Glass Frit: Coloured Glass Melted, Quenched in Water and Ground

Frit is glass that has been melted, quenched and broken into grains. Pour melted coloured glass into water: it shatters into grains that grind easily, and sieved into grades they colour fused and slumped glass. Egyptian blue, the oldest frit, coloured a tomb painting about 2900 BC. The picture: frit grains.
