Very little mention has been made on this forum about un-soldering.
While either fusing or soldering will join 2 or more parts, it is
common in jewelry making to need to un-solder various components.
Improper alignment, solder which flows too far between 2 wires or
parts, or even a change in design may mean parts have to be heated
with a torch and either moved or removed.
While Argentium sterling does have many virtues, primarily in the
fusing realm, trying to un-fuse or un-solder parts can be
catastrophic with Argentium. Separating two wires that have been
soldered often means a broken wire. Moving parts into final alignment
before solder flows can again lead to a fractured part. It is this
"hot short" quality of Argentium sterling which causes many
While the germanium is the "magic" ingredient which gives Argentium
sterling its fusing and fire-scale free properties, I am told by
professional metallurgists that too much germanium in the sterling
causes the fragility at heat, or "hot short" problems. Less
percentage of germanium, the metallurgists say, will still keep the
fire scale to a minimum, still allow for good fusing characteristics,
and no problems with metal brittleness when hot.
Why not look for a high-tech sterling which contains germanium, but
in a smaller percentage, which will avoid the "hot short" problems of
