Ancient Glass Blog of The Allaire Collection

The glass blowing revolutionized the Roman glass industry of the first century. It allowed, for the first-time, glass to be sold to the average Roman.  Also with blowing an object could be made much larger as well as quickly.  Before this glass was only a luxury item as rare as gold or precious stones. This was mainly caused by the time it took to make core-formed objects (45 minutes) or casting or cutting techniques (several days) and size and technology of furnaces.  Glass blowing is a process of forming an object quickly and in many different sizes and shape.  Simply, it is blowing air through a metal tube (blow pipe) into a mass of molten glass.  This short clip from Corning Museum of Glass by Bill Gudenrath explains it clearly (active link). Glass blowing was developed probably by Romans in Syria or Phoenicia (now the region of modern Lebanon) in 50 to 75 B.C.  If not discovered by the Romans it was certainly exploited by them throughout the Empire.
