The chemical structure of this product is a crucial question. However, I don't know why this product is, and it is difficult to describe it in ancient Chinese.
If it is a common chemical substance, the analysis of its chemical structure is often related to the arrangement of atoms and the formation of chemical bonds. For organic compounds, carbon atoms are mostly the basis of their structure, and are connected to atoms such as hydrogen, oxygen, and nitrogen by covalent bonds to form different functional groups, so they have different chemical and physical properties.
If it is an inorganic compound, or if it is arranged by metal and non-metal atoms in a certain proportion and rule, the structure is maintained by ionic bonds, covalent bonds, etc. Such as sodium chloride, sodium ions and chloride ions are arranged interactively to form a lattice structure.
However, I don't know the category and characteristics of this product. It is difficult to explain its chemical structure in quaint and elegant words like "Tiangong Kaiwu". If you want to be clear, you need more information about this product, such as its source, properties, reaction characteristics, etc., before you can describe its chemical structure in detail according to scientific principles and classical methods.

The physical properties of the husband's products involve a wide range, and this is for you to state in detail.
First, the form is also. Things have three states: solid, liquid, and gas. Such as gold and stone, which are often solid, their shape is fixed, and the quality is also stable. They can be used for utensils and bear load. The genera of water and oil are liquids, which are shaped with the device and have good fluidity. They can pass through ditches and are also used for irrigation and lubrication. As for air and steam, they are gaseous, diffuse and invisible, and fill all directions. Although difficult to touch, they are related to breathing and power needs.
Second, density is important. This is the mass of matter per unit volume. Gold has a high density, so it sinks in water and has a heavy texture. It can be used as currency and jewelry because it is precious and stable. The density of wood is small, and it often floats in water, making it easy to make boats and boats, so that it can travel in rivers, lakes and seas. If oil and water are compared, the density of oil is less than that of water. When the two meet, the oil will float on the water. This characteristic is very useful in separation and identification.
Third, it is related to the hardness of the product. Steel has high hardness, and can be used to cast swords and bridges to resist the impact and extrusion of external forces. The hardness of clay is slightly lower. After being fired into pottery, it can be used as utensils. However, it needs to be handled with care to prevent damage. The hardness of jade is moderate, warm and firm, and it can be used for beauty decoration after carving.
Fourth, thermal conductivity cannot be ignored. Metals are mostly good heat conductors, such as copper and aluminum, which are often used in cookware to transfer heat quickly and make food ripen quickly. Wood and ceramics have weak thermal conductivity and can be used as handles to prevent hot hands.
Fifth, electrical conductivity is different. Copper, silver and other metals have excellent electrical conductivity and are the key to circuits. They can make current flow smoothly and are used in electrical appliances and communications. Rubber and ceramics, on the other hand, have poor electrical conductivity and can be used as insulating materials to ensure the safety of electricity.
The physical properties, morphology, density, hardness, thermal conductivity, and electrical conductivity of products are essential for production, life, and technology. They can be used for the benefit of people.

The chemical properties of a product are related to the characteristics of its inner essence, which are revealed by chemical reactions and affect its behavior in various situations. Although Guanfu's "Tiangong Kaiwu" has been written for a long time, there are many insights into the chemical properties of things, which can be used for our generation to understand this question.
The chemical properties of all things are first related to their chemical composition. In the book, it is recorded that the genera of hardware, gold, silver, copper, iron, and tin, have their own qualities. The so-called "gold beauty, its value is 16,000 times that of black iron, but the kettle, jackpot, and axe are not effective for daily use, that is, gold, straight high and without people's ears". This is to say that although gold is precious, its chemical properties are stable. In the production of daily utensils, it is not as easy as iron to react with other things to form usable utensils. Iron, on the other hand, is easy to combine with oxygen and water in the air and rust. This is an important chemical property of iron. The book also contains the method of smelting iron. By burning charcoal, iron oxides are reduced to iron. This chemical reaction shows that the chemical properties of iron can be changed due to external forces.
Furthermore, the chemical properties of a substance are related to its reactivity with others. Such as sulfur and saltpeter, these two are essential in the production of gunpowder. Sulfur is flammable, saltpeter supports combustion, and the two are mixed with charcoal powder in a certain proportion. In case of fire, it will explode. This violent chemical reaction shows its lively chemical properties. The article "Gunpowder" in "Tiangong Kaiwu" details the ratio and production of gunpowder, which shows that the ancients mastered the chemical properties of sulfur and saltpeter. For example, when ceramics are fired, clay reacts chemically with gases in the kiln at high temperature, causing its texture and color to change. The chemical changes of various components in clay at high temperature determine the quality of ceramics, which is also a manifestation of chemical properties.
The chemical properties of some things are related to their stability. Oils and fats are easy to rancid after being left for a long time, which is easy to oxidize due to their chemical properties. Salt, on the other hand, is relatively stable in chemical properties and can be stored for a long time. Although its chemical properties are not detailed in the book, it can be seen from daily use that it is not easy to change due to ordinary environmental factors.
In short, the chemical properties of products are diverse, either related to composition, or related to reactivity and stability. Although Tiangong Kaiwu is not described in detail in today's chemical terms, many examples show that the ancient people have a deep understanding and utilization of the chemical properties of things.

