Thread: Please, help me identify stones. Part one

Bought two stones recently, can't identify them. May be somebody can recognize them. On the attached photoes two stones; dry, wet, semiwet

Is not easy, for me looks like Thuringian or Welsh slate.

Hard to say. What about size? Colour of slurry? How easy is to lap it? How is the feedback?

Size of bigger stone - 8' x 1' and 6/8 x 1', smaller one - 6' x 1' x 1/2. Both stones are very hard to lap, they have small scratches, which are very difficult to remove. Smaller stone on wooden platform which looks rather old. Color of slurry of both stones is creamish. I have not tried to hone anything on these stones yet.

Based on size and colour I would guess Welsh slate at the left and a light green Thuringian at the right. To be sure it's Welsh slate you can compare it to close-ups of Dragon's Tongues and Yellow Lakes which can be found at the forum.

Thuringians are easy to lap so it could be something else entirely. Maybe even a CF if it's really really hard. I can't tell from this angle.

I don't know what is CF, but the stone is really hard. Very difficult to lap? Especially the bigger one.

DT or YL are not that hard to lap. There is one type of Welsh slate which is hard (it sparks even with wet saw) however still soft in comparison with CF.

Hmm Welsh slate isn't that hard either, we will need better pictures Try taking pictures in the shades for a better contrast of the stone.

A CF is a Charnley Forest Hone, often olivegreen with red/purple streaks or veins but sometimes all green. The green usually has multiple shades and/or patterns. Sizewise I don't think it is a CF but who knows.

Have not seen 6x1 right angled size yet even thought the colour and slurry could be right. However it is still hard to lap harder than any welsh slate.

+1 on the above posts.
I have neither a Thuringian or Welsh slate so I am no
help in the ID process. However I would be happy to
pay postage and give them a couple years of evaluation.

For many natural hones the history and locality is
critical to making a good guess at naming many a hone.
Even modern man made hones should be marked
and kept with the original box when possible.

The scratches may be from a very coarse lap.
My DMT extra extra coarse leaves scratches
like these on my Chinese12+/-K water stone
These need to be minimized with 3M
wet dry or light touches with a finer DMT.

I guess I need to read part two now.
