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?

Here is a place hope this helps www.sciencecompany.com/patinas/patinaformulias.html#17

Try this one: Patina Formulas for Brass, Bronze and Copper

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.

Thanks Mike. Once again you come through to help me oxidize metal.
