You really shouldn't be slamming anything into anything. You don't have to be that careful with tempered or borosilicate-style glass.

  Dave Arnold seems to think they shatter regularly.

      Not at all surprised if we're both right.

    Tempered glass is something I've dealt with extensively. Harsh temperature changes can break it, but slamming cookware against it won't break tempered glass. All the edges and corners should be hidden, so it's not like you're going to be able to whack the corner where it's weak. A tempered piece of glass is under stress, which concentrates along the edges and at the corners. That makes them into weak points. The flat side? You can hit that all day with a shovel. That said, things like scratches can weaken it. So I wouldn't be surprised if some combination of scuffing up the surface & big temperature changes were enough to blow one up. And yes, tempered glass blows up, it doesn't just crumble. Like I said, it's under stress, so it goes flying, just like the pieces of a balloon do when it's popped.
