The mechanical strength of the glasses is determined by the strength of the established bonds between the different macro-anionic species, these bonds being the weaker compared to the covalent ones inside the macro-anionic species. In this paper is proposed a probabilistic relationship to calculate the theoretical mechanical strength of the SiO 2 glass and of some compositions in the Na 2 O⋅Si 2 system, in good agreement with literature data.
