Translucent colorless glass, bubbly with patches of highly iridescent film, badly cracked and chipped; cast and lathe-cut. Ground and polished rim retains two lathe-cut grooves on interior (5 mm apart), wall bends in and down to form a truncated ovoid body resting on a cavetto or concave profiled spindle base decorated by a lathe-cut boss with central point on the underside; the vertical handles at the rim no longer retain their thumb-rest although the curving finger rings are complete; the elaborate scroll work, typical of metal skyphoi, is preserved along the edge of the rim.
