A method for ceramming a glass article to a glass-ceramic includes placing a glass article into a heating apparatus, and heating the glass article to a first hold temperature at a first predetermined heating rate. The glass article is held at the first hold temperature for a first predetermined duration. The viscosity of the glass article is maintained within log viscosity &#xb1;1.0 poise during the first predetermined duration. The glass article is then heated from the first hold temperature to a second hold temperature at a second predetermined heating rate. The glass article is held at the second hold temperature for a second duration. A density of the glass article is monitored from the heating of the glass article from the first hold temperature through the second duration, and the second duration is ended when an absolute value of a density rate of change of the glass article is less than or equal to 0.10 (g/cm)/min.
