Thread: unknown monster

Today in the mail:
An unknown monster hone from my brother.








Since he's quite a brain it should be worth lapping.
Its a bit rough for a bench stone and a bit heavy for a hand held, LOL (1300 g / ~3 lb)
Yet have to ask him what it is exactly, but I think its some kind of a thuringian. (He lives 60km south of the old mines)

That was my thought at first glance going by the color. Hard to gauge the surface from the photos. Once you lap it and try it you'll know what you have. Nice hunk of rock though.

interesting . how it brakes in corners? it has been cut?

Sham it looks like hewn rather.
One side was quite flat. Already had lots of sport on it but there's still a lot to be taken off.
Thank you Jimmy!

Color wise, it certainly looks like a Thuringian. I've never seen one rough hewn like that though. That seems to be more the style of the Japanese hones. I suppose you could paint some kanji on it to add to the character!

Hope it works well, as it's a beauty to look at! I dread to think what shipping cost!

Ooops, there is still this embarrassing typo in the headline.
Thought I've edited it.

Now I know more.
The rubble hopped in front of his feet in a quarry 40 kilometers south east from old thuringian quarries.
He was probably hunting something else.
Its a very dense sand stone with a high percentage of clay he says and he doesn't know whether its too dense to use it as a hone.
When I move a finger over an old Escher, the Escher makes more noise.
This one is smoother. Lapped it with 180 grit paper. Not even finer.
There is more of this rock occasionally. The problem is only the format. (LOL I can imagine)
They should be cut with a diamond saw, which I don't have.

Well, its almost flat now (apart from two very flat dishes at the size of a dime). So Im going to give it a try the next days. If its something, we can try to look for someone who finishes some.

If it turns out well of course you will have to come up with a name for this hone.

"the Olivia Hone"

Olivia, I only have a 30x stereoscope and a few eye loupes. Even with the 30x I can look at an Escher or Thuringan and compare the appearance of each. If you have access to some kind of microscope you may be able to tell if it is the same type of stone as an Escher/Thuringan.

LOL thanks, Pyment
The surface has something of an Olive, in deed
but I guess there are better marketing strategies than naming it after a woman.

Jimmy that is an excellent idea, thanks!
I'm going to do that later tonight. (Got an old Intel Play with 10, 60 and 200x)

Last nite I could not resist and gave the little blade on the picture a couple of strokes.
It really does not seem to do much. No slurry, no metal grey on the tissue,
BUT that little blade has such a shiny bevel now and it shaves like a devil.
HHT was negative before.

I'm just about to sport the last dishes out and use it on a couple of blades,
then it goes out to somebody experienced to test.
