmetic powder, before the Han Dynasty. “Hu Fen” is a basic lead carbonate (Hu Fen refers to face powder, not powder for foreigners, as noted in Liu Xi’s “Shiming”). The “Zhouyi Cantong Qi” states, “When Hu Fen is placed in fire, its color changes and it reverts to lead.” This transformation attracted the attention of alchemists, who regarded it as one of their important research subjects. In addition to using lead to produce lead-mercury amalgams, they also used it to prepare “Huang Dan,” which is lead tetroxide. Ge Hong’s “Baopuzi Huangbai Pian” states, “Lead is naturally white, but when turned red it becomes cinnabar; cinnabar is naturally red, but when turned white it becomes lead.” This indicates that lead was not only used to produce white Hu Fen but also to produce red Huang Dan. When Huang Dan is placed in fire, it also “changes color and reverts to lead.” Later alchemists conducted extensive research on lead compounds. For example, in the Tang Dynasty text “Qian Gong Jia Geng Zhi Bao Ji Cheng” by Qing Xuzi, there is a method called “making cinnabar,” which involves melting lead, sulfur, and nitrate and then adding vinegar to produce a powder called “Huang Dan Hu Fen,” which may be impure lead acetate.

“Gold does not decay; thus, it is treasured among all things.” Alchemists believed that consuming “indestructible” substances like gold and silver could make the human body similarly indestructible. Therefore, they not only sought to consume these substances but also attempted to artificially produce medicinal gold and silver. From Emperor Liu Che and Liu An of the Han Dynasty onwards, many emperors, generals, and aristocrats summoned alchemists to produce gold for them. This goal could not be achieved at the time, but based on the practical experience of the working people, they indeed made many inventions and innovations in metallurgy. Ge Hong stated in the “Baopuzi Huangbai Pian” that during his time, alchemists possessed twenty-five volumes of “Shenxian Jing Huangbai Fang,” containing over a thousand formulas, as well as other texts like the “Huangbai Zhong Jing,” which discussed methods for producing “gold” and “silver,” known as the “Huangbai technique.” He also mentioned that tin, lead, and mercury could be transformed into “gold” and “silver” using medicinal substances, indicating that alchemists of the Jin Dynasty could already produce various yellow or white alloys from different base metals. During the Southern and Northern Dynasties, Tao Hongjing stated in the “Mingyi Bie Lu” that realgar “can be used to make gold with copper,” suggesting that alchemists of that time already knew how to produce copper-arsenic alloys. By the Tang and Five Dynasties periods, according to the “Baozang Lun,” there were fifteen kinds of counterfeit gold and twelve kinds of counterfeit silver circulating in the market, all produced through medicinal “pointing” and “transforming” techniques. This alchemical activity flourished in ancient China and continued until the Song Dynasty. Emperor Song Zhenzong Zhao Heng (968–1022) even ordered a Taoist adept, Wang Jie, to produce “crow’s beak gold” from iron, casting “gold” turtles and “gold” plaques to bestow upon his close ministers.

Alchemists treated substances like sulfur and arsenic trioxide, which were considered “highly toxic,” by first “taming” (subduing) them through fire, reducing or eliminating their inherent toxicity. This process was called “Fu Huo” (taming by fire). The origins of this method are ancient, and sometimes it involved only calcination, while at other times additional flammable substances were added. In the early Tang Dynasty, Sun Simiao (581–682) had a “Fu Liu Huang Fa” (method for taming sulfur): two liang each of sulfur and nitrate were ground into powder and placed in a stone pot, then ignited with three soap pods (carbon-containing), causing the sulfur and nitrate to burn. After the fire extinguished, three jin of charcoal (half raw and half cooked) were added and stir-fried until one-third of the charcoal was consumed. During the Yuanhe period of Emperor Xianzong of the Tang Dynasty (806–820), the alchemist Qing Xuzi had a “Fu Huo Fan Fa” (method for taming vitriol), using two liang each of nitrate and sulfur, and three qian and a half of horse chestnut (carbon-containing), almost identical to Sun Simiao’s “Fu Liu Huang Fa.” These “Fu Huo” formulas contained carbon, and sulfur was tamed with nitrate, while nitrate was tamed with sulfur, indicating that alchemists intentionally caused the substances to ignite and burn to remove their “malignant toxicity.” However, from a modern chemical perspective, the purpose of this treatment is not very clear. Nevertheless, frequent accidents caused by “Fu Huo” procedures led Tang Dynasty alchemists to gain an important insight: sulfur, nitrate, and carbon could form a “gunpowder.” Around the late Tang Dynasty, this formula was adopted by military strategists, leading to the invention of black gunpowder, one of China’s four great inventions.

Another significant achievement of fire-based alchemy was the preparation of elemental arsenic. Ge Hong’s “Baopuzi Xianyao Pian” recorded six methods for processing realgar, with the final method involving the use of nitrate, black pork intestine (pig large intestine), and pine resin to “refine” it. When realgar (As₂S₂) and nitrate (KNO₃) are refined together, arsenic trioxide (As₂O₃) can be collected. Then, after refining twice with carbon-containing pig intestine and pine resin, it is reduced to pure elemental arsenic. This is the earliest known method for preparing elemental arsenic worldwide, predating the method used by the 13th-century German alchemist Albertus Magnus (approximately 1200–1280) by nine hundred years.

Hydrometallurgical Alchemy

Ancient alchemists not only aimed to transform mineral substances into solid elixirs but also sought to dissolve them into liquid forms. Thus, through long-term practice in dissolving mineral substances, they gained considerable empirical knowledge of complex reactions in aqueous solutions. The “Daozang” (Taoist Canon), in its “Dongshen Department Zhongshu Category,” contains the “Thirty-six Water Methods,” likely a text from before the Jin Dynasty, preserving fifty-four formulas for dissolving thirty-four minerals and two non-minerals. The “Baopuzi Jindan Pian” also records many similar elixir formulas. These ancient formulas, combined with records from the Tang and Song Dynasties, allow us to understand the general practices of ancient hydrometallurgical alchemy today.

