Iznik ceramic articles and tiles are traditionally made of soft clay. In the Early Middle Ages techniques for colour glazing were used in the production of tiles, which were further developed and perfected. Tiles with inscriptions under the glazing started to be made in the 16th century. Floral designs and inscribed ribbons were the predominant patterns. In the mid-16th century, the Islamic ceramic masters started to integrate red-coloured reliefs under the glazing of their articles which were especially rigid.  Nowadays they are highly valued across the world.
These tiles were usually used as part of the interior decoration of mosques, mausoleums, palaces, pavilions, fountains, imarets and libraries.
