Do you ever get airlock issues where the glass slides around too much? Have been considering a glass layer on a desk project for a while but I'm concerned one wrong move and it could end up on the floor!
Install corner brackets (permanent) or an edge lip on three sides with a rotating lock on the fourth (semi-permanent) or get it drilled for flat hinges (liftable).
Or use double-sided tape in a color matching the underlayer.
It's way too heavy to easily move around on its own. Of course, my desk is an old, non-smooth finished wood desk, so there's no air-gliding on it. A smoother desk would probably pose a risk of sliding, but could be solved by adding some friction areas (carpenters tape on the sides of the glass, maybe)
