Glass failure analysis expert performed bottle strength tests to determine the strength of a cylindrical glass bottle. The bottle is approximately 0.85″ in diameter and 2.35″ tall. The glass thickness is approximately 0.040″ thick. It was hypothesized that a female could squeeze the bottle hard enough to crush it. Glass strength was measured by compressing […]
Glass Expert Discusses Visibility of NiS Particles
Tempered glass failure analysis is mainly difficult because the panel disintegrates into a very large number of semi identical particles; therefore, the failure origin is impossible to locate. In several cases Read Consulting has had the opportunity to examine several failed (caused by Nickel Sulfide, NiS, particles) tempered glass panels that have remained intact. In […]
Glass Expert Performs a Wine Bottle Failure Analysis
California glass expert performs a failure analysis on a wine bottle failure. In this case the root cause of the failure was due to an impact on the top of the bottle finish. it is apparent that this bottle was hit on the top. This is shown by the photomicrograph.
Glass Failure Analysis Of Bottle Defect
California Glass Expert Witness was assigned to determine the cause of failure of wine bottles at the manufacturing facility. During processing the bottles had a higher than normal failure rate. A root cause failure analysis was performed by the glass failure analysis expert witness. He inspected a large number of whole bottles and removed those […]
Manufacturing Defect on Tempered Glass Window
Glass failure analysis expert witness performed a root cause failure analysis on window defects found on a recently built custom home. The upper left photograph shows the defect from the building exterior. The window defect resembles a dust or dirt streak and was not detected until the post construction window cleaning. In all cases, the […]
