1. A chemist at Corning accidentally created what would become Gorilla Glass in 1952 when a furnace overheated by 300 degrees, producing the world’s first synthetic, shatterproof glass-ceramic. A decade later, the company’s researchers bolstered its composition with aluminum oxide, then treated it to a scorching salt bath, which shoves aside small sodium ions in favor of larger potassium ions.

2. The same glass that shields smartphones is also whizzing around the speedway in the windshield of Ford’s GT race cars, tucked beneath a layer of conventional glass. In tests, the hybrid material withstood the force of a 1.75-inch hailstone hurled at 55 mph from an ice canon.

3. The latest version, Gorilla Glass 6, first graced ­smartphones from Chinese brand Oppo in August. In preparation, Corning battered glass swatches in handbag simulators filled with scratchy items and dumped them onto 180-grit sandpaper to mimic concrete. Corning claims GG6 can survive an average of 15 drops from a selfie height of 1 meter; meanwhile, the shattered-screen-toting masses are withholding judgment.
