Materials used in the manufacture of Ceramics

Fire Clay

Fire Clay

It is the refractory nature of the high alumina fireclays that make them so valuable in the manufacture of firebricks and other heat resistant ceramics such as saggars.

The vast majority of British fireclays are Carboniferous, usually occurring within the Coal Measures. Consequently their distribution is a very wide one. They are either extracted by open cast methods or mined simultaneously with coal.  Silica content ranges from 40% to 80%. Alumina content lies between 12% and 40%.
