This is a bummer as I had been thinking about grinding my own for some time now. I'd like to know more about it and how I can protect myself.

The only part of the wikipedia for Silicosis that mentions glass is about manufacturing it and, even if it includes the grinding part, the reference it links to doesn't mention glass or grinding at all.

If you have more pointers or keywords about this subject, please let me know!

You're supposed to only grind wet, since the glass dust is a hazard. Grinding wet keeps it from being airborne.

Everywhere that I've read about grinding mirrors (and I've done a lot of reading) always says to grind wet. Any YouTube video you watch on the subject will also show them grinding wet.

When grinding a mirror you put water and grit on, grind until the grit is used up, wipe it off, and repeat. This is called a "wet".

The process uses wet sand. It's not hazardous.
