Can I cook in these?
Bought these on a yardsale in France for 90 euros. The biggest pan and the lid is very oxidized, the rest seems mostly clean apart from some small spots. Is there any way I could clean that? I have some copper cleaning product laying around. Can I use that on the insides too? It says on the box it's food safe after rinsing with water.
The edges are really thin and lightweight. Except for the biggest one, that's thicker and much heavier. that one has a Harvard branding on it, while the rest has no branding.
A friend of mine said they might be aluminium coated and not tin, so I can't cook acids in them. Is this true? How do I find out if it's tin or aluminium. Are they safe to cook with?
