California glass failure expert discusses the safety aspects of tempered glass; Tempered glass is safer than standard (i.e. annealed) glass because “dices” into small pieces under certain failure modes. In reality, the overall glass failure is driven by residual stresses put into the glass by the tempering process. That is, tempered glass “destroys” itself. If […]
Bottle Sealing Requirements
Glass expert discusses a manufacturing defect that can prevent the sealing of a bottle. The client was using a Polyseal 01 with a cap to seal 750 ml bottles of a solvent. These bottles were packaged 4 to a case and sent to customers. During shipping a fixed percentage of the bottles would leak. A […]
Pyrex Glass Bakeware
Glass expert discusses recent changes in glass bakeware: Traditionally glass bakeware was made from Pyrex type glass (i.e. borosilicate) glass. Borosilicate glass has a lower coefficient of thermal expansion than soda lime glass, and therefore, stresses generated by thermal gradients are less. This has changed. Now glass bakeware is made from tempered soda lime glass. […]
Analysis of Failed Glass Baking Dish
Glass failure analysis expert analyzes failed glass baking dish”Pyrex”. Traditionally, glass baking dishes have been made from annealed borasilicate glass (i.e. Pyrex glass). Now baking dishes are made from tempered glass. The glass is still called pyrex but it is really tempered glass (soda lime). As a result of this change, the newer dishes are […]
Manufacturing Engineer and Product Liability
Product Liability, Design Defects and Manufacturing Defects are obvious arenas for an experienced manufacturing engineer or process engineer. He has the insight to best evaluate manufacturing defects in product liability cases. Naturally, he must first perform a complete root cause failure analysis to determine if there was product misuse, a manufacturing defect or a design […]