The methods used in hydrometallurgical alchemy for processing substances approximately included the following: dissolving (sometimes also melting), rinsing (dissolving part of a solid with water), sealing (sealing reactive substances for long-term storage or burial underground), boiling (heating in large amounts of water), simmering (prolonged high-temperature heating with water), nurturing (prolonged low-temperature heating), fermenting (prolonged storage in a moist or carbon dioxide-rich atmosphere), spotting (using a small amount of reagent to transform a large quantity of material), pouring (pouring out the solution to let it cool), soaking (cooling the container externally with cold water), and filtration, recrystallization, etc.

To prepare substances using hydrometallurgical methods, one first needed to prepare the “Hu Chi,” a dissolution tank filled with concentrated vinegar (sometimes substituted with jars or basins). Nitrate and other substances were added to the vinegar. Nitrate, originally called “xiao shi” (saltpeter) in ancient texts, because it could “dissolve seventy-two types of stones,” was very important in Chinese alchemy. In acidic solutions, it provided nitrate ions, functioning similarly to dilute nitric acid, thus enabling the dissolution of many metals and minerals. Ancient Chinese alchemists intentionally added nitrate to acetic acid, which, from a modern chemical perspective, represents a unified application of acid-base reactions and oxidation-reduction reactions, a creative approach in chemical history that remains useful even today.

Regarding the amalgamation of mercury with other metals, ancient alchemists had long observed this phenomenon in their practices. Wei Boyang’s description, “Suddenly obtaining golden essence, it transforms and becomes intimate, turning into white liquid, then solidifying into hardness,” refers precisely to this property of mercury. The amalgams they produced included not only tin amalgam but also those of gold, silver, lead, and other metals. Liu An’s *Huainanzi·Xiushu Xun* mentions that “bright mirrors” required “powdering with dark tin,” where “dark tin” refers to lead amalgam, used in ancient times as a polishing agent for bronze mirrors. Tao Hongjing of the Northern and Southern Dynasties noted: “Mercury can dissolve gold and silver into a paste, which people use for plating.” This indicates that the method of creating gold and silver amalgams was already widely applied in production by that era.

The *Various Divine Elixir Methods* from the Song Dynasty includes the “Method of Transforming Gold into Powder,” which utilized gold amalgam: first, gold amalgam was prepared, then salt was added, and after evaporating the mercury and dissolving the salt, what remained was powdered gold. The *Sixteen Transformations of Sensed Qi Golden Elixir* from the Song Dynasty describes the “Fourteenth Transformation: Purple River Chariot Method”: four taels of cinnabar, four taels of realgar, and two taels of raw mercury were ground into powder, sealed in an alchemical furnace, and heated for sixty days to produce the so-called “Purple River Chariot.” A small amount of this substance could “dry one tael of mercury, turning it yellow.” Some interpret this reaction as follows: the three substances, when heated, might form a reddish-brown solid solution (Purple River Chariot), and adding a small amount of this to mercury could transform it into a yellow solid solution. It is understandable that ancient alchemists studied these reactions of mercury in search of a “divine elixir” capable of “transmuting” mercury into gold. Under the conditions of their time, such aspirations were unattainable, yet their experiments expanded humanity’s understanding of natural phenomena.

Metallic lead and its compounds appeared very early in China. By the Han Dynasty, laborers had already been manufacturing cosmetic powder, known as “hufen” (basic lead carbonate). “Hufen” refers to face powder, not powder from foreigners (as clarified in Liu Xi’s *Shiming* from the Han Dynasty). The *Zhouyi Cantongqi* states: “When hufen is thrown into fire, its color fades and it reverts to lead.” This transformation intrigued alchemists, making it one of their key research subjects. Beyond creating lead amalgam, they also used lead to produce “huangdan” (red lead, or lead tetroxide). The *Baopuzi·Huangbai Chapter* explains: “Lead is inherently white, yet when heated, it turns red as dan (cinnabar); dan is inherently red, yet when whitened, it becomes lead.” This suggests that lead was not only used to make white hufen but also red huangdan, which, when thrown into fire, would similarly “fade and revert to lead.” Later alchemists conducted further research on lead compounds. For instance, the Tang Dynasty’s Qingxuzi, in *Lead and Mercury: The Ultimate Treasure Collection*, describes a “Method of Making Dan,” where lead, sulfur, and saltpeter were melted and treated with vinegar to produce a powder called “huangdan hufen,” likely an impure form of lead acetate.

The *Zhouyi Cantongqi* states: “Gold does not decay; thus, it is the treasure of all things.” Alchemists believed that ingesting “indestructible” substances like gold and silver could render the human body similarly “indestructible.” Hence, they sought not only to consume these materials but also to artificially refine medicinal gold and silver. From Emperor Wu of Han (Liu Che) and Liu An onward, many emperors, nobles, and wealthy families employed alchemists to produce gold for them. While this goal was unattainable at the time, their experiments, built upon the production experiences of laborers, led to numerous innovations in metallurgy. Ge Hong, in *Baopuzi·Huangbai Chapter*, noted that during his era, alchemists possessed the *Divine Scripture of Huangbai Methods*, comprising twenty-five volumes with over a thousand recipes, as well as the *Huangbai Inner Scripture*, all detailing methods for refining “gold” and “silver”—collectively known as “huangbai techniques.” He also mentioned that tin, lead, and mercury could be transformed into “gold” and “silver” using medicinal substances, indicating that Jin Dynasty alchemists had already mastered the creation of various yellow or white alloys from base metals. Tao Hongjing of the Northern and Southern Dynasties, in *Famous Physicians’ Supplementary Records*, stated that realgar “could produce gold when combined with copper,” showing that alchemists of that time knew how to use arsenic-containing minerals to create copper-arsenic alloys. By the Tang and Five Dynasties periods, according to the *Treasure Theory*, fifteen types of counterfeit gold and twelve types of counterfeit silver circulated in the market, all produced through medicinal “transmutation.” This alchemical pursuit flourished in ancient China, persisting even into the Song Dynasty, when Emperor Zhenzong (Zhao Heng, 968–1022) ordered the alchemist Wang Jie to produce “crow-beak gold” from iron, which was then cast into “gold” turtles and plaques for distribution to his close ministers.

