I have used fine grades of wet dry paper in the past to frost glass.

I'm sure we've got enough folks is this group who have sandblasted. Need to
make some clear glass into frosted for a light fixture. Is is reasonable to
think I can sandblast the back and get a nice even effect across the glass
(round piece, like a salad bowl, 24" across, 10" deep.

Thanks.

Acid etch may be a better process than blasting, if you don't have the
right media. We used to frost and cut glass using a sandblaster, but
we only used extreme flour grades of carborundum.

You are going to have to adjust the process to match your desired
result....
