Copper Pans and Bowls

Pans and bowls made from copper have been used for centuries in kitchens throughout Europe. This material is one of the most efficient heat conductors but should not be subjected to extreme temperatures, as these can damage the tin lining. These days most copper pans are lined with stainless steel. Untinned copper bowls must be cleaned prior to every use with salt and vinegar to remove traces of verdigris [a green deposit that develops on the surface].
