Abstract: A method of structuring a glass element having a first side face and a second side face is provided. The method includes the steps of: producing a filament-shaped flaw in the glass element with a pulsed laser beam along a focus line; etching to remove glass in the filament-shaped flaw to form a wall extending from the first side face towards the second side face, the wall having a boundary line that is tapered at a vertex between the wall and the first side face with a taper angle with respect to a perpendicular of the first side face; and adjusting the taper angle by controlling a feature of the focus line. The feature is selected from a group consisting of a position of the focus line, a length of the focus line, an intensity distribution of the focus line, and any combinations thereof.

Abstract: A chemically tempered glass or glass-ceramic article in pane form for use as a cover pane includes a glass or glass-ceramic having a composition comprising the components SiO2, Al2O3, Li2O and Na2O, having a thickness d of 300 μm to 1000 μm, a compressive strength at a distance of 30 μm from a surface of a main face CS30 of at least 60 MPa, and a compressive strength at a distance of 50 μm from the surface of a main face CS50. The compressive strengths CS30 and CS50 of the same main face are in the following ratio V to one another: V = CS 30 CS 50 ≤ - 0.0006 * d + 2 , where d is the thickness of the article in μm.
