How do you test an unknown natural stone?
Got this stone on eBay. Would like to know how some of you go about testing an unknown stone. I think it's a Turingian. I thought of finishing a razor to an 8k, then try the stone and test to see if it improves. Just curious to see what other people do. Thanks in advanced, Double O

How do you test an unknown natural stone?
Tongue test. Best way to determine.
The other unscientific way I use it to determine how quickly it'll absorb water compared to other hones. Faster, lower grit.
