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. We've configured this essential set to include a 3-qt. covered sauté pan and 1-qt. covered saucepan for everything from simmering sauces and cooking grains to sautéing, browning, searing and braising.
