Need ID info on a stone. Hard washita? hard arkansas? Paper weight?

Looks like a Ark. Give it a soak in hot water and laundry soap, or degreaser.
I have never seen one that color discolored from age or are there arks that color came in a wood box. Seller said he had it for 35 years or so and it was old when he got it.
Yes, oils and swarf can discolor them, especially things like ATF which I have heard of people using as lube. Also it could just be that color. Here is a small soft Ark I have that came this color.

Flatten and lap that bad boy and see what it'll do. That is the real test.
I is soaking right now but I washed it off and gave a pocket knife a few laps and it is close to a translucent. Should I lap I with anything finer than 320 wet dry??
I knew I had one. Almost identical to yours.
The pic is of the butterscotch Washita, and a med hard Ark.

I would try it there and see how it works, what kind of scratch pattern it leaves. It looks fairly dense. You can also sort of judge by the weight assuming it's not glued on a block. Finer stones are heavier.Quote:

It is really heavy for an 8x2" stone
An interesting test would be to take the volume by weight ratio,
How do you do that
Weigh it. Measure L X W X H to get cubic inches. Divide the weight by the size to get the weight per cubic inch.
Maybe specific gravity would have been a better term.
Yeah that would be more helpful too

What is the volume by weight ratio? Will that tell the gravity of the stone.
Watch the video. Specific Gravity and volume to weight ratio are the same thing with different terms. Sorry for the confusion.
Specific gravity is 2.47
On a funny side note the guy that founded Dan's wethstone is from the same town as me. Just thought that was neat
Would 2.47 make it a medium stone?
2.4 is pretty hard for a washita.Quote:

A fine washita would still be a medium stone in a razor progression.
