Corning, the glass manufacturer that currently provides Apple with Gorilla Glass for its iPhones, is working on a bendable version of the glass that could be with us in less than two years. In an interview with Wired (via MacRumors), Corning general manager John Bayne said that the challenge was creating a glass that’s thin enough to bend without sacrificing the resilience needed to protect a display.

In 2017 Apple said it was investing $200 million in the company to “support Corning’s R&D, capital equipment needs, and state-of-the-art glass processing.” Patents filed by Apple suggest that it’s already investigating the area, while a report published last year claimed Apple could release a foldable device as early as 2020.
