Japanese scientists create super-strong glass, but don't call it 'unbreakable'

Rumors of a truly unbreakable glass breakthrough are greatly exaggerated.

In late October, scientists in Japan revealed that they had successfully developed a new form of oxide glass that is as strong as cast iron and, by one metric, even stronger than Corning’s Gorilla Glass 4

In a study published in the journal Nature Scientific Reports, University of Tokyo scientists described using aluminum oxide (a fairly common glass-making material), tantalum oxide and a new manufacturing process to create a colorless, transparent glass with a hardness "comparable to the previously reported highest values for oxide glasses."
