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

[Gsssson]

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...

Give it a nice lap with sandpaper, it might clean the stone from excess oil on it, especially if it isn't porous. Rubbing the stone with some sandpaper will show us the color of the slurry as well, preferably on the stone and, if it does, it kind of proves that it's not an Arkansas stone as that kind of stone is too hard even for sandpaper.

No sandpaper available at the moment, so slurry shots has to wait.
This is as much daylight as I've got on a cloudy day late november, the camera still used the flash when set on auto so I had to turn that off. :P There's no light at all coming through the stone (tested with much stronger lamp too, but no photo of that).
