These frying pans, part of the M'tradition of Mauviel copper cookware, are true gems and built to last more than a lifetime [put them in your will to please the next cooking generation]. Constructed of solid copper and lined with hand-brushed nontoxic tin for safe cooking, they are ready for heavy duty use. The heavy weight of these fry pans can be attributed to the 3 to 3.5mm thickness of the metal. Handles in the Cupretam line are made of heavy, rounded, smooth cast iron. Three sturdy rivets affix the handle to the skillet.
Copper is such a joy to cook with. Its exceptional ability to conduct heat makes it the most responsive of all the metals. Moderate heat should always be used with tinned copper. High heat will destroy the tinning. If you have never cooked in copper, it's time to treat yourself.
