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.
Peking glass
Peking glass (also known as Qianlong Glass or Tao Liao Ping) is a form of Chinese glassware that originated in 18th century Peking, China. Originally used in the fabrication of glass snuff bottles, Peking glass has since been appropriated for a number of uses and continues to be produced in China.
