I am puzzled by your unsuccessful experience making AS silver
granules. None of the AS granules I have made collapse no matter what
home method I tried. I torch the AS silver wires on a solderite board
because the granules turn out bright and shiny. On a charcoal board
the granules come out a dull white so I prefer not to use charcoal.
Searching for some explanation for your experience, I thought maybe
the charcoal-fired granules could collapse, but when I tried them
this morning, they too did not collapse.
I have used the Stern-Leach created granules along with my
"homemade" ones. Both work equally well and neither collapse.
Perhaps you could elaborate on your method. Standard sterling silver
granules will collapse as you describe, so I wonder if the silver
wire you used actually is Argentium silver. Hope to hear more from
