The chemical name of this compound is based on the ancient method of "Tiangong Kaiwu", and should be based on the traditional naming rules. Ancient chemical names are often based on their properties, sources, uses, etc., which are concise and comprehensive, and passed down with clear meanings.
Looking at this compound, if its color is red, and it is obtained by the method of fire refining, or it is called "red refining stone essence". Gai "red" shows its color, "refining" shows how it is obtained, and "stone essence" shows that it is derived from stone and is an essence.
Another example is, if its texture is hard, and it is mostly used to make blades, or it is called "hard blade treasure sand". " Jian "speaks of its texture," blade "shows its use, and" treasure sand "shows its preciousness, and its shape is like sand grains.
If it has the ability to replenish benefits in the path of medicinal stones, and it is collected in the spiritual land of deep mountains, or the name" Lingyue replenishing pills "." Lingyue "refers to its origin as a beautiful mountain," replenishing "shows its medicinal properties, and" Dan "has the meaning of precious pills.
The ancient chemical naming, although not the exact science of today, is rich in the wisdom of humanities and experience. It is best to use the image to express the meaning and use the name to make those who hear the name know its nature. At that time, the knowledge and craftsmanship were already the best. Therefore, in order to confirm the name of this compound, it is necessary to carefully examine its various characteristics and obtain an appropriate name according to ancient principles.

This object has all kinds of physical characteristics. Its quality is firm and tough, just like the solidification of gold and stone, it is not easy to break, and external force is added, and it can be resisted by many. Looking at its shape, it may be regular and round, or square and neat, with natural craftsmanship. Touch it, I feel that it is moderately warm and cool, not hot in summer, not cold in winter, and it seems to be able to adjust its temperature to suit people.
Its density is quite unique, and it sinks when it enters the water, but it is not as rapid as the sinking of iron and stone. It slowly descends, as if it is in harmony with water and does not refuse. Its sound is also wonderful, and when it hits it, the sound is longer and longer, and it echoes in the air, like the beginning of fairy music, and the aftertaste is endless.
And its conductivity of electricity and heat is different from that of ordinary things. Electricity cannot travel freely in it, and if it encounters obstacles; when heat is transferred, it is also slow and orderly, without sudden cold and sudden heat. This material is stable, can be settled in all kinds of environments, and does not change color with the environment. It can be said to be resolute and unyielding.
And it also has a unique response to light. Light shines on it, or it reflects radiance, and the light is soft and not dazzling; or it refracts and transmits light, and the light it penetrates is colorful, like the wonderful colors of heaven and earth. This is a summary of its physical characteristics. Each item has its own magic, which needs to be carefully investigated by the world.

