Ball clay - Wikipedia
Ball clays are kaolinitic sedimentary clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% 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 stone 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.
What is Ball Clay? What are its Properties, Processing ...
ball clay . Ball clay Properties: The ball clay deposit is sedimentary and consists of numerous strata which frequently vary significantly in physical properties although perhaps not much in stone composition.

The ball clay:kaolin mix can be altered to change body plasticity without significantly affecting the maturing temperature. In North America, most commercial ball clays are mined in the southeastern US. Ball clay deposits are common and were laid by the action of slow moving water with an acidity that tended to flocculate and settle the clay.
OM #4 Ball Clay - digitalfire.com
OM#4 ball clay is variable in nature and tends to be more vitreous than some of the more refractory ball clays that are available. It has some soluble salts which can give a brown coloration to the surface, so barium carbonate may be needed to precipitate these.
What is Ball Clay? - Industrial Minerals Association ...
Ball clay is an extremely rare mineral found in very few places around the world. Its name dates back to the early methods of mining when specialized hand tools were used to extract the clay in rough cube shapes of about 30 cm. As the corners were knocked through handling and storage these cubes became rounded and ‘ball’ shaped.
