Apple's Mesa sapphire plant to double "worldwide capacity"

The material requires furnaces to spark a reaction in which cylinders of sapphire grow over about a month, then can be sliced to less than a millimeter thick for use on gadget screens, said Eric Virey, an analyst with Yole Developpement, a research firm that studies the market.

Apple’s Mesa plant will make an “unprecedented” amount of synthetic sapphire, Virey said.

“When it’s operating at full capacity, this plant is going to be producing as much as two times the current worldwide capacity,” he said. The factory will be able to make enough sapphire for 80 million to 100 million iPhones a year, he said.


Sounds like the amount of sapphire one might need for an iPhone 6.
