Where translucency and whiteness are paramount, highly plastic kaolins and white burning ball clays and bentonites can be used . Because kaolinite mineral has a much larger particle size than ball clay and bentonite materials, blending it with them in bodies can produce a good cross section of ultimate particle sizes (this imparts enhanced working and drying properties).asbestos in kaolin clayKaolin, commonly referred to as china clay, is a clay that contains 10-95% of the mineral kaolinite and usually consists mainly of kaolinite (85-95%).
