	Most pottery produced in recent centuries has been glazed, other than pieces in unglazed biscuit porcelain, terracotta, or some other types. Tiles are almost always glazed on the surface face, and modern architectural terracotta is very often glazed. Glazed [[brick]] is also common. Domestic sanitary ware is invariably glazed, as are many [[ceramic]]s used in industry, for example ceramic insulators for overhead power lines.

			== Materials used ==

			* 30% '''[[Silica]]''', for a shiny, waterproof glass layer
			* 40% '''[[Feldspar]]''', as flux to reduce melting point
			* 20% Kaolin '''[[clay]]''', for alumina, to stabilize
			* 10% '''[[Calcium carbonate]]''', as both whiting and flux
			* '''[[Water]]'''
			* Other chemicals for colour as desired

			== Crafting instructions ==
			Mix with enough water to form a slurry. Apply to bisque-fired pottery by dipping, pouring, or brushing and let dry before glaze-firing.

			== Uses ==
			Glazing a ceramic is done to ensure waterproofing, to make the surface less prone to dirt and other pollutants, and as decoration

'''Ceramic glaze''' is an impervious layer or coating of a vitreous substance which has been fused to a [[pottery]] 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. In addition to their functionality, glazes can form a variety of surface finishes, including degrees of glossy or matte finish and color. Glazes may also enhance the underlying design or texture either unmodified or inscribed, carved or painted.

Most pottery produced in recent centuries has been glazed, other than pieces in unglazed biscuit porcelain, terracotta, or some other types. Tiles are almost always glazed on the surface face, and modern architectural terracotta is very often glazed. Glazed [[brick]] is also common. Domestic sanitary ware is invariably glazed, as are many [[ceramic]]s used in industry, for example ceramic insulators for overhead power lines.
