Glass tile

Glass tiles are pieces of glass formed into consistent shapes.

Glass was used in mosaics as early as 2500 BC, but it took until the 3rd century BC before innovative artisans in Greece, Persia and India created glass tiles.

Whereas clay tiles are dated as early as 8000 BC, there were significant barriers to the development of glass tiles, included the high temperatures required to melt glass, and the complexities of mastering various annealing curves for glass.