Alchemists recognized the “violent toxicity” of substances like sulfur and arsenic trioxide. Before use, they would “subdue” (驯服) these materials by heating, a process called “fuhuo” (伏火, subduing fire), to reduce or eliminate their toxicity. This practice dates back to ancient times and sometimes involved adding flammable substances. Sun Simiao (581–682) of the early Tang Dynasty described a “Method for Subduing Sulfur”: two taels each of sulfur and saltpeter were ground into powder and placed in a stone pot, ignited with three皂角 (carbon-rich) pieces, and after combustion, three catties of charcoal were stirred in until one-third was consumed. During the Yuanhe era (806–820), the alchemist Qingxuzi recorded a “Method for Subduing Alum,” using similar ingredients: two taels each of saltpeter and sulfur, plus three and a half qian of Aristolochia (also carbon-rich). Notably, all “fuhuo” recipes contained carbon, and subduing sulfur required saltpeter, while subduing saltpeter required sulfur. This suggests alchemists intentionally promoted combustion to neutralize toxicity, though the exact chemical purpose remains unclear. However, frequent laboratory fires from “fuhuo” experiments led Tang alchemists to a groundbreaking discovery: sulfur, saltpeter, and carbon could form “gunpowder.” By the late Tang, this formula had transitioned from alchemy to military use, becoming one of China’s Four Great Inventions—black powder.

Another major achievement of pyrometallurgical alchemy was the isolation of elemental arsenic. Ge Hong’s *Baopuzi·Immortal Medicines Chapter* details six methods for processing realgar, the last of which involved heating realgar (As₂S₂) with saltpeter (KNO₃), pig intestine (carbon source), and pine resin. This process first yielded arsenic trioxide (As₂O₃), which was then reduced twice to obtain pure elemental arsenic—a method predating Albertus Magnus’ (c. 1200–1280) arsenic isolation by 900 years.

**Hydrometallurgical Alchemy**
Ancient alchemists sought not only to solidify elixirs but also to dissolve metallic compounds. Their extensive experimentation with aqueous solutions yielded rich empirical knowledge. The *Thirty-Six Water Methods* (possibly pre-Jin) in the *Daoist Canon* preserves 54 recipes for dissolving 34 minerals and 2 non-minerals. Ge Hong’s *Baopuzi·Golden Elixir Chapter* also records similar formulas. These texts, supplemented by Tang-Song records, offer glimpses into ancient hydrometallurgical practices.

Key methods included:
– **Dissolution** (sometimes melting)
– **Leaching** (extracting soluble components)
– **Sealing** (long-term storage underground)
– **Boiling/Simmering** (prolonged heating)
– **Steeping** (exposure to humid/CO₂-rich air)
– **Precipitation** (adding reagents to induce change)
– **Crystallization/Filtration**

Central to these processes was the “Huachi” (华池)—a vinegar-based dissolution vat (often a jar or basin) containing saltpeter. Saltpeter (硝石), pivotal in Chinese alchemy, provided nitrate ions in acidic solutions, mimicking dilute nitric acid to dissolve metals. This intentional combination of vinegar (acid) and saltpeter (oxidizer) represented an innovative unification of acid-base and redox reactions—a landmark in chemical history still relevant today.

Notable hydrometallurgical achievements:
1. **Gold Dissolution**: Ge Hong’s “Golden Fluid Formula” used mercury or hydrogen cyanide (from unripe raspberries in vinegar) to dissolve gold—a remarkable feat given gold’s inertness. This predated modern methods like aqua regia or cyanidation.
2. **Sulfur Solutions**: The *Thirty-Six Water Methods* described creating polysulfide solutions capable of attacking noble metals—an early “universal solvent” concept.
3. **Crystallization Techniques**: The *Yellow Emperor’s Nine-Cauldron Divine Elixir Manual* detailed potassium sulfate purification via differential solubility—another chemical innovation.
4. **Metal Displacement**: Observing iron replacing copper in blue vitriol (CuSO₄) solutions, alchemists documented the earliest known metal displacement reactions, later foundational to wet metallurgy (e.g., cementation copper).

**Alchemical Substances and Tools**
Distinguishing alchemical from medical substances is challenging due to overlapping practices. For instance, the *Shennong Bencaojing* (Han Dynasty), while a medical text, prioritized cinnabar (HgS) as the supreme substance for “immortality,” reflecting alchemical influence. Definitive alchemical contributions include:
– **Mercury and its compounds** (e.g., calomel, Hg₂Cl₂)
– **Sulfides/Arsenides** (realgar, orpiment)
– **Lead/Tin alloys**
– **Early acids/bases** (vinegar, lye)
– **Laboratory apparatus** (sealed vessels, sublimators)

Though some substances (e.g., saltpeter) had prior medical uses, alchemists systematized their chemical applications, laying groundwork for modern chemistry. Their legacy endures not in transmutation but in pioneering experimental methodologies and discovering fundamental chemical processes.

First, it can dissolve in aqua regia, anhydrous selenic acid, and other concentrated acid mixtures that can produce chlorine, bromine, or iodine.

Second, it can dissolve in chlorine water, forming gold trichloride.

Third, it can dissolve in mercury, forming a gold amalgam, which is in liquid form when the gold content does not exceed fifteen percent.

Fourth, under conditions where air (oxygen) is present, it can dissolve in dilute solutions of alkali metal cyanides, forming a dicyanoaurate(I) complex ion [Au(CN)₂⁻].

Looking at the substances used in the gold liquid formula, it is impossible to produce aqua regia, various concentrated acids, or chlorine water. However, mercury and raspberry vinegar extract align with the third and fourth methods mentioned above: if mercury is used, it can dissolve gold; if vinegar and raspberry are used, since immature raspberry fruits contain hydrocyanic acid, the vinegar extract from the Hu Chi would contain cyanide ions and sodium and potassium ions provided by other substances. As long as air is present, gold can slowly dissolve. Given that gold is so difficult to dissolve, the fact that the gold liquid formula contains mercury and hydrocyanic acid (from raspberry), which can dissolve gold, obviously results from extensive experimentation by alchemists. Therefore, despite the complexity of the substances in the formula and the need for further study of some reactions, its ability to dissolve gold is credible. The existence of a method to dissolve gold at such an early time represents a significant achievement in the history of chemistry.

