DURABLE SQUARE FRYING PAN: The 9.5 inch Copper pan is made of copper and non-stick ceramic. The quality copper is used to provide durability so that the saute pan can be used for extended periods of cook time. The non stick surface is very slick, so food doesn't stick while cooking. Broil fish, fry meat, bacon, eggs, omelets, bake chicken, desserts, or whip cream. Unique square design gives up to 25% more room to cook vs. ordinary round pans.
