<p>The invention is directed to a high strength, chemically toughened protective glass article, the glass article having a high damage tolerance threshold of at least 1500 g as measured by the lack of radial cracks when the load is applied to the glass using a Vickers indenter; preferably greater than 2000 g is measured by the lack of initiation of radial cracks when the load is applied to the glass using a Vickers indenter</p> |
