I'm wondering how to pickle a copper and silver bracelet.... wont
the copper pickle attach copper onto the silver? and putting the
copper in the silver pickle will contaminate the pickle....
Thanks, Im fairly new to jewelry and love this site for all
everyones and help!
Don’t worry, it won’t happen unless the bracelet touches something
made of iron or steel (steel contain iron).
Sterling silver is a mixture of silver and copper. When you heat it,
the copper oxidises and turns black or dark grey. The pickle
dissolves the copper oxide away to leave a very thin layer of pure
silver, but then the pickle contains a solution of copper sulphate.
If you place a gold or silver item in pickle containing copper
sulphate, nothing happens as long as it doesn’t touch anything
containing iron. But if it does touch iron it causes an electrolytic
reaction that deposits the copper in the copper sulphate onto the
gold or silver.
So, as long as it doesn’t touch anything containing iron, the
electrolytic reaction doesn’t occur and the copper remains in
