Glass Coffee Pot Failure Analysis: Thermal Shock Failure Of Borosilicate Glass Coffee Carafe

By: Dr. Thomas Read

The fatigue failure initiated on the outside bottom where the carafe had been scratched with the abrasive scrub pad. As a result of cyclical thermal shock (between 195°C and 15°C), the cracks grew progressively till it reached a critical length. Glass thickness at the origins is approximately 3 mm. One failed after 12.

Glass Failure Analysis: Glass Oven Dish Failure

By: Dr. Thomas Read

The annealed borosilicate glass pie plate failed as a result of “thermal shock”. There were multiple origins for the failure, and these all initiated at damage sites on the bottom of the Pyrex baking dish. It appears that the bottom of the pie plate was convex. Thus, setting the dish down and moving it on hard (abrasive) surfaces such as tile or granite counters created bottom “rim” damage.

The Aerosol Laboratory: Safety Check - Ignition Source

By: John Chadwick

I have been wandering around the aerosol industry for the last 35+ years both as an employee of major CPG companies, and, for the past 15 years as an independent aerosol technical consultant. While the attention to safety issues has dramatically improved over time, I am still amazed how often the simplest safety precautions are sometimes overlooked when filling aerosols with flammable propellants. I'll save my horror stories for another time, except for one particularly relevant example at the end of this article.
