Reproducible “complexed” Hertzian cones were formed in glass as a result of thermally induced tensile stresses. These cones differ from normal cones by having wavy profile patterns, indicating two modes of fracture operating alternately. One mode is shallow and the other steep, together averaging a crack angle of 18.9 ± 1°. The thermal technique offers new test conditions for studying Hertzian fracture.
