Portmeirion Pottery is made from a high fired, dense, very white earthenware that is particularly resistant to chipping and breaking. This ware is oven proof to 170°C/340°F and is microwave, dishwasher and freezer safe.
Portmeirion bakeware/ovenware is made from a strong, white stoneware which is resistant to temperature changes and is able to withstand oven temperatures up to 200°C/390°F. The ovenware is distinguished by a ribbed, slightly rough finish on the base, which makes it less liable to slip, it was founded in 1960 by the legendary pottery designer Susan Williams-Ellis and her husband Euan Cooper-Willis. Susan sadly passed away in November 2007 but her philosophy of creating collections that are not only beautiful but also functional and affordable lives on at Portmeirion.
