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).

Thanks guys,
This will do nicely. I’ve used theis alloy before, but had no idea where to buy
more.
