Naniwa/Ebi Kagaku "Chemical" stones...any thoughts?
In the Naniwa stone lineup, there's a category of finishing stones that includes the Junpaku 純白 or "pure white" (generally mistranslated as "snow white") 8000, which has generally been well-received in its range, and the Kagaku 化学 or "Chemical" (or perhaps "Chemistry") 4000, which nobody seems to discuss.

The English site mentions the model numbers but doesn't give anything else. Too bad the Japanese site also provides no real information about them, but at least there are pictures.
I have one on the way but have not found any opinions really regarding it, and was wondering if anyone out there has stumbled upon it and given it a try. It looks like more of a soaker than the Junpaku, but that's probably no big deal.
I'm currently planning to shift from micropolishing film (which I still like) progression to mostly stones (Matsukusuyama 1k, Kagaku 4k, Junpaku 8k) before my Jnat setup.
