Video: How Apple plans to make its own scratch-proof glass

Take a tour of a sapphire crystal factory like the one Apple is building in Arizona.

FORTUNE -- Never heard of GT Advanced Technologies (GTAT)?

Neither had we before Monday, when the New Hampshire-based crystal manufacturer announced that it had signed a multiyear contract with Apple (AAPL) to provide sapphire materials in Apple's new Mesa, AZ, factory.

As happens, we now know quite a bit about GT's technology for growing sapphire "boules," thanks to the good folks at Pocketnow who visited GT's Salem, MA, plant in April and videotaped the attached YouTube factory tour.

According to GT, iPhone screens made of sapphire could be even more scratch-resistant than the ones that now use Corning's (GLW) Gorilla Glass.

Thanks to Horace Dediu (@asymco) for the link.
