Glass in Chocolate Bar


A law firm representing a world-renowned candy maker faced litigation involving a consumer complaint. The complaint was about glass fragments that were allegedly found in the candy maker’s top-selling candy bar.


An examination of all the submitted items, including opened and unopened candy bar samples, was performed utilizing a Zeiss Stemi 200-C stereomicroscope.

In order to look for glass on the interior of the candy bar, portions were excised from the bar and each portion was thinly sliced into a series of sections and examined by stereomicroscope. Sections were then dissolved and decanted through a sieve. The insoluble particles collected on the sieve were examined by stereomicroscope and polarized light microscopy (PLM) utilizing an Olympus BHSP microscope.


No glass was detected in any of the analyzed items. The case was dropped.
