Thread: Very soft coticule ?

Hi Lads.
I was thinking that this stone is a old natural combo coticule but i am bit confused. It is extremely soft and i can make a slurry very easily even with my fingers .When i was lapping it with DMT it surface become very uneven and rough ( see pics). Is it a coticule or some fake coticule-style hone.
Any thoughts about it very appreciated.

It's not a Coticule. The Belgian style has been copied for coarser synthetic hones. I assume in an attempt to benefit from their popularity.

I've never seen or heard of stone that is so soft that you can generate slurry with the fingers. No idea what it is.

Hi
.Thanks for replies Lads. What about darker side , is it look like BBW ?

From the pics it looks good to me, I see a natural blue/yellow combo. Are you raising a slurry with your fingertips or just stirring the dirt on it into mud? From the pics it does not appear clean or lapped on the yellow side.

I've noticed that this stone does not like too much water.
I lapped this stone under running water and it become even softer.
I can raise slurry (not very thick) by rubbing it with my fingers and easily scratch the surface with my finger nail. When i use a DMT for creating slurry it is thick and creamy.

Some coticles are softer than others, you may have one of them, the softer ones are usually the creamy colored ones with little visible grain on the surface or the appearance of garnet. They are natural stones given to us by the earth and therefore not subject to our ideas on quality control.

Well said. I will try to learn how to use that stone.
Thank you .

The yellow side will make a fine finisher/polisher for a well established edge.

it is not a coticule. synthetic too old and binding gone that is why you can make slurry with your finger.
