Hi folks. Longtime lurker, first time poster. I’m not a jeweler, but
I play around at various forms of metal working and I have a question
that jewlers might be able to answer.
Someone told me that it was an old jewler’s trick to solder coin
silver using coin silver filings and flux – that is, using the same
material for both the filler and the pieces being joined. Apparently
the filings melt just before the larger pieces. Is anyone here
familiar with this technique?
Can someone direct me to a written discussion of it in a book (or
books)? Does it work with materials other than silver? And can
anyone explain why the filings would melt before the pieces being
joined? Is it just a question of arriving at the melting temperature
a few seconds sooner?
Thanks very much.
