These saucepans offer enduring performance and durability that withstand the rigors of intensive kitchen use. Guaranteed not to chip, peel, or crack, the tough non-stick surface makes clean up a breeze. They are manufactured using vacuum pressure casting to produce a professional weight piece of aluminum cookware that will not warp; superior to stamped cookware in both shape and thickness. Three layers of nonstick interior and exterior coating ensure healthful cooking with less oil and protect foods from sticking and burning.
