Flexible Glass Can Bend without Breaking

Flexible Glass Can Bend without Breaking
A flexible, ultrathin glass able to bend without breaking could open the door to an array of new designs, including folding tablets and phones.

Created by the German glassmaker Schott, the glass is thinner than a human hair, and can be manufactured in sheets one kilometer longs. Although the glass won’t fold yet—though the developers believe that innovation is right around the corner—it can flex like plastic and can support electronics. The glass has been made stronger using an ion exchange technique, which replaces the smaller sodium ions with potassium ions, resulting in compression within the glass—“the more it is squeezed, the stronger it gets.”
