What is Ball Clay What are its Properties Processing ~ Ball clays are kaolinite rich secondary clay which is available in dark brown to black colour due to relatively high organic impurity content Once it fired it will become white to lite cream colour It consists of three major minerals that are kaolinite mica quartz It is a high plastic clay and contains more fine particles
What is Ball Clay The Kaolin and Ball Clay Association ~ Ball clays or plastic clays are fine grained highly plastic sedimentary clays which fire to a light or near white colour They are used mainly in the manufacture of ceramic whiteware and are valued for their key properties of plasticity unfired strength and their light fired colour
What Is Ball Clay with pictures ~ Ball clay is composed of varying amounts of kaolin mica and quartz It also usually contains other trace minerals and carbon byproducts The raw clay generally varies in color from shades of blue to beige and white depending on the amount of kaolin and iron oxides the mixture contains
