.....I would love to get the formula for your red gold. Will
it fuse, as in bezels or links to weave chain?
Glad to oblige. 22k is just 22 parts AU, 2 parts CU (same as
Krugerrand, actually). 18k colored to match is 18 parts AU, 3
parts CU, 1 part AG. Yes, the 22k fuses with no problem at all,
the 18k is a little fussier, but works. I’ve generally been
soldering the 18 and fusing the 22.

Right! That may be part of the problem, I’ve been filing AFTER
annealing. Will try the other way and see what happens. Also
like your idea of soldering on an iron wire; will try that also.
I’ve also had “little bitty” ingots that were too small to roll or
draw. Nice idea. And, I think the next batch will have a few %
zinc added; I’ve seen several references in the literature to zinc
improving ductility of gold alloys. I guess I took your name in
vain, John! Sorry 'bout that.
Thanks, everyone, for the ideas. I’ll let you know how they work
