Ceramic glaze is an impermeable layer or coating of a glass like substance which has been fused to a ceramic body through a variety of firing temperatures. Glazes can serve to color, decorate or waterproof an item.

Created from a mix of raw materials, glazes often contain: silica, the main glass former. Several different metal oxides, like sodium, potassium or calcium, which help flux the glaze to lower the melting temperature. Alumina, usually derived from the clay it self, stiffens the molten glaze to prevent it from running off the piece. Many colorants, such as iron oxide, copper carbonate or cobalt carbonate, and also opacifiers such as tin oxide or zirconium silicate, are used to modify the visual appearance and opacity of the fired glaze.
