Abstract: The physical, chemical and mineralogical characteristics of clays used in the ceramics industries are briefly outlined. Clays used include ball clays, fireclays, high-alumina clays of the diaspore and burley types, and three-layer types. The high temperature phases and bonding characteristics are briefly reviewed as are the uses of these various clays in the structural clay products, whitewares and refractories.

The importance of clays in the past for ceramics and, in particular, refractories is reviewed and evaluated for future importance.
