Try a Froogle search for " black patina on copper " , many choices.

I need to turn a bit of copper foil black. I have less than 1 square foot
to treat. Paint isn't an option. Anyone know of a good way to do this?
Google search wasn't real productive. I am wondering if any of the
Birchwood gun stuff would work?? I tried using a sulphur paste, it
tarnished it, but not black...

Thanks,
