Isn't being "cast" meaning it is solid? So, there is no fluidity. Must
be trick question on a final exam!

Glass is solid, yet its considered a "slow liquid"

Maybe why all those old lathes wont hold tolerance anymore. The cast
iron has flowed a bit.

I realize you're joking, but the creep properties of cast iron, combined
with the structural design of a lathe, doesn't lend itself to significant
distortions from "flow." Now, if the bed of a lathe is under stress from
being poorly aligned over a period of years or decades, that might be
different.
