Thread: Stone id help

Hello , I have this stone for a while, bough it on ebay from USA. It is 5 long and 1 1/4 wide. It is extremely soft, like Escher,
But leave a much sharper edge than an Escher. I use it just with water, 25-30 x strokes are enough to improve a Naniwa 12k edge. Slurry is orange color. The sharpening felling is exactly like Escher.

I have no idea what it is. But how is an escher "extremely soft"?

I consider eschers to be very soft stones, they need just couple passes on DMT plate to became flat. Comparing them with coticule I consider them soft

looks like a smooth brick :P

Lol...looks cool, have zero clue what that is though

I don't know about very soft - I have just done a couple of days of lapping, and in increasing hardness I find the following:

1. blue escher (thuringian)
2. blue grey water razor hone (thuringian)
3. grey celebrated waterstone (thuringian)
4. silkstone
5. general yellow coticule
6. 'la veinette' coticule
7. dalmore blue c/w dark greyish tam o'shanter
8. light grey tam o'shanter
9. red figured charnley forest
10. grecian oilstone (LI variant)
11. muted charnley forest
12. Llyn Idwal (featureless, quite uniform)

To be honest, nos. 1, 2, 3 and 4 are very, very close; 5, 6, 7 and 8 are very close and not that much harder than 1, 2, 3 and 4; 9, 10 and 11 are noticeably harder than the others and 12 was the hardest of all, by a significant amount.

I suppose comparing an escher thuringian with a llyn idwal (these differ - some are softer, this particular one was very hard) then you would consider the escher a lot softer and easier to lap.

These all being natural stones, it is only natural that others will put their specimens in a slightly different order. All part of the fun.

As for the OPs pictured 'unknown' it bears a passing resemblance to some of the pictures Hatzicho has posted of 'red' or 'rouge' hones (lorraine/fox/goldfisch/salmon pink coti) in some of the pics at any rate. The first three are all 'much the same' but the slamon coloured coti is quite special. I wouldn't hazard a guess though - Hatzicho would be the man to prove/disprove this line of hones.

Could be a Lorraine Stone...definately no Rouge Du Salm or a BBW....

The Lorraine i own has a darker red going into a certain Vine Red, but that could be also because of the different light conditions...

I also have such a unknown candidate, very soft, slurrying very easy...leaves a fine and smooth edge...

@Livio: can you clear your PM...mailbox full

Thank you all for your input, for sure is not a BBW, that I know. What it make unusual is orange slurry. I have never saw something similar.
