Abstract
A glass sheet is placed on a mold and heated to a first temperature. The glass sheet is then formed into a glass article having a three-dimensional shape using the mold. An isothermal heat transfer device comprising at least one heat pipe is provided in thermal contact with the mold. With the glass article on the mold and the isothermal heat transfer device in thermal contact with the mold, the glass article, mold, and isothermal heat transfer device are transported along a thermally-graded channel to cool the glass article to a second temperature. During the transporting, the isothermal heat transfer device transfers heat from a relatively hot region of the mold to a relatively cold region of the mold.
