English Delftware English delftware is tin-glazed pottery made in the British Isles between about 1550 and the late 1700s. The main centres of production were London, Bristol and Liverpool with smaller centres at Wincanton, Glasgow and Dublin.
English tin-glazed pottery was called "galleyware" and its makers "gallypotters" until the early 18th century; it was given the name delftware after the popular tin-glazed pottery from the Netherlands.
