Ball Clay

Ball clays tend to be quite refractory (PCE 34) and some less processed deposits are sold as fireclays. Ball clay is not a clay mineral in itself, but contains other minerals, primarily kaolinite (but also montmorillonite, halloysite, and illite). Mica and quartz are also present in substantial amounts (e.g. 20% for Tennessee ball clays).
