These small cast bowls are modeled in shape on Roman silverware and Arretine pottery. Likewise, the brilliant emerald green color appears to be an innovation of the Roman glass industry itself. This was probably based in Italy, although examples of such bowls, either in mosaic glass or in monochrome versions of both translucent and opaque glass, are found thoroughout the Roman world.