The dissolution of sulfur is also recorded in the “Thirty-six Water Methods,” which includes a method called “Liu Huang Shui,” using substances such as sulfur, chalk, vinegar, and urine (ammonia water). The solution produced should contain calcium polysulfide, a substance that can change the color of metals, form colored precipitates with metal salts, and even corrode precious metals. Alchemists producing such solvents seemed to regard them as a kind of omnipotent “miracle elixir.”

Hydrometallurgical alchemy did not always use vinegar and nitrate; the methods were diverse. The “Huangdi Jiuding Shendan Jing Jue” describes a method for preparing potassium sulfate: hot water is used to dissolve mirabilite and nitrate, the clear mixed solution is heated and evaporated to concentrate it, and then cooled externally with cold water in a small basin. After a night, potassium sulfate crystals slowly form in the solution. This method of using different solubilities to prepare medicines is also a creation in the history of chemistry.

Another discovery in hydrometallurgical alchemy was the displacement of metals in aqueous solutions. Alchemists had long held the theory of mutual “transformation” between metals, and in their quest to create “artificial gold,” they dreamed of finding methods to transform certain base metals into gold and silver. From an early time, they noticed the phenomenon of mutual replacement between metals in solution, believing it to be the “transformation” of metals. The “Huainan Fang Bi Shu” of the Western Han Dynasty already recorded that “when iron comes into contact with copper vitriol, it changes into copper,” where copper vitriol refers to copper sulfate. Ge Hong of the Jin Dynasty further observed that “when copper vitriol is applied to iron, the iron turns red like copper, but the inside does not change.” Tao Hongjing of the Southern and Northern Dynasties expanded the experiments beyond copper vitriol, discovering that chicken dung vitriol (basic copper carbonate or basic copper sulfate) had similar properties to copper vitriol and could be used to “make” (produce) “refined copper.” This indicates that alchemists conducted many experiments and provided the earliest and quite detailed descriptions of metal displacement phenomena. However, due to the limitations of their time, they could not provide correct explanations. This discovery later developed into the origin of the hydrometallurgical method for producing copper from vitriol.

The substances used in alchemy

The ancients had long noticed the amalgamation effect of mercury with other metals in their alchemical practices. Wei Boyang’s description, “Suddenly obtaining golden essence, it transforms and becomes intimate, turning into white liquid, then solidifying into hardness,” refers precisely to this property of mercury. The amalgams they produced included not only tin amalgam but also amalgams of gold, silver, lead, and other metals. Liu An’s *Huainanzi·Xi Wu Xun* mentions that “bright mirrors” required “powdering with dark tin,” where “dark tin” refers to lead amalgam, used in ancient times as a polishing agent for bronze mirrors. Tao Hongjing of the Northern and Southern Dynasties stated: “Mercury can dissolve gold and silver into a paste, which people use for plating.” This indicates that the method of producing gold and silver amalgams was already widely used in production during that period.

The *Various Divine Elixir Methods* from the Song Dynasty includes the “Method of Transforming Gold into Powder,” which utilized gold amalgam to produce gold powder: first, gold amalgam was made, then salt was added, followed by evaporating the mercury and dissolving the salt, leaving behind powdered gold. The *Sixteen Transformations of Sensational Qi Elixir* from the Song Dynasty describes the “Fourteenth Transformation: Purple River Chariot Method”: four taels of cinnabar, four taels of realgar, and two taels of raw mercury were ground into powder, sealed in an alchemical furnace, and heated for sixty days to produce the so-called “Purple River Chariot.” A small amount of this substance could “dry one tael of mercury, turning it yellow.” Some interpret this reaction as follows: the three substances, when heated, might form a reddish-brown solid solution (Purple River Chariot), and adding a small amount of this to mercury could transform it into a yellow solid solution. It is understandable that ancient alchemists studied these reactions of mercury in search of a “divine elixir” capable of “transmuting” mercury into gold. Under the conditions of their time, such aspirations were unattainable, yet their experiments expanded humanity’s understanding of natural phenomena.

Metallic lead and its compounds appeared very early in China. By the Han Dynasty, laborers had already begun producing cosmetic powder, known as “hufen” (basic lead carbonate). “Hufen” refers to face powder, not powder from foreigners (see Liu Xi’s *Shiming* from the Han Dynasty). “When hufen is thrown into fire, its color fades and it reverts to lead” (*Zhouyi Cantongqi*). This transformation caught the attention of alchemists, who made it a key subject of study. Besides using lead to make lead amalgam, they also prepared “huangdan” (red lead, or lead tetroxide). *Baopuzi·Huang Bai Pian* states: “Lead is inherently white, yet when heated, it turns red as dan (cinnabar); dan is inherently red, yet when whitened, it reverts to lead.” This means lead was not only used to produce white hufen but also red huangdan, which, when thrown into fire, would similarly “fade and revert to lead.” Later alchemists conducted further research on lead compounds. For example, Qingxuzi’s *Compendium of Lead and Mercury Alchemy* from the Tang Dynasty includes a “Method for Making Dan,” where lead, sulfur, and saltpeter were melted and treated with vinegar to produce a powder called “huangdan hufen,” likely impure lead acetate.

“Gold does not decay; how then is it the treasure of all things?” (*Zhouyi Cantongqi*). Alchemists believed that ingesting “indestructible” substances like gold, silver, and minerals could make the human body similarly “indestructible.” Thus, they sought not only to consume these substances but also to artificially refine medicinal gold and silver. From Emperor Wu of Han (Liu Che) and Liu An onward, many emperors, nobles, and wealthy families employed alchemists to produce gold for them. While this goal was unattainable at the time, their experiments, based on the production experiences of laborers, led to numerous innovations in metallurgy. Ge Hong’s *Baopuzi·Huang Bai Pian* mentions that during his era, alchemists possessed the *Divine Scripture of Yellow and White Methods*, a 25-volume work containing over a thousand recipes, as well as other texts like *The Central Scripture of Yellow and White*, all detailing methods for refining “gold” and “silver”—collectively known as the “Yellow and White Art.” He also noted that tin, lead, and mercury could be transformed into “gold” and “silver” using medicinal substances, indicating that Jin Dynasty alchemists could already produce various yellow or white alloys from base metals. Tao Hongjing’s *Supplementary Records of Famous Physicians* from the Northern and Southern Dynasties states that realgar “can produce gold when combined with copper,” showing that alchemists of that time knew how to use arsenic-containing minerals to produce copper-arsenic alloys. By the Tang and Five Dynasties periods, according to *The Treatise on Treasures*, the market was flooded with fifteen types of fake gold and twelve types of fake silver, all produced through medicinal “transmutation.” This alchemical activity flourished in ancient China and persisted until the Song Dynasty, when Emperor Zhenzong (Zhao Heng, 968–1022) ordered the alchemist Wang Jie to produce “crow-beak gold” from iron, which was then cast into “golden” turtles and plaques for his ministers.

