Calphalon Contemporary Hard-Anodized Aluminum Nonstick Cookware, Deep Skillet, 13-inch, Black Heavy-gauge aluminum construction ensures even heating and is hard-anodized for durability. It also makes it dishwasher-safe. Interior includes three layers of nonstick coating - two layers provide durability and the third layer offers easy release performance. The long, brushed stainless steel handles are designed to stay cool on the stovetop. Pans and covers are also oven safe, making it ideal for finishing a gourmet dish. The rich, elegant exterior color is not a surface coating, but is a result of a change the aluminum undergoes during hard-anodization, for a fully-infused, dishwasher safe color that won't chip, crack or peel. The nonstick surface of the saute pan means you can cook healthier using less fat, with effortless cleanup. Comes with Calphalon's full lifetime warranty.
