Oxidizing Copper
Hey does anyone know a quick way to oxidize copper to its blue form (rather than etch it as FeCl3 would)? The way that FeCL3 is used to rust iron?

Birchwood Casey sells brass black that works well on copper, too. Comes out almost like blued steel.
forgot to say, the copper has to have any oxide taken off, or it will be spotty.Last edited by mikeyr; 12-13-2009 at 05:58 PM. Reason: B.F.
