Why is it called bisque fire?
Most often when potters talk about the first firing of clay, they use the term bisque fire. During the bisque fire clay is transformed from raw greenware clay to ceramic material. The ceramic ware that is produced by a bisque fire is hard and porous. That means that if it gets wet it will absorb water.
What bisque feels like?
Greenware is clay that has been shaped into an object but that has not yet been fired. Bisque is greenware that has gone through the first bisque firing. Once clay has been fired and become ceramic, it is hard and no longer workable. Greenware may look and feel completely dry, once it has reached the bone dry stage.
What is bisque fired?
