How about if this stone has pores which is air in there when water touches to them puts out the air and makes bubbles?
This is what we thought at first.

For bubbles to form, I would think there would need to be some elastic quality to the slurry. Just air escaping from the stone wouldn't do that. Perhaps there is a natural substance embedded in the stone that has qualities similar to soap. I have no clue what that substance might be, but as you move the blade across the stone, air gets trapped within the elastic slurry resulting in bubbles.

Perhaps this also would explain why this stone produces results similar to an Escher and why some old barbers used shaving cream or soap on their coticules.

It's your stone's way of telling you it's time to wash your pants.

Or maybe it's a soapstone.

Seriously, I have no idea what would cause that... interesting indeed.

In Shams defense, the dirty work pants are mine. But this is an amazing curiousity and I am surprised I didnt overhone while being amused by the effects of the bubbles, It is a very good stone, cuts quickly, smoothly and is a nice finisher!

Could it be radon gas being released ?

We need Bart's input on this....

Maybe the stone is just Gassy.

Great Sham, thanks a lot. After the Charnley Forest and the Brown Escher, now we all have to go looking for a bubbling Coticule. How on earth are we going to tell in an antiques shop or from an eBay picture if a stone is going to produce foam?


jk - great job on finding yet another great hone!

I've had bubbling slurry before, and not just on a coticule but also on my Asagi and Escher. I've never worried about it - I just put it down to the water I was using

Oldengaerde this was bothering me some time. I got this couple weeks ago and when i start to use i just get confuse. what type edge it puts . feeling of the stroke is different then any other coticule i have . This is similar to chinese 12 feeling.does 10 x better job then chinese 12k it is just feeling to the blade and how it moves is similar to it. What happen to day Kelly dome over and i ended up bring that stone and give to him use it. i thought let him try . In case if something with me ? Stone does exactly how it has been performed darn babbles +nice edge. I mean really nice one.Kelly was using it and i made picture. I post this thread and thought so many people uses coticule someone should have similar stone.
It may be the old some barbr's hone and he has been using for a long time with some?? could be. Let's see what experts will say.
About charnley ,brown escher i am not only sicko in here hehehheheh. rest is front of me or right behind me. SEE JimmHAD'S KITCHEN hones.
No slurry stone has been used. dmt plate

Like Gary said, sometimes thined slurry can behave a bit like soap, certainly if there is a fair amount of steel particles in it (which makes it grey soap ) but nothing like what Sham shows on his picture.
I have not seen something like that.
How does the hone smell, Sham? Is it a typical Earthy smell, or something else. Long time ago, I read a thread on B&B where Joel described a Coticule with a terrible smell that yielded amazing results for him. Seeing the bubbles, I wonder if some sort of gas is being released. Could be a chemical reaction between the natural binder and water (it can't be a reaction with iron, as you say the hone does it with the rubbing stone too)
Does it form bubbles while you do nothing? Or do you need to stroke the hone n some way to get the bubbles? In the first case, it has to be gas. In the second case, some kind of natural soap being formed is more likely.

Interesting indeed.

Best regards,
Bart.

I've had issues like this one using a water stone that my grandfather gifted me with. I took a close look at it and it was due to its porous nature. Soaking it prior to use did away with it.
