What is the best way to protect sterling silver from
discolouring/firescale when firing it with PMC? I exclusively use
Art Clay 650 or PMC3 so that I can fire it with a butane torch, but
have been reluctant to mix sterling and PMC because I am worried
about ruining a piece if I damage the sterling. I have read all the
info I can find about anti-firescale, but this forum provides so much
that I am thoroughly confused! I need a simple,
inexpensive solution to the problem as I do not have a need for large
quantities. Would painting the sterling with a mixture of borax(?)
and denatured alcohol suffice?
Christmas is coming and I expect there will be no Orchid for a few
days over the holiday - I will miss my daily fix!
Orchid is not resting this year
Best to all
