Glazed with durable non-porous enamel, Le Creuset stoneware is ideal for oven, microwave and grill use. The tough craze-free glaze will not absorb flavors when cooking, storing or freezing. In a variety of colors, the Stoneware is designed to match and complement the cast iron pieces. Nothing could be more perfect for multi-purpose use of beautiful presentations than Le Creuset Stoneware. Our high quality stoneware moves smoothly from the refrigerator or freezer to the microwave, and it's ideal for use in the oven up to 260°C / 500°F or under the broiler.
