This greenish grey cylindrical bottle has an angular shoulder and a short flared neck. The decoration consists of ridged vertical ribs twisted slightly counter clockwise outside the mold. The object is intact. The surface is partially weathered, resulting in whitish milky patina.
Both the shape of the vessel and the type of opening seem to point to an early period of the Islamic glass production, probably before the eleventh century and more likely in the tenth.
Mold blowing, in which glass is blown in molds with patterns, was a very common means of decorating glass vessels throughout the Islamic period. The pattern molds of the Islamic periods were made from bronze or copper alloy and shaped like beakers. The most common decorative pattern used was the vertical ribbing seen on this vessel.
Bottles of this kind were believed to have held oily substances, and the decoration was designed to make them easier to hold.Login to view price
