These may the ultimate, non-stick baking pans. Because they're made entirely of premium, food-grade silicone, they're oven, freezer, microware, and dishwasher safe, as well as being non-stick, stain-resistant and flexible. Baked goods release easily and quickly from the pans, and of course, they won't rust and they can't break or get dented. Oven-safe to 500 degrees F
