I know there is a long article on this already available on Ganoksin
but I would like to hear how people manage with firescale and how
they do depletion gilding. I already use the de-natured
alcohol/borax mix and flux on all pieces but when making silver
boxes, they are repeatedly subject to the torch and firescale seems
to be inevitable!
I think I am doing the depletion gilding correctly but would love to
hear how others use this method on silver.
I gently (bushy flame) heat up the piece evenly until the first
obvious signs of oxidization appear, then I quench the piece in
clean pickle (citric acid), then I dry slightly and brush with brass
wire brush and finally I wash the piece with dishwasher soap and
warm water. I repeat this 6 + times. I think this is working but am
afraid of it coming back!
Also what I don’t quite understand is that if I want some areas of a
larger piece to have a high polish, certainly final finishing the
piece and then doing depletion will matte the high polished areas.
So do I then return and give those specific areas another polish
with rouge? Any help, insights, thoughts welcomed! Thanks
