Thread: Help ID this stone

I would be grateful for any help identifying this tone. It was never used with oil. It's a dark grey, very hard, smooth (high grit) and has a light brown "swirl" in the stone at one end. I've been going crazy trying to identify it.

It could be an Arkansas stone. It looks like it needs some lapping.

Can you lap an Arkansas stone with a norton silicon carbide lapping stone or would that mess up the norton? Also, what makes you think it's an Arkansas?

1+ can only agree on the statement

I don't see why you can't lap the stone with the Norton lapping plate, unless they say "don't try it on Arkansas stones". You can try sandpaper on a (really) flat surface if you are not sure.
I'm not sure why. The no 2 and 3 photos, sides and edges-corners, it look like non porous novaculite. Cutting marks are also not visible like most of the slate stones. Is it slow, and, can you make slurry on it? Touch it with a flashlight and see if light passes through, to see if it's translucent.

Ohh its still listed on the bay, right ?
Is it your auction ?
