I used 18v 1.7amps. However, a 9 volt battery should suffice. A six volt battery from radio shack might work, but no guarantees. Any lower and it probably won't work. However, the half reaction for copper is 0.34v.
Cu2+ (aq)+2e− → Cu (s)
In a perfect system, you might only need .68 volts to plate. However, my knowledge regarding electric potentials is a bit limited. It may have something to do with current too....
hi : If I want to tinplate a copper vessel, can I do the same procedure ? In this case I've to connect the vessel right?
