Lacquered Glass

LACQUERED GLASS Enamels are soft powdered coloured glass that are mixed with a medium and painted onto the glass with a brush. Deposits of special mineral pigments on the glass surface which vitrify at the annealing or tempering temperatures are stable, non-biodegradable deposits, and can be produced in one or more colours, and in different figures (tips, letters, and pads). When the medium is dry, the glass is placed in a kiln for firing. Enamelled glass is tempered or heat-strengthened glass, one face of which is covered, either partially or totally, with mineral pigments. In addition to its decorative function, enamelled glass is also a solar ray controller. Glass is covered by some metallic oxide, and rendered opaque by the presence of arsenic trioxide, or an equally fusible transparent glass, mixed with some opaque infusible powder. It is always applied as a pigment, and is fixed to the glass background by heat. It is essentially a glass, and by heat should become partially incorporated with the glass upon which it is painted.