The main use of a product is related to the value and significance of its existence. From the perspective of "Tiangong Kaiwu", everything has its own specific function.
All kinds of products made by Fu Baigong have different uses. Such as agricultural equipment, it is to help farmers cultivate. Leiyu and the like, breaking the soil and turning the ground, making the soil loose, which is conducive to seed sowing and crop growth, and is related to the foundation of people's food. Farming relies on this equipment to get twice the result with half the effort, and the grain can be harvested abundantly, so that the people will not be discouraged from hunger.
If the loom used in textiles is used to weave silk, linen and other raw materials into cloth. The cloth can cover the people's bodies to keep out the cold, and is also an important commodity for commercial circulation. Exquisite cloth and silk can also become the material for the fine clothes of officials and nobles, showing their status. From the silk reeling of silkworm cocoons to the interweaving of warp and weft into cloth, the loom is indispensable.
Another example is the casting tool, which can melt and cast metal to make all kinds of tools and weapons. Iron knives can be used for felling and cutting, and are indispensable in carpentry, cooking, etc. Weapons are related to national defense and security, defending the home and the country, and resisting foreign invaders.
Building materials also have their great uses. Brick and stone are used to build walls and houses, providing people with a safe place to live. The material of the pillars supports the structure of the house, making the residence strong and durable.
And ceramic products, either for eating utensils, clean and practical; or for ornamental furnishings, add elegance to life. They play an important role in daily life and cultural aesthetics.
All kinds of products, widely used, or related to people's livelihood, or related to national defense, or related to cultural aesthetics. All are born to meet the various needs of people, and are of great significance to social stability, economic development, and cultural inheritance.

In every method of making things, the first priority is to choose materials. Good materials are strong and beautiful, and poor materials are brittle and ugly. As Tiangong Kaiwu says: "Silk, hemp, fur, and brown in the world all have qualities, so that the special face and color can be used. It is said that those who create things do not work hard, I do not believe it." When selecting materials, they must be carefully selected, and their texture, color, and texture must be carefully selected, so that they fit into the made things.
The second is design. The heart has a picture, and then it can be done in the hand. The essence of design, when it is suitable for use, is also expensive and ingenious. The use of utensils, whether for food, for daily living, or for labor, must be based on satisfying their use. However, it can only be applied, but it is not enough to be praised. It must be applied, and it must be seen in exquisite thinking, in order to be fascinating.
Furthermore, the skills of workmanship are of paramount importance. The craftsman handles the utensils, moves the heart with his hands, and guides the skills with his heart. All genus of cutting, cutting, carving, carving, casting, and dyeing have their own methods. And the techniques must be skillful, the force must be even, and the scale must be appropriate. For example, when casting a sword, the pinch of the heat, and the severity of the beating are all related to the quality of the sword. "Where the mirror is cast, the mold is made of gray sand, the copper is made of tin, and the open surface is made of light, the mercury is possessed." All kinds of skills are acquired by craftsmen over time, not overnight.
The process of making things also needs to be rigorous. From beginning to end, do not slack off. If there is a mistake, all previous efforts will be wasted. Every process must be treated with care, such as weaving, weaving, interweaving warp and weft, a little bit methodical, to get beautiful brocade.
After the thing is formed, it still needs to be inspected. Observe its shape, observe its quality, and try its use. If there is a flaw, it must be corrected in time. In this way, the made thing can reach the best state and be passed down for a long time.
