Islamic, ca. 10th to 12th century CE. A beautiful cobalt blue, pattern-molded glass bowl decorated with an intricate honeycomb pattern across the exterior walls and standing upon a circular base comprised of coiled glass. Adding to the inherent beauty of the elaborately decorated cobalt blue glass is the glossy fiery polish which imbues the surface with an almost liquid-like appearance. An extremely attractive piece of Islamic pattern molded cobalt blue glass! Size: 3.5" in diameter x 1.875" H (8.9 cm x 4.8 cm)
Mold-made glass is fascinating, because the artisan had to envision, formulate, and then cast a design. Scholars believe that most of the molds were made of bronze, thus involving a metalworker as well. According to Stefano Carboni and Qamar Adamjee of the Department of Islamic Art at The Metropolitan Museum of Art, "Most medieval examples were created in so-called full-size molds, though no examples of these survive. Molten glass at the end of a blowpipe was inserted into a two-part hinged mold in the shape of the vessel and then inflated. The pattern, carved on the interior walls of the mold, was impressed in relief on the glass upon inflation; the mold was opened to release the object, which was then finished with a rim, foot, or handle as necessary. Such a mold was called full-size, as no changes were made to the size or shape of the glass object after it was removed from the mold. Popular patterns include vertical ribbing or fluting, honeycomb and chevron designs, a variety of geometric and vegetal motifs, and sometimes inscriptions."
