A
glaze is a glossy or glassy film that is fused to the ceramic body
during firing. It is usually formed from powdered minerals added to
water and washed or painted over the object. A glaze can be shiny or
matt, hard or soft
After application, the ceramic is fired, and the powdered coating melts into a hard, glass-like coating. A ceramic glaze is usually for decoration or protection and most glazes can be considered specialised forms of glass.
Glazing is functionally important for earthenware vessels, which without it would be unsuitable for holding liquids. In addition to the functional aspects, aesthetic forms include a smooth pleasing surface, the degree of gloss and variegation, and finished color.
Ceramic glazes can also enhance an underlying design or texture which can be the natural texture of the clay or an inscribed, carved or painted design.

Can be applied by dipping pieces directly into the glaze, pouring the glaze
over the piece, spraying it onto the piece with an airbrush or similar tool,
with a brush, or with any tool that will achieve the desired effect.
To prevent a glazed article sticking to the kiln during firing either a small part of the item is left unglazed or special supports, called kiln spurs, are used then removed and discarded after the firing. Small marks left by these spurs can sometimes be visible on finished items.
Good early antique Derby porcelain figures without base marks can usually be identified by the three pad marks left by the supports Derby used during the firing.

Early Earthenware
Glazes
These were
usually based on lead and tin, which produced an opaque white finish. Early soft-paste
porcelain has a colourless lead glaze, but later soft-paste porcelain
had crushed flint or glass added to the glaze.
Lead glazes
were used until the 19th century when less dangerous materials were found.

Tin glaze
chips easily but provides a white ground that was perfect for colour decoration.

Salt glaze Stoneware
has an orange peel effect produced by throwing salt into the kiln during
firing.

Crackle
glaze, cracklure or crazing - occurs when the ceramic body and the glaze shrink
at different rates, as they cool. A crackle glaze is highly desirable on some
items; particularly Japanese Satsuma wares.
