In the 1940s it was noticed that archaeological materials from the Ottoman period in Hungary contained faience from Anatolia. However, Iznik and Kütahya ware, Persian faience, Chinese porcelain and celadon also occur, the last two principally in the vilayet centres of Buda and Eger. Most Oriental ceramics pieces from the Ottoman period are artefacts of modest quality for everyday use. The Kütahya ware, the Persian faience and the Chinese porcelain all served one purpose: coffee drinking. However, material from earlier times includes ornamental vessels and can be linked to the royal court and ecclesiastical circles.
