Ceramic firing is a process used to harden clay and transform it into durable pottery. This involves heating the clay in a kiln to high temperatures, typically between 1,800°F and 2,400°F (1,000°C to 1,300°C). The heat causes chemical changes in the clay, making it strong and waterproof. There are two main types of firing: bisque firing and glaze firing. Bisque firing is the initial stage that removes moisture and makes the clay easier to handle. Glaze firing follows, where a glass-like coating is applied to enhance the appearance and functionality of the pottery.
