This bowl was mold-blown from greenish translucent glass, which was then decorated with cut-work relief patterns. The body of the bowl is encircled by an upper row of eight protruding cut circular forms and a lower rank of six cut circular protrusions. A single circular protrusion larger than those on the body forms the bowl's base in place of a foot. Each of the protruding circles on the body has its corners planed off and from the interior of the bowl each shows as a round circle of light. The protruding circles come out about 10mm from the wall of the cup. The mouth of the bowl is about 4mm thick. Fragments of this type of glass work have been discovered on Okinoshima Island of Japan, and this indicates the very wide range of distribution of Persian glass.
