Kaolin is a non-metallic mineral, which is a kind of clay and clay rock dominated by Kaolinite group clay deposits. Due to its white and delicate appearance, it is also known as Baiyun soil. It is named after Gaoling Village in Jingdezhen, Jiangxi Province.

Pure kaolin is white, delicate and Mollisol like, with outstanding physical and chemical properties such as plasticity and fire resistance. Its mineral composition is mainly composed of Kaolinite, halloysite, hydromica, Illite, Montmorillonite, quartz, feldspar and other minerals.

Kaolin is widely used, primarily in papermaking, ceramics, and refractory materials, followed by coatings, rubber fillers, enamel glaze, and white cement materials, with a small amount used in plastics, paint, pigments, grinding wheels, pencils, etc.
