What are the chemical properties of this product?
The chemical properties of this product are related to its essential characteristics and are of paramount importance. Although there is no direct and detailed description of the chemical properties of this product in Guanfu's "Tiangong Kaiwu", the characteristics of various things involved in it can be referred to in detail.
As far as common materials are concerned, their chemical properties involve reactivity and stability. Such as metal materials, they are often oxidized and prone to changes in contact with air and water vapor. Copper ware is gradually patina on the surface after years of circulation. This is the reason why copper reacts with oxygen, water, carbon dioxide, etc. in the air.
In terms of ore products, its chemical properties are complex and diverse. Ores contain various metal elements and other compounds, which will decompose and combine under high temperature and the action of specific reagents. Such as iron ore, when smelting, it is placed in a blast furnace with coke, limestone, etc. After high temperature, iron oxide in iron ore reacts with carbon monoxide, and iron is reduced. The chemical changes are complicated, which is related to the reactivity and chemical affinity of various substances.
Another example is grass and wood products, the main components of which are mostly cellulose, lignin, etc. Such substances are flammable. When burned, they react violently with oxygen to release heat energy. And in an acid-base environment, corresponding chemical changes, such as hydrolysis, will also occur, changing its original structure and properties.
However, because I don't know the specific meaning of this product, it is difficult to accurately detail its chemical properties. However, according to the principles of "Tiangong Kaiwu", the chemical properties of all things in the world are affected by their constituent elements, molecular structures and external environments. Or it has active reactivity, easy to combine and decompose with others; or it has high stability and can remain unchanged over time. It is necessary to investigate in detail according to its specific ingredients and environment to know its exact chemical properties.
What are the physical properties of this product?
The physical properties of this product are as follows: its quality is firm and dense, like the solidity of gold and stone. Looking at its color, it is warm and lustrous, or it is blue and blue, like water in a pool, clear and deep; or it is red and brown, like Danxia reflecting the sun, gorgeous and eye-catching. Its surface is smooth, and it is as smooth as touching grease, delicate and smooth.
As for its weight, it is moderate in weight. It is held in the hand, and it has a sense of calmness without being overly tired. It is as if it has reached a delicate balance with the palm. Its hardness is quite high, and it is difficult for ordinary utensils to damage it, just like ancient divine utensils, which have not been destroyed through the years.
Its thermal conductivity is also unique. When exposed to heat, the heat flow conducts slowly, without delay, like a warm elder, with a moderate demeanor. When placed in a cold place, the heat dissipation is also slow, and it can maintain its own warmth for a long time, which seems to contain endless warmth.
Furthermore, its light transmission is unique. Under light, it can transmit a little light, and the halo is soft and not dazzling, as if the spiritual energy between heaven and earth is gathered in it, faintly emitting a mysterious and charming atmosphere. This kind of physical properties complement each other, creating the extraordinary characteristics of this product, making it unique among all kinds of items and showing its outstanding elegance.
What is the main purpose of this product?
What are the main uses of this product? In "Tiangong Kaiwu", there may be relevant explanations.
"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. It contains many technological technologies and production processes in detail, and many of them discuss the uses of various products.
In ancient times, many product uses were closely related to people's livelihood, production, military, etc. For example, among metal products, iron farming tools were of great use in agricultural production. Farming tools such as iron plows and iron hoes can help farmers manually translate plowing land, weeding and loosening soil, greatly improving agricultural production efficiency, ensuring food output, and maintaining people's livelihoods.
Ceramic products, one is daily eating utensils, such as bowls, plates, cups, etc., for people to eat and drink, with a warm texture and easy to clean; the other is also used as decorative ornaments. Delicate porcelain has beautiful shapes and gorgeous decorations, which can be displayed in the room to add elegance.
