Bottle with a Honeycomb Pattern, anonymous, c. 1100 - c. 1200
The early Islamic glass workers refined the techniques they had inherited from their predecessors: Roman, Byzantine, and Sasanian craftsmen. They also often adopted the forms. This bottle with a honeycomb pattern, for instance, is comparable to Sasanian examples (Iranian dynasty, 3rd–7th century). Sasanian bottles, however, were made of cut glass, while this medieval vessel is mould-blown.
