From Iznik. 16th or 17th century.

An example of the pure white ground on which the multi-color design (stylised leaves, flowers and blossoms) is depicted. These designs were drawn by the artists of the Topkapı Sarayı workshop and sent to the potters at Iznik for transfer to the tile panels and plates, which were not only used in the mosques and palaces of the Ottoman Empire, but were exported all over Europe.

İznik work, named after the town in western Anatolia where it was made, is a decorated ceramic that was produced from the last quarter of the 15th century until the end of the 17th century. İznik town was an established centre for the production of simple earthenware pottery with an underglaze decoration when in the last quarter of the 15th century, craftsmen in the town began to manufacture high quality tiles and pottery with a fritware body (frit being added to clay to reduce its fusion temperature), painted with cobalt blue under a colourless lead glaze. During the 16th century the decoration gradually changed in style, becoming looser and more flowing. Additional colours were introduced. Initially turquoise was combined with the dark shade of cobalt blue and then the pastel shades of sage green and pale purple were added. Finally, in the middle of the 16th century, a very characteristic bole red replaced the purple and a bright emerald green replaced the sage green.
