The terms of ishkornaya or ishkor ware are used in the western archaeological literature. They relate to the alkaline glazes produced from plant ashes. This technique is still used nowadays. The archaeological material from Paykend provides the samples with opaque or transparent alkaline glaze from the 9th—10th century and later, from Timurid and post-Timurid period. The first ones are produced in Paykend’s pottery workshop. The following are from the oasis region. They are characterized by the presence of the siliceous slip between the earthenware body and the glaze. This observation remains to be confi rmed by laboratory tests.
