Lithium-containing polycrystalline ceramic sheets include grains having an average grain size of less than 5 μm, a relative density greater than 90%, and a thickness of up to 200 μm. In aspects, the lithium-containing polycrystalline ceramic sheets include an outer edge of the sheet that has no height variations greater than 1 mm from baseline in a perimeter trace. In aspects, the lithium-containing polycrystalline ceramic sheets include microstructural features of an outer edge of the sheet are no greater than about ⅓ the thickness of the sheet. In aspects, the lithium-containing polycrystalline ceramic sheets include an outer edge of the sheet that is enriched in lithium relative to a bulk of the sheet.

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.
