Interesting looking stone, but I can't tell what it is. What grit wet sandpaper did you use? I would try a really coarse 220 grit on a flat surface, if you haven't already, until you get a DMT. The edges of your stone have been beveled. I tried to do that with one of my black Arkansas stones, but it was way too hard. Maybe yours is softer than a black Arkansas. What I hope you have is a large Thuringian. Did any slurry form when you tried lapping on sandpaper? If so, what color was it? Let's see what some of the HAD folks with lots of different stones think, when they wake up.

I went through about 2 packs of 220 sandpaper and the same with 400 when I ran out of 220, and as you can see there is still a dark spot in the center.

It did form a slurry when I lapped it which is a milky white with almost a faint cream tint to it. Dried on glass looks kinda light gray.

I just ordered a Coarse grit DMT so it should be here in a few days. Also got a Norton 4k/8k and a prep stone. Hopefully that will be enough to sharpen up the older razors I found at the antique store. Most of the edges are in pretty good shape.

My sharpening arsenal will consist of the 4k/8k, whatever this stone is, and I ordered one of those wool/cotton strops and .5 dia spray and chromium from SRD.

The coarse DMT is 325 grit. I lapped my hard (brick) with a DMT 125 and it took forever I use the 325 to dress my other hones as it leaves a nice smooth feel up to the 8k hones. After that I use the 3k shapton GS to polish the finer hones.

You have a nice looking stone there

Hopefully it won't take too long, I've gotten a lot done with sandpaper. Even if it does take a while though, at least I won't be burning thru sandpaper $5 at a time.

I had considered getting the XX coarse, but I also ordered a Norton 4k/8k and I didn't know if it would be too coarse for the 8k, and I could only afford 1 DMT right now.

I still just want to know what kind of stone this is. It's driving me nuts.

I think I'll just consider it and use it as a final polisher off the 8k until I hear otherwise.
