I do appreciate the advice. After more than a third of my life in
jewelry work and not so much of it is silver work, I do realize a
"better way" had to exist on that deep firescale in sterling. The
common advice is to cover it by heating and pickling, as building up
a layer for reticulation; or, by abrasive methods. I opted for
"getting it gone" and the abrasive route. I have used the auto body
compounds you suggest on autos, not on silver. Thanks, I have some
of this material and will try it.
That is, I will try it the next time I forget to firecoat the item
or simply overheat it! : )Actually, we have all made such mistakes
and fortunately some will say so and from that come solutions to the
problem. I do appreciate that very much in a fellow craftsperson.
This stuff sits on a shelf in the garage...simply did not think to
try it in metal work. Thanks.
