Thank you guys it's good to hear that I didn't do too much damage. For those sparse "shiny spots" you see in the pictures, should I assume that I took off the hardened metal there, or just the bluing?
Twistedwilllow, the anvil weights around 107 lbs (48,5 kgs). It belongs to my wife, until a couple of generations ago most families here (a hilly area in northern Italy) were involved to some extent in agricolture and farming, and brazier and anvil were quite standard household items used to fix livestock tools and the likes.
Unfortunately, the skill to use this equipment is usually lost. As for the tests, the anvil seems to ring fine to me, but I'm 100% unexperienced. I mean, it definetely doesn't ring dead.
