Special resin bond B1-13,  does not require cooling, but you may use water (or water based cooling liquids) as lubricant.
 

Grain size: Please select from the list or read Technical information.  
The finest grain size is 0.25/0 micron (fine polishing) , the coarsest - 200/160 micron (rough grinding). 
In grain selection window you see grain sizes according to standards:
MICRON=MESH(GRIT)=FEPA

Grain concentration: 100%
Do not waste your money on cheaper stones with lower/unknown concentration.
Concentration 200%- on order, 50% more expensive. 

Flat solid block on aluminum blank, abrasive grains are distributed evenly across the stone.

Available on stock 

Application
For knife sharpening  using such sharpeners as Hapstone or Edge Pro.
 
Preparation of sharpening stones
Stones with grits finer 3 microns either require preparation (dressing), or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well.
This is common issue for all manufacturers: abrasive grains are covered with bond, so you need to "release" them. 
"Stone preparation" is not available because of war.

Use and cleaning of diamond sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.

Maintenance (in 1-2 years), flattening/revitalization:
- resin bond stones - with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl. FeCl, on glass plate is the cheapest and simplest.

You may buy 100 gr. of FeCl in grain selection window. I sell it if you buy a stone.
