BALL CLAY

Ball clays are fine-grained, highly plastic clays used in manufacturing ceramic whiteware and sanitary ware. 

They usually contain three minerals – kaolinite (20-80%), mica (10-25%) and quartz (6-65%). Ball clays have the unique properties of extra plasticity, enhanced unfired strength and exhibit light color on firing. 

Selected ball clays can even give pure white end products, making their applications widespread. It is often referred to as plastic clay.
