Fracture resistance of technical quartz and normal window glasses was investigated in testing polished rectangular parallelepipeds
by edge flaking their long edges with Rockwell and Vickers indenters (EF method) and by scratching the specimen surface with
a Rockwell indenter followed by flaking its edge (S+EF method). It was established that the fracture of those glass specimens
in their edge flaking with a Rockwell indenter was started with the formation of a Hertzian ring crack and their corresponding
chip scars had the form of Hertzian “quasi-cones.” Fractographic data were used in analysis of test results.
