I would NEVER had believed a plate could exploded totally on its own had I not just experienced it. I have a 30 year Corelle set that I usually regularly. One plate was used as a 'catch plate' for my pet's water bowl (also Corelle). I washed both pieces, placed in the dish drainer, nothing was close to it in the drainer, then the plate exploded in multiple pieces. The water was not hot or cold, the air was not hot or cold - it was like someone had shot a bullet directly through the center of it. I was amazed and very concerned. I was thinking of replacing with a new set of Corelle but not so sure. I love Corelle because it stands up to everything, I know everything has a life span, but will the new ones do this, too???? This plate sat in the floor for 6 years until the water bowl - was out of the way - so it was definitely NOT abused. I shudder to think what would have happened if the cat was drinking from it. I have since replaced his bowls, and being VERY careful with mine until I can decide what to do.
