The container for pack carburizing can be iron, steel, ceramic, it doesn't
matter as long as it can stand the heat without cracking or distortion.
Some gunsmiths often use terra cotta pots from a plant nursery when color
case casing.

I wonder if you could answer one question: In the description
of case hardening from the Machinery's Handbook above, it is
suggested that a cast or wrought iron box be used in the carbonizing
process. As is the usual case for old literature such as this, the
iron box is mentioned in an offhand way, as though everyone has some
laying around. As you know, wrought iron stock is effectively
equivalent to unobtainium these days. Is there any reason that wrought
or cast iron was preferred back when that book was written? Was it
just what was most commonly available back then, or is there some
advantage to it over, say, steel?
Thanks again.
Of course, acquiring the hooves and horns will be another problem! :-)
