The neck of this ninth or tenth-century blue flask is decorated with vertical cut facets and horizontal grooves, while the body has linear patterns carried out on the wheel. The shape is clearly Islamic, and represents a hallmark of Iranian glass production from the eighth to the twelth and thirteenth centuries, while the decoration is based on Sasanian models. Vessels such as this were made in large quantities both for the domestic and the export market and were traded as far east as China and Japan.
