Zwischengoldglas

Type of decorated glassware

Zwischengoldglas, is a type of decorated glassware in which a design in gold leaf is created on a glass vessel, then sealed under another precisely-fitting glass vessel, which is then bonded to the first piece with cement. The use of adhesive rather than fusing by heat the two layers of glass is what distinguishes the process in English from the gold glass technique, which was popular in the late Roman Empire, although in German "zwischengoldglas" is often used for both.
