Viking Professional cookware features five-ply bonded construction, with alternating layers of aluminum and stainless steel to optimize heat distribution. The 18/10 stainless steel cooking surface is non-reactive. The magnetic stainless steel exterior is induction compatible and features a satin finish. Cut rims enhance the fit of the lids, and stainless steel lids retain heat and moisture. Ergonomic stainless steel handles are securely attached with rivets and stay cooler on the stovetop.
