The enameling of glass surfaces consists in applying, spraying or with special rollers, a paint on a surface of the glass plate destined to become a part of a piece of furniture (eg tables, doors). This specific processing can be done cold or hot: in the hot case there is a vitrification of the paint following the permanence of it in an oven, usually by the process of tempering. These painting techniques give glass a particular glossy or satin color effect and allow the creation of artistic glass windows for interior architecture and constructions.
