Glassmaking Technique: Mold-Blown Glass


Mold-blown glass is made by blowing hot glass into a mold made of clay, wood, or metal. Glassmakers create decorative vessels by using a mold with incised designs. Mold fragments of stone, clay, bronze, and plaster have survived from antiquity. Watch a demonstration of this method in this video, featuring footage from the Corning Museum of Glass.
