Glassmaking Technique: Gold Glass

– [voiceover] Gold glass is
made by sealing gold foil between two layers of glass. The process begins with the
creation of a base disk. Glass is inflated at
the end of a blow pipe and the bottom of the bubble is flattened. After cooling, a scratch
is made along the side. The scratched area is
heated until a crack forms to separate the top from the base. Adhesive is painted on the
base and gold foil is applied. A sharp tool is used to create decorative patterns in the gold. When the decoration is complete the disk is placed in an annealing oven. A second glass bubble is inflated and held upward to form a spheroid. The glass is reheated
and carefully lowered onto the decorated base disk. The two parts are reheated
so that they’re fully fused and placed into an annealing oven to cool. The vessel is scratched,
heated, and cracked off to form the rim. Finally, a stone is
used to smooth the rim.
