Calphalon Tri-Ply Copper unites centuries-old culinary tradition with distinctive style. Featuring graceful curves and a stunning combination of expertly finished, tri-bonded metals, this new collection is as beautiful as it is hard-working. A brushed copper exterior and aluminum inner core combine for superior conductivity (the best that there is) and precise cooking control for spectacular results. Fine-satin, brushed stainless steel interior won't react to foods and won't tarnish or change colors even when cooking acidic foods like tomato sauce. Other features include flared rims for easy pouring, well-riveted, curved handles that stay cool to the touch during stovetop use and stainless steel lids that trap steam, heat and flavors. All Tri-Ply Copper cookware is oven- and broiler-safe. Handwash and dry thoroughly to avoid any spots. This 10-pc. set includes: 8-in. Omelette Pan, 10-in. Omelette Pan, 1.5-qt.
