Cobalt- and turquoise-glazed tiles of different shapes covered the walls of Ilkhanid palaces, mosques, and mausoleums. The turquoise hexagonal tiles of this arrangement bear conventional circular floral designs molded in relief, while the star tiles are glazed in cobalt and decorated with Chinese lotuses, a motif that entered Iranian art during this period. The deep contours of these forms, together with the iridescence of their glazes, makes the patterns visible even under a monochrome glazing.
