RRuff has given a good idea about plating using old, copper-filled
pickle. I use this plating technique in a number of ways but I need
to warn you about using it.
I use a different pickle so I don’t know how this would work with
vinegar and salt, but the fumes given off while the plating is going
on will scorch your lungs if you breathe it. I use a pH Minus
(sodium bisulphate) pickle heated in a crockpot and I learned the
hard way. If you have any kind of ventilation system available, I
advise you to use it in this process.
Another problem I’ve had with this type of plating is that the layer
of copper going onto your piece is very thin. It is very easy to rub
it right back off in the finish work so be very careful. Maybe I’ve
been doing something wrong and , if so I’d like to hear about it. I
have a lot to learn in this pursuit.
