Corning demonstrates glass-strength testing methods with Gorilla Glass

Corning has a new video up showing some of its testing methods. The video is clearly aimed at a broad audience and promoting Gorilla Glass, so don’t expect to see a lot of details and technical explanation. But the video offers brief demonstrations of how GG compares with competing products and ordinary glass using:

  • A ball drop test (128 gram and 535 gram steel balls dropped from a one meter height);
  • Abraded ring-on-ring test on 1.0 mm and 0.8 mm glass;
  • Vickers microindentation test;
  • A three-point flexibility test on 0.7 mm glass;
  • Knoop indenter microindentation hardness test; and
  • A ball launch.

    Dear Madam, dear Sir,
    Has the Gorilla glass something to do with the double ion-exchanged process developped at Penn-State University if I am correct?
    Cheers and thanks for the nice video,
    Gilles
