[TheForge] Cast iron history

[Phlip]

Anybody know the history of cast iron? When/where  it was first used, and
when it became popular and relatively inexpensive for cookware? Or, a
reference I could follow?

"When in doubt, heat it up and hit it with a hammer."
 Blacksmith's credo.

 If it walks like a duck, and quacks like a duck, it is probably not a
cat.

Never a horse that cain't be rode,
And never a rider who cain't be throwed....
