In the days before I bought a wort chiller, I used to pour the hot wort into a glass carboy that sat in a tub of ice water. I had done it a few times before without any problems, but on my third batch I went to lift the carboy out of the tub and the bottom literally fell out! There was no sign that there was any problem when it was cooling as the glass sheared off exactly where the bottom was fused to the sides.
Not only did I get pissed since it was a major mess, waste of 5 gallons of good wort, and many lost hours of work, but mainly it was a carboy that my grandfather used to make wine in. The carboy was at least 30 years old! I've since learned my lesson and use a wort chiller for cooling.
