NordicWare's top-rated Naturals®Bakeware collection is made of pure aluminum for superior heat conductivity and produces consistent evenly browned baked goods every time. These premium pans have a lifetime durability and will never rust. Encapsulated galvanized steel rims prevent warping. Creativity meets natural aluminum sustainability. Use & Care: 1. Before initial use and after subsequent uses, hand wash with warm, soapy water. Not recommended for dishwasher use, as discoloration will occur but will not affect baking properties. 2. Season pan with a solid or spray vegetable shortening before each baking use or line with parchment paper. 3. Scouring pads and metal utensils may scratch pan, but will not affect baking performance. 4. Aluminum is reactive to the acids in certain foods such as vinegar and tomato products which may darken, pit or corrode the pan. Product Details: Cooking Surface: L: 13.00 in. W: 16.00 in.
