It looks like some kind of slate, maybe a welsh one? I don't know a lot of them but it looks like a grey version of my purple slate.When i have seen pictures of this stone my first thought was it's a thuri
When finely got the stone in my hands was a little surprised
26cm x5cmx2cm
With a 4cm slurry stone
Looks like Thuri but I think it's not
It takes minutes to raise slurry
Thin misty hardly visible slurry
All most nothing at all
It is a hard stone
Tried to finish a razor on it and it looks like a good finisher
Totally different finishing properties than the thuris that a have
Could you please share your thoughts about this stoneView attachment 1306635View attachment 1306635View attachment 1306637
