Mystery plating on silver


#1
 DeDe have you had silver rings to size with a plating that
bubbles up when you solder and how can jewelers deal with this
at one time silver was just silver now it has plating on it and
makes it hard for the jeweler to do his work and keep the
customer happy well i need to get off my soap box!!!! this is
to all the list  thank jack 

I believe the plating is nickle and is used to prevent
oxidation. Back in the 70’s a friend and I were selling gold
plated silver beer can tabs (no longer exist, my kids have never
seen one) to frat houses and such. After we got a batch back due
to oxidation, we sent a couple hundred to a professional plating
company (Tannury, they plate cross pens etc) to avoid this
problem. They told us that silver, if plated, must be plated with
nickle because its the only one that is not porous and thus will
prevent oxidation. After the nickle then they applied the gold
plating. I myself have never really been able to get a super
bright nickle plated finish on a previously nickle plated silver
item, it comes out frosty and must be polished. I usually return
these undone to customers, more trouble than they are worth. Mark

Right on, Mark. I have run into problems with this bubbling
effect also. It’s a real nightmare to fix (ie. sanding,
polishing, replating etc.) My understanding is that the nickle
plating was done also to give the silver a harder surface. I’ve
also seen gold plated base metal rings that were stamped 14k-
with this “crap” on them. I remember the old beer tabs too. In
fact, I have a mold on one and still occasionally sell one. Ken

Ken -I once read that sterling is plated with Nickel before it
is gold plated to prevent the copper from coming through the gold
finish after awhile and changing the gold color–making it too
red? Have I got this right? Sandra/ElegantBee

From what I was told, it is more a matter of what best bonds
with what metal- strike with copper plate over the sterling or
base metal, then nickel plate, then gold.
