Methods for strengthening edges of a laminated glass article comprising a glass core layer positioned between a first glass clad layer and a second glass clad layer are disclosed. The methods may comprise polishing the cut edges of the laminated glass article with a slurry of polishing media applied to the edges of the laminated glass article with brushes. An edge strength of the laminated glass article is greater than or equal to about 400 MPa after polishing.

Chemically-strengthened thin glass having modified curvature and a method for making the same. The method includes providing a thin glass substrate which has host alkali ions situated in its surface regions, and possesses a treatment-advantaged surface region and a treatment-disadvantaged surface region located opposing each other; conducting a step of ion-exchange with invasive alkali ions having an average ionic radius larger than the average ionic radius of the host alkali ions, thereby producing a chemically-strengthened substrate which is characterized by an undesired curvature (warpage), and then conducting a step of reverse ion-exchange with reversing alkali ions having an average ionic radius equal to, or smaller than, the average ionic radius of the host alkali ions before ion-exchange, so as to produce a chemically-strengthened substrate having either less curvature or having a predetermined profile of curvature, which is not present in the chemically-strengthened glass substrate prior to reverse ion-exchange.

A glass ribbon includes a first major surface extending along a first plane. The glass ribbon includes a second major surface extending along a second plane substantially parallel to the first plane. A first thickness is defined between the first major surface and the second major surface along a thickness direction perpendicular to the first major surface. The first thickness is within a range from about 25 m to about 125 m. An edge surface extends between the first plane and the second plane. The edge surface comprises a height in the thickness direction that is less than the first thickness. Methods of manufacturing a glass ribbon are also provided.
