ANODIZED ALUMINUM - It’s the ideal baking surface. Our ‘Safe-Seal’ anodizing process creates a safer, stronger baking pan. A durable, non-reactive finish that bakes a wider variety of recipes, including citrus-based and savory recipes. Freezer safe. HEATS & COOLS QUICKER - By reflecting heat, rather than absorbing heat, ProSeries cake pans reach baking temperatures faster. Even heating allows for the best possible rise. Once out of the oven, they cool quicker preventing over-baking. NO EXTRA METALS OR CHEMICAL COATINGS - Anodizing is not a coating. It is an environmentally-friendly process that contains no chemical additives, dyes, PTFE’s or PFOA’s. Nothing that can transfer, peel, flake or rust into your baking. BUILT BAKERY TOUGH - These are the same pans bakeries, commercial kitchens and baking enthusiasts around the world depend on every day for professional results. Lifetime warranty. Hand wash recommended. BAKE WITH CONFIDENCE - Fat Daddio’s ProSeries bakeware heats faster and cools quicker so your recipes turn out the way they should.
