Claim:
1. A method of forming a shaped glass article, comprising: placing a glass sheet on a mold having a mold surface with a select shaped glass article profile, the placing being such that a first glass area of the glass sheet corresponds to a first mold surface area of the mold surface, wherein the first mold surface area is substantially flat, and a second glass area of the glass sheet corresponds to a second mold surface area of the mold surface, wherein the second mold surface area comprises a bend; heating the first glass area and the second glass area to a glass viscosity between 10 locally heating the second glass area to a glass viscosity at or below 10 applying a force to the glass sheet by creating vacuum at the second glass area through at least one vacuum opening located in the bend to conform the glass sheet to the mold surface when the second glass area is at a glass viscosity at or below 10 locally cooling the first mold surface area using a cooling chamber positioned underneath the first mold surface area so that it does not extend underneath the bend to induce a thermal gradient on the mold surface that results in the glass viscosity in the first glass area remaining above 10