Silk fabrics, the main use is clothing. Silk is soft to the touch and gorgeous in color. It is made into comfortable and beautiful clothes, which are loved by officials and nobles, showing their status. Second, in foreign trade, silk is an important commodity. It is exported to the Western Regions, Europe and other places in large quantities, earning rich wealth for the country and promoting economic and cultural exchanges between China and foreign countries.
Another example is paper, the primary use is to write records. Literati used paper as a carrier to write poetry articles and record historical events, so that culture could be passed on; in addition, paper was also used in packaging and other fields. Although it was not as widely used as in modern times, it was also used to some extent at that time.
All kinds of products are widely used, or related to people's livelihood, or affecting economic and trade, or assisting cultural inheritance. They all played an indispensable role in the development of ancient society.
What are the synthesis methods of this product?
There are many kinds of combined methods of this product, each with its own ingenuity. Let's try to discuss it with ancient methods today, hoping it can be helpful.
First, the selection of materials is the key. It is necessary to choose high-quality things, those with pure texture and flawless dirt-free are better. For example, when casting a sword, choose good iron, which contains less impurities, so that the sword body can be tough and sharp. If the material selection is not good, even with superb skills, it is difficult to become a good product.
Second, the method of processing. Or it is necessary to combine water and fire. For example, the art of alchemy requires precise control of the heat. The size and duration of the fire are related to the success or failure of the elixir. In the production of the product, or first simmer it slowly to make the materials blend and penetrate; then burn it fiercely to promote its qualitative transformation. There are also those who are quenched by water, and the sword can be quenched by water to increase its hardness.
Third, the skill of blending. The ratio of different materials needs to be just right. Like cooking, the amount of seasonings such as salt, vinegar, sauce, pepper, etc. affects the flavor of the dish. In the production of the product, the proportion of each ingredient is slightly deviated, resulting in very different quality. After repeated trials and accurate measurement, the best ratio can be obtained.
Fourth, the inheritance and innovation of skills. The experience of predecessors is a treasure, and it should be carefully studied. However, the times change, it is also impossible to be rigid. If you can combine today's new tools and new concepts on the basis of ancient methods, you may be able to find another way to improve the quality of the product to a higher level. When making, the craftsman's effort and focus are also crucial.
How competitive is the product in the market?
Looking at today's city, what is the potential of a certain product competing in it? It should be explained by the ancient sense. "Tiangong Kaiwu" says: "There are smart naturalists in the world, and thick people are able to push." In the competition of products, it is also necessary to be smart and know the ability of things in order to gain insight into the opportunities.
One is that the material must be good. "Tiangong Kaiwu" says: "Where a mirror is cast, gray sand is used for the mold, and tin and copper are used for the mold." The quality of the product is related to the materials used. If the material is poor, it will be difficult to become a good product. Why compete in the market? If a mirror is cast, copper and tin are well matched, and a good mirror can be obtained. The selection of excellent materials for the product is the foundation of the city.
Second, the workmanship must be clever. " A total of one billet of labor, seventy-two in hand, and a square gram becomes a tool. "Product manufacturing, the process is complicated, and every link needs to be exquisite. Skillful work produces meticulous work, and meticulous work can be better than others. Products in the city, those with exquisite workmanship, are loved by everyone. If they are shoddily made, even if they have a novel shape, they will not last long.
Third, they must be observed at all times." The sky covers the earth, and the number of things is ten thousand, and things are also because of it. They are formed without leaving behind, and it is not easy to lose manpower. "All things in the world change endlessly, and so is the market. It is timely to be able to observe the changes in the situation and know the needs of everyone. Products are born in time. Those who do not observe the times are like sailing against the current, and it is difficult to move forward.
Fourth, Those who are famous are the guests who are real. "The reputation of a product is the reflection of its actual performance. If the product is excellent and the service is good, the reputation will grow. People choose products by reputation. Those who are well-known have a wide market; those who are not well-known have a narrow city.
Today's products want to be competitive in the city, and they need good materials, workmanship, inspection time, and a good reputation. If so, they can be like a boat traveling downstream and traveling freely in the city.
