The Demeyere Atlantis features a superconductive copper base. This Inductoseal base is made up of 7 layers (7-ply), with the copper core encased in stainless steel. Using TriplInduc technology, the base makes excellent contact with the induction plate, giving the Demeyere Atlantis up to 30% more efficiency when used on induction, allowing you to cook more energy-efficiently and save on your electricity bill. The Inductoseal base of the Demeyere Atlantis pan is so stable that you can seamlessly alternate between using the pan on induction and other heat sources. Are you cooking on induction but want to use the pan on gas for a while and later back on induction? No problem. The surface of the Atlantis pans has undergone an electrochemical Silvinox® treatment, making the stainless steel easy to clean and resistant to fingerprints and acidic foods. The pans remain silver-white, even after years of use.
