We teamed up with the stainless-steel cookware innovators at Napa Valley-based Hestan to create our signature Thermo-Clad™ Stainless-Steel collection. Available only at Williams Sonoma, Thermo-Clad is crafted in Italy to our precise specifications using an exclusive aluminum alloy that provides up to 35% better thermal conductivity than other aluminum-clad metal cookware on the market. This set includes a covered pan and insert that combine to form a double boiler.
