Over the winter I got hold of few stones which I am not clear about what they in fact are. Any information about them would be appreciated. Thank you.
With first one I am not sure if the box is original. The stone looks like arkie.
The second one is big question. The box looks like original writting is in Russian. When you open it the writting is probably in German.
The Browning looks like a glued Arkansas/Washita combo to me. The other a coticule combo. :thinking:
To me, the second one looks synthetic.Quote:

Isn't there a German website that sells coticules with "Brocken" as part of the name of the company ? I believe I've seen that IIRC. :confused:Quote:

In Outlines of Mineralogy vol. 1 Kidd mentions that the yellow/ blue colouring of the Coticule is often imitated in artificial stones due to the excellent reputation of the Belgian stone. I think what you have is a synthetic imitating a Coticule, however the wording reformed brocken, brocken translating as chunk, leads me to believe it may be a natural abrasive powder with a synthetic binder.

You have covered my options. I am curious if somebody has something simmilar or at least experience with it.
'Belgischer Brocken' or 'Belgian chunks' is the common German name for Coticules, originating in the irregular shape of most of them. The French 'bout' has the same meaning. 'Reform' can mean 'reform', but also has connotations of 'new', 'improved' and may not per se be taken to indicate the hone consists of reconstituted natural hone matter. The Russian 'реформенный обломок' is a transliteration of 'reform-brocken'.Quote:

The German, looks like one I bought slathered in oil and caked in black swarf. I believe now mine is a Coticule combo. I thought it was a synthetic because the seam between the blue and yellow is perfectly straight except on one edge, very much like yours.
But after cleaning and lapping it cuts just like my Coticule I bought from Ardennes. The stria is identical.
Looks like a Coticule, Cuts like a Coticlue, Smells like a … well, it still smells a little like kerosene… but I still think it’s a Coticlue and didn’t pay any where near Coticule prices.
Two good scores Lap them up and enjoy.

It's the side view of the hone that makes me think it is not a natural. The border looks like it was poured and the texture looks wrong. If you magnify the image you will get a better sense of it.
I could be wrong.:shrug:
This one isn't a Coticule, it's artificial. Quite sure of that. With what I wrote above I just tried to indicate that the name does not (as Alex suggested) imply it was made from reconstituted hone matter (he's spot on with the rest, of course).
1 of them is Russian language and it says
Red side is course and yellow side is fine.
you have to use with water. rest couldn;'t read
There certainly exist synthetics designed to look like Belgian naturals, right down to the fake wavy seam. I know because I've had a couple. The ones I've had cut totally differently (and much more coarsely) than a Belgian; the yellow is too garish, and the blue or grey looks like asphalt more than slate; and they smell different. Synthetics smell like tarmac or a gas station; Belgians smell musty and earthy, like a combination of a greenhouse and a damp basement.
At any rate it shouldn't be too hard to tell once you've experimented a bit.
I agree that that one looks synthetic, but only the guy who has it in his hands can say for sure.
In my experience, BBWs all have a characteristic stippled surface that remind me of pigskin suede. It would be impossible to capture that signature in a synthetic. A close up of the blue side would help.
