Ceramic glazeWikipedia
Ceramic glaze is an impervious layer or coating of a vitreous substance which has been fused to a ceramic body through firing. Glaze can serve to color decorate or waterproof an item. Glazing renders earthenware vessels suitable for holding liquids sealing the inherent porosity of unglazed biscuit earthenware. It also gives a tougher surface. Glaze is also used on stoneware and porcelain.
