The invention relates inter alia to a method for treating the surface of glasses which have, at least in a near-surface area, a higher molar alkali metal content than aluminum content. The method comprises the step of contacting the glass surface with metallic aluminum, whereby the temperature during contact with the aluminum ranges between 250°C below to 800°C above the transformation temperature of glass in the area of the surface to be treated. |
