Abstract

A method of making a glass sheet includes providing a glass ribbon at a first temperature where at least a portion of the glass ribbon exhibits viscous behavior. A heat sink is provided adjacent to the at least a portion of the glass ribbon at a second temperature that is less than the first temperature. A plurality of heating elements is provided at a position where the heating elements are operable to shape a thermal profile of the heat sink. Heat is transferred from the at least a portion of the glass ribbon to the heat sink and at least a portion of the heat is absorbed into the heat sink.
