Kaolin

Mineral used in pre-historic times. Presumably the most important mineral in clay used in pre-historic pottery. Kaolinite, by name, was known since the Yuan (Mongol) dynasty in the thirteenth century as "Kaolin earth" and was first properly described by Song Yingxing in 1637 in his book Tian Gong Kai Wu (translated: "Introduction to Heaven's Handicrafts" or "The Exploitation of the Works of Nature"). Its usefulness was introduced to the West by a French priest in 1712 (de Fourestier, 2005). Found largely in masses - clay beds - usually with a bright white color, also pale yellow to light brown color due to staining or mixture, rarely blue to blue gray.

APPLICATION:

Kaolinite clay can be used as a ceramic material, paper raw material, rubber and plastic filler, refractory material and other materials, and can also be used to synthesize zeolite molecular sieves and fillers for daily chemical products.
