Glass element with cut edge and method of producing same

An apparatus for scoring glass, comprising:

• a rigid scoring tool that slides over a surface of the glass without rolling,
• wherein the rigid scoring tool has a vertex between three intersecting faces and an edge extending from the vertex, wherein one of the three intersecting faces is between the other two of the three intersecting faces and the one of the three intersecting faces is oriented at an angle between 40° and 50° from perpendicular to the surface of the glass,
• wherein the rigid scoring tool is oriented and placed in the apparatus so that the vertex defines a contact point to the glass and one of the three intersecting faces precedes in an advancement direction;
• a device for pressing the rigid scoring tool against the surface of the glass;
• and
• an advancement device for moving the rigid scoring tool and the glass relative to each other along a separation line to produce a crack in the glass by a pressure force of the rigid scoring tool at a contact point against the surface and an advancement force,
• wherein the rigid scoring tool is configured in the apparatus so that, under the pressure force and advancement force exerted when introducing the crack, a zone of elastic strain is produced in the glass with a first directional component of the zone of elastic strain parallel to the surface and perpendicular to the separation line, the zone of elastic strain extends in an arc in a plane defined by the separation line perpendicular to the surface so that one leg of the arc is located close to the contact point of the rigid scoring tool on the surface and another leg is located inside the glass, the arc being open towards the advancement direction of the rigid scoring tool.
