The production of high quality "fritware" (the Encylopaedia Brittanica gives it as "soft paste porcelain" or Cini used to be in Iznik (see other gallery). There it went into decline and gradually production was transferred to KŁtahya (where at another industry they also make porcelain proper). KŁtahya ware used to have characteristics of its own, but ever more the classical Iznik patterns and colours are used. Over the last tens of years great improvements have been made in quality and design. One can see and buy plates, tiles, bowls et cetera all over the country, particularly in the tourist areas. I prefer to do my buying in KŁtahya itself. The local ceramics museum now houses a good collection of some old pieces and examples of modern work, often a gift by their producers.
I understand that the man on this portrait designed (or re-designed from classical originals) many of the patterns that have been used on KŁtahya ware during a greater part of the 20th century.
