A local woman is selling a set of copper cookware. I went to check them out for possible purchase as she said didn't know much about them. They are copper with iron handles. There are no identifying marks except that some (all?) of the handles/helper handles have a number stamped into them. The rivets are a silver colored metal, and the interior has the concentric circle/ spun metal look, so I'm guessing they are stainless lined as the tin I'm familiar with is smoother. The pots also had/have lacquer on them. Do "better" copper cookware companies use lacquer? I didn't measure, but my guess is they are around 1.5- 2mm walls, give or take. She has had them for over 10 years, mostly as display, though some have been cooked in.
We did use a weak magnet to see if it would be attracted to the lining, but it wasn't. Is there any simple test to determine if a lining is stainless or tin? Like putting vinegar in it or something simple like that?
Thanks for you help! It will be interesting to learn what you know and see if anyone can ID them. :)
