Ball clay - Wikipedia

Ball clay. 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 plastic in ...

The chemical composition of clay is permanently altered by firing. Firing may take place in an oxygen atmosphere, or in reduction. This will affect the color of the glazes or the clay by affecting the chemical compounds at the surface. Iron, for example, tints ceramics the familiar terra cotta color of roof tiles if fired at a low temperature ...

Industrial Minerals - Ball Clay

Ball Clay (or plastic clays), is a kaolinitic mineral clay and a member of the phyllosilicate group of minerals. It occurs generally as an aluminium silicate comprising weathered forms of quartz, mica and kaolinite. Although similar in chemical composition, BALL CLAY is not as common as kaolin and differs substantially in physical characteristics.

Introduction to Glaze Composition

BALL CLAY is a commonly used clay in glazes and in clay bodies, and is a source of SILICA and ALUMINA. KAOLIN is another commonly used clay, very white in color, used in glazes and in the formulation of Porcelain clays in particular. FELDSPAR is probably the single most commonly used glaze ingredient. It is a natural mineral, derived for granite.
