Thread: what stone to lap/make slurry for escher?

what is used for escher slurry + lapping?

thanks

Thank you.

I am wondering if another stone is good for the slurry - e.g. a Belgian or other

Maybe something really hard like a (chunk of a) barber hone?

I think the best approach is to use a stone that is softer than the honing stone. If you use the same stone they are both of equal hardness and you are going to be wearing down your good stone as well as putting scratches and possible nicks in it. With water stones you use a Nogura which is essentially chalk and very soft.

I lap my nortons with a green DMT diamond dust hone. this works well for me and also creates a fine slurry from the stone. I would try this on any stone and expect good results

I guess the base question is..what should the slurry be made from? When one uses a Nagura which is soft I would think 90% of the slurry is the Nagura which has worn away on the surface of the other stone. If that is so, does it even matter what the base stone is since it is not the one in solution, forming the slurry.

If one used a harder or same type stone the slurry would seem to now be the base stone, with either similar grit size from being released from the matrix or finer from being crushed as it was released by rubbing.

So far I have always used a similar stone, Coticule on Coticule, Escher on Escher and my Thuirningens come with another, smaller Thuringen.

Any thoughts on what is really happening when we create a slurry?

I always assumed that a slurry was made with a stone that is harder than the binding matrix of the waterstone but softer than the abrasive particles suspended in that matrix. The point would then be to scrape away some of the matrix, loosening a few abrasive granules from it and giving greater exposure to those still on the surface. This is the way I understand it to work but I cold be wrong.

Oh, I'm getting close to that one, but what you guys are talking about might as well be Greek to me.

I did actually find it a few years back but forgot to write it down <g>
