BTW, something to keep in mind, if you haven't done this, is that
potter's
clay makes an effective wrap for slow carburizing. Just roll some out
fairly
thin (maybe 3/16" or 1/4" at most) with a rolling pin and wrap the part,
with some carburizing material, like a burrito or a dumpling.
Next time I'm food shopping I'll get some burritos and give this a try.
No, seriously, I take your meaning and it sounds like an excellent idea.
I was wondering about using some sort of ceramic pot instead of a steel
or iron box. I never thought of just encasing the part in potter's clay
along with the carburizing material. Sounds much easier to do than baking
a special air-tight ceramic box.
I forgot to mention that you should wrap the part in paper first, to keep
the clay from touching it while it's still wet. And, if you're just
heat-treating, rather than carburizing, the paper is enough.
If you're inclined to be obsessive, lay a strip of wood lathe or something
similar on each side of the clay when you're rolling it out, for screeds.
That way you'll get a uniform thickness of clay.
Have fun.
