STRENGTHENED GLASS ARTICLES, EDGE-STRENGTHENED LAMINATED GLASS ARTICLES, AND METHODS FOR MAKING THE SAME

摘要

A method of manufacturing a laminated glass article is disclosed that includes forming a laminated glass article with at least one glass cladding layer and a glass core layer adhered to the glass cladding layer. The glass core layer is amenable to crystallization and optionally has a viscosity amenable to forming by a fusion lamination method. The method further includes removing a portion of the laminated glass article such that the glass core layer is exposed on at least one edge of the laminated glass article, and crystallizing at least a portion of the exposed glass core layer. A crystallized or semi-crystallized surface of the exposed glass core layer has a lower CTE than a remainder of the glass core layer. A laminated glass article and a glass article having a crystalline or semi-crystalline surface portion that is integral with a bulk of the glass body are also disclosed.
