We also used Pyrex and Kynex glassware in the labs when I was in college, in chemistry. Nothing ever exploded there, but then the glass was thinner than a baking dish. We used to expose that glassware to all sorts of temperature changes too. I would call the use by most of the students rather "abusive" in fact.
I guess NOTHING is safe anymore!
