Persia, Ca. 10th-11th century AD An amber glazed pottery bowl of a deep hemispherical-shaped body rising from a ring foot. From the 9th century onwards, distinctive Islamic ceramic styles, often involving glazed and/or incised decoration developed and spread across the Islamic world and beyond; Islamic ceramics also had an important influence on pottery production in Italy and in the Byzantine empire. This piece has been precisely dated by means of a Thermo Luminescence analysis carried out by Ralf Kotalla, an independent German Laboratory. The samples collected date the piece to the period reflected in its style, whilst also showing no modern trace elements. The TL certificate with its full report will accompany this lot.Size: L:70mm / W:160mm ; 600gProvenance: Property of a West London gentleman; previously in a collection formed on the UK/International art market in the 1980s.
