Thread: Flee market stones

You got to lap the thing. I don't see how a flattening will kill the stone.as was said, get it flat with your atoma, then smooth it out with the slurry stone. And then see what you get. For coticules I usually test them with slurry and without. To see what it's made of water only after a synthetic finisher will give you an idea if it's a gem.

Since I know absolutely nothing about the thing I find it safer to ask. I do not have a slurry stone.(Yet) I have just begun this journey and have only used synthetic's so far. But I am looking forward to trying it out.

Then you can buy fine wet dry sandpaper. I don't think that you need to smooth it more than 600. Get a piece of glass or a natural tile like marble or.granite. wet the sandpaper and the base which will make them stick together. And have at it. Use plenty of water. Continue until the scratches from the 400 are gone. And then try it.

Please correct me if I am wrong. Could I use a 1000 DMT after the 400? Since I do have one of those.

Dmt makes a 1200. But it isn't made for lapping. You can try it but it may ruin your plate. A piece of wet dry sandpaper is cheap enough and expendable.

I lapped mine with a 400 plate then smoothed with slurry stone

Nice find. If you got that along with other stuff for $6 then you basically stole that stone. It's always nice to get deals like that.

Sandpaper on a kitchen worktop work very well.
Looks like it is a slate backing, not a Belgian blue: those are darker gray blue.

It's a coticule (glued to BBW base) ... I have plenty and I always flattened by using a diamond plate.

Just out of interest, how can you tell it's a BBW base?

I was told when I bought mine that it was backed with slate, is there any chance it's not slate but actually BBW.
