Core Formed Amphora 400 BC Mediterranean
Early hollow glass production began around 1500 BC.
Egyptian craftsmen developed a method for producing glassware by dipping a core mold of compacted sand or clay into molten glass then turning the mold so the glass adhered to it.
The glass covered mold would then be rolled on a slab of polished stone or marble in order to shape, smooth and decorate it.
Few people were allowed to make glass which was kept a carefully guarded secret and only a sect of priests were allowed to produce it.
Only Pharaohs, high priests and nobles were even allowed to possess it.
Notice the tooled ridges on the Amphora to the left. This pattern is still practiced extensively in modern studios using optic molds.
