 However, subsequent archaeological excavations in Kütahya have unearthed fragments of pots in the blue and white Iznik style that had been damaged during manufacture ('wasters') providing evidence that fritware pottery was produced in the town.The designs, materials and manufacturing technique appear to have been similar to that used in İznik.Kütahya is further from Istanbul with less easy access to the capital and was probably only a small pottery producing centre in the 16th century.
