Sorry, my photos aren't turning out very good.

I will try to asnwer your original question, which as a learning experience I thought I'd try.

At first i should mention coticules are natural stones.
Their grit will differ from 4k-8k level sometimes 10k.
I have seen always People advice to use Coticules by making slurry ,then diluting etc.
i Think this is misguiding.
I understand more people will be against me then agree with me .
In fact if anyone could answer this question or show me what i am looking for then i would be gladly change my mind.
Now has anyone ever seen boxed coticule with slurry stone?(old ones)

No, i personaly have not read of it in historical context. Isn't that trying to prove a negative though? I believe that the use of slurries isn'yt unheard of nor do I find it unlikely that it could have been used. I'll galdy concede the point though.

Coticule always been used with water, lather, or Oil.
the finest edge you can get using it with oil.
fastest cutting action you will rich by using lather.
Question is can you use it with slurry and sharpen razor faster?

Yes, at least that has been my experience. Both in the past, and tonight with my honest effort to give your suggestion a shot.

? typo?

It's a tool. I use 'em all the time. They all wear out. In spite of the the coming price hikes, I'm fully prepared to buy another stone. If it was a $500.00 escher, I'd still use the bloody thing.

you will get maximum out of the coticule spending less time just by using water then using it with slurry then diluting and getting the final edge from the stone.
Let me explain this a little more.
if you take the coticule
then make slurry and hone the blade.
then diluting slurry slowly until you will end up with water and make strokes curtain amount to get final edge from the stone.(takes 300-500 strokes total .sometimes more)
This process will take more time then just using your coticule with water without making slurry etc.

This is exactly the opposite of what i found.

You will spend less time .
hope this helps.

I tried quick again to get a slurry build-up on the stone, it took well over 5 sets of 20 half strokes, (100) to build up enough to be plainly visible. Under the lighting conditons i have and my poor photographic skills, my photo look like nothing. And yet another hundred as i type this still hasn't brought the edge back to SAH though there is some grey showing now.

The thought occurs to me that I may not be using the term slurry apropriatley. i make a distinction between swarf and slurry. Swarf is what I consider waste steel in the water, which is what I would call the result after 200 strokes on my stone with water.
I think of slurry as a mixture of water and an abrasive medium. I wasn't getting any abrasive material with water alone, so i'd be more correct to say that I see a build up of swarf.
