Query: Beware - explodes! Google "pyrex complaints" and research before buying.

My wife bought a 9 X 13 Pyrex glass pan several weeks ago to cook lasagna for our dinner party. Took it out of the oven and it exploded like a grenade! Glass shards flew across the kitchen into the dining room. Could easily have blinded her! Google "pyrex complaints" and you'll see there are hundreds of similar instances. We contacted the manufacturer and got offered a new free pan. Thanks anyway, we don't want to dodge glass shrapnel bombs.....
