English delftware is tin-glazed pottery made in the British Isles between about 1550 and the late 18th century. 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" or "galliware" and its makers "gallypotters" until the early 18th century; it was given the name delftware after the tin-glazed pottery from the Netherlands.[1][2]
Many everyday wares were made: tiles, mugs, drug jars, dishes, wine bottles, posset pots, salt pots, candlesticks, fuddling cups (that is, ale mugs joined in groups of three, four or five with connecting holes to confuse the drinker), puzzle jugs (similar to fuddling cups), barber's bowls, pill slabs, bleeding bowls, porringers and flower bricks. Humble undecorated items included chamberpots, colanders and small disposable ointment pots (gallipots), dispensed by apothecaries. Large decorative dishes, often called chargers, were popular, and included much of the most ambitious painting, often stretching the artists to the edge of their capabilities, and beyond.
