I frequently scour flea markets for old cast iron, but lately I've been keeping an eye out for copper as well. Finally, I found a piece! But now I realize that I'm actually not quite sure how to go about cleaning it up for use.
The inside is tinned and dark, but not uniform. There was some gunk in the bottom that a thorough wash with hot water, Dawn, and a little white vinegar seems to have mostly taken care of, but I'm not sure whether what remains is unevenness in the tin itself or gunk that hasn't dislodged. I don't want to really scrub at it or use anything too abrasive inside because of the tin, but maybe that's necessary the first time?
I've attached a few pictures to give a better idea. If you look closely, a portion of the bottom has a definitely pinkish tinge, but it doesn't look as though the copper has fully come through anywhere. Is that enough to require retinning? Also, there's an odd grey smudge on the outside. I'm not worried about it aesthetically, but wondered if it might be a sign that perhaps it's not solid copper, and maybe just a thin coating? I rather doubt it, as the edge is copper all around, but thought it might be worth asking.
Finally, if anyone knows anything about "BD Co New York" copper cookware, I'd love to hear it!
I am brand new to copper, so I do apologize if any of this sounds ridiculous. (:
