Chamotte is a calcined clay. The calcination process takes place in a rotary kiln at high temperatures of 1400 - 1600ºC. Sanitaryware pieces are fired at lower temperatures of around 1200ºC, therefore the chamotte is inert at the firing stage and acts like a skeleton to produce ware with better proprieties.

It is the introduction of chamotte that characterizes the production of fine fireclay, which enables the production of bigger and more complex sanitaryware pieces.
