Le Creuset’s 4pc. Heritage bakeware set is made of stoneware, which ensures excellent heat distribution for uniform browning, and the nearly nonstick glazed interior easily releases food. The glaze is non-porous, non-reactive, scratch-resistant and resists stains. The pieces have unmatched thermal resistance for temperatures -9F to 500F and are freezer, oven, microwave, broiler and dishwasher safe. Includes a 9” loaf pan, 9” pie dish, 3qt. square baking dish, and a 1.7qt. oval baking dish.
