One post in. Welcome to SRP. Please introduce yourself further. Density is not the same thing as specific gravity, no? In any case, I'll take the hard Arkansas stone as shown.

Reread post #5, sentences 2 & 3.

Thanks for all the replies, guys!

Is there a specific place to do that? I've got a little problem using the forum, i keep getting "Bad Request Your browser sent a request that this server could not understand."

I would like to hear what method was used to arrive at the figures given for the OP's stones. Measuring with a ruler and cheap postal scale will not give accurate numbers.

Measured using a digital caliper, nine measurments taken on the large flat sides, six along the edges and two over the ends. Measurments averaged out to a tenth of a millimeter.
Used a relatively cheap digital scale. It has always been within 1% of the scale in my local post office, those have to be calibrated regularly so it should be pretty accurate.
2,80 can absolutely be a little off, there's always SOME error when measuring, but it should be quite close to accurate.

Did calculate a Purple La Lune, to prove what unaccury does i took the Values and changed them with reducing around 2mm on one side measurement.....

Normal Calculation
10.1 x 5.1 x 2.1 / 311 gramm = 2.87gr/cm2

Changing values
10.1 x 5.1 x 1.9 / 311 gramm = 3.17 gr/cm2
10.1 x 5.1 x 1.7 / 311 gramm = 3.55 gr/cm2

So the purple Lune fex shows a very high density. Somebody can make a counter measurement on a purple lune?

So, if the numbers ARE accurate, the stone in question could very well be of the Special Stone variety. I have never had an Ark stone above 2.67

The density of slate is between 2.5 to 3.3+, so, is the stone hard like a translucent Arkansas or the purpose of the thread is to compare densities?

[Gsssson]

The stone is hard, can't say if it's exactly like the translucent arkansas but much more like that than the escher for example.

Escher/Thuringian stones have a wide range of hardness with really soft ones as well as hard stones. Translucent Arkansas is on a different level of hardness. Being in Europe, I would not bet that this stone is an Arkansas, we have so many types of stones here. And the famous ones are a fraction of what is around. It could very well be some slate from UK, then again, that's not a bad thing, plenty of them were high quality razor stones.

Please add some daylight shots, some slurry shots and try to add a torch on the sides of the stone and check if any light shines thru....


This should be an easier way to get any process on IDing this one

How would I go about making a slurry on it? It behaves like the translucent, the oil gets some black swarf as you hone, obviously not visible on the black stone so it just shows up on the white paper towel when I wipe it off.
I'll try to do the rest tomorrow!

Do you own a Diamond Plate ? That would be th easiest way...
