Firing Greenware

When the cast pieces are dry, the seams and edges are worked smooth. At this point the piece is called greenware. Soft and malleable, this pre-fired clay can be easily shaped by hand.

The greenware travels through a kiln designed as a tunnel where it is fired very slowly. For porcelain, the first firing temperature is more than 2700 degrees, while earthenware is fired at about 1800 degrees.
