Delamination Revealed

Comparison of delaminated flakes from a borosilicate container and absence of delamination in Corning Valor® Glass. An accelerated lamellae formation (ALF) technique, first published in The PDA Journal (2014) by C. Sloey, C. Gleason and J. Phillips was used to produce the delaminated borosilicate glass flakes in this video.

You didn't fill the vials to the same level. Underfilling enhances delamination potential. Even were that not the case, prudence and desire for consistent variables would suggest that you ought to ensure both vials contain the same volume of liquid. Valor glass may be amazing, but this test was not a valid comparison of borosilicate glass and valor glass.

[@giottolaudo7672]

If you simply wanted to demonstrate that borosilicate glass could produce lamellae, you could have simply left out the valor glass container. By including it, and pointing out that it [valor glass] had not produced lamellae, you turned it into a comparison video between the two products. But demonstrating that agitating two containers with different amounts of liquid in them can produce different results...is not really impressive or surprising.

this is a corporate ad video produced for ignorant christian trust fund investors and is not meant to replace the non profit university science studies or government regulation - pretty much like any other video on youtub

why does the glass delaminate inside the vial? is the chemical inside attacking it?

[@saucybackport]

cheap glass has small cracks on microscopic level that can lead to glass flaking even without any aggressive substances - Corning business is charging extra price mark up on glass that has little to no cracks and there for nor delamination
