Zusammenfassung:	The disclosure provides a method for forming a hole in a glass or glass-ceramic sheets. The method includes scoring a major surface of a glass or glass-ceramic sheet to define the hole, placing the sheet on a cavity-containing receiving surface such that a peripheral edge of the cavity is positioned external to the area bounded by the first score, and fracturing the sheet along the score to break away the portion of the sheet defined by the first score. The method allows for the formation of large openings in thin glass sheets where the mother sheet is not broken or damaged by the formation of the opening.