Alchemists recognized the “violent toxicity” of substances like sulfur and arsenic trioxide. Before use, these materials were “tamed” through calcination to reduce or eliminate their toxicity—a process called “fire subduing.” This method dates back to ancient times and sometimes involved heating alone or adding other flammable substances. Sun Simiao (581–682) of the early Tang Dynasty recorded the “Method for Subduing Sulfur”: two taels each of sulfur and saltpeter were ground into powder and placed in a stone pot, then ignited with three soap pods (containing carbon). After the fire extinguished, three catties of half-burned charcoal were stirred in until one-third of the charcoal was consumed. During the Yuanhe era (806–820), the alchemist Qingxuzi described the “Method for Subduing Alum,” using two taels each of saltpeter and sulfur and three and a half qian of aristolochia (also containing carbon)—almost identical to Sun Simiao’s sulfur-subduing formula. These fire-subduing recipes all contained carbon, and subduing sulfur required saltpeter, while subduing saltpeter required sulfur. This suggests alchemists intentionally made the substances flammable to remove their “violent toxicity.” From a modern chemical perspective, the purpose of this process is unclear. However, frequent fires caused by “fire subduing” led Tang Dynasty alchemists to a crucial discovery: sulfur, saltpeter, and carbon could combine to form “gunpowder.” By the late Tang, this formula had transitioned from alchemists to military strategists, becoming one of China’s Four Great Inventions—black powder.

Another major achievement of pyrometallurgical alchemy was the preparation of elemental arsenic. Ge Hong’s *Baopuzi·Xian Yao Pian* records six methods for processing realgar, the last of which involved heating realgar (As₂S₂) with saltpeter (KNO₃), pig intestine (containing carbon), and pine resin. This process first yielded arsenic trioxide (As₂O₃), which was then reduced twice with carbonaceous pig intestine and pine resin to produce pure elemental arsenic. This marks the world’s earliest method for preparing elemental arsenic, predating the German alchemist Albertus Magnus (c. 1200–1280) by 900 years.

### Hydrometallurgical Alchemy

Ancient alchemists sought not only to refine solid elixirs from mineral drugs but also to dissolve them into liquids. Through long-term experimentation with dissolving minerals, they gained considerable empirical knowledge of complex reactions in aqueous solutions. The *Daoist Canon* includes *Thirty-Six Water Methods*, likely a pre-Jin Dynasty work, preserving 54 recipes for dissolving 34 minerals and two non-minerals. *Baopuzi·Jin Dan Pian* also records many similar formulas. These ancient recipes, combined with Tang and Song Dynasty records, provide a glimpse into hydrometallurgical alchemy.

Methods for processing substances in hydrometallurgical alchemy included:
– **Dissolution** (sometimes melting),
– **Leaching** (extracting part of a solid with water),
– **Sealing** (enclosing reactants for long-term storage or burial),
– **Boiling** (heating in large amounts of water),
– **Simmering** (prolonged high-temperature heating with water),
– **Stewing** (prolonged low-temperature heating),
– **Fermenting** (long-term exposure to moisture or carbon dioxide),
– **Spotting** (using small amounts of reagents to induce large changes),
– **Pouring** (cooling by decanting solutions),
– **Quenching** (cooling containers externally with cold water),
as well as filtration and recrystallization.

To prepare substances hydrometallurgically, a “hua chi” (dissolution vat) was first prepared—a container filled with strong vinegar (sometimes replaced by jars or basins), into which saltpeter and other substances were added. Saltpeter, originally called “xiao shi” in ancient texts for its ability to “dissolve seventy-two stones,” was crucial in Chinese alchemy. In acidic solutions, it provided nitrate ions, functioning similarly to dilute nitric acid, enabling the dissolution of many metals and minerals. Ancient alchemists deliberately added saltpeter to acetic acid—a method that, from a modern chemical perspective, unified acid-base and redox reactions, representing an innovative approach that remains useful today.

Some dissolution reactions in the hua chi were remarkably complex, showcasing sophisticated chemical methods long before modern chemistry. Examples include:

1. **Dissolution of Gold**: *Baopuzi·Jin Dan Pian* describes the “Gold-Dissolving Solution,” which used vinegar, saltpeter, halite, and “Xuanming Longgao” (possibly mercury or vinegar and raspberry extract). According to the text, sealing gold with these substances for 100 days would slowly dissolve it into “water.” Modern chemistry confirms gold’s inertness, with only four known dissolution methods:
– Aqua regia or other halogen-producing acids,
– Chlorine water (forming gold trichloride),
– Mercury (forming gold amalgam, liquid at ≤15% gold),
– Alkali cyanide solutions with oxygen (forming dicyanoaurate(I)).
The “Gold-Dissolving Solution” likely relied on mercury or cyanide from unripe raspberries (which contain hydrogen cyanide), making it a groundbreaking achievement.

2. **Dissolution of Sulfur**: *Thirty-Six Water Methods* includes “Sulfur Water,” made from sulfur, chalk, vinegar, and urine (ammonia). This solution probably contained calcium polysulfide, capable of altering metal colors and forming colored precipitates—possibly regarded as a universal “divine elixir.”

Hydrometallurgical methods varied beyond vinegar and saltpeter. *The Nine Cauldrons Divine Elixir Scripture* describes preparing potassium sulfate by dissolving and evaporating mixed solutions of saltpeter and mirabilite, then crystallizing the product—an early example of solubility-based separation.

Another discovery was metal displacement in solution. Alchemists, seeking to “transmute” base metals into gold, observed this phenomenon as early as the Western Han (*Huainanzi·Bi Shu*: “Zengqing [copper sulfate] turns iron into copper”). Ge Hong noted iron surfaces turning copper-colored when coated with copper sulfate, while Tao Hongjing extended this to other copper compounds like “chicken dung vitriol” (basic copper carbonate/sulfate). These observations laid the groundwork for wet metallurgy (e.g., the cementation method for copper), though misinterpreted as “transmutation.”

