Oil slate actually, Kevin!
Sham I was thinking of it as a thuringian by its slurry.
I don't think I'm 100% on that but thats why.

Johnny J, yours looks like the first one I posted.
I'm not...

Looks like a Thuringian to me, Benjamin!

Sure thing. Just look at the dragon's tongue. Perfectly slate.

The slate on the back of the newer coticules is not really useless,
it just often has impurities.
One vendor in germany sells it on its own.
It does hone. you just never know what kind of grain...

It really does look like a coticule to me, Smythe!
Maybe an extraordinary soft kind?

A purple slurry from the slate side indicates that as well.

Yep, I guess the middle range between 1000 and 5000
is the hard part when it comes to naturals.

well, after color correction with mine as the benchmark it looks like this:

.... looks like candy fudge!
where did you find it?

Its too hard for a coticule.
Just tried to raise some slurry, but to no avail.
You get the slurry of the bout but the hone gives nothing off.
Works well to use it with coti slurry though.

You also lapped the sides!
Well then it might just be the same as mine.

You hit a pipeline, LOL
Don't think mine will do the same. I've been lapping off quite something cause it came pretty dished. The surface is dry and not very porous actually.

Crichton of course!...

Mine doesn't absorb any water.

No David, not until now.
I use it occasionally.
Between setting the bevel and starting to polish its quite nice.

Yes, it is a finishing stone.
Very fine and very slow.

Hi Mudkipz!
Well to me it also looks like an Arkansas.
Beautiful one, too. They do make a slurry when you try hard enough
and a nice addition to your setup.

That is a beauty!
Never seen before - neither here nor anywhere else. Thank you!

Oh glad you brought this on.
Got sidetracked this morning,

Why not!?! Anything we're not completely sure about.

I'm curious about the ones beenpickin posted.
Didn't Oldengaerde have one like that in the "not a piece of wood" thread? :hmmm:

Thank you!
Even the case is similar but honesty I doubt it is a Charnley forest.
Mine has no veins or other irregular structure and I guess once your's is lapped, it will look quite plain as well....

:yYAY!
Thank you! (Yesterday I wasn't sure whether anybody would ever post any thing to this thread)

Keep them coming! :tu

ndw76, it looks volcanic to me. Basalt maybe?

Unresolved square mysteries gathering!
If you're a proud proprietor of a natural hone you can't find a name for.
Come and shovel them in!
Anything non carborundum you can show us,
will make you...
