Claim 0:
1. A method for processing glasses, comprising the steps of:
providing a sheet glass element having two opposite parallel faces, an edge connecting the two faces, and a thickness between the two faces of not more than 700 micrometers; and
processing at least one edge of the sheet glass element to produce an edge surface portion that is convexly curved, so that at least one of the faces merges into the edge surface portion, wherein the edge surface portion has a curved arc with a length that is at least 1/30 of the thickness, the processing step comprising:
using at least one moving abrasive tool with a geometrically undefined cutting edge, and
increasing the radius of curvature and introducing furrows into the edge surface portion so that the furrows intersect each other,
wherein the furrows have a length that is greater than a width and a depth thereof, and
wherein the furrows extend obliquely or perpendicularly to each other.