### Alchemical Substances and Tools

Alchemy contributed to chemistry by providing substances and apparatus, though distinguishing alchemical from medical use is challenging—many alchemists were also physicians, and vice versa. For instance, the *Shennong Bencaojing* (Eastern Han), primarily a medical text, lists cinnabar as the top-grade drug and includes over 40 mineral substances used in alchemy, ranked by their supposed ability to “prolong life, ascend to heaven, and achieve immortality”—clearly reflecting alchemical ideology. Similarly, alchemists’ medical works like Ge Hong’s *Emergency Prescriptions*, Tao Hongjing’s *Supplementary Records*, and Sun Simiao’s *Supplement to the Thousand Gold Formulas* blur the lines. Thus, while many substances originated in alchemy, some may have medical roots. Below is a non-exhaustive list of alchemical materials (excluding those definitively medical in origin):

**Metals and Minerals**:
– Gold, silver, copper, iron, tin, lead, mercury,
– Cinnabar (HgS), realgar (As₂S₂), orpiment (As₂S₃),
– Sulfur, saltpeter, mirabilite (Na₂SO₄·10H₂O),
– Malachite, azurite, chalcanthite (CuSO₄·5H₂O),
– Litharge (PbO), minium (Pb₃O₄), cerussite (PbCO₃).

**Organic Substances**:
– Vinegar, urine, plant extracts (e.g., raspberry, aristolochia),
– Pine resin, animal tissues (e.g., pig intestine).

**Apparatus**:
– Crucibles, furnaces, stills,
– Sealed vessels (for long-term reactions),
– Filters, crystallization dishes.

Though not all were alchemical inventions, these materials and tools formed the empirical foundation for later chemical science.

Regarding medicinal substances, Yuan Hanqing, a historian of chemical history (1905–1994), once compiled an incomplete list based on alchemical texts, including both inorganic and organic substances, totaling approximately sixty types. The list, slightly revised, is presented below:

### Tools and Equipment Used in Alchemy

Regarding tools and equipment, alchemical texts mention over ten types, including the alchemical furnace, alchemical vessel, water basin, pomegranate-shaped flask, distillation apparatus, reaction chamber, grinding tools, silk sieve, horsehair sieve, etc.

The **alchemical furnace**, also called the alchemical stove, was described in Wu Wu’s *Essentials of the Alchemical Chamber* (1163 AD) as the “Ji Ji Furnace” and “Wei Ji Furnace.” Inside the furnace was the **alchemical vessel**, also known as the “divine chamber,” “container,” or “alchemical box.” These vessels varied in shape—some resembled gourds, others crucibles—and were made of metal (gold, silver, copper) or ceramics. The *Great Essentials of the Golden Elixir* mentions a “suspended vessel” with three layers, hung within the furnace without touching the ground. The *Essential Teachings of the Golden Flower Alchemy* describes a silver “water basin” placed atop the vessel for cooling. The *Key Principles of Refining the Great Elixir* mentions a “water-fire vessel,” possibly featuring a water-holding section. These tools were central to alchemy, allowing substances to be heated, melted, reacted, or sublimated.

Beyond the alchemical vessel, alchemists also used specialized **distillation apparatus** for extracting mercury from cinnabar. The *Essential Teachings of the Golden Flower Alchemy* describes a simple two-part device: an upper flask called the “pomegranate vessel” and a lower bucket-shaped component called the “distillation pot.” When heated, mercury vapor condensed into liquid in the cooling water below. Wu Wu’s *Essentials of the Alchemical Chamber* depicts a more complex distillation setup, with a furnace below and a sealed container for cinnabar above, connected to a condenser. This design was remarkably advanced for its time and predates similar devices in the Arab world. Western historians often credit Arabs with inventing distillation, but Chinese alchemists had long mastered such techniques.

### The Relationship Between Chinese and Western Alchemy

Modern chemistry developed from medieval European alchemy, which in turn originated from Arab alchemy—a well-established fact in the history of science. However, until the 1930s, few recognized the deep connections between 8th-century Arab alchemy and Chinese alchemy.

Striking similarities exist between the two traditions: Chinese alchemists sought a “divine elixir” capable of granting immortality and transmuting base metals into gold, while Arab alchemists pursued a similar universal remedy called the “elixir” or “philosopher’s stone.” Both attempted to create gold from mercury and sulfur. The *Huainanzi*’s theories on metal transformation underground find parallels in the writings of Arab alchemist Jabir ibn Hayyan. Given the late emergence of Arab alchemy and existing cultural exchanges, these resemblances strongly suggest Chinese influence.

Notably, Chinese alchemy employed **saltpeter** and **borax**, unknown to ancient Greece and Egypt. Arabs and Persians not only used these substances but even called saltpeter “Chinese snow” in Arabic and “Chinese salt” in Persian. Arab and Persian alchemists also listed “Chinese metal” or “Chinese copper” among their seven metals—clear evidence of Chinese alchemy’s transmission to Central Asia and Egypt. The Arabic term for alchemy, *al-kimiya*, may derive from the ancient Chinese pronunciation of “golden liquid” (*kim-ya*), reflecting extensive trade links during the Tang and Song dynasties, particularly with the Arab Empire via ports like Quanzhou.

Yet, early 20th-century Western scholars remained oblivious to these facts, erroneously attributing alchemy’s origins solely to Greece and Egypt. Some even claimed Chinese alchemy was imported via Arabs. Only in the 1930s did rigorous research by Eastern and Western scholars clarify the truth, affirming China’s profound contributions. As historian Joseph Needham (1900–1995) noted, “One of the most important roots (if not the very most important) of chemistry as a whole is to be found in China.” Indeed, the Chinese people, like in other scientific fields, made monumental contributions to chemistry.

Certainly, this list is not yet complete, because not only are plant- and animal-based medicines excluded, but even from the perspective of mineral medicines alone, there should be more than these sixty types.

Tools and Equipment Used in Alchemy

Regarding tools and equipment, the alchemical literature mentions about a dozen types, including alchemical furnaces, crucibles, water vessels, pomegranate jars, Ganwozi (condenser vessels), mercury extractors, Hua Chi (reaction pools), grinding devices, silk sieves, Ma Wei Luo (fine silk sieves), etc.

