Watch those glass stove tops.
Was out on the lake fishing when wife called from campsite, she was in a panic. The fold back glass top shattered sounding like a gun firing, her words, while she was cooking. I removed top of...

I'm certain this directed a lot of heat towards glass top.....big pots up front.

Thermal shock (extreme fast high temperature changes).
Same thing as sitting a very hot Pyrex glass baking dish from the oven on a room temperature metal stove top.. You can do it, but eventually the Pyrex vessel will fail from thermal shock and when it fails it will be a spectacular event!
My Mom lost a few Pyrex baking dishes that way.
I treat ANY glassware with care concerning very quick temperature change extremes, even Corelle dishes (which are nothing more than dishes made from Pyrex and are amazingly hearty) are not exempt from Thermal shock (DW has broken a few Corelle dishes that way).
I learned that lesson well in freshman college chemistry lab. We were doing an experiment where we had to evaporate a solution into a watch glass. Trying to get every bit of precipitate onto the glass I hit the side of the beaker with the Bunson burner, flame leaped up and hit the watch glass which contained ice to help the precipitation. The watch glass shattered instantly, the ice fell, hit the boiling hot beaker, it shattered, and suddenly there's glass and boiling hot water flying everywhere at about 300mph. Definitely emphasized the point about why you ALWAYS wear your PPE in the chem lab, even when working with the most bland on materials. Thanks to gloves, apron, safety goggles nobody was hurt, but it could have been a different story if the TA wasn't very serious about enforcing safety protocols.
