you know I used to try to soldering that way, I was told you could do it
that way to solder silver rings that have turquoise in them. Tried it and
after it was all over with realized some things are’nt meant to be done
the " easy " way.When ever I’ve got to either do a repair or a sizing
,etc. I take the pearl or turquoise out. Now I’ve used other types of heat
sinks to do sizing on rings that have say emeralds and even amythest in
them , but I personally feel certian things should be done a certian way
due to my own experiances. If you can get away with doing it the other way
more power to ya. Keep it Real…Matt the Catt
