thni chips at the edge are of no real problem other than your vanity. I
will note that if you don't have any bevel on the edge of the mirror, those
chips do happen.  The bevel should be at 45 degrees also as anything much
steeper will just spall off larger chips. Do try to keep the tool from
rocking on the edge of the glass so the superhigh pressures that make that
spalling of the glass doesn't happen. Bob May
