A beautifully durable combination of copper and stainless steel, this sauce pan allows for unsurpassed heat conductivity and the enduring style that comes with Mauviel's traditional craftsmanship. A natural patina can develop over time, though a vinegar-salt solution or lemon and salt rub will maintain the eye-catching mirror-polish finish. Mauviel M'150c2 Copper 2.5-Quart Saucepan and Lid-Home
