I have not seen something like that.
How does the hone smell, Sham? Is it a typical Earthy smell,

exactly earth 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?

NO

Or do you need to stroke the hone n some way to get the bubbles?

yes strokes as soon as starts to make slurry bubbles comes up

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.

in deed you know how i am critical about final edges. This stone does amazing Job. and i mean it. if person doesn't have a lot experience will have hardest time to find out edge comes out an Escher or this coticlule.
if you do just use blade without any slurry , blade does forms slurry after couple stroke and bubbles starts.
This excludes any slurry stone or dmt theory.
I am really surprised with this stone.

I think it came from a lessor known vein of coticule - "Les Petite Flatulences".

very rare....

The only thing I can think of is it wouldn't be from a previous user putting lather on it--these stones are completely nonporous. Anyway, I always finish w/ lather on mine & never get bubbles w/ slurry. I have no idea, but I'm glad it leaves a fine edge.

My best guess is that a previous owner used it a lot with lather or soap and that it permeated the surface of the hone- so that a regular lapping didn't remove all of it. After all, isn't most rock porous at some level?

I wonder if something in the water reacts with the stone and releases gas.

Chlorine? fluoride? how does it smell?

If it were any of the halogens (flourine, chlorine, bromine, iodine etc) They would be highly toxic, would be slightly coloured, and smell strongly...

I would guess if it is a reaction it is most probable that the reaction is something like a carbonate-acid reaction which releases CO2 and H2O. Either that or a trace metal is causing metal-replacement and giving of H2 gas.

Imo...very expert, btw...the explanation is simple.

The coti is just very fond of Sham and showing her pleasure by cooing and bubbling with unsupressed delight.

Sham, you are the man. I always contiue to enjoy your threads.

Thanks,

Mac

Sham - I am interested in this neat bubbling problem you have.....

Could you try soaking the stone for an hour?

I think that would rule out the idea of the stone's porosity being the culprit if it still bubbles...


How about stopping by the grocery store and getting some distilled water?

This would rule out the idea of chemical reaction between something in the water and the stone.....


If both tests still bubble equally, then I would say that your stone must have air pockets in the matrix of the binder and it is simply being released as you hone...

My 25c worth.....just by looking at the photos.

I’ve noticed in the photos, the most bubbles are about 1” from the heel of razor.

If they develop around that point, maybe there is a micro chip on the edge ??

Do the bubbles develop when you use other razors on this stone?

Otherwise I go with soap on the stone.

Interesting.

I have gotten bubbles on my Nakayama when using slurry, but very very tiny ones. Nothing big like yours, Sham...

I wonder if the very fine particles add a level of surface tension to the water that lets air get trapped from the honing process.
