 As Miletus had a long history as a pottery producing centre, it was erroneously assumed that the pottery was produced locally and it became known as 'Miletus ware'.It is now believed that İznik was the main centre for the production of 'Miletus ware' with smaller quantities being produced at Kütahya and Akçaalan.The excavations have not provided a clear date for the pottery but it is assumed to belong to the 15th century.
