Stone #2 from the Box-O-Stuff.
It measures 2"X8"x 5/8 what do you think this one is?

Here it is lapped and a shot of the slurry it produces.

Any Ideas???
I don't think I am amy help because I only recognize the stones i have.
Sometimes the camera doesn't show the true colour of the stones, what colour is it in reality because it seems to be 3 different colours in the photos and is it a natural?
The first photos are the true color completely dry before lapping.
The 2nd picture of the 2nd post was the true color dry after lapping and it is still that color now the edges and the side I didn't lap look like the photos in the first post.
the other is wet.
Yes it is a natural stone.
It could be a thuri. A light green if the color i see is right.
It does look like a Thurigan. Lt green or blue, perhaps, but I'm not seeing the typical saw marks, seen on Thurigan, and Escher's. Still some kind of slate. Put a razor to it, see what its capable of. May make a great mid range hone, in a natural progression, or a possible finisher.
At worst, it sits on a kitchen window sill, keeping maintenance on your kitchen knives.
I will take a photo tomorrow in the sunlight (Natural Light) Should show the true color much better.
I know as much about old fancy stones as I know about nuclear physics it may be something exotic, but that one looks like natural Arkansas stones I have seen over the years, having been raised on the MO AR border. White gray, black, marbled, tan, hard soft in-between.
That stone was used so much, not sure where any saw marks would be found. From my reading on stones, the old timers used what ever was local. Cabinet maker, furniture, or maybe stock makers likely looked for specialty stones, but the average worker likely used the closest source.
In my stock work, I am always looking for a magic stone, but have yet to find one. An inletting chisel is like a razor, its impossible to be too sharp, for cutting cross grain, hard rock maple and other dense grain stock wood.
Thats neat you flattened that one, should be good for a couple more generations, if razors are its main tool being sharpened.
Looks like a thuri to me too. No saw marks but it has those lateral striated scatches and almost chalky looking slurry.
It definitely looks more green in the sunlight.

I didn't see that seam before. Is that a natural seam or is it like the coticule in your other thread where it is a stone on a backer or a 2.sided stone?
It looks like a natural seam.
I did put some steel to it that was already honed and finished in a Shapton 12000k. I will use it on my next shave and see what happens. I don't know if that is the correct way to test it but it should tell me something.
One thing I can say is I had to hole the stone in my hand to get any feedback from it.
Is that a seem or a scratch gouge?
You need a loupe. To test you get a good look at a nice shaving bevel. Then do 6 or 10 laps on the new stone and compare the scratch marks. Are they deeper, thinner, more polished and no scratches...
The shave test is the ultimate test but if you trying to find where the stone will fit in a progression...
To me it looks like a seam. scratch that I just looked through my loupe and it is not a seam it is just a mark.Quote:

I just have to decide witch razor edge I want to sacrifice to this stone. The one razor I did put to this stone was with my own edge so I did not harm any of my rotation which were not honed by me.
If it's a natural seam that's potentially a good thing. If 2 layers of stone meet naturally that are of different honable grit ranges you can have 2 stones in one.
No Thuringian for sure. But can't really help what it definately could be....
Regards Peter
Thuringians typically have saw marks along the side. It is always possible that they were lapped away but more the exception than the rule.Quote:

Yeah I didn't notice that before you mentioned it Randy. It actually looks a little like a hard Ark except for the slurry. At least I have never seen an ark make slurry like that.
Well it is not a slate. Looks more like a sandstone type of stone.
Such as for example the Gosauer we have in Germany:

How hard and fine is the stone really?
Regards Peter
It took a 300grit diamond plate quite a bit of time to to flatten it. As for how fine I can only compare it to what I have at my disposal.Quote:

But much finer than my Norton 8k but if feels a bit more gritty than my Shapton 12k.
If you can tell me a way to test how hard it really is I would be glad to try it.
Like these for example.Quote:

I never saw any saw marks on this one but that that line on yours that runs the length of the stone is also present on mine.Quote:
