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.
Ball clays are kaolinitic sedimentary clays that commonly consist of 2080% kaolinite, 1025% mica, 665% quartz. Localized seams in the same deposit have variations in composition, including the quantity of the major minerals, accessory minerals and carbonaceous materials such as lignite. They are fine-grained and plastic in nature, and, unlike most earthenware clays, produce a fine quality white-coloured pottery body when fired, which is the key to their popularity with potters.
