Micah,
there is a black slate from vermont thats flat as glass and responds very well to diamonds.
It is somewhat soft but responds good to diamonds-like fred said-what is its condition-if it is the one that I workrd on it scratches easily but they are easy to remove from what I remember. Use 220,400 diamonds and finish with a twister pad or something like that. Of course test for yourself to make sure you are on the right track. why grind?
Amondor-never trust info from clients-consider it corrupted. ID your stone and jobs before you write the proposal.
Control your clients in a professional manner.
Base all your decisions on process and procedures on test results and facts.
And dont be afraid to tell a client No.

Hi
This is my first go at the discussion link so hope that it works.
I've had great interest in what gets posted so better participate too.

I had a horror story happen. This past spring working on what my client identified to me as black honed granite. A person could also have confused it with some honed slate if he was not careful. This stuff turned out to be "basalt" . Beware. And run the othwer way if the client insists that you apply any sealers or enhancers to basalt.

Clearly identify for yourself all black honed stone products. Don't take someones word on it.

depends on how damaged it is. Some slate can be diamond honed. I would suggest you clean it and than test the honing powder to see kind of results you get.

Have a client looking to restore black slate, it's flat on the surface could it be diamond ground or could one just clean and then hit with a honing powder?
