And it may have a beautiful state, adding a lot of color to the interior decoration, creating an elegant atmosphere. It can also be used as a miscellaneous tool for life, such as buckets and basins, to meet the daily needs of water collection, storage, etc.
Fourth, it plays a significant role in the field of cultural inheritance and artistic creation. Artists can splash ink on the surface of the utensils specially made for this product, leaving a danqing pen; artists can use it as an embryo to display their skills, create sculptures and other works of art, and spread the beauty of culture, allowing future generations to see the exquisite skills and splendor of culture in the past.

The physical properties of the husband's products are various, and it is difficult to describe them. And looking at all kinds of utensils, each varies according to its use and material.
Ordinary products, the first texture. If gold and stone are used as materials, they are mostly hard, can bear load and wear resistance, just like the ancient swords, made of fine iron, sharp and tough, and can last for years without breaking. And those who use wood as the quality are mild, soft and elastic. If good wood is used as a beam, it can support a large building, and there is no shortage of flexibility, so that the house can resist wind and rain.
Furthermore, it is related to density. The genus of gold and silver has a high density, and it has the feeling of sinking, so it can show its value; while bamboo reeds and the like have a low density, are light and convenient, and are often the choice for weaving utensils, such as bamboo baskets and reed mats, which are easy to use and carry.
Also has the property of heat conduction. Metals are more good at heat conduction. They are made of copper and iron as a kettle and placed on a fire, and the heat is fast and uniform, which can make cooking convenient and efficient. On the other hand, clay utensils are slow in heat conduction, but they have good heat preservation. They are used to hold soup and can hold warmth for a long time, making people slow and taste.
As for the extensibility, it is also important. Gold can be beaten into foil, as thin as the wings of a cicada, which is the ultimate extension and is used for decoration, dazzling; while masonry and the like have little extension and solid texture, so as to build a wall and build a foundation, which is very stable.
The physical properties of the product, either related to the beauty of its appearance, or related to the effect of its function. Craftsmen must carefully observe the physical properties and apply it according to the material, in order to obtain exquisite products to meet the needs of the world.

Nowadays, it is asked whether the chemical properties of the product are stable or not. The chemical properties of the husband's products, whether they are stable or not, are related to many things. Looking at the properties of various things, or it is easy to adapt to other things, or it can last for a long time without changing, all of which vary from thing to thing.
If the product is made of various materials, the chemical stability of the product often depends on the quality and method of the material. If the material is pure and stable, the products made are also stable. If the gold casting tool is made of fine gold, the gold nature is stable, and it is rare to respond to other things, so the gold can last for a long time without rusting, which is a sign of its chemical stability.
However, if the method of making is not good, although the material is good, it may also cause the chemical properties of the product to change. For example, in the industry of smelting iron, if the temperature control is improper during forging, or mixed with other substances, the properties of iron will change, and it is easy to rust and rot, so its chemical properties are unstable.
The environment where the product is located is also related to the stability of its chemical properties. Exposure to hot sun and wet moisture, all kinds of products are easily affected by it. If the wood is wet and rotten, and the stone is eroded by rain, it will change its chemical properties due to the change of the environment.
Therefore, whether the chemical properties of the product are stable or not should be considered when considering the material, production method and the environment. If the materials are good, the production method is fine, and the product is in a suitable environment, the chemical properties of the product are more stable; if one is not good, it may cause instability.

What is the main method of making billets of this utensil? The method of making billets is related to the shape and quality of the utensil and is very important. In "Tiangong Kaiwu", there are many techniques of making billets described, which can be used as a lesson.
If making a pottery billet, the method is to first take the clay, which is delicate and sticky. Then, or knead it by hand. This is the most ancient method. With the ingenuity of the craftsman, it is done at will to shape the prototype. There are also pottery wheels that place clay on the wheel and rotate it by hand. The craftsman rotates the wheel, supplemented by pressing and pulling with both hands, so that the clay gradually becomes a regular billet shape. This is the method of wheel system, which is more efficient and uniform.
As for making porcelain billets, the selection of materials is more particular, and more high-quality porcelain clay such as kaolin is taken. In addition to hand-kneading and wheel-making, there are also methods of molding. The mold is made first, and the mold is filled with porcelain clay. After pressing and other processes, the porcelain clay fits the shape of the mold, and it is taken out to form a blank. This molding method can be mass-produced and the shape is uniform.
Casting billets, such as copper casting and other metal utensils. The first thing to prepare is to choose suitable metal raw materials. Often the fan casting method is used to make the mold first, and the model is divided into pottery fan, stone fan, etc. Taking pottery fan as an example, the clay mold is made, and the inner and outer models are made through engraving, decoration, drying and other processes. The metal raw materials are melted into liquid, injected into the fan, and after cooling and solidifying, the fan is broken, and the blank of the utensil is obtained. After subsequent processes such as grinding, the final utensil is completed.
In short, the method of making the blank varies according to the material and purpose of the utensil. Craftsmen need to study all kinds of skills in order to make a good blank body and lay the foundation for the formation of the utensil.
