Copper tarnishing


#1

I have been asked to make a bracelet using copper, rather than my
usual gold. Is there a treatment I can apply to stop the copper
tarnishing?

Hey Pat; It’s a little mercenary, but being as how we’re goldsmiths,
shouldn’t we be working in gold? Try to sell your customer on 10k red
gold. It’s is very bright and coppery looking, doesn’t tarnish, and
is exactly as effective as pure copper in the treatment of arthritis.
Which is to say, not at all. I’ve done a couple of bracs in this
material and while it’s a little finicky to cast and roll, it looks
great. Good luck, Ken.

Super trick for removing tarnish from copper!  Ketchup!

Why would you want to use ketchup when vinegar and salt is much less
expensive and messy? Louise @lgillin1

Hi Ken! Great idea to use 10K red gold for copper color! But if it’s
being soldered to silver and gold parts, it’s important to know the
melting point, or more specifically, the melting point it will give
in the interface with other metals. Don’t want a melt-down :o)…!
People who work a lot in precious metal mokume would probably have
something to tell us on this matter…

Try the following, to not have your base metal bracelet (or ring,
etc.) leave a residue on your skin. Dip it in some patina
solution (like Jax Black) which contains selenious acid. It will
turn black. Rub off most of the black with fine pumice (leave a
little more “color” on the inside of bracelet). Brighten up the
outside with a polishing cloth now and then to keep it shiney. I
think you’ll find it will no longer leave that green or whatever
mark on bare skin. At least, it has worked great over a period of
months for my nickel-silver ring which I wear a lot,through
dish-washing and everything. Good luck! Judy Bjorkman
