An executive from glass maker Corning (NYSE:GLW) took the stage at the Morgan Stanley Technology, Media, and Telecom Conference on Tuesday to say that the company’s Gorilla Glass is a better material to be used in consumer electronics than sapphire crystals. Rumors have been swirling that Apple (NASDAQ:AAPL) is planning to switch to sapphire for the display in the next iPhone, as the company has recently purchased a sapphire manufacturing plant in Arizona to make the scratch-resistant material.

Tony Tripeny, a senior vice president at Corning, spoke to analysts about the sapphire issue at the conference. “When we look at it, we see a lot of disadvantages of sapphire versus Gorilla Glass. It’s about 10 times more expensive. It’s about 1.6 times heavier. It’s environmentally unfriendly. It takes about 100 times more energy to generate a Sapphire crystal than it does glass. It transmits less light, which it means either dimmer devices or shorter battery life. It continues to break.

“I think while it’s scratch-resistant product, it still breaks, and our testing says that Gorilla Glass, about 2.5 times more pressure that it can take than Sapphire on. So when we look at it, we think from an overall industry and trend that is not attractive in consumer electronics,” he said in response to a question about how the rising popularity of sapphire would affect Corning and electronics consumers, per Seeking Alpha.

Analysts went on to ask Tripeny why sapphire has become the hot new material to use in electronics besides being slightly more resistant to scratches. “It has got a very sexy name,” Tripeny said. “Marketing matters.”
