Repairing scratches on Sandblasted glass

I have polished out scratches using cerium oxide on a leather disk mounted in an electric drill. Use the rough side of the leather and don't breathe in the cerium oxide as it's not good for you. Don't keep the disk on the same small area too long or the glass will overheat.

Wouldn't that "Polish" the sandblasted side?

If it was mine I would take the pane to a local sandblaster and have them re blast it gently.

No, that's likely to make a grit-blasted are look _less_ obscured - like putting water onto it.

What may work is careful application of a matt-finish etching frosting compound, which uses hydrofluoric acid. It's horribly toxic stuff, so somewhat hard to find, but it is available through the "craft" industries. Try to keep the application area small, as it's also likely to change the appearance of the blasted area a little. Test a small spot first. Read the safety warnings too, this stuff is dead nippy.

If you try to match blasted glass by blasting it again, it also helps to use the same media as previously (assuming it was grit-blasted not chemically etched) as this can also give a variation in appearance. Transmission isn't too different, but the reflectivity of the blasted side varies a lot depending on how it was done.

You are correct, I didn't read it properly. Since I'm such a s cheapskate I would try using some fine emery paper in a vibrating sander. And if that doesn't work take it to a sandblaster.
