METHOD AND APPARATUS FOR FORMING SHAPED GLASS ARTICLES

A method of forming a shaped glass article includes placing a glass sheet on a mold such that a first glass area of the glass sheet corresponds to a first mold surface area of the mold and a second glass area of the glass sheet corresponds to a second mold surface area of the mold. The first glass a...

Summary:A method of forming a shaped glass article includes placing a glass sheet on a mold such that a first glass area of the glass sheet corresponds to a first mold surface area of the mold and a second glass area of the glass sheet corresponds to a second mold surface area of the mold. The first glass area and the second glass area are heated such that the viscosity of the second glass area is 8 poise or more lower than the viscosity of the first glass area. A force is applied to the glass sheet to conform the glass sheet to the mold surface. During the heating of the second glass area, the first mold surface area is locally cooled to induce a thermal gradient on the mold.
