I have one or two of his anvils as well. Very handy.
Wayne: The charcoal powder might work as it pure carbon. I've never used it , but give it a try, as it can't hurt anything.
I only used the foodgrade bone meal as I had a gallon can of it. The bonemeal that is used as fertilizer will work too.

The old mix for pack hardening ( case hardening) was bone charcoal and leather. this was packed in a container and heated to temp then container and all was quenched. The packs burning or smoldering kept oxygen out so very little scale formed when done right. For knifes to case harden a length of pipe with 2 caps and a small hole drilled in the caps. screw on cap on fill with the mix push blade in fill full and cap snugly. Heat to temp and soak for while then quench in oil or water depending on material. This process makes a mess when quenched as the vents let guench into the mix making a muddy slop.
i have one that i made when my buddy still had a forge back in the late 90s, looks like the one nyfirefighter posted, even with the twisted handle
Casenite/Kasenit (sodium ferrocyanide) might do as well for case hardening. Only case hardens the outer what, 5-10 mils though? Tho I would think the bone meal etc. do about the same. No machinist but know some things
