Kaolin clay has a high fusion temperature, and its naturally bright white color makes it useful for manufacturing pure white ceramics, porcelain, china, sanitary ware, and kaolin pottery. Because kaolin contains low concentrations of iron or alkalis, it is ideal for use in various forms of ceramics.
Kaolin, a soft white clay, is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, and many other products. It is named after the hill in China (Kao-ling) from which it was mined for centuries.
