glazing
Quick Summary
Glazing in ceramics involves applying a mixture of powdered materials, often including premelted glass, to a ceramic body. This mixture is typically suspended in water and applied by spraying or dipping. After drying, the object is fired, causing the glaze to fuse into a glassy coating.12
Early earthenware vessels were sometimes varnished or glazed to overcome porosity, preventing liquids from seeping through. This glazing process seals the pores of the clay body, making the pottery nonporous. While early glazing was for practical reasons, it quickly evolved into a decorative technique as well. Glazes can be transparent (like feldspathic, lead, or salt glazes) or opaque (like tin glaze). Different types of glazes and their application methods are used for earthenware, stoneware, and porcelain, influencing the final appearance and properties of the ceramic piece.23
