Penn State’s New LionGlass Is 10X Tougher & Has Half The Carbon Emissions
We don’t focus much on the glass industry when we talk about cutting carbon emissions. We focus on transportation, electricity generation, cement production, shipping, and air travel, but overlook glass-making. And yet, manufacturing glass is responsible for aboutOn June 30, 2023, Penn State University announced, a new product that is ten times more resistant to damage than soda lime silicate glass and uses about half as much energy in the manufacturing process.
The majority of the carbon dioxide emissions come from the energy required to heat furnaces to the high temperatures needed for melting glass. With LionGlass, the melting temperatures are lowered by about 300 to 400 degrees Celsius. That in turn leads to about a 30% reduction in energy consumption compared to conventional soda lime glass.Not only is LionGlass easier on the environment, it’s also much stronger than conventional glass.
Mauro explained that crack resistance is one of the most important qualities to test for in glass because it is how the material eventually fails. Over time, glass develops microcracks along the surface, which become weak points. When a piece of glass breaks, it’s due to weaknesses caused by existing microcracks. Glass that is resistant to forming microcracks in the first place is especially valuable, he added.
