What is Guanyin soil?

China is the hometown of porcelain and kaolin. "Tiangong Wu Kai Bian Tao" said: "The soil comes from Wuyuan and Qimen Mountain: One Gaoliang Mountain comes from japonica rice soil, which is hard; A civilized mountain, a land of glutinous rice. Its nature is soft. When the two kinds of soil are combined, porcelain becomes. " The so-called glutinous rice soil refers to Guanyin soil. Guanyin mud is an important raw material for ceramic body, glaze and clay refractory. It is the first porcelain material discovered and applied by ancient porcelain workers in Jingdezhen, the capital of China, because it was first discovered in gao ling cun, 45 kilometers east of Jingdezhen, Jiangxi. Now it has become a common term for porcelain raw materials all over the world. In other words, "Guanyin soil" is the unified name of similar clay in the world, and it is a great contribution of China porcelain workers to the world.
