Abstract: A method is described for strengthening or restoring strength to a flat brittle oxide substrate (12) which includes the steps of coating the edges of the brittle oxide substrate (12) with a strengthening composition without coating a significant portion of the major flat surfaces of the substrate (12). The strengthened brittle oxide substrate (12), such as glass, and a window containing as a window pane the edge strengthened glass (12) are also provided.
