Super durable, lighter than cast iron and oh, that gorgeous unexpected blue. Perfect for cooling baked goods—or glazing donuts and roasting vegetables when paired with a sheet pan—our quarter sheet rack 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 rack raises food for better air circulation and has a gridded design to prevent small items from falling through. Our slate blue cooking and cooling rack features a silicone-based non-stick coating that ensures easy release and quick cleanup.
