Does anyone know where to find fine-grit carborundum grain for
soldering? I’m having the hardest time finding a supplier.
My first experience with it (which was most pleasurable indeed) was
during my apprenticeship with a local jeweler, where I fell IN LOVE
with the stuff. She had a very small stash of it which she guards
carefully because she, too, can’t seem to find a source to
replenish what she has.
I read (via Wikipedia (usual Wikipedia disclaimer applies…)) that
"It occurs in nature as the extremely rare mineral moissanite (SiC
aka silicon carbide)." Given its rarity, might that be why I’m not
finding it in this form? --But then that kind of doesn’t compute
because, as with many other rare minerals, its use is consistently
widespread in everything else from general industry abrasives, to car
brakes, electronics and more.
So, any known sources of the stuff? Anybody want to share their
stash? (I will pay.) --I also wouldn’t mind having/finding one of
those small cups/holders that you use it in…
