This is probably a stupid question with an obvious answer, but I’d
like to ask it anyway. On a few occasions, I have attempted to
solder gold details onto my sterling jewellery, sometimes with
success and other times not. I haveused both 9k and 14k pieces.
Unfortunately, I have not made a note (mental or otherwise) whether
one works better than the other, and experimenting is too expensive.
The problem is, that when it doesn’t work, the gold actually
disappears intothe sterling silver, but not only that. It actually
seems to eat a hole in the silver too! It’s difficult to describe,
but the last time I tried it, I was soldering small silver balls
onto a silver setting I’d made (faux granulation), but decided to
add some gold ones as a contrast. I noticed that the gold ones were
disappearing into the silver as quickly as they were being soldered.
When I looped it, on the back of the piece, the gold had "eaten"
great big holes in the silver setting!!!
Can anyone explain what is going on, and perhaps what I need to do
to avoid this. I know people use Keum Boo as an alternative method,
but you don’t always want the decoration to be flat and level with
with the surface of the sterling.
