A ceramic ware produced at Iznik in Turkey from the 15th century. The clay body was covered with a white slip, providing a background for strong designs and bright colours. Under Suleiman the Magnificent (1520–60) the pottery flourished, producing dishes, ewers, lamps, and tiles, particularly for the mosques in Istanbul. Initially these were decorated with scrolls, arabesques, and foliage; later stylized flowers were introduced, particularly carnations and tulips. By the 17th century standards declined and decoration became lifeless and repetitive.
