Thread: Stone ID assistance

Just picked this up from a bin in which my father had several Arkansas stones (mostly smaller stones and sharpening kits). I'm visiting family and don't have time for proper research, but interested if anyone might recognize the stone or the stencil type labeling. It is about 6" x 2 " x 3/4", has inclusions and saw marks. Looks to have some sparkle in the sun and feels fairly fine to the touch.

Does it slurry easily, if so what color?

With family a day, will follow up this evening w more info

Was able to sneak away for a few minutes to take pics, could this be a synthetic Stone? Not much of s muddy smell, and very green fine slurry after some hard rubbing.

Now that’s weird. The only stone I have that makes a slurry like that is a light green slate, but it is soft and slurries easily. Slurry is dark pea green. It is a nice finisher, similar to a Thüringen. It is stamped on the side Seneca Stone.

The chips on the edge will be hard to lap out. The chips look flaky like a hard novaculite, but a black ark will slurry white, and is hard to slurry.

I thought the “C12 15” might indicate Chinese Guangix stone, they were originally marketed as 12k’s and called C12k’s, but were also marketed as 12-15k, though they are not. They also slurry white.

It may be there is something on your stone, oil or old slurry a good soaking in Simple Green or Awesome and scrubbing with a scotch brite may clean it up. It may take a week or so to clean up. I have soaked hard stones for months to remove oil.

What does the bottom side look like, lapping that side may be easier?

Thanks for adding more thoughts on this stone. It smells of oil, but not thick at all. Both sides are pictured above, there are some differences noticeable in the inclusions, but the light ridges look very similar, but hard to feel. There are some sparkles that show up in sunlight, could this be something from the UK? My dad had probably had it for many years. I'll put a razor on it after I get home on Thursday.
