The Egyptians had important uses for the glass: they kept it for the royalty and used it to copy precious stones. Such copies were regarded as original gems.

Sometime around the year 50 occurred the most important glass’ application evolution, when a lucky handcrafter discovered that a bubble was formed when submerging an end of a hollow metal tube into the melted glass and then blowing through the other end. This man’s genius allowed him to apply this to create beautiful objects and containers.

This progress increased glass' popularity and was later known as blown glass. It stopped being exclusive for luxurious pieces and started competing with ceramics and metals that, at the time, were preferred materials for containers' production.
