What is glaze and how is it used to decorate pieces?

Aug 14

Glaze is a liquid mixture of minerals, glass particles, and pigments applied to bisque-fired ceramics. It serves two main purposes: making the surface waterproof and adding decorative color or texture. When fired, glaze melts and fuses to the clay, creating a smooth or textured finish. Glazes can be glossy, matte, transparent, or opaque. Some glazes create special effects, like speckles or color shifts. Applying glaze can be done by dipping, brushing, pouring, or spraying. The thickness of the glaze affects the final result. Glazes are food-safe if formulated correctly, which is important for functional pottery. Instructors often provide a selection of colors for students to choose from. The final look of a glaze can vary depending on the clay body, application method, and firing conditions.
