Notes
'Fireclay' is a generic term that in the simplest terms refers to a refractory clay. Typically fireclays are plastic and have significant iron impurities. Light duty fireclays have a PCE of about 27 and superduty materials can melt as as high as cone 32.
Fireclays are useful in many types of ceramics including brick, certain types of tile and sculpture and pottery clays. They impart plasticity and particle size distribution to the body and counter the early melting of any low temperature clays in the mix. For vitreous fireclay based bodies, considerable feldspar content is necessary.
Hundreds of different kinds of fireclays are available. However they are not normally interchangable in body recipes since they vary drastically in plasticity, particle size, fired color, thermal expansion, and mineralogy.
