Petrographic Study of Islamic potteries of Shahr-e Belgheys, Northern Khorasan Province

In the present paper, we have tried to study the mineralogy of ten pieces of the glazed potteries of Islamic era were discovered during a systematic archaeological survey on the Shahr-e Belgheys (Esfarāyen). For better understanding of potteries inside structural characteristics Petrographic thin sections and microscopic polarization were prepared. In the all petrographic sections composition of microcrystals were similar and only one piece (code 216) has represented a heterogeneous texture, but in terms of mineralogy all samples were shared a similar component indicating that the potteries would have been made from the same clay with local origin. Pottery sample (code 216) with a different geological composition may be assumed to have been a piece of a vessel was imported to the area
