China clay lumps, also known as kaolin, are a naturally occurring clay mineral primarily composed of aluminum silicate. These lumps are widely used in industries such as ceramics, where they are a key ingredient in the production of porcelain, tiles, and sanitary ware due to their fine texture, whiteness, and ability to withstand high temperatures. In addition to ceramics, china clay is used in paper manufacturing as a coating and filler to improve brightness and printability, in cosmetics and pharmaceuticals for its soothing and absorbent properties, and in rubber production as a reinforcing agent. Its versatility also extends to paint, plastics, and detergents, where it acts as a thickening agent and helps improve product quality.
