There have been several posts that mentioned cracking argentium. I
am familiar with how it cracks or breaks during fusing, when support
was obviously insufficient. But cracking much later ( as in the
example given of a dragonfly having cracked in the maker’s hand at a
show) - this is something I’d like to know more about.
Is there any way to observe in a newly finished piece the fault that
will eventually cause the cracking? Or do you only suspect it, based
on how the piece was handled during fusing or brazing?
I ask because I am constructing fused argentium rings, and at times,
in order to fuse-on certain elements, I have supported the shanks (
with pieces of solderite and rolled up chunks of “ceramic blanket”)
at various angles, i.e. not flat on the charcoal.
I do switch to soldering in the final stages. I don’t move my pieces
until they are cool. But I’d like to be able to somehow inspect
these rings to be quite sure they are structurally sound. Anyone
know how I could do this?
