Failure Analysis: "Exploding" Coffee Pot

California failure analysis expert was presented with the claim that a coffee pot had "exploded" when replaced on the coffee warmer in a convenience store.First of all, there is no "stored" energy to cause an explosion. The coffee is not under pressure, and the pot is made from annealed borosilicate glass. In addition, the broken pot had been destroyed. To prove that the pot is annealed glass. The California glass expert broke an exemplar pot. It broke into large shards and the fracture surfaces were typical of those of annealed glass. Without available stored energy, an explosion is physically impossible; therefore, the injured party must have either dropped the pot or hit it against a hard object.
