Excellent. Not constant; and perhaps not even linear?

If you run across a thermal conductivity table for steel
from say 0 to 1000 C let us know. From that graph we
should be able to calculate what Rex felt when he put the
red hot (1500 F?) end of the 1 inch bar into cold water.

Better yet, if some metal or material has an even more
pronounced thermal conductivity function it would make
a great party trick.
