I'm confused, why would you not just heat treat and the temper this anvil? In my experience it would have saved you a lot of time and end with a much better result. Unless, of course, this was a mild steel that you started with, and if so I hope you have at least learned to use the right steel for the project you are working on at the moment.
I didn't know the origin of the sledge head, I just picked it up in a lot with other hammer heads. It must have been a mallet made from mild steel, I could not get it to harden. I did not check hardenability ahead of time because steel mallets are a fairly uncommon specialty use tool----so I just didn't expect it. No harm done, just gave me the chance to show a technique for case hardening.
Roughly 80% charcoal powder + 20% sodium carbonate (washing powder) , then you add a binder so that it holds its shape when it dries. I just use plain white flour, it works well because it is also a carbon source like the charcoal. The amount of binder is not critical, I usually add a lot----anywhere from 25-50% added to the weight of the charcoal/carbonate mix
Keep these coming, They are awesome!
Thanks, I appreciate the encouragement! I'm hoping to put out a new video next week.

You're welcome!
