gold filled will melt at the temperature required to fire gold metal
clay…
you should be using 10 kt gold solder for attaching the parts plating
the soldering area with nickel, then gold or rhodium would solve the
greening problem, as would coating the back of the bracelet with a
sealant enamel- any of this requires an additional bench charge,
since the guy failed to tell you he couldn’t wear silver, yet bought
it in the first place. sealant is the cheapest way to go if you don’t
want to shuck out the cost of materials to repair if you made the
mistake of saying you would absorb the costs…of his failure to
inform you of his inability to wear certain metals… replacing the
pieces tu mentioned by fabricating with PMC/Art Clay is not as cost
effective as using the actual metals.
22kt gold pmc does not have coper added to alloy it…22kt yellow, or
coloured gold does, unless you pour your own…Sounds like a lot of
work to fix something he knew was going to react with his body
chemistry anyway.
I’m unclear as to where the battery is- in a watch maybe… but. the
battery is probably sealed in a stainless bezel, no? It is more
likely the guy can’t deal with copper given his body chemistry. knew
it and bought it anyway…so no silver is going to work except using
fine silver pmc, formed and perhaps cold connected onto the proposed
plated ends of your bracelet…
I would personally coat the thing with marine varnish or a sealant
available from jewelers supply houses and be done with it…too much
time for too little a return…since he failed to give you critical
about his reaction to silver… and bought it in the
first place.
