Glass weight
Translucent turquoise blue.
Solid cylindrical shape; flat top; convex side; bottom slightly concave with projecting pontil scar at center.
Intact, but one small surface chip and crack in side; few bubbles; dulling, creamy weathering, and brilliant iridescence.
This unusual object may be seen as a glass weight. The brilliant turquoise color resembles that of some early Roman glass but it probably belongs to the early Islamic period.
