I tried to solder the end caps on a woven bracelet using some paste
solder for silver (which flows at 430 F, 221 C). Never having done
this before, I had no way of knowing when it was reaching the
appropriate temperature. After heating for 10-15 seconds with my
torch, a flame (about 1" tall) appeared, coming out of the end cap
and lots of white smoke. After a few more seconds, this created a
burnt, black residue over the end of the chain as it enters the end
cap. So I’m thinking, obviously – I over heated it.
I have been able to clean the outside part of the chain with
abrasion, however, this doesn’t work on the interior part of the
woven chain that I cannot access. I’ve tried pickling for a long
time and my ionic cleaner but nothing has removed enough of it. I
don’t have an ultrasonic cleaner but would gladly buy one if it
would solve my problem. Any ideas??
