Thread: Another odd sized stone

Heres yet another odd sized stone that I believe is Thuringian. The measurments are 5 13/16" L X 3 3/8" W X 7/16" thick. I have put it next to my "Celebrated Thuringian" hone. This stone is a little bit harder to slurry and is dark blue color, it slurries the same color as the celebrated hone in color but is a slightly harder stone( very good finisher). I suppose Thuringian hones or stones were cut in different sizes is my point, what is your opinion?

looks like a piece of slate ,but more pic's are needed to have positive I.D

I believe Thuringians can come in many different sizes and they are more likely to be found that way than esher co thuringians. Interesting stone if it cuts as fine as you say.

Just wanted to point out that a thuringian stone should look like slate...Cause that's what it is. :P Correct me if I'm wrong ofc. But I am pretty sure Escher thuringians are slate stones.

It's in your hands man. I know you've had hold of a least one or two Escher thuringians. Make the call I guess.

lol thuringian arent slate. Slate is metamorphosed shale and is composed of micaceous minerals, and could contain quartz, calcite, dolomite, feldspar, pyrite, rutile, graphite, chlorite, and other minerals. thuringians are much softer and are made of powder quartz embedded in chalk.

I believe that thurries fit in the categorie of an oil shale?

So thuries are made of chalk? Ok. lol. Consider me schooled. It must be very dense chalk I guess? I'm gonna go play tic tac toe with one. I'll report back. lol. Time to do some more research on this I suppose. I could have sworn I've read the words "thuringian slate" right here in the hallowed pages of SRP. But my dear friend, I must say, I don't believe you can judge the softness of the stone from a picture. Or the composition of it's mineral content :P

I will say that the dimensions of this stone do lend itself to tile setting. Now that I've thought on it a minute. lol. But I think it's a bit thick for that.

Ah I found it. Neil Miller says thuringian is a type of slate hone stone. So stifle that laugh! lol. I got the idea on good provenance.

I really think I'm right about this...lol.

i'm not saying it's a piece of slate it was just my first impression of the stone . now your link to the Thuringian Slate Mountains doesnt tell me anything about thuringian stone's just that they have a slate mountain in thuringian germany. i just dont see how thuringian could mainly be composed of slate its a harder material imo. i get my info from the internet . i can hold in my hands four different pieces of slate and one escher and none of the slate looks or feel like my escher .

you know what kingfish you mite be on to something i cant find much info on the internet about thuringians but shale is a fossilized clay and slate is the metamorphosis of clay,shale. so if the two are the same hey regularjoe i have some slate i would love to sell to you at escher prices! the two mite derive from the same stuff but arent the same stone in the end imo. so what i have learned is shale and slate have clay in them but so does coticules they are fossilized clay too.

Yeah I know that link doesn't really mean anything. lol.

But the real question is: If I had your four stones, one being Escher, and I took a poor picture in fading light, would you be able to discern the difference from the one photo definitively? If you care to send the stones, I'd be more than happy to help you find the answer.

Oh I did read that they sell Thuringian slate for both roofing tiles, and pencil leads. So there can be a big difference in hardness I guess.
