The grinder head is 3/4" tall to allow you to lift or lower it to have
more grinding surface. Start by using one edge then at it wears down,
reposition the head to provide a fresh surface.

You didn't say if you've been etching with acid of sandblasting. I'll
assume you're either sandblasting or have some familiarity with how
sandblasting etches glass. It's a direct comparison. A grinder head
will not produce any smoother finish then sandblasting. A 100 grit
grind will leave the same frosted slightly rough finish as a 100 grit
sandblast. A 600 grit grind will leave the same surface as 600 grit
sandblast. If you want a perfectly smooth finish, you won't get it
with a grinder any more then with sandblasting.
