Sulfur in natural stone, does it affect performance.

My friend has a natural stone that contains a bit
of sulfur he says. I could smell it a bit. Does sulfur
affect performance?

Thanks

i have one too when you slurry the smell of sulfur is quite strong. i havent played much with it yet but did a tune up on a pulling razor and it worked just fine. i must experiment more to answer your question

I have found that the turkish oil stone gave off a sulfur smell when i was lapping does not doesnt affect honing though.

Sulfur is very very soft. If the stone has it you will know it as you hone.

I think he was referring to iron sulfide (pyrite). The worst kind of inclusion. Sulfur has a faint smell, if the stone does smell sulfur it means it has a high content of it. And, it is really soft. If I remember correctly, it dissolves in carbon disulphide. An easy to find liquid. Your friend can give it a try.

If it's pyrite it's usually relatively hard but brittle but should not give off any sulfur smell.
