I remelt my Argentium scraps without fuss into ingots weekly.
Just don’t wait too long after it is a mercury-like liquid to do
Use a crucible only for argentium, remember to break in your
crucible with borax when it is new. Also, the ingot mould preparation
is very important.
Ingot making is a skill of it’s own. I am tempted to do a video on
the topic but time is tight these days.
Best of luck.
