Fused glass is made by taking a number of pieces of glass and putting them into a kiln, where they are melted together to form a single piece.
The history of fused glass began with the ancient Mesopotamians in the second millennium B.C.
The Phoenicians developed a fused glass technique that involved using disks of glass that were heated in furnaces.
The fused glass method was further developed by the ancient Greeks and Romans, who heated the glass around core vessels to produce mosaic forms.
Fused glass fell out of use when glass blowing became widely used by the Romans in the first millennium B.C.
The fused glass technique was revived by members of the Pate de Verre movement in France in the 1870s. It continued to evolve in the 1950s when a group of Americans used kilns to turn recycled material into fused glass.
