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.
Hebron glass
The glass industry in Hebron was established during Roman rule in Palestine (63 BCE-330 CE). As the ancient Phoenician glass industry shrank from the exposed cities along the eastern Mediterranean coastline, the industry migrated inland, to Hebron in particular. Glass artifacts from Hebron dating to the 1st and 2nd centuries have been found, and are on exhibit as part of the Drake Collection. Stained glass windows made of Hebron glass dating to the 12th century are found in the structure built over the Cave of Machpelah, which served as a church during the Crusader era in Palestine. Another example of stained glass windows produced in Hebron are those adorning the Dome of the Rock in the Old City of Jerusalem.
