The making of clay cricket POTS goes through dozens of processes. First of all, the extracted river mud is put into a silk basket to filter. (Ancient mud is a special double-layer silk bag hanging in the river. The silt in the river flows into the silk bag. With the change of time, the flow and velocity of water in the river have changed so much that it is impossible to follow the ancient law completely. The extremely fine soil filtered out is the raw material of canning - clear mud. Hence the name of the clay cricket pot. The filter mud will be placed for more than a year, after winter and summer to remove its dryness can be used. Clay pot "from water to fire". This can be traced back to The Alchemy of Chinese Taoism: taking mud from water is like making medicine, and filling pot in fire is like making Dan eventually. In addition to following the ancient method, Shandong cricket can also made innovation by using modern scientific and technological means. In the process of making clay, it purchased mechanical equipment and replaced the original manual operation with electricity. The result is that the density and hardness of the pot are strengthened, and the clay pot will not produce any bubbles and tiny cracks during firing. Generally, the density of clay pot is about 1.2-1.4, but modern technology improves its density to about 1.6-1.8, increasing its usability and suitable air permeability. In ancient times, "Vermilion red, eel yellow, crab shell green, bean green sand, sandalwood purple, black ink, chicken bone white, snow red for the superior color, especially the most precious bean green sand, chicken bone white. Shandong Chengcheng mud cricket pot is made of clay deposited from the Yellow River for thousands of years. It is refined by special fire. It is like jasper, like children's flesh, and can keep rice without rot, severe cold without ice. The ceramicmaking process is the forerunner of cheng-mud process, its development gave birth to cheng-mud process, and the sublimation result of ceramicmaking process is the appearance of porcelain. The process of clear mud is the result of independent development. The appearance of clear mud jars and purple clay ware in history has proved its existence, and it still has its unique artistic charm and value. It is another product between pottery and porcelain, classified as stoneware. Controlling temperature is one of the keys to grasping quality: if the temperature is too high, it will become porcelain, with poor air permeability, which is not desirable; If the heat is not enough when firing, it will burn into pottery, hardness is poor, inside the bran outside crisp. Therefore, the calcination process is the most complicated part in the production of clay pot. The color, hardness and luster of clay pot are all closely related to it.
