In the I Love lucy episode Little Ricky Learns to Play the Drums we see that a set of copper cookware has appeared in the kitchen where there used to be shelving. The copper cookware set looks like the traditional French style copper pots widely favored by chefs. Top of the line ranges such as Mauviel are much desired for their traditional style and craftsmanship and for the excellent heat conducting properties of copper when used over direct heat such as a gas flame (BTW copper bottom pots do not work on ceramic stovetops as far as I know).
Vintage sets of copper cookware can easily be found on eBay but some are only suitable as decorative items when any of the lining has worn away inside the pot. As decor hanging on the kitchen wall as seen in Lucy’s kitchen they give off a warm copper glow and lend vintage charm for the holiday season.
