Islamic Glazed Pottery Bowl Nishapur Ware

An earthware pottery bowl supported on a foot ring decorated with white slip and dark brown and red paint. This type of bowl is typically identified as Nishapur ware circa 10-11th century (in nowadays Nishapur Iran). They were mostly a buffware type that was covered with opaque white glaze, on which further decoration was made. This bowl features a lovely form and was painted in dark brown and red, with a medallion with a floral-shaped cross in the center well. This may refer to "the cross of heaven", one of oldest symbols. From the center, there are six radiating motifs, each coupled with two shapes, that appear to be Kufic inspired. The exterior rim was simply decorated with scroll pattern in the same bicolor. It is noticeable that the opaque white glaze has a distinctive lemon-yellow tint, indicating a special glazed technique that was used to create such an effect (for reference of the yellow stain type of ware, see chapter 8 Ware with yellow stain black page 212-228 in book "Nishapur Pottery of the Early Islamic Period" by Charlie K. Wilkinson.
Upon close inspections and also under UV light, the bowl appears structurally intact, without noticeable cracks or losses, and not restored from fragment. There are expected wear with some slip chipped off the age and mineral deposit spots on the bottom of the bowl as shown.
