FAQ

What is the chemical structure of this product?

The chemical structure of this product is a finely constructed thing at the microscopic level. As stated in Guanfu's "Tiangong Kaiwu", although it is not stated bluntly, it can be seen from the ancient way of knowing things.

The composition of matter is based on atoms and molecules. Atoms are like the dust of heaven and earth, each has its own characteristics, and is arranged in a delicate order to form all things. Molecules are formed by the connection of atoms, and their structure is ingenious, like the work of heaven.

Just like ore smelting, the metal elements contained in the ore are arranged in a specific lattice structure. During smelting, after high temperature calcination, the order of the lattice changes, and the bonding state of the atoms changes, resulting in pure metals. The atoms of this metal, or arranged in a tightly packed manner, are connected to each other by metal bonds, so that the metal has good electrical conductivity, thermal conductivity and ductility.

Another example is the oil produced by plants and trees, and its molecular structure is mostly fatty acid glycerides. Fatty acid parts, with different lengths of carbon chains, or straight or branched chains, and their unsaturation levels are also different. Glycerol is connected to fatty acids with hydroxyl groups, forming the basic structure of oil molecules. This structure gives oil unique physical and chemical properties, such as insoluble in water and soluble in organic solvents.

And like the fibers used in fabrics, natural fibers such as silk, its main component is protein, molecules are connected by amino acids with peptide bonds to form chains, and the chains are interacted with hydrogen bonds to make silk soft and shiny. And man-made fibers, such as those synthesized by chemical methods, have molecular structures designed according to the characteristics and actual needs of the imitated natural fibers. The monomers are connected by polymerization reaction to form a regular or specific arrangement of macromolecular chains, giving the fibers different properties.

From this perspective, the chemical structure of the product is actually a combination of natural wonders and artificial ingenuity. In a microscopic order, it is in a macroscopic state, laying the foundation for the use of all things.

What is the preparation method of this product?

The manufacturing method of this utensil is particularly complicated and exquisite. Looking at its shape and craftsmanship, it is unique.

At the beginning, the selection of materials needs to be extremely fine. Materials with tough texture and fine texture must be selected, such as high-quality gold, silver, copper, or beautiful jade, good wood, etc. Taking gold as an example, it is necessary to select pure, remove impurities, and make it pure in texture, in order to lay the foundation for the subsequent process.

The method of casting is also exquisite. In terms of the mud model method, the clay mold is first molded, and the shape and decoration of the utensil to be created are carefully carved on the clay mold, and there must be no mistake at all. When the mud is turned back, the seams must be tight to prevent the leakage of the molten metal during casting and the leakage of the utensils.

When casting, it is crucial to control the heat. If the temperature of the fire is high, the molten metal flows smoothly and can fill all parts of the fan cavity; if the temperature is low, the liquid is thick and difficult to form. Craftsmen need to rely on experience and eyesight to observe the fire and distinguish the color of the fire, and pour the molten metal into the fan at the right time, and wait for it to cool and solidify.

After the utensils are formed, they need to be refined. If it is a metal ware, it needs to be polished to make its surface as smooth as a mirror, showing the luster of metal; if it is a jade ware, it is carved with a mound and decorated according to the texture trend of the jade material, giving it a smart state. In the meantime, every knife and stroke contains the blood and skills of the craftsman.

As for the method of decoration, or carving, engraving exquisite patterns on the surface of the utensil; or inlaying, with gems, pearls, etc. embedded in the body of the utensil to increase its magnificence. Such various crafts cooperate with each other to create exquisite utensils. This manufacturing method is actually the crystallization of the wisdom of ancient craftsmen and has been passed down to future generations, which is amazing.
