What is process of heating clay?

The process of heating clay, known as firing, involves subjecting it to high temperatures in a kiln. This process transforms the raw clay into a hard, durable ceramic by causing chemical and physical changes, such as the removal of moisture and the vitrification of minerals. Firing typically occurs in two stages: bisque firing, which strengthens the clay body, and glaze firing, which adds a glassy finish. The specific temperature and duration depend on the type of clay and desired outcome.
