I do this and love it. Cleanest, fastest, easiest chamfer I've ever done.
I should write TV commercials! Just my opinion, of course !! <g>

Pick a bowl big enough to let the mirror sit about half way down
(horizontally) inside it. Begin with glass already in the bowl. Spray a bit
of water on the back of the glass, it runs around the edge of the mirror as
you work. Sprinkle your charge of abrasive around the mirror edge where it
contacts the bowls' inner surface. Place hand on mirror back and slide glass
against steel in a round motion - up and down and all around !! <vbg>

Or back and forth depending how you want to look at it. The more you rotate
the disk as you work the more evenly you bevel.

Abrasive and water creeps past the disk (sitting in bowl bottom).

If you don't keep light pressure on the glass as you work, or allow the
glass to leave the bowls inner surface,  grit will fall through and be
wasted.

The only time I tip the bowl is when I'm done and want to admire the nifty
scratches I've left in the steel !