The alchemical furnace is also called the Dan Zao (alchemical stove). The Southern Song Dynasty text “Dan Fang Xu Zhi” (compiled in 1163) mentions the “Ji Ji Lu” (boiling furnace) and the “Wei Ji Lu” (non-boiling furnace). The reaction chamber placed inside the alchemical furnace is called the Dan Ding, also known as “Shen Shi” (spirit chamber), “Kui” (urn), or “Dan He” (alchemical box). Some resembled gourds, others crucibles, some were made of metal (gold, silver, copper), and others were made of porcelain. The “Jin Dan Da Yao” (Essentials of the Golden Elixir) describes a “Xuan Tai Ding” (hanging fetus crucible), which has three layers and is suspended within the stove without touching the ground. The “Jin Hua Chong Bi Dan Jing Yao Zhi” (Essential Points of the Golden Flower Alchemical Classic) states that a silver-made “Shui Hai” (water vessel) was placed above the Shen Shi for cooling. The “Xiu Lian Da Dan Yao Zhi” (Essentials of Alchemical Practice) describes another type called the “Shui Huo Ding” (water-fire crucible), which may have had a section for holding water. In short, these were the main tools used in alchemy. They could be placed inside the furnace for heating, allowing the substances to melt and react, or to sublime.

In addition to the Dan Ding, alchemists also had a specialized distillation apparatus for extracting mercury from cinnabar, known as the “mercury extractor.” The “Jin Hua Chong Bi Dan Jing Yao Zhi” describes a simple version consisting of two parts: an upper part shaped like a round-bottomed flask called the “Pomegranate Jar,” and a lower bucket-shaped part called the “Gan Wozi.” During operation, heat was applied so that mercury vapor generated in the jar would condense into liquid mercury in the cold water of the Gan Wozi. The Southern Song alchemist Wu Wu’s “Dan Fang Xu Zhi” also includes an illustration of a more complex distillation apparatus. Although the material, size, and usage are not explained, the illustration clearly shows a furnace at the bottom for heating, a sealed upper container holding substances such as cinnabar, and a pipe leading from the container to a nearby condensation jar where the mercury vapor could collect. Such distillation equipment, even by today’s standards, is quite advanced. It was certainly the result of gradual improvements made through long-term alchemical practice, and its development must have occurred before Wu Wu’s time.

Western historians of science have long believed that distillation equipment was invented by the Arabs. In fact, ancient Chinese alchemists had already developed the tradition of manufacturing such devices.

The Relationship Between Chinese and Western Alchemy

Modern chemistry developed on the basis of medieval European alchemy, which itself originated from Arabic alchemy. This is a widely accepted fact in the history of science. However, until the 1930s, people were unaware that Arabic alchemy, which emerged in the 8th century, had close connections with Chinese alchemy.

There are many similarities between Chinese alchemy and Arabic alchemy: Chinese alchemists pursued an “elixir” that could both grant “immortality” and “transmute base metals into gold,” just as Arabic alchemists sought this universal elixir, which they called “Nariksa” or the “Philosopher’s Stone.” Chinese alchemists attempted to transform cinnabar into gold using certain methods, while Arabic alchemists also sought to create gold using sulfur and mercury. Ancient Chinese texts such as the “Huainanzi·Zhui Xing Xun” (The Fall of Form) contain theories about the growth and transformation of metals underground, and similar ideas were expressed by the Arabic alchemist Ibn Hayyan. Since Arabic alchemy appeared much later and there was already cultural exchange between China and the Arab world, these similarities should be viewed as evidence of the transmission of Chinese alchemy to the West.

More notably, Chinese alchemy employed substances such as saltpeter and borax, which were unknown in ancient Greece and Egypt. The Arabs and Persians also used these substances, and saltpeter was called “Chinese snow” in Arabic and Egyptian, and “Chinese salt” in Persian. Furthermore, Arab and Persian alchemists included a “Chinese metal” or “Chinese copper” among the seven metals, which can be considered clear evidence of the transmission of Chinese alchemy to Central Asia and Egypt. Moreover, the Arabic term for alchemy is “al-kimiya,” and some suggest that “kimiya” is a transliteration of the Chinese term “jin ye” (golden liquid). This is quite plausible, as during the Tang and Song dynasties, China maintained frequent contact with Central Asia, especially during the Song dynasty when maritime trade with the Arab Empire (known as Dashi in Chinese) was highly developed. Quanzhou, Fujian, was one of the major trading ports, and even today, the Quanzhou dialect still pronounces “jin ye” as “kim-ya.”

However, in the early 20th century, Western scholars were completely unaware of these facts. They not only regarded ancient Greece and Egypt as the sole origins of alchemy, but some even insisted that Chinese alchemy was a foreign import introduced through the Arabs from Greece. It was not until the 1930s, when scholars from both China and the West conducted serious research, that the truth gradually emerged, confirming the long and rich history of Chinese alchemy. British historian of science Joseph Needham (1900–) stated: “One of (if not the most important) the most significant roots of modern chemistry is genuinely and directly transmitted from China.” This statement is accurate. The Chinese nation has made great contributions to the development of chemistry, just as it has in other fields of science and technology.

Liter
1000 cubic centimeters or 1.06 U.S. quarts.

Lowell, Percival (1855–1916)
An American astronomer who founded the Lowell Observatory in Arizona in 1894. His research on Mars led him to believe that the linear markings on Mars, described by Schiaparelli, were evidence of canals and suggested the presence of intelligent life. His successor discovered Pluto.

Mensa
A flat-topped mountain.

Metal
In astrophysics, this term refers to any element other than hydrogen and helium. A famous saying is: “The universe is made of hydrogen, helium, and trace amounts of metals.” (Note: this differs from the usual chemical definition.)

Meteor
(Also known as a “shooting star” or “falling star”) The luminous trail produced when a meteoroid or small ice particle enters Earth’s atmosphere and heats up due to friction. Larger meteors are called fireballs or bolides.

An American astronomer who discovered Jupiter’s moons Lysithea, Carme, Ananke, and Sinope. He also made significant contributions to the study of sunspots.

