Condition
Intact. Some iridescence.
Description
Hemispherical bowl with vertical, ground rim. Relief rings start at 1.4 cm below the rim. Three pairs of double rings are separated by two equidistant rows of single rings, forming seven bands, 0.7 cm wide, in total. A small disk is at the center of the bottom. The rings and the small disk are made of the same amber-colored glass as the body, and they are only covered on the surface with a thin layer of white glass.
Comments and Comparanda
Both the interior and exterior present dense rows of parallel scratches, remains of grinding and polishing. It has been plausibly proposed that the two-colored vessel was cast, and then the outer layer was removed with wheel-cutting, creating the perfectly arranged and executed pattern of relief rings. The vessel is extremely rare, unexpectedly thin, if indeed molded. There is another similar, white bowl formerly in the Sangiorgi Collection, today at the Corning Museum of Glass (Whitehouse, David B. 2001. Roman Glass in the Corning Museum of Glass, vol. 2. Corning, NY: Corning Museum of Glass., p. 16, no. 2), and a third, fragmentary emerald-green bowl from Magdalensberg, Austria (Czurda-Ruth, Barbara. 1979. Die Römischen Gläser von Magdalensberg. Kärntner Museumsschriften 65; Archäologische Forschungen zu den Grabungen auf dem Magdalensberg 6. Klagenfurt: Landesmuseum für Kärnten., p. 20, no. 8, plate 1:8).
