probably Iran
later 12th century AD
honey-coloured glass, blown, tooled and trailed
29 x 17cm
This is one of the largest intact pieces of Islamic glass. The destruction wrought by the Mongols in the early 13th century put an end to the manufacture of glass in Iran for four centuries or more.
The flask has a flattened base with a pronounced kick and a pontil mark.