Nuclear Fusion
A nuclear process in which several atomic nuclei combine to form a larger nucleus, with a mass slightly less than the sum of the original nuclei. The difference in mass is converted into a tremendous amount of energy according to Einstein’s famous equation E=mc². This is the principle behind the Sun’s energy and most of the energy received on Earth.

Old
A planetary surface that has changed little since acquiring many distinct impact craters. (Opposite of young.)

Oort, Jan Hendrik (1900–1992)
A Dutch astronomer who made outstanding contributions to the study of the structure and rotation of the Milky Way. As a side interest, he conducted notable research on comets. His studies led to the widely accepted theory that the Sun is surrounded by a distant cloud of cometary bodies, now known as the Oort Cloud. Some of these occasionally enter the inner solar system, becoming the comets we observe.

Opposition
When a planet is on the opposite side of Earth from the Sun, it is said to be in “opposition.” This is usually also the planet’s closest approach to Earth and the best time for observation.

A theory of motion more precise than Newtonian mechanics, especially in strong gravitational fields or at speeds approaching the speed of light. All experimental results agree with the precise predictions of relativity. (Interestingly, Einstein received the Nobel Prize in 1921 not for relativity, but for his work on the photoelectric effect and “theoretical physics research” in 1905.)

Resolution
The amount of visible detail in an image. Low resolution shows only large features, while high resolution reveals many small details.

Rift Valley
An elongated depression between fault blocks in a planetary crust, with multiple nearly parallel faults.

Rima
A crack or fissure.

Roche Limit
The minimum distance at which a satellite with a fluid core can orbit its primary body without being torn apart by tidal forces. Solid bodies can exist within the Roche limit as long as the tidal forces do not exceed the structural strength of the solid. The formula for calculating the Roche limit is:
RL = 2.456 × R × (ρ’/ρ)^(1/3)
Where ρ’ is the planet’s density, ρ is the satellite’s density, and R is the planet’s radius.

Rupes
A cliff.

Scarp
A cliff formed by faulting or erosion.

Schiaparelli, Giovanni Virginio (1835–1910)
An Italian astronomer who first observed “canals” on Mars in 1877. He believed the intersecting straight lines he observed formed complex patterns. He called them “canali,” meaning “channels.” However, this Italian word was mistranslated into English as “canals,” implying artificial construction. Combined with the straightness of the lines, this sparked widespread speculation and interest in intelligent life on Mars. Astronomers, especially Percival Lowell, seriously considered this possibility and conducted even more detailed studies than Schiaparelli.

scopulus
An irregular, leaf-like cliff.

semimajor axis
The semimajor axis is half the length of the major axis of an ellipse (the orbital path of a planet), where the major axis is the line segment passing through the foci and intersecting the ellipse. The length of the semimajor axis corresponds to the average distance of a planet from its central star. The perihelion and aphelion can be calculated using the semimajor axis and the orbital eccentricity: R_perihelion = a(1 – e), R_aphelion = a(1 + e).

Shakespeare, William 1564–1616
An English playwright and poet who wrote several excellent comedies.

299,792,458 meters per second (186,000 miles per second). According to Einstein’s theory of relativity, no object can travel faster than light, although Scotty and Geordi might know better.

spicules
Grass-like patterns visible in the Sun’s atmosphere.

stellar classification
A system for classifying stars based on their spectra, consisting of a letter and a number, which roughly reflect their surface temperatures. The categories are: O, B, A, F, G, K, and M (a mnemonic: “Oh, Be A Fine Girl, Kiss Me”). O-type stars are the hottest, while M-type are the coolest. The numbers further subdivide each category. Since the relationship between spectral features and temperature was not fully understood at the time of classification, this system only roughly reflects temperature. O and B stars are rare but extremely bright, while M stars are numerous but dim. The Sun is classified as G2.

sublime (or sublimate)
The process by which a solid changes directly into a gas, skipping the liquid phase.

sulcus
Small, parallel grooves and ridges.

sunspot
A darker region on the Sun’s photosphere; sunspots are manifestations of concentrated magnetic fields and are typically found in pairs—one with a north (N) pole and the other a south (S) pole. They appear darker because their temperature is lower than that of the surrounding photosphere.

superior planets
The planets Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto are called superior planets because their orbits lie farther from the Sun than Earth’s.

synchronous orbit radius
A specific orbital radius at which a satellite’s orbital period matches the rotational period of the planet. A synchronous satellite with zero orbital inclination (aligned with the planet’s equator) appears stationary to an observer on the ground. This type of orbit is widely used for communication satellites.

synchronous rotation
When a satellite’s rotational period matches its orbital period around its primary body, causing it to always present the same face to the primary (e.g., the Moon). This also means one hemisphere (the leading hemisphere) always faces the direction of motion, while the other (the trailing hemisphere) faces the opposite direction. Most satellites in the solar system rotate synchronously.

T
tectonic
Destructive forces acting on a planet’s outer layer.

terminator
The dividing line between the illuminated and unilluminated portions of a planetary or satellite disk.

An American astronomer who discovered Pluto.

Trekkie
(Also known as ‘Trekker’) A fan of the science fiction television series Star Trek.

Trojan
An object that orbits around a larger body at its Lagrange points. The name originates from the generalization of the names of the largest asteroids at Jupiter’s Lagrange points: 588 Achilles, 624 Hektor, and 911 Agamemnon. Saturn’s moons Telesto, Calypso, and Helene are sometimes referred to as Trojans.

U

As a noun, a substance that exists as a gas at normal temperatures. In astronomy, volatiles include hydrogen, helium, water, ammonia, carbon dioxide, and methane.

W
white dwarf
A white star with a high surface temperature but low intrinsic brightness, having a mass roughly equivalent to the Sun but much greater density. (The density of a white dwarf is approximately two tons per cubic centimeter.)

Y
young
When describing a planetary surface as “young,” it means that many visible features are relatively recent, while older features have been largely erased (e.g., by erosion or lava flows). Young surfaces have fewer craters and are typically more diverse and complex. In contrast, an ‘old’ surface has undergone little geological change. Earth and Io have “young” surfaces, while Mercury and Callisto have “old” surfaces.

Z
zodiacal light
A faint glow of reddish light caused by interplanetary dust scattering sunlight along the ecliptic plane.
