Ball Clay

Ball clays is fine grained, highly plastic sedimentary clays, which fire to a light or near white color. They are used mainly in the manufacture of ceramic whiteware and are valued for their key properties of plasticity, fired strength and their light fired color.

Ball clays exhibit highly variable compositions and consist of a mixture, primarily of kaolinite, mica and quartz, with each contributing different properties to the clay. The crystallinity of the key component, kaolinite, has a marked influence on ceramic performance.
