A suggestion: if you coat the tip of the frasier in ivory bar soap
before you heat it to anneal/harden it, you’ll have much less oxide
to clean up.
It’s not a perfect flux, but it does make a noticeable difference
What I normally do is get the bar wet, and wash my hands with it.
Then rub the chasing punches that I’m making in the wet soap left on
the bar. That’s about the right consistency. And it gets my hands
