Bisque Firing: How to
Bisque firing is the first firing step in the process of firing and making ceramic pieces. Its the first heating process of clay after its been shaped and before its been glazed. Bisque firing makes raw clay hardened and easier for the glazing process.
Drying: Before your bisque firing the clay must be completely dry.
First Firing (Bisque Firing): The pottery is placed in a kiln and slowly heated to a temperature between 1,600°F (871°C) and 1,800°F (982°C). This process removes any remaining water and organic materials and the clay becomes more stable. The clay undergoes a chemical change, known as "maturing". After this step the clay is strong and stable.
Result: After bisque firing, the pottery is hardened but still allowed to absorb glaze. The pieces are now easier to handle and depending on the clay material you use its typically a light beige, gray, or pink color.
Post-Bisque: After bisque firing, the clay is cleaned by using a sponge and light amount of water, and then it can be glazed and fired again in a higher-temperature glaze firing.
