Copper bowl question
I just purchased a copper bowl from a thrift store. It was pretty oxidized, but I could see that on the bottom it said: "1801 Paul Revere". It seemed fairly heavy and I assumed that it would be solid copper. However, after I started cleaning it up at home I realized that it looks like a copper finish over brass or something.
Is this common in these "beater bowls" or whatever they're called? (It looks like a kitchen bowl that is made to be used for whipping egg whites -has the brass ring and everything.)
Any thoughts on this? Thank you, Amy
