LaunchPad: Ancient GlassmakingThe Roman Mold-Blown Technique

Beginning in the 1st century A.D., Roman glassmakers determined that blown-glass vessels could be mass-produced using molds. This method of production, which allowed glass workshops to produce multiples of popular designs, was employed for centuries thereafter in the Roman and Byzantine empires. In this video, the Roman Glassmakers, Mark Taylor and Robert Hill, demonstrate the ancient Roman method of producing a mold-blown glass jug, similar to the Art Institute of Chicago's Pilgrim Jug, using a clay mold.
