Query: DANGER!! DO NOT BUY!!

I HAD TO PLACE THIS REVIEW AS A SAFETY WARNING TO OTHERS: I also had my 4.8 quart pyrex pan EXPLODE last night when making jello - yes JELLO. Pan was room temperature, jello mixture was not boiling. Poured into pan on top of stove (thankfully turned my back to place empty jello cooking pan in sink) and had loud POP as pyrex pan exploded into tiny glass shards. Have had many pyrex pans, never seen anything like it. Kitchen was covered in glass and liquid jello. Will not buy pyrex brand anymore after reading similar reviews. Only gave one star because it wouldn't allow ZERO. Pan was purchased in October 2010.
