Hi Friends,
A couple of soldering related postings this morning have mentioned
the use of non-silver solders (i.e. lead/tin soft solders). While it
might be possible to get away with this for a short while in jewelry,
it will eventually come back to bite you. I feel there are a couple
problems using it in jewelry work:
-
It isn’t a hard solder. Its little more than putting glue on. The
temperature is so low, the grain structure of the metal doesn’t open
up to accept the solder, so it just “globs” on the surface. This
might be okay for non-jewelry related work , but jewelry is often
subjected to more stress and the solder joint(s) may fail. If and
when you have to re-repair the joint, you will have a terrible time
getting the contaminating solder cleaned up. -
The solder is actually corrosive to silver at “normal” easy
soldering temperatures. It will literally eat the silver away if it
is heated too high at some later time… like on a subsequent
repair.
I learned this the hard way, when I was first starting out. This was
during my trial and error (mostly error) period. I didn’t have any
mentors or an awesome resource like Orchid to advise me. If you find
yourself backed into a corner where you are seriously considering
using soft solder for jewelry work, I’d suggest using epoxy
instead… at least its not corrosive to the metal and can be removed
later with solvent, if needed. The holding power might even be better
than soft solder.
P.S. I like all the cold connection suggestions made to John about
his buckle dilemma. That thought hadn’t occurred to me, and it just
goes to illustrate all the wonderful people we have participating in
this community!
All the best,
Dave
