La description
Ball Clayis an extremely
rare mineral found in very few places around the world. The term
"Ball Clay is applied to those plastic "transported" clays which
when fired in an oxidising atmosphere to the temperature of certain
pottery ovens- approx ***0°****0°C have a white or nearly white
colour.
Why So-called Ball Clay?
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 *0 cm. As the corners were knocked through
handling and storage these cubes became rounded and ‘ball’
shaped.
Â
Ball clays contain three dominant minerals: from ****0%
Kaolinite, ****5% mica, and ***5% quartz.
In addition, there are other 'accessory' minerals and some
carbonaceous material (derived from ancient plants)
present. The wide variation both in mineral composition and in
the size of the clay particles results in different characteristics
for individual clay seams within a deposit.
