Clay is an essential raw material in ceramic prod- ucts, comprising 25- of the ceramic body. Kaolin, however, is only one of a number of clays used in this industry. Kaolin makes up an average of 25% of earthenware, 60% of porcelain, 20-30% of vitreous-china sanitary ware, and 20% of electrical porcelain and wall tiles.

The particles of hard kaolin would disperse at the approximate point (pH=7.3±) of zero net proton charge of edge surface of the kaolinites. The well ordered soft kaolin loosely aggregated. The essential mineral kaolinite may form the soft kaolin clay in edge surfaces to face surfaces ("EF") of kaolinite.
