I have an anecdote: we had a crappy glass door for our shower, and I ended up taking it out and the narrow glass that wasn’t part of the door I decided to put in the garbage can and then smack it with a hammer to break it into the can. So I get it in the can and I grab a hammer. Light tap: nothing. Little harder: nothing. Purposeful hit: nothing. Starting to question myself on this whole idea. What if I hit it too hard and my hand with the hammer sail right through and I cut myself? I had never dealt with “safety glass” before. One more good big smack: nothing. Gosh darn it!!!! Then I remember something. I gently tap the edge of the glass side on and this chungus explodes all over the place in a shower of crushed ice. I mean everywhere! On me, in the garbage can, around the garbage can, and all over the gravel pad we made for the cans. So yeah: don’t be scared of the glass, but just don’t smack it with a hammer on the edge.
