We collaborated with the legendary coppersmiths at Ruffoni to create our exclusive Thermo-Clad™ Copper series. Designed to bring the joys of cooking with premium copper to home cooks, the bonded pans combine beautiful mirror-finish copper with the practical maintenance of stainless steel. This saucepan offers maximum heat responsiveness on the stovetop, giving you more control when simmering sauces and soups.

• Thermo-Clad technology bonds thick, mirror-polished copper to a thin interior layer of 18/10 stainless steel.
• Made from 1.2mm-gauge copper.
• Solid copper is the fastest heat conductor, ensuring quick, efficient and uniform heating with precise temperature control.
• Stainless-steel lining is nonreactive and ensures ease of use and maintenance for a lifetime.
• Ergonomic stay-cool stainless-steel handle provides a comfortable grip and maximum control.
• Exclusive double-wall insulated lid stays cool and will keep food warm for up to 90 minutes.
• Oven safe to 450°F.
• Made by Ruffoni exclusively for Williams Sonoma.
