Ball Clay

Ball Clay. Ball clays are hydrous aluminum silicates of approximate formula Al 2 O 3, 2SiO 2 2H2O. They are inert (insoluble, non-flammable, non-decomposing, non-polymerizing) and non-toxic by ingestion. See 'Silica' for more information. Ball clays contain free quartz, in some cases up to 25%. Do not breathe dust.

Ball Clay | Imerys

Ball clays are kaolinitic clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% quartz, as well as organic matter. Ball clay is formed from the weathering and transportation by water of parent rocks. Seams in the same deposit will vary in composition, depending on the quantity of the principal and accessory minerals.
