Abstract

The ceramic products after firing are placed in an atmosphere of water vapour at 100-500 degrees C. at a pressure near atmospheric for a sufficient time, usually 1-4 hours. to undergo a pre-expansion. The temp. is attained during cooling after firing or by reheating the prods. after they have left the kiln. The process is suitable for terrcotta products such as bricks and tiles and can easily be operated with the kilns normally employed.
