Process for reinforcing glass objects, by producing a compression layer on the surface of the object, to reinforce it, characterized by comprising the treatment of said layer to increase the viscosity of the glass constituting it in comparison with the viscosity of the glass in the interior of the object, whereby the surface layer of the glass has a temperature of deformation point higher than the interior of the glass object, by then cooling the glass passing through its two points of deformation, whereby the surface layer of the glass solidifies before the inner glass, producing a compressive stress in the surface layer.
