A method is provided for scoring glasses. The method includes the steps of generating a deep crack in the glass along an intended separation line by exerting pressure onto the glass surface using a rigid scoring tool, wherein the scoring tool, by being pressed against the glass surface and due to the advancement force while introducing the deep crack generates a zone of elastic strain in the glass in a direction along the glass surface and perpendicular to the separation line, which extends in an arc in the plane defined by the separation line perpendicular to the glass surface such that one leg of the arc is located close to the contact point of the scoring tool on the glass surface and another leg is located inside the glass. The arc being open towards the advancement/advancement direction of the scoring tool.
