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 […]
Tempered Glass Expert Describes Two Tempered Glass Fracture Surfaces
Glass failure analysis expert witness compares two typical tempered glass fractures. The lower photomicrograph shows a typical thermally tempered glass fracture surface . This piece is from a fully tempered glass sheet. That is; this glass has a surface compression stress of 10,000 psi or more. In addition, the compressive layer on each face is […]
Failure Analysis of Reed Switch Glass Failure
Glass expert performed a root cause failure analysis on failed reed switches. The upper left photograph shows the type of reed switch that was failing. This switch consists of two ferromagnetic “blades” that are enclosed in glass. At either end are leads that pass through glass-to-metal seals. The sealed tube is filled with inert gas […]
