The Seljuk dynasty that ruled Iran, Iraq, Asia Minor, and Syria in the 12th and 13th centuries found substitutes for porcelain, and the Iranian cities of Rayy and Kāshān became centers for this white ware.
Another fine Seljuk type was Mina’i ware, an enamel-overglaze pottery that, in its delicacy, imitated illuminated manuscripts. Kāshān potters, after the 13th-century Mongol conquests, used green glazes influenced by Chinese celadons. Cobalt-blue glazes appeared in Iran in the 9th century but later fell out of use. They were taken up again in the 14th to the 18th century in response to the popularity of blue-and-white ware with Chinese and European clients.
