The Mauviel M'héritage Collection is a combination of two powerful and traditional materials, copper and stainless steel. This blend of materials energizes the pleasure of cooking. The 1.5 mm straight edged copper allows for unsurpassed heat conductivity and control, and the stainless steel interior is ideal for all daily cooking needs. The cast stainless steel "stay cool" handles have stainless steel rivets and give the pans an aesthetic, modern look. The Mauviel M'héritage collection represents the total experience and heritage of Mauviel 1830, and is used by professionals and household cooks throughout the world.
