While techniques like tempering and laminating can help reinforce glass, they are costly and no longer work once the surface is damaged. “Until now there were trade-offs between high strength, toughness, and transparency. Our new material is not only three times stronger than the normal glass, but also more than five times more fracture resistant,” says Allen Ehrlicher, an Associate Professor in the Department of Bioengineering at McGill University.
