Manmade record coticule

In a recent post the question was asked about a manmade coticle.

Here are a couple of manmade Record Coticules with photos to show the telltale signs.

They are poured with the white, coticule layer first, usually the corners are not even with the middle of the stone where the two stones meet, some like the smaller are similar to Frictionite and have clear, uneven line where they come together.

The last photo is the inside of the box perhaps there is more information for someone that can translate.

They are Whiter and a brown second stone, not the same size of common Coticules.

I have another that I could not locate, buy have used with less than impressive results. The other stone I have also has the rust marks in the corners, from the staples in the box.

These look to be sized as barber hones. I wonder if man made coticules made in larger sizes as well.

Strikes me to be a good way to utilize the scrap left over from lapping and shaping regular coticule hones.

Yes, years ago I have seen photos of larger bench stones in the 7-8 X 2-2.5 inch range.

They had the same white and brown layers.

What are they made of?
Have they pressed somehow the dust of natural coties together like it was done for thuringian JGERAS hones?

About a year ago, I saw a photo form the Coticule mine in Belgium where they had a huge pile of Coticule debris where they had dug/blasted through rock looking for good veins. When I saw it, I wondered if anyone had ever ground it up and pressed it into man-made hones. I guess they have.

Dick out of Germany sells or sold a reformed coticule. It is a woodworking site IIRC.
