The new craft is inspired by the Chinese blue and white, best known to the Ottomans through the Persian Timurid pottery center at Kashan. The fritware paste with a high content of siliceous rocks does not make it possible to obtain the hardness of a porcelain. The decorations of the early Iznik ceramics juxtapose the vegetal patterns in the Chinese taste and the arabesques of the Ottoman metalwork. This mixed style is named rumi-hatayi.
Blue is obtained by cobalt but the concentration of underglaze pigment is poorly controlled, generating a too intense color comparable to earlier phases of the Chinese blue and white. It will take about two decades for bright blue to be made in Iznik. Until about 1520 cobalt blue remains the only available color.
On October 24 in London, Sotheby's sells a charger from the Baba Nakkas period with a wide everted rim, lot 134 estimated £ 300K. It is 45 cm in diameter and 8 cm deep.
This piece has a documented provenance over more than half a century but had never been published. It joins an extremely limited population of four dishes of similar technique and dimensions, all of them preserved in museums. The rumi-hatayi Baba Nakkas ceramics is also known in other shapes : jars, candlesticks, flasks.
A rumi-hatayi bowl from the next phase circa 1510 was sold for £ 1.43M including premium by Christie's on April 10, 2014 over a lower estimate of £ 300K.
