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.
