Caulino, also known as china clay, is a soft, white clay that is named after the Gaoling (Kao-ling) village in Jingdezhen, Jiangxi Province, China. It has been used for centuries, especially in the production of porcelain and fine china, which explains its alternative name.​

Chemically, kaolin is composed mainly of kaolinite, a hydrous aluminum silicate mineral. Its chemical formula is Al₂Si₂O₅(OH)₄. This mineral gives kaolin its unique properties. It has a fine particle size, high whiteness, and excellent plasticity when wet, making it ideal for various applications.​

In the ceramics industry, kaolin is a fundamental raw material. It helps to create the smooth texture and pure white color that is characteristic of high - quality porcelain. In the paper industry, kaolin is used as a coating pigment. It improves the brightness, smoothness, and printability of paper. Additionally, kaolin finds applications in the paint, rubber, and plastic industries. In paint, it acts as a filler, enhancing the paint's durability and hiding power. In rubber and plastics, it can improve the mechanical properties of the final products. Overall, kaolin plays a crucial role in multiple industrial sectors due to its special properties.
