ROMAN MOSAIC GLASS BOWL WITH BLUE BASE Ca. AD 100 - 300 A Roman mosaic blue glass bowl, made through an intense and difficult process. The deep blue base has been set with pre-formed composite white and yellow mosaic glass. Following this stage, the interior of the bowl and the rim rotary would have been polished, and the exterior fire-polished, creating a smoother surface. An item such as this would have been prohibitively expense for all but the wealthiest of the Roman elite. For similar see: The Metropolitan Museum of Art, Accession Number: 91.1.1400.
