About Ceramic glaze

(From Wikipedia)
A glaze is a specialised form of glass and therefore can be described as an amorphous solid. Glazing is the process of coating the piece with a thin layer the raw materials which, after being fired in a kiln, will form a hard, glass-like coating.

Glazing is functionally important for earthenware vessels, which would otherwise be unsuitable for holding liquids due to porosity. Glaze is also used on functional and decorative stoneware and porcelain. In addition to the functional aspect of glazes, aesthetic concerns include a variety of surface finishes, including degrees of gloss and matt, variegation and finished color. Glazes may also enhance an underlying design or texture which may be either the "natural" texture of the clay or an inscribed, carved or painted design.
