I’m interested in sweat soldering three pieces of sterling silver
onto a silver silver back plate - in other words, overlay. The pieces
are all flat. I have problems with the top pieces moving around after
the heat is applied. Perhaps I use too much flux, or my flux is too
wet, or I don’t dry it sufficiently. In any case, it happens.
For this particular piece I want to keep the gaps between the pieces
consistent. If they all three move relative to the backplate, that
But I don’t want them to move relative to each other.
So I was wondering if there is something I could use as a spacer
that would not get soldered down but also would not act as a
troublesome heat sink.
The only idea I have so far is to buy a sheet of Ti from RioGrande
and saw out 1/8" x 1/8" squares and place them between the pieces of
sterling to create and maintain a 1/8" gap. If the pieces start to
move under the heat I can use my pick to push them back together so
they are touching the Ti squares.
Any thoughts or better ideas?
