Abstract
The invention relates to a glass having SiO2, Na2O and CaO as main components, which comprises two amorphous phases having different compositions, one of the two phases being in the form of inclusions dispersed in the volume of the other phase and comprising crystalline particles. Such a glass has good mechanical strength, in particular good resistance to scratch propagation and allows improved tempering. This glass furthermore has a pleasant aesthetic appearance.
