Benzenesulfonicacid,2,2’-(1,2-Ethenediyl)Bis[5-[[4-[Bis(2-Hydroxyethyl)Amino]-6-[(4-Sulfophenyl)Amino]-1,3,5-Triazin-2-Yl]Amino]-,Tetrasodiumsalt

The main use of this product is recorded in "Tiangong Kaiwu". It is related to people's livelihood and has great functions in many fields such as agriculture and industry.
In agriculture, many agricultural tools are actually common uses for such products. For example, Leixiao, it is a tool for turning the soil. "Tiangong Kaiwu" says: "The system of Leixiao is the handle, and the length is six inches. The name of the hook in the middle is not suitable, and the length of the ruler is one inch." Farmers hold the Leixiao to plow, breaking the soil and turning the ground, making the soil loose, which is conducive to the sowing of seeds and the growth of crops. There is also a water wheel, which is a sharp tool for irrigation. " Where there is a roller coaster on the riverside, the weir is blocked by the flow, it is circled under the cart, the wheel is excited to turn, and the water is pulled into the tube, one by one in the water, and flows into the mu. "The waterwheel borrows the power of the flow of water to lead the water to the fields, so as to relieve the danger of drought in the farmland and ensure the moisturization of the crops.
Industrial use is also quite extensive. In terms of ceramic firing, the sagger is the key product." There are two kinds of porcelain billets, one is the printing billet, and the other is the round ware. Where the round ware is made, the wheel is rotated with a billet of mud, and the iron ring is first applied, and it is stamped with an impression. After that, the billet is loaded with the car, and it is rotated one by one. The s During the firing process of ceramics, the sagger can protect the porcelain blank from the direct impact of the kiln fire, making the firing more uniform and improving the quality of the porcelain. Furthermore, in metal smelting, the crucible is an important tool. "Where iron is merging and cooked, it is raw when it is not fried when it is out of the oven, and it is cooked when it is fried. When it is raw and cooked, it is steel when it is refined. When it is smelted, the crucible contains iron and stone, and the wind blows to smelt it." The crucible is resistant to high temperature and can hold ore. The gold is smelted at high temperature to obtain the required metal materials.
In short, such products played an indispensable role in ancient agricultural cultivation, irrigation, industrial ceramics, metal smelting, and many other important matters related to the national economy and people's livelihood, which greatly promoted the development of production and civilization in ancient society.

A product has physical and chemical properties, detailed as follows:
Physical properties
1. ** Appearance **: This product is crystal clear, like ice jade carving, pure and flawless, refracting a soft halo under light, which is loved by the eyes. Its shape is regular, like a natural craftsmanship, and the proportions of each part are coordinated, showing the beauty of symmetry.

This method of making utensils is quite exquisite. According to the records in "Tiangong Kaiwu", the details are described below.
Anyone who makes this utensil should first choose good materials. The material needs to be tough in texture and delicate in texture before it can be used. If it is made of wood, it is advisable to choose sandalwood, Nan and the like. This kind of wood is solid and durable, and has natural beauty. For stone makers, choose white marble, Qingtian stone, etc., whose texture is warm and easy to carve.
After choosing the material, it is the skill of carving. The method of carving is the first to design. The craftsman needs to have hills in his chest and exquisite ideas, and clearly outline the shape and tattoo of the utensils in his heart. Then he works on the knife, transporting the knife like a pen, or cutting or chipping, or carving or engraving. In the line, seek its fluency and naturalness, and be tactful; in the pattern, seek its vividness and lifelike, with both form and spirit. If you carve flowers, you must make the petals roll up and the stamens looming in them; if you carve auspicious beasts, make them strong and majestic.
In the meantime, it is also important to cooperate with the heat and craftsmanship. If you fire ceramic utensils, the heat is very important. It is necessary to grasp the right moment to make the kiln temperature even and moderate. If the temperature is too low, the texture of the utensils will be loose and the color will be dull; if the temperature is too high, you may not be deformed or damaged. When the kiln is fired, the craftsmen stay by the kiln day and night, watching the change of the heat, adding firewood and reducing the fire at the right time, and dare not slack a little.
As for the making of metal utensils, the metal is first melted into a liquid and poured into a prefabricated mold. After it is cooled and formed, it is then polished and modified. The grinding work is meticulous, so that the surface of the utensils is smooth like a mirror and flawless. Or gilt or wrong silver on it to add its luxury.
The making of this utensil, all kinds of craftsmanship complement each other, and the craftsman can create a good product with exquisite skills and concentration. Every step contains the wisdom and ingenuity of the ancients.
