guys, that last post was from 08......lol.

but my .02 is if its tempered glass a small chip or pressure point can appear fine untill all of a sudden the pressure is released.

had this happen when i was having a dinner party, a guest dropped a cup but it didnt break, only a tiny chip off the rim, put it on the counter and got a fresh one. to our disbelief about 20mins later the cup exploded, sending glass accross the room

Safelite runs an ad on TV showing a tiny star crack in a windshield from hitting a pebble, then the car hits a big bump and the windshield shatters. They claim that if you let them fix it with their glue they inject into the crack it will prevent catastrophic damage.

Usually only cookware and measuring cups are tempered. Drinking cups are mostly just plain glass. My measuring cup has about a thousand chips in it from people whacking spoons on it. It still reaches temperatures well above 200 degrees and comes back to room temperature on a daily basis.

The windshield is glued directly to the car body. Side windows hang on a rail. Stress coming from hitting potholes or twisting the frame aren't really even comparable. Also the windshield doesn't shatter in the commercial, it goes from a small crack to a big crack.
