What is the best way to weld gold and sterling silver that has a
Rhodiumed white gold is not such a problem, simply solder and
re-rhodium. I like to polish off the old rhodium up to a visual
break, I've had problems with trying to feather it in.
Sterling is another matter. It will have an underplate of copper
and/or nickel, since rhodium doesn't stick to sterling. What you may
find after you solder is a blobby, blistery mess. You'll start to
polish only to reveal the differing underplates. And nickel will
often polish out with a decidedly raised edge (because its much
harder then the silver and copper), you may have to totally refinish
the whole piece.
Personally I don't see the point of rhodium on sterling, its not the
same color or luster as silver.
Some alternate ways of completing your rhodiumed sterling job...
silver charms...replace the rhodiumed jump ring with a fresh
sterling ring. Oh, and don't pickle very long, you may find it
copperplated. adding bails etc...use or make an eye tab, soft solder
in place sizing rings...file off all the plating before hand up to an
appropriate place on the design, tell your customer to expect a
change in appearance. OR be prepared to replate the item, a pain and
a lot to go through for a small fee
In the old days I would take on all comers, I thought that would
build my reputation for being able to fix anything. Finally I
realized that policy is a loser as far as running a business is
concerned. Sucks up time and all you really get is a load of headache
jobs. Its far more profitable to present yourself as an expert on
valuable items. I will occasionally accept such low end work as an
accommodation to a regular or potential customer, but I charge for
