A method of reforming glass includes placing a glass sheet on a mold having a shaping surface for forming the glass sheet into a shaped glass article. A target starting mold forming temperature and temperature window are selected for the mold. A target starting mold forming temperature and temperature window are also selected for the glass sheet. The glass sheet and mold are simultaneously exposed to a first furnace condition controlled to a furnace temperature set point above the target starting mold forming temperature until a temperature of the mold is within the first temperature window. The glass sheet and mold are simultaneously exposed to a second furnace condition controlled to a furnace temperature set point between the target starting mold forming temperature and first furnace temperature set point until a temperature of the glass sheet is within the second temperature window, after which forming of the glass sheet starts.
