(a) Vickers hardness (HV) values are reported as mean ± 1σ from 10 indentations for 100, 200 and 300 gf and (b) Crack formation probability as a function of the indentation load, as expressed in Newton, in basaltic glass B3 (green circles), crystallized with annealing at 850 °C for 3 h (B3_180, grey triangles) and that with two-step treatment 1 h at 750 °C + 3 h at 850 °C (B3_180+, red diamonds). Labels correspond to the critical load (Pc) for each sample.
