More durable than our traditional metal bakeware, ceramic nonstick delivers high release performance and is PFOA & PTFE free. Pans feature an elegant two-tone design made of premium materials. They are easy to maintain with a scratch resistant interior and can be safely placed in the dishwasher, although hand washing is recommended for best results. Calphalon Signature Nonstick Bakeware has a full-lifetime warranty.
