History of glass
The history of glass-making dates back to at least 3600 years ago in Mesopotamia. However, they may have been producing second-rate copies of glass objects from Egypt, where this complex craft originated. Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or Egypt. The earliest known glass objects, of the mid second millennium BC, were beads, perhaps initially created as the accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreous material made by a process similar to glazing. Glass products remained a luxury until the disasters that overtook the late Bronze Age civilizations seemingly brought glass-making to a halt.
Ancient Greek art
Although glass was made in Cyprus by the 9th century BC, and was considerably developed by the end of the period, there are only a few survivals of glasswork from before the Greco-Roman period that show the artistic quality of the best work. Most survivals are small perfume bottles, in fancy coloured "feathered" styles similar to other Mediterranean glass. Hellenistic glass became cheaper and accessible to a wider population.
