Glassmaking Technique: Free-Blown Glass

In the mid-first century B.C., glass makers around Jerusalem discovered they could inflate glass into a bubble at the end of a tube. This new glassblowing technique revolutionized the glass industry, allowing vessels to be made quickly and more cheaply, and glassware began to replace clay vessels for household use. Watch a demonstration of this ancient method in this video, featuring footage from the Corning Museum of Glass.
