Hello list,

A few weeks ago I bought a NWA869 thin section from an eBay seller.

The seller is not Mirko Graul (excellent thin section seller, excellent
person, my favorite thin section provider) nor any known thin section
seller of this list, OK ?


When received it looked darker than usual and after measuring thickness it
was 100 micrometers instead of 30.
I just contacted the seller to prevent it from selling more thin sections
like this and having problems with costumers, but in a educational and
collaborative way, as I think he was new in thin sections and did not know
about the problem.
The thin section was really cheap, so I keep it, no problem.

Ok, well, my help claim is because I want to grind that thin section to 30
micrometers and I think the best way is to do it the same way as I did when
I grind my telescope mirror, using a second glass as a grinding tool.
Any suggestions?
Do I use carborundum 2000 or Aluminium Oxide?

Thank you.
