IPC: C03B32/02

Abstract: A method for forming glass ceramic articles includes heating a stack of glass sheets to a nucleation temperature to create a nucleated crystallizable stack of sheets; heating the nucleated crystallizable stack of glass sheets to a crystallization temperature; and maintaining the crystallization temperature for a predetermined period of time to produce the glass-ceramic articles. The stack of glass sheets has a mass index of less than or equal to 35.

Abstract: Glass stack configurations including a carrier plate, setter plates, and glass sheets for thermal treatment of the glass sheets to form glass ceramic articles are provided. The glass stacking configurations and components described herein are selected to improve thermal uniformity throughout a glass stack during ceramming processes while maintaining or even reducing the stresses in the resultant glass ceramic article. Accordingly, the glass ceramic articles made according to the various embodiments described herein exhibit improved optical qualities and less warp than glass ceramic articles made according to conventional processes. Various embodiments of carrier plates, setter plates, parting agent compositions, and methods of stacking glass sheets are described.
