What is firing and why is it necessary?

Aug 14

Firing is the process of heating clay in a kiln to very high temperatures, turning it from a soft, fragile material into a hard, durable ceramic. This is necessary because unfired clay is not waterproof, strong, or food-safe. The first firing, called bisque firing, hardens the clay so it can be handled and decorated without breaking easily. The second firing, called glaze firing, melts the glaze into a glass-like surface. Different types of clay require different firing temperatures. Firing transforms clay at a molecular level, removing all remaining water and chemically changing its structure. Without firing, your piece would crumble over time. Kilns can be electric, gas, or wood-fired, each producing slightly different results. Firing also affects the final color and texture of the piece. It’s an essential step in pottery making that ensures your work lasts for years.
