Well, it maybe they ought to call it POP metal. ;)
Actually it's called _pot metal_ as it's "cast" or poured into a form which
is then referred to as a _casting_. When I was a kid I couldn't understand
what the heck "pop metal or pot metal" was. I didn't know what cast metal
was either but I sure did know what "cast iron" pans were.
