Vessel

Swirled in dark streaks, this tiny pot looks like stormy water frozen in place.

This blown glass vessel of the Islamic period is Islamic, and dates to the 7th century. Glass that has been buried for centuries often takes on an iridescent surface as its outer layers weather, a change that is common in archaeological glass. Round-bodied jar with a short flared lip and a wide rim. Diagonal bands of dark gray and white twist around the body, with a faint rainbow sheen showing in the weathered surface. It is 1 inches wide, 1 deep and 1.5 high.

A small storm with a very steady base.
