In glass failure analysis one uses evidence such as the attached photograph to demonstrate that a nickel sulfide particle can initiate tempered glass failure. The NiS particle is at the center of expanding Wallner lines. The Wallner lines are used by the glass failure analysis expert to track the direction of the crack growth. In […]

Nickel Sulfide Particles in Tempered Glass
Glass failure analysis expert witness performs a failure analysis on a tempered glass window. The failure was initiated by a nickel sulfide, NiS particle. The glass failure analysis expert was able to retrieve both halves of the failure origin. One side of the failure origin contained the protruding NiS particle. On the other side of […]
Glass Expert Discusses Tempered Glass Fracture Surfaces
California glass expert witness discusses crack travel directions during tempered glass failure. During tempered glass failure the glass sheet “self destructs” because the internal residual stresses are tensile and drive the failure. Essentially the glass failure results in the glass breaking into tiny cubes. This means that the crack is constantly changing directions. The California […]
Glass Expert Performs a Bottle Failure Analysis
A California Glass failure analysis expert witness was asked to examine a failed wine bottle. A portion of the bottle top broke off midway down the cork as the cork was being removed. The root cause failure analysis revealed that the bottle had received a impact to the side. The distinct Wallner lines (see the […]
Glass Bottle Damage; GLass Bottle Failure Analysis
Glass expert illustrates wine bottle damage that occured during corking. This product defect occured during cork insertion. The “push rod” was off center, and it impacted the top of the bottle. As a result, there was a crush point that would have resulted in a crack during cork removal by the user. Glass failure analysis […]
