Two Islamic Nishapur Glazed Pottery Bowls

A collection of two small pottery bowls with polychrome central figurative decorations, matching size and similar conical form. These bowls are identified as Nishapur ware circa 10th century (in nowadays Iran). They were stoneware (possibly buffware) and covered with opaque white glaze. Both were lovely decorated with a central human figure within an outer border. One is predominantly yellow, an imitation of luster ware. The figure appears holding two branches, a possible harvest scene. It is surrounded with a thin blue circle with writings on the outer rim. The other one is predominantly turquoise blue featuring a figure holding a basket collecting between two trees (possible olive trees). An outer border with scrolling pattern is rather wide, also showcases the bright blue color.
Upon close inspections, both bowls appear intact but shows a lot of wear. In many places, there were hairlines, crackles and scattered losses of surface glaze, revealing a reddish clay body underneath.
