Glassmaking: history and techniques (article) | Khan Academy
In about 25 B.C.E. glassmakers began to create decorative vessels, such as this cup, by blowing glass into a mold with incised designs. Mold fragments of stone, clay, bronze, and plaster have survived from antiquity. The earliest makers of molds for glassware may have been ceramists familiar with constructing molds for clay vessels.
