I have once again gotten myself into a “pickle” accepting
something to repair for a friend. It is an inexpensive sterling
ring with sentimental value. When I removed the fauceted "stones"
before doing the soldering I found there is a packing material
behind them to raise them. The material used in the previous
packing is white. Ummm… I haven’t a clue what to use to
replace this but know there are some suggestions out there…
Your experience and assistance are most appreciated.
