"What we did here is find a very, very tough marginal glass made of palladium with small fractions of metalloids like phosphorus, silicon, and germanium, which yielded one-millimeter-thick samples. And we just said, let's add very little of something that will make it bulk without making it brittle," says Demetriou.Bravo, Dr. Demetriou of Cal Tech.
By adding 3.5 percent silver to this marginal glass, Demetriou was able to increase the thickness to six millimeters while maintaining its toughness.
