Iridescent Glass Vessel Fragments
Iridescent glass vessel fragments 8th–9th centuries, Fustat (medieval Cairo), Egypt Scratch-engraved glass Kelsey Museum of Archaeology, 1970.3.514 and 1970.3.515
These two glass vessel fragments share a rich aubergine color, and both are ornamented through an engraving or scratching technique. While this decorative process antedates the advent of Islam in Egypt, the deep blue-purple color was particularly popular among Muslim craftsmen. The designs were scratched into the surface of the dark colored glass with a pointed tool, resulting in light-colored geometric striations. This type of freehand "sketching" technique in glass allows for a great flexibility of designs, including crystalline patterns, floral motifs, and cloud bands.
