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.
