Firing is a crucial process in ceramics that involves heating clay and glazes to high temperatures in a kiln. This step serves multiple essential functions, but its primary role is to strengthen the ceramic pieces and help set the glaze. During firing, the clay undergoes chemical changes that transform it from a fragile, workable material into a hard, durable product. The heat causes the clay particles to bond together more tightly, increasing the piece's strength and durability.

Additionally, when glazes are applied to ceramics, firing also causes chemical reactions within the glaze materials. These reactions result in the formation of a glass-like surface that is often decorative and functional, protecting the underlying clay body while enhancing aesthetics. The proper firing can lead to vibrant colors, a glossy finish, or even textured surfaces, depending on the specific glaze used.

While other aspects related to ceramics, such as finishing decorative details, creating surface textures, or adhering pieces together, are important in the overall process of ceramics, they do not encapsulate the fundamental purpose of firing as effectively. Finishing details typically occur after the bisque firing and before glaze firing, while adhering pieces together often involves techniques such as scoring and adding slip prior to firing.
