Claim:
1. A method of making shaped glass articles, comprising: placing a glass sheet on a mold having a shaping surface with a desired surface profile of a shaped glass article; heating the glass sheet by radiation having a wavelength in a range from about 2.7 microns and about 4.5 microns while the glass sheet is in the vicinity of the mold so that the mold remains substantially cooler than the glass sheet during the heating; conforming the glass sheet onto the shaping surface of the mold when a difference in temperature between the glass sheet and mold is at least 100° C. and less than 250° C. so that at least a portion of the glass sheet assumes the desired surface profile; and removing the glass sheet having at least a portion that assumes the desired surface profile from the mold.
