Thanks in part to the strong performance of its specialty materials segment, shares of Corning Incorporated (NYSE:GLW) returned more than 40% in 2013.

In fact, during the most recent quarter, Corning's specialty materials sales and core earnings grew 8% and 23% sequentially -- an impressive result driven primarily by increased sales and manufacturing improvements for its popular Gorilla Glass product.

And lucky for investors, according to the Fool's Steve Symington in the following video, Corning has been hard at work on three key improvements to Gorilla Glass in an effort to maintain its momentum in 2014.

First, Steve says, Corning should benefit from the introduction of Gorilla Glass NBT, with which it plans to grab lucrative market share in larger touch-sensitive screens. Next, Corning is aiming to commercialize finished 3-D-shaped Gorilla Glass parts before the end of the year. Finally, Corning's new antimicrobial Gorilla Glass should prove yet another great differentiator as the world's first EPA-registered antimicrobial cover glass.
