The invention relates to a glass pane comprising intentionally-provided break zones. The inventive pane is obtained using a method involving the localised overheating of the structure of the pane using an energy beam which penetrates same. During said method, the intentionally-provided break zones (5) are produced by sequentially guiding the beam along a pre-determined path (line 3) corresponding to the desired pane (1) break line and by sequentially focusing the beam along the length of said path (line 3) and at different depths in relation to the surface of the pane (1). According to the invention, the beam is sequentially focused at different penetration depths along a line which is inclined and/or curved in relation to the normal to the surface of the pane, such that a weakened structure is created in the pane in order to produce a different pane (1) break behaviour according to the direction of the stress which causes the break. |
