LionGlass named after Penn State's mascot is a new type of glass engineered by researchers at Penn State that requires significantly less energy to produce and is much more damage resistant than standard soda lime silicate glass. With LionGlass, the melting temperatures are lowered by about 300 to 400 degrees Celsius, which leads to a roughly 30% reduction in energy consumption compared to conventional soda lime glass. LionGlass is at least 10 times as crack-resistant compared to standard soda lime glass, which forms cracks under a load of about 0.1 kilograms force. Since LionGlass is 10 times more damage resistant than current glass, it could be significantly thinner.
I'd guess this glass gains self-healing behavior against scratches, because it's actually in state of high viscosity ("rubbery state") rather than vitrification. These advantages will undoubtedly come with many disadvantages, like the price of materials and/or low chemical resistance. The problem of many hyped progressivists technologies is, they just dissolve the cost of energy in another areas of industry (raw sources, maintenance and damage control etc.) - so that no actual net savings are provided at the end.

The article leaves out some important properties such as hardness and scratch resistance.
The problem is, few details about LionGlass are available as the research has not been published in a peer-reviewed journal yet and the team have only recently filed a patent application. LionGlass isn’t just one type of glass; it’s a whole family of glass compositions. The recipe is thus a secret until the patent is approved.
