Bismuth, huh? Well, it’s the next heavier element after lead, decays so slowly
that it might as well not be radioactive (half-life of 19*10^18 years), is the
only non-toxic heavy metal (aside from the radioactivity, but you probably get
that much radiation standing under direct sunlight) and combines easily with
lead/tin/iron/cadmium...but its melting point is 520.52F, which is well higher
than the point where ABS will have melted to a smoldering heap of slag. You’re
probably using a tin/bismuth alloy with a pinch of lead. I ran across one
supplier who has a bismuth alloy that
actually melts at 158F (70C). Geez, you could melt that stuff in a hot-pot
double-boiler (not something that you’re likely to find for sale, but I did
build one for customizing action figures).
