Hello

I polished my cut slices personaly with my hands, I
use in first a little rounded broken diamond blade for
microbottoming drill over the all surface for
eliminated the all signs of the blades, after I use
papers with 150 - 400 - 800 grid and finaly, if
possible, I use a 1200 grid. In conclusion I put over
a varnish for restoration that uses my father in
laboratory, if possible to use it on the piece.
Regards

Matteo
