The Upscale Prism cover is perfect for those who appreciate the extra sparkle of an embossed lid. The prism pattern on the metal lid is beautiful and practical as it camouflages scratches that inevitably come over time but never compromises high-quality performance. Made of natural aluminum that never rusts but evenly distributes the heat is what makes aluminum the superior choice for professional and home bakers alike. It's a pan you'll be proud to bring to gatherings. The lid and base are both oven-safe. Plus, the cover doubles as a baking sheet!
