Very nice stone in a perfect size... and, a Burton. Impressive!
A very good 8"x1.5" from Burton Rox, bought in Belgium in 1990. I tried to photograph the surface as precisely as possible. These dots and scratch-like texture says nothing about the fineness of a coticule. This is a very fine one, the dots are not big garnets or the like. I think it's a La Veinette. It has some blushing at one end, it has a hybrid layer at the bottom of the yellow side, is glued with Araldite and is medium hard at the top. A great razor finisher.
A very nice stone Musicman. These dots seem to disappear a few mm below. But these are no inclusions for me. They are not harder or softer, they just have a different color. With a good lupe you can see that these are no garnets, they look like bubbles and have no effect on honing. Lets say its like "goma" on Japanese stones. Yours look like a La Dressante to me. They can be homogeneous like a piece of butter, some have those dots too. They also have layers that vary in color and hardness, usually they get darker, the closer they get to the blue stone. But they also vary in grit. Some are super fast and some are very slow and so on. I like the blue in your stone. I am just about to lap a very old one flat (~9.7" x 2,15"). It is glued with old yellow resin varnish. There is not much yellow stone left, the blue material that can be seen on the side on your stone pops through on top here. But it can not be felt, the surface is very smooth. This one seems to be a slow one, its harder than my La Veinettes.The sides of your Burton are very similar to my 8x2. Layering, vertical black splotchy lines, and small hybriding. Mine has a creamy looking top though - do the dots on yours disappear if you look deeper into the layers? Not sure if mine is Ol’ Preu or Regne.

I had a hunch mine was a La Dressante, it's got the almost icy smooth super fine feedback LD's are known for. By the blue in my stone, do you mean that 1 inch long grey blue area, or the much longer dark green stuff at the bottom of the yellow layer? That's probably hybrid material, but the grey blue I am not sure.
You might able to tell I filled in a few areas on the sides of my coticule with superglue, including the holes in the grey blue area.
Thanks, you could be right of course. I thought La Veinette because I got one from Ardennes Coticule that was very similar. It has this hybrid layer along the adhesive surface and such layers with slightly different colors. But its not that important to know I think. I like the stone because its a very good final finisher, for me, this counts more than knowing the layer.It looks like Nouvelle or possibly Dressante to me.
