Thread: Are these stones coticules?

I'm afraid I'm not a strait razor user at this point. I found this site while researching hones and I'm hoping someone can confirm if these stones are coticules. What's throwing me is the naturally occuring purple colored lamination, is this consistant with blue coticule? I'd been using one of these for years with my cutlery not knowing what it was but very happy with the results. All the stones develop a nice slurry. Thanks for your observations and expertise, Jeff

That's a terrible photo! They do look like they're natural BBW/Coticule combinations. I'm fairly certain. What size are they? Very nice.

Hadn't looked at the links.
Couldn't be sure on the others. There are too many possibilities without seeing them & getting a feel for the texture & i'm no expert. They do look nice though!

There's one there that looks like it may be two slightly different layers of yellow coticule. You may have a Coticule/Coticule natural combi with each side having slightly different qualities. Now that would be cool! I don't even know if that's possible though!

1st one No. Next 2 yes.
Not sure about the linked photos..

The bottom two are natural combo coticules - the purple is blue and the yellow is, er, yellow.

From the picture that's underneath your post, I am fairly confident that n°1 and 3 are natural combination Coticules. N°2 is probably a Belgian Blue glued to a Coticule.
N°1 has a rarer red backing, which, according to my information, cuts much faster and a bit coarser than a normal Blue. This is a hone I'd like to get my hands on very much.
From the other series of pictures, I'm almost certain the right one is a natural combo Coticule/Blue, but it wouldn't surprise me that the others are Coticules as well.

That's quite a treasure you got there.

My thanks to everyone for your responces. I spent many hours cleaning, lapping and using (developing a slurry with) all the above stones and their characteristics are so similar that I've convinced myself if one is a coticule, they all are. Last week it had occured to me that I didn't need all the stones I had accumulated over the last 20 years and it was time to downsize. So I drug about 40-50 lbs of stone into the house, filled the sink with hot soapy water and started cleaning. Before last week I had never heard of a coticule and untill I visited this sight I had also never heard of a Thuringian. I thought that the black stones in my pile were all Arkansas but after further study, comparison, lapping, honing and developing slurries I believe I also have at least several or more Thuringians.
I've probably learned more about hones here in the last couple days than I'd learned in the entire lifetime so I'd also like to thank the many contributors to the knowlege base of this forum. These are a few more of my stones that I'll continue trying to ID. All produce a slurry and a fine edge. Due to their hardness, I don't believe I have any slate and they all display a reflected image when held at a low angle (7°-10°). Many but not all will be offered at auction when properly identified. Thanks again for any additional observations, Jeff

And here's another odd one, works up a slurry but slowly. The side look as if there are green inclusions but I dont see the green from the edges.
