Tempered glass will explode if you chip the corner??? I'm going to need to see a video or something to believe that

Here's a video with a guy tapping the corner with a hammer: https://www.youtube.com/watch?v=hsXZVMEsGzY https://www.youtube.com/watch?v=hsXZVMEsGzY It doesn't need to be like that, just clipping the corner when racking it or having two pieces tap edges while it's on a conveyor will do it too.

Exploding glass shower screens are a thing. Usually due to damage to edge during installation (or manufacturing defect) and/or change in temperature.

  In the factory, they sometimes seem to just explode randomly when the pieces next to them are just fine. It might be some anomaly of how they got quenched and/or temperature changes, though. I remember it mostly happening in winter for whatever reason, so maybe a cold breeze got them? There's probably quite a contrast between the furnace and the cold air coming in around the loading docks.

Yes, that's why they always protect the corners with a metal frame or put them in a window, etc. Though doing edgework beforehand may help avoid that somewhat. Two pieces on the conveyor out of the quench running into each other is probably the most common way to break them in the factory other than having them explode in the quench. They also break in people's hands when you chip the corner on the racks they're loaded into, which usually makes the unloaders jump when it happens, because they may be holding a 30"x70" piece of glass that gives them a shower. Oh, and the damn stuff can just break spontaneously. It might be due to temperature changes in those cases, it's not like anyone can say, but every so often a lite sitting in a rack will just blow up even when nobody is near it, though it's quite rare. From what I recall, it most often happens in winter. Source: I worked for an cut & temper/IG operation for quite a few years and saw everything myself.

Tempered glass certainly explodes with minimal damage done to it. I've had plenty of panes blow on me at the solar panel manufacturing facility I used to work in.
