Super durable, lighter than cast iron and oh, that gorgeous unexpected blue. This six-piece set is part of our exclusive bakeware collection that takes its cue from professional kitchens. Made of carbon steel—an alloy of 99% iron and 1% carbon that's nearly indestructible—the baking sheets and pans heat quickly and maintain consistent temperatures for perfectly browned and crisped foods. Double layers of silicone-based non-stick coating ensure easy release and quick cleanup. A great housewarming or engagement gift, the set includes two baking sheets, one 12-cup muffin pan, square cake pan, loaf pan and cooling rack.
