I'm getting ready to make a run to the scrap yard, but I have a couple
of questions.

!. I have a pile of stuff that is definitely yellow brass, and
another pile that is definitely red bronze, but there is a third pile
that isn't as red as the bronze and not as yellow as the brass. It
there a simple way to identify whether something is brass or bronze?

2. I have a lot of copper wire that was salvaged from a fire. It is
bare, but it is black (either from soot or burned insulation). Is
there a simple way to clean it up a bit? It would be great if the
chlorine or muriatic acid from the wife's pool supplies could do the
trick.

Thanks,
Ed
