A fine Islamic Glass Beaker, Mamluk Period, ca. 13th - 14th century CE

This elegant hand-blown beaker features a conical body tapering to a thickened base, where a double layer of glass forms a distinctive “doughnut” ring. The glass exhibits a subtle yellow-green hue and retains iridescent weathering typical of excavated Islamic glass. On this example, there are still trace remains of a band of rectangles, and there is faint evidence of finer decoration that can be seen under magnification.  

Glass beakers of this type were characteristic of Islamic glass production during the Ayyubid and Mamluk periods, particularly from Syrian and later Egyptian workshops. The technique of enameling and gilding—introduced in the 12th century—reached its zenith during the 13th century under Mamluk rule. Colored opaque enamels and gold were applied to the surface in intricate floral, vegetal, and Arabic calligraphic designs, then fired in a kiln to fuse the decoration.

Though often compared to contemporary Venetian glass, Islamic enameled glass is distinguished by its iconography and technical approach. The widespread archaeological recovery of similar fragments suggests these vessels were not exclusive to elite patrons but produced for broader commercial markets.  Such beakers were primarily used as drinking vessels, likely for wine and water, as indicated in period literature and visual depictions. The uniformity in decoration, color, and form among surviving examples has led to the hypothesis that these were produced in nested sets for storage and transport, rather than being differentiated by function, as is the case with modern glassware.
