That sure looks like a Turkey Oilstone with slurry stone ;)

Agreed - it is a little lighter than my turkey stone but the lines in the stone are similar.

It certainly looks like one of mine Turkeys. My one just has more fissures.

Thanks guys i was nearly positive it was a turkey its a very hard stone took over an hour to lap looks great when its wet and its got some weight to it ,it is 165mm long by 45mm wide it was 200mm long it looks brittle and if you dropped it that would be the end of it just like glass.It does get a little slurry up with some work its a milky colour havent had a chance to use it yet but will be giving it a go very soon.

Yes, it is a turkey oilstone. Don't bother try it with water as lubricant, you'll waste your time. With oil it works perfectly. And the piece you have is big enough for honing, they are generally extremely fast, so there is no need for big sized pieces. It's the first time I find the words slurry and Turkish oilstone in the same sentence. They don't work as the classic water stones, and they are already fast enough without slurry. No one I know has ever tried it, nor do they know that it can be used this way, including the owner of the mine, and until a few moments ago, me. It breaks easier than a piece of glass, very hard but it needs often flattening, that's why most of the stones that are sold, not as vintage collectibles but as hones, are at least 4cm thick.

It's like a glass can be half empty or half full, this stone is either broken or comes with a slurry stone ;)

You could probably also use water mixed with a tiny bit of liquid soap as lubricant.

Bart wrote a 6 page review on the Turkish Oilstones / Cretan hones at coticule.be and also tested the stones with slurry. I've never tried it. Because of their fragile nature they may not be the ideal stone to raise slurry on but you might like it.
