Pans in this collection are constructed with vacuum-pressure cast aluminum, which is superior to stamped in both shape and thickness. Tradition features the Dupont Autograph 2 Gourmet Non-Stick 3-layer nonstick interior and 2-layer exterior surfaces to protect against sticking and burning. The nonstick surface is designed never to chip, crack, blister, bubble or peel and is guaranteed never to warp. Tradition is exceptionally easy to clean and facilitates fat-free cooking. Wooden handles allow safe and easy transporting of pans, and stay cool on the stovetop so no potholders are necessary, all for your convenience.
