Glazes can be applied with a brush or the entire piece can be carefully dipped into a glaze bath. After the glaze firing temperature of 2350 degrees f. It also gives a tougher surface. For success a potter must know the correct temperature range at which their glaze becomes mature.

Ceramic glaze refers to a vitreous substance fused onto pottery through firing. It is important to match the firing temperature of the glaze to the maturing temperature for the particular clay body. Glazes often require multiple coats and a lot of patience to get them just right. The type of kiln used and the firing schedule will also have an effect on the color and texture of the glaze.

Glaze can serve to color decorate or waterproof an item. As well as firing clay the glaze must also be fired to maturity. For earthenware such as fired clay pottery to hold liquid it needs a glaze.
