Q. What is white clay used for?

Answer

White clay, known variously as china clay and kaolin, is a soft whitish clay that is mostly used as the principal constituent of porcelain and chinaware pottery. Kaolin has found extensive use in the manufacture of floor and wall tiles, panels, and insulating materials. White clay is also used in the manufacture of paper, interior wall paint, and in the rubber industry as a cheaper substitute for carbon black and silica. Unbeknownst to many, white clay is also used in the cosmetic industry as an additive in toothpaste, face masks, and exfoliants. White clay also finds use in the medical industry as an antidiarrheal drug. The word kaolin derives its name from Kao-ling (aka Gaoling), a hill in China that is abundant in minerals.
