Smalti - Byzantine Glass Mosaic Tile

Byzantine glass mosaic tile or smalti is the type of opaque glass tile used in classical Byzantine mosaics. Smalti is not molded into uniform shapes like modern glass mosaic tile.

Smalti is made by mixing glass and various minerals according to traditional recipes and melting the mixture in a furnace. The molten glass is then poured onto a slab for cooling, and then cut by hand into rectangular pieces. The pieces are about 1/2" or smaller and they aren't perfect rectangles. They vary in thickness, shape, size and color. These natural variations in shape and color are exactly what make smalti the perfect mosaic material and allow the artist to create beautifully detailed images.
