Hi there,
First of all please forgive me as I am no chemist! I'm a jewelry artist and have recently started electroforming with copper. I've managed to produce some good pieces but I was wondering if there was any way to change the copper's appearance and make it less orange/pink. I googled around and came across a high school experiment using a copper penny and basically plating it with zinc to turn it silvery colored, and if heated, a gold color (brass alloy).
My question is whether using this method will work on my copper jewelry? I can't find anything anywhere that talks about using this method on anything other than pennies, and was wondering if this is because pennies are an alloy and therefore chemically different to pure copper. Or if the alloy is insignificant and this will still work on my copper jewelry?
Here's a link to the experiment if you weren't familiar with it already:
