Glass has been produced for millennia, initially being an admired material crafted by only a few gifted artisans. The earliest glass artifacts were discovered in Mesopotamia from around 2500 BC, though materials mimicking glass were used even earlier in Egypt. True glass production began around 1500 BC in ancient Egypt and Mesopotamia. The Greeks and Romans further advanced glassmaking techniques, with the Romans pioneering glass blowing which allowed for intricate patterns and mass production of vessels. Sadigh Gallery has a collection of ancient Roman glass artifacts including mosaics, beads and vessels available at wholesale prices.
