To sum up, there are the following aspects: 1. Good plasticity. Taking purple mud as an example, its liquid limit is 33.4%, the plastic limit is 15.9%, and the index is 17.5. It is highly plastic and can be processed into different shapes of different sizes. It has strong adhesion during production, but it does not stick to the tool. If the mouth and the handle can be made separately, and then glued to the body of the pot, the mud can be processed and processed; the clay piece of the squareware can be bonded with grease (more water can be added) and then processed. Such a large process capacity provides a material guarantee for the ceramic artist to fully express his creative intentions and display his craft skills. 2. The drying shrinkage rate is small. Zisha pottery is about 8% from the formation of the mud to the firing shrinkage, the firing temperature range is wide, the deformation rate is small, and the green strength is large. Therefore, the mouthpiece of the teapot can be tightly stitched, and the outline of the shape is tight and not twisted. The handle can be thicker than the porcelain pot, not afraid of the round surface of the pot, so that it can be combined with the mouth. In addition, it can be used as an open vessel and a large-mouth teapot with the same mouth and body. 3. The purple sand mud itself can be made into ceramics without adding other raw materials. The finished pottery has a double pore structure, one is a closed pore, which is a pore inside the agglomerate; and the other is an open pore, which is a group of pores wrapped around the agglomerate. This makes the purple sand pottery have good gas permeability. The fine pore density is high and has a strong adsorption force, and the function of the glazed ceramic teapot is relatively lacking. At the same time, the teapot itself is a precise and reasonable shape. The pot mouth lid is tightly matched, and the displacement tolerance is less than 0.5mm, which reduces the flow of air mixed with molds such as aflatoxin into the pot. Therefore, the color and fragrance of the tea leaves can be maintained for a long time, and the time for the tea to deteriorate and blemish is relatively delayed. Its hot and cold revival performance is also good, even if it is brewed into boiling water, it will not burst into cold water. 4. Zisha clay does not need to be glazed after molding. It has a smooth and smooth shape. The longer it takes, the longer it will take, the more light it will be. This is also unmatched by other textures of clay. It is precisely because of the excellent performance of Zisha Tao, coupled with the skillful production techniques, scientific production skills, multi-colored utensils, and its practical functions, it can become a world famous pottery.
