Underglaze decoration

Definition

Underglaze decoration refers to a technique in ceramics where designs are applied to the clay body before the glaze is added. This method allows for intricate and vibrant patterns to be incorporated into pottery, as it prevents the colors from running or blending during the glazing process. The technique was especially prominent in the creation of blue-and-white porcelain, where cobalt oxide was used to achieve the signature blue hues.
