Abstract
An ultrathin chemically toughened glass article has a thickness of no more than 0.4 mm. In order to improve the sharp impact resistance, the glass article has a breakage height (given in mm) of more than 50 multiplied by the thickness (t) of the glass article (given in mm). Further, it has a breakage bending radius (given in mm) of less than 100000 multiplied by the thickness (t) of the glass article (given in mm) and divided by the figure of the surface compressive stress (in MPa) measured at the first surface.
