smithlabs! what is a Bismuth?

Metal that will melt in hot water. For amusement purposes of course.

Rubber molds can be used. A lot of model Rail Road accessories are cast from Bismuth.

I didn't know that, has that been around a long time?

I had a friend casting Model Rail Road stuff in the 1970s. :)

that sounds right but for some reason I thought that stuff was around in the 40s?

Could have been 1940s, that was just when I ran across it. :)
