Uncomplicated Story Of Glass
Naturally occurring glass in a form of obsidian was used even by Stone Age societies whose members utilized it to produce sharp cutting tools. However, the archaeological evidence suggests that the first true glass was made somewhere in north coastal Syria, Mesopotamia or Old Kingdom Egypt. Egypt, with its preserving climate, is a place where we can find a lot of early glass items. Glass beads are thought to be the earliest man-made glass products and date back to 3500 BC.

A rapid growth in glass making techniques is assigned to the area of Late Bronze.
