The chemical properties of this product are as follows:
This product is refined by a wonderful method at the intersection of yin and yang and the harmony of the five elements. Its nature is mild, not strong or impatient, just like the warm sun in spring, and it is surrounded by all things without disturbing its stillness. When it encounters water, it melts, like water and milk, without disobedience. After it is integrated into the water, the water body is clear, and there are no impurities to disturb its clarity, just like a clear spring in the mountains, smart and fresh.
When it encounters fire, instead of helping it burn, it seems to have the power to restrain it. When the flames touch it, the fire gradually weakens, as if it is pressed by an invisible hand. The reason for this is that because the product contains the property of yin, it can check and balance each other with the masculinity of fire, and overcome stiffness with softness to make the flame dissipate heat.
When it encounters all kinds of gold stones, it can be affectionate with each other. Or seep into the texture of gold stones to make their texture more tough and dense; or attach to the surface of gold stones, such as wearing colorful clothes, increasing their luster and adding their charm. And it is not easy to react violently with common acids and alkalis. It is like being independent from the world and not disturbed by the outside world.
Buried in the soil, it can communicate with the breath of the soil. It can nourish the soil and make the barren soil gradually fertile and full of vitality. It is interdependent with the soil, like a symbiotic state, making the soil more mellow.
This product has unique chemical properties, which not only conforms to the nature of all elements, but also shows different characteristics in the interaction with each element. It is unique between heaven and earth, and it is a spiritual object that combines nature and magic.

This product is mainly used in many fields, try to describe it in detail in the ancient classical Chinese style of "Tiangong Kaiwu".
In the domain of agriculture, it can help the production of farming implements. If the scorpion, plowshare and other things, this product can cast good materials for them. It makes the scorpion tough and durable, and enters the soil smoothly. When plowing the land, it will not be easily damaged, and it can improve the efficiency of farming. It helps farmers to plow deeper and carefully in the fields, so as to facilitate the growth of crops and hope for a bumper harvest.
In the field of handicraft industry, it also has great potential. For example, loom parts in the textile industry, with this product, the loom can operate more smoothly and smoothly. When the silk thread travels through, the parts are stable and not shaken, and the woven fabric has uniform texture and fine texture. Another example is ceramic firing. This product can participate in the construction of the kiln to ensure the constant temperature in the kiln, so that the ceramic firing temperature is accurate, and the color and texture of the finished product are of the best condition.
It is also indispensable in building construction. When building a house, it is used as a material for beams and columns, which can carry huge weight and make the house strong and durable. And in the connection of the tenon and mortise structure, its characteristics can make the tenon and mortise fit tightly, and it can still stand after years of wind and rain. The construction of the city wall and the reinforcement of this product can resist the intrusion of foreign enemies and ensure the safety of the people.
In the road of military weaponry, its role is also obvious. Build weapons, such as swords, guns and halberds, with sharp and tough edges, which can exert strong power on the battlefield and defeat the enemy. Armor production, choosing this product can improve the protection performance, effectively resist the enemy's blade arrows, and protect the soldiers.
In short, this product is widely used and can play an important role in agriculture, industry, construction, military and other fields, which is the key to the national economy and people's livelihood.

