A heavy metal-free glass developed by Corning will trim production & recycling costs at a time when prices for super-thin screens used in LCD TVs are falling sharply. The Eagle XG glass is the first in the LCD industry to be completely free of arsenic as well as other heavy metals such as barium & antimony & halides that can produce potentially harmful byproducts during manufacture, the company announced.

"It reduces the overall cost all the way from digging stuff out of the ground to end of life of the display." Arsenic "is really a magic element to melt a high-temp/high-performance glass & get it free of bubbles," he said. "Even an exquisitely small bubble of glass in an LCD screen can actually destroy it.
