Swiss Diamond 10pc Cookware set features a revolutionary non-stick surface using diamond crystals to form a virtually indestructible non-stick cooking surface. This set includes both 1.4qt and 2.2qt saucepans with vented tempered clear glass lids, both 8″ and 10″ fry pans, a 3.2qt sautepan with a vented tempered clear glass lid, which also fits the 10″ fry pan and an 8.5qt stockpot with vented lid as well. The non-stick surface will not peel, crack or blister and provides perfect heat distribution for cooking meals containing less fat. The pans are made from a 6mm thick pressure cast aluminum which has a perfectly flat base for use on all ceramic, gas and electric cook tops. The stay cool handles are ergonomically designed and is safe to use in an oven up to 500deg F. Metal utensil safe.
