I've been using the Argentium sterling and am familiar with the
- which does burn off with subsequent heating or can easily be
removed with bristle disks.
However, In some of my earliest pieces, I did notice what appeared
to be firescale - a mottled stain that wasn't easily removed. This
seemed to be most common adjacent to the base of a bezel. At that
time I was using paste flux (Handy) which really facilitated the
solder flow. The paste fluxes in general had been recommended for use
In my research on the use of Argentium I had read that "some" paste
fluxes could stain Argentium sterling. I concluded (right or wrong)
that Handy was one of the paste fluxes I'd read about though I was
unable to verify the brands from the literature.
I decided to use another recommended flux.
F Flux powder from Thessco in England was very highly regarded by
Trevor (see below) who went through quite some effort to obtain it
but when I found that buying the F Flux powder (500 grams) would run
$200 with shipping and courier charge to Phoenix I ordered the
My-T-Flux from Rio, as it had been well rated.
I haven't seen the stain since I've been using My-T-Flux. (Knock on
wood, cross my fingers, hold my tongue just right)
My thanks to Peter Johns for his development of this wonderful
Though I'm still learning about working in Argentium sterling, I
offer many thanks and much appreciation to the following for
considerable and support regarding its use:
And to the Orchid forum, Ganoksin, Hanuman, Charles and Ton and all
their support crew I owe a continuing debt of gratitude for making
such sharing possible.
