... the argenitum backplate always slumps. Is anyone else having this problem?
As indicated in all the major resources for Argentium
Silver, AS will slump if it is over-heated. Since backplates are
particularly prone to this kind of difficulty it is important to
support the plate from underneath – as in laying it on a soldering
brick or whatever – when you are doing this kind of work. Thing to
watch out for include: the thinner the plate the greater the tendency
to slump; the hotter your flame the greater the tendency to slump;
and the higher your working temperatures the more important the use
If you follow these basic guidelines and use a little inventiveness
you won’t have slumping issues, especially if you are using the
So, if your AS is slumping you are almost certainly over-heating it.
This could be because you’re using a hot-running torch, particularly
thin gauge plate, too bright a work light so you’re not seeing the
metal colors, or some combination thereof. With proper control of
your tools and workpiece it is quite easy to eliminate over-heating
and the corresponding slumping issues.
I believe this has all been discussed before here, on Cythia’s site
if I’m not mistaken, and certainly on my blog.