There are many ways to make this product, each with its own subtlety, and choose the important one to describe.
First, the selection of materials is the key. It is necessary to select the best materials, and their texture and quality are all related to the quality of the product. As "Tiangong Kaiwu" said, "All things become quality after fire, and those who become quality must be made of things." The selected things, whether natural stone, flexible wood, or refined metal, need to be screened by the discerning eye to ensure that they are pure and free of impurities and firm in texture.
Second, the method of shaping. Shaping needs to be done according to the nature of the material and the needs of the use. If it is the shape of an artifact, or carved to make it exquisite, or cast a mold to determine its regulations. When carving, the craftsman carries a knife like a pen, depending on the texture of the object, or carves lightly to show its delicacy, or chisels deeply to show its thickness. The method of casting molds is to make the appearance first, using sand, mud, etc. as materials, to be molded, pour in the melt, cool and shape. In this process, the control of temperature and the control of time are the keys to shaping. If there is a slight difference, the shape will be inaccurate.
Third, the order of processing. The processing steps are orderly. First rough and then fine, first fine and then fine. At the beginning, remove the excess material to make the artifact take shape. This is rough work. Then, finely grind the surface to make it as smooth as a mirror, with a clear texture; refine the edges to make it uniform and without thorns. And during processing, it is necessary to apply maintenance methods in a timely manner to prevent damage to the material. For example, wood is often coated with paint wax, and metal is prevented from rusting.
Fourth, the art of combination. If the product is composed of multiple parts, the combination needs to be tightly sewn. Or use the method of tenon and tenon, with the concave and convex fit of the wood, without the need for nails and riveting, and the firmness is abnormal, which shows the ingenuity of the ancients; or use a bonding agent to choose the appropriate agent according to the nature of the material, so that it is closely connected and seamless. When making, it is necessary to consider the force of the components and the smooth connection to ensure the stability and coordination of the product as a whole.
All of these are important methods for the production of the product, which require craftsmen to carefully consider and skillfully handle in order to produce excellent products.

Looking at the market price of this product, it is difficult to determine an exact number. The market is fickle, and many factors are intertwined, resulting in price fluctuations.
Let's talk about what is recorded in "Tiangong Kaiwu", the price of various things in the world also varies with supply and demand, materials, craftsmanship, etc. Today's product, if the material is excellent, is taken from a rare place, strictly selected, and its price is high; if the craftsmanship is complicated, skilled craftsmen are required. After multiple processes and careful carving, the cost will increase and the price will be considerable.
Furthermore, the situation of market supply and demand also affects the price. If this product is widely popular, people are competing to buy it, and the supply is in short supply, its price is bound to rise; on the contrary, if the market is saturated and the demand is few, the price may be lower.
There are similar competing products, which is also the key to affecting the price. If there are many competing products and each has its own characteristics, in order to compete for the market, a price war may be inevitable, and the price of this product may be affected and changed.
From this perspective, the market price of this product is roughly within a range, depending on the above factors. Although it is difficult to specify the specific number, it can be roughly based on comprehensive considerations such as materials, craftsmanship, supply and demand, and competing products to measure the price range.

When making this thing, you need to pay attention to many matters. The choice of the first material should be the one that is well-suited and suitable. For example, if you make a sword, the iron material needs to be tough in texture and high in purity in order to cast a sharp and sharp blade. If the material is not good, the finished product will be easy to fold and fragile, and it will be difficult to make a good product.
The second is the essence of the craftsmanship. Each step must be carried out strictly in sequence and cannot be wrong. Take porcelain as an example. From kneading mud, shaping, to firing in the kiln, the heat and duration are all fixed. If the heat is insufficient, the porcelain will be loose; if the heat is too high, the porcelain will crack easily. When shaping, you must also be skilled in order to form a fine and beautiful shape.
Furthermore, the benefit of tools is indispensable. If you want to do good work, you must first sharpen its utensils. Appropriate tools can get twice the result with half the effort. Such as woodworking sawing and planing, if the edge is sharp, the cutting and planing will be smooth, and the surface of the utensils will be smooth and the size will be accurate.
Also need to pay attention to the environment. Some production processes are strict on the environment. Such as dyeing and weaving, temperature and humidity have a great impact. If the humidity is too high, the dye will easily spread and the pattern will be blurred; if the temperature is not suitable, the dyeing effect will not be good, and it is difficult to get bright colors.
The producer should be more focused and attentive. If you are impatient, the operation will easily make mistakes. Every knife and every stroke is devoted to giving the utensils a soul and making them extraordinary, rather than shoddy products. Only by paying attention to various aspects such as materials, craftsmanship, tools, environment, and mood can we produce high-quality products.