Mercury is soft and good at flowing, liquid at room temperature, silver-white and metallic. Its chemical properties are unique and have many wonderful signs.
Mercury has moderate activity and is in a specific position in the order of metal activity. When encountering strong oxidants, such as aqua regia, it can respond to it. In aqua regia, a strong acid composed of nitric acid and hydrochloric acid in a specific ratio can dissolve mercury to produce corresponding mercury salts, which is a sign of mercury's reductivity. Mercury loses electrons and increases in valence.
Mercury is also volatile. Under normal temperature and pressure, it slowly disperses in the air. This characteristic makes it easy to form mercury vapor. Mercury vapor is toxic and can enter the human body and damage the viscera, especially the nervous system. Its volatility is closely related to temperature. When the temperature rises, the volatilization increases rapidly.
When mercury meets sulphur powder, it synthesizes at room temperature to form mercury sulfide. This reaction is fast and stable, and the nature of mercury sulfide is stable. It is red in color and is often called cinnabar. The ancients often used this method to remove mercury in order to protect the environment and personal safety.
Mercury oxides also have characteristics. Mercury and oxygen can be obtained by heat decomposition. This reversible change shows the difference in the stability of mercury compounds under different conditions.
Mercury is also used in organic synthesis and other fields. With its specialization, it can promote certain reactions, change the reaction path, increase the reaction rate and yield. However, due to mercury toxicity, its application is gradually limited, and more alternative methods are sought to take into account the needs of the chemical industry and environmental safety.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, and its main uses cover many aspects.
The first to introduce recording and inheritance technology. The book details a wide range of production technologies in agriculture and handicrafts, from grain planting, silk weaving to metal smelting, ceramics firing, etc. For example, for rice and wheat cultivation, from the sowing season, field management to harvesting skills are explained; ore selection, blast equipment and forging process during iron smelting are also recorded one by one, so that the advanced technology at that time can be preserved, and future generations can study and inherit it accordingly.
Furthermore, in order to promote production development. Its description of the optimization and innovation of production processes in various industries provides reference for practitioners. For example, in the textile industry, the records on the structure and operation methods of jacquard machines help craftsmen improve production efficiency and fabric quality; the introduction of salt drying and salt boiling methods in the salt making process is conducive to the improvement of salt production and the progress of related industries.
In addition, it is conducive to knowledge dissemination and exchange. At that time, traffic information was inconvenient, and this book would integrate the decentralized technical knowledge system. Literati and scholars can use this to understand different industries and promote cross-disciplinary knowledge exchange; craftsmen from all over the world can also learn from the book to promote technological integration and development.
At the same time, it is of great significance to scientific research. Provide first-hand information for future generations to study ancient science and technology, economy and social development. Modern scholars can explore the production level, process characteristics and social and economic conditions at that time from the book, and help to deeply understand the ancient scientific and technological civilization In short, "Tiangong Kaiwu" is a comprehensive and systematic record, which plays an extraordinary role in technological inheritance, production promotion, knowledge exchange and scientific research, and deserves the reputation of "the encyclopedia of Chinese crafts in the 17th century".

There are many ways to synthesize something, and today I will briefly describe it as follows.
First, it is made by the law of nature. Between heaven and earth, everything is born according to the principles of nature. If the growth of grass and trees is moistened by the rain and dew of heaven and earth, it will grow naturally in the order of four times. This is the creation of heaven and earth, not due to the strength of human power. For example, some ores, deep in the earth's crust, over a long period of time, are gradually synthesized into specific shapes and textures by natural forces such as ground temperature and pressure.
Second, the method of human ingenuity. With their exquisite skills, craftsmen can transform all kinds of materials into what they need. Such as the work of casting swords, choose good iron, through thousands of tempering, quenching and cold forging, adjusting its hardness and toughness, and finally become a sharp sword. And if you fire ceramics, collect clay, make billets and shape them, and calcine them in a kiln at an appropriate temperature, you will get exquisite pottery. In the meantime, the craftsman examines the properties of the materials and the suitability of the heat, all of which require exquisite control.
Third, the method of matching medicinal stones. Doctors combine various medicinal stones, and according to the different diseases, the monarch and minister are in charge of them, and they are skillfully matched. Looking at the herbs contained in Materia Medica, many herbs have their own flavor and return to the meridians. Whether cold or hot, or nourishing or diarrhea, used in combination, can cure various diseases. Such as the cure for typhoid fever, ephedra, cinnamon, etc. are combined. According to the severity of the disease and the strength of the patient's constitution, the dosage is determined, so that the medicinal power can be combined to remove evil and correct.
Fourth, by the method of combination. In the alchemy room, the alchemist wanted to change gold and stone, and used various minerals, such as mercury, lead, sulfur, etc., through special methods to make them synthesize. Although the alchemist's pursuit of longevity is absurd, the method of synthesis he tried is also the germ of later chemistry. If mercury and sulfur are combined, mercury sulfide can be obtained, which is also an attempt to synthesize.
To sum up, the synthesis of things, the law of nature depends on the creation of heaven and earth, the law of manpower depends on the ingenuity of craftsmen, the compatibility of medicinal stones is the art of physicians, and the law of combination contains the power of alchemists. All methods have their own reasons, and they can be used in different domains to become all kinds of utensils, medicinal bait, etc. in the world to meet the needs of people.
