Origins of Glass

Ms. Prinkey

The discovery of glass 5000 BC

Natural glass has existed since the beginnings of time, formed when certain types of rocks melt as a result of high-temperature phenomena such as volcanic eruptions, lightning strikes or the impact of meteorites, and then cool and solidify rapidly.

A craft is born 16th century BC

The oldest fragments of glass vases date back to the 16th century.

Hollow glass production was also evolving around this time.

Early hollow glass production 1500 BC

After 1500 BC, Egyptian craftsmen are known to have begun developing a method for producing glass pots by dipping a core mould of compacted sand into molten glass and then turning the mould so that molten glass adhered to it.

Glass Blowing 27 BC-AD 14

A major breakthrough in glassmaking was the discovery of glassblowing some time between 27 BC and AD 14, attributed to Syrian craftsmen from the Sidon-Babylon area.

The long thin metal tube used in the blowing process has changed very little since then. In the last century BC, the ancient Romans then began blowing glass inside moulds, greatly increasing the variety of shapes possible for hollow glass items.

The Roman connection AD 100

The Romans also did much to spread glassmaking technology.

With its conquests, trade relations, road building, and effective political and economical administration, the Roman Empire created the conditions for the flourishing of glassworks across western Europe and the Mediterranean.

Romans were the first to use glass for architectural purposes.

Because they were building roads, trading goods, and had an effective political administration, they helped spread the use of glass making and techniques.
