1. A method of manufacturing a partially textured glass article comprising:
a) providing a partially textured mother glass substrate having a first main surface and a second main surface which are opposed to each other wherein the partially textured mother glass substrate has a plurality of spaced apart partially textured zones on the first or second main surface with each zone corresponding to a partial texture for a corresponding glass article,
b) irradiating the first main surface of the mother glass substrate with a laser to form, on the first main surface, at least one separating line defining contour lines and extending in a depth direction from the first main surface to the second main surface, for dividing the partially textured glass article from the glass substrate, the partially textured glass article being a size smaller than a size of the mother glass substrate, and
c) separating the partially textured glass article from the mother glass substrate according to the separating line,
wherein texturing of the partially textured mother glass substrate is created by removal of material from the first or second main surface of the mother glass substrate.
