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.

Methods for forming glass ceramic articles

A process for transitioning molten glass in a glass furnace from one color to another color while minimizing the production of out-of-color specification transition glass. During the transition, a compensating agent is introduced into the molten glass to adjust the color of the molten glass being discharged from the furnace so that the discharged molten glass meets a target color specification, which effectively results in acceleration of the furnace color change compared to other conventional methods.

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.

A process for forming coating on an interior surface of a glass container. A glass preform is formed at blank molding station from a gob of molten glass. Thereafter, a glass container is formed at a blow molding station from the glass preform. A coating material comprising a suspension of nanoparticles in a liquid medium is introduced into an interior of the glass preform or the glass container while the glass is still hot from being formed. Heat from the glass is transferred to the liquid medium to vaporize the liquid medium and form a coating on an interior surface of the glass preform or the glass container. Thereafter, the glass container is annealed.
