Slurry without replenishment only lasts a time measured in seconds. Here's how my experiment came about.
I was interested in polishing knives, not honing a straight, and had the idea that I'd use small pieces of uchigumori or suita to create slurry that could be used on glass, felt, etc to create the kasumi finish since large pieces of pure uchigumori can literally be $6-10K, and are difficult if not impossible to even buy (not that I would!). Whhat I found, and Alex Gilmore independently when I discussed it with him, is that off the awasedo the slurry only polishes, you cannot create kasumi off the awasedo!
Alex had tried tomo slurry on glass and found the same result -without the host stone releasing its own slurry, the transferred slurry only polished and was depleted in a period probably best measured in seconds.
So I'm interested in hearing people's experiences!
BTW, I save the slurry from lapping my Jnats or spent tomo slurry on small pieces of lint-free paper and use them to clean my razors after use. I let them dry for storage the just spritz them lightly for use. Too much water leaves slurry on the blade. You can also use these slurry "wipes" to polish fountain pens and the most delicate finishes like polished gold. No kasumi.
