I"ve never heard about visions corning exploding, would like to know the circumstances. My guess is that it was people who had the pot/pan in the refrigerator then stuck it in a pre-heated oven, microwave or hot stovetop. The dramatic change in temperature could cause problems.

I can't seeing something like that exploding, tho. Explosions are usually when you have air trapped inside of something like a bottle. Open-ended items don't explode. They may crack or fissure but an explosion is virtually impossible.

But actually, I've never heard of even cracks or fissure. Friend has had a set for years with no problems.
