Layering
The layers allow even heat flow, and durability. The aluminum conducts heat well in the inner layers, but is not desirable on the outside because it corrodes and comes off in the food. Stainless steel protects the food and the cookware itself. Stainless steel also contains iron which makes it good for magnetic induction stoves.

Warp-Resistant Bottoms The special design of the bottom of each our pots provides extra strength and rigidity that will always prevent warping. The pans stay flat and hug the burner for maximum heating efficiency during the entire cooking process. All pans (not lids) are oven safe up to 350°. There is no need to ever use under the broiler.
The construction of both the 5-ply and
7-ply sets allows you to stack cook.
