Does anyone have any strong feelings one way or another as to
whether boric acid/alcohol, Prips or commercial products like
Cupronil compare in terms of reducing firescale? Does one seem to
work better with gold vs. silver?
I have been using boric acid/alcohol for 20 years and find it the
easiest for gold, but I hate it on silver, I almost quit working
with silver until I discovered Cupronil, it takes a little longer to
apply but it works great. I have a few designs that I high polish
before soldering bezels, and all I have to do is a quick touchup
after using Cupronil.
Also I might be crazy (and some out there would agree) but I think
there is a difference between the denatured alcohol from the jewelry
supply/drug stores vs the hardware store. I have been told there is
none, but it burns different, it smells different and it seems to
have an oily residue. So for all you chemist out there what’s the
answer, maybe I’ve inhaled to many fumes, at least with the boric
acid around I don’t have roaches in my shop.
Best to all,
