Thanks to Calphalon's new nonstick technology, this professional hard-anodized aluminum cookware allows you to cook with little or no oil – and cleans up with almost no effort. The hard-anodized aluminum pots and pans feature durable cooking surfaces coated with four interlocking nonstick layers, so even the stickiest foods release easily.  Exteriors are infused with an advanced release polymer, so the pieces clean up in a hurry – inside and out.  Other impressive features:  stay-cool stainless steel handles, domed tempered-glass lids, and a lifetime guarantee.  Pans are oven-safe to 500°F.  Hand wash.
