Abstract: A method for determining crystal phases of a glass ceramic sample, including the steps of applying energy to the sample using an excitation source, detecting raw Raman spectral energy that is given off by the sample using a detector, wherein the raw Raman spectral energy includes peak values, determining a plurality of predetermined energy peaks based off a composition of the sample, superimposing the plurality of predetermined energy peaks over the raw Raman spectral energy, applying a baseline value between each predetermined energy peak, subtracting the baseline value from the raw Raman spectral energy, calculating corrected peak values based on the raw Raman spectral energy and baseline value, and determining the crystal phases of the glass ceramic sample based on the corrected peak values.

Abstract: A method of reworking lithium containing ion exchanged glass articles is provided. The method includes a reverse ion exchange process that returns the glass article to approximately the composition of the glass from which the glass article was produced, before being subjected to ion exchange. The reworked glass articles exhibit a K2O concentration profile comprising a portion wherein a K2O concentration increases to a local K2O concentration maximum.

Abstract: A method for treating a mold includes grinding an outer metal surface of a mold body of the mold with a first material; lapping the outer metal surface after the grinding with a second material that is finer than the first material; and polishing the outer metal surface after the lapping to achieve an average surface roughness (Ra) less than or equal to about 0.15 μm and a waviness height (Wa) less than or equal to about 100 nm. A mold for shaping glass-based material can include a mold body having an outer metal surface, wherein the outer metal surface has an average surface roughness (Ra) less than or equal to about 0.15 μm and a waviness height (Wa) less than or equal to about 100 nm.

Abstract: A method includes contacting a second layer of a glass sheet with a forming surface to form a shaped glass article. The glass sheet includes a first layer adjacent to the second layer. The first layer includes a first glass composition. The second layer includes a second glass composition. An effective viscosity of the glass sheet during the contacting step is less than a viscosity of the second layer of the glass sheet during the contacting step. A shaped glass article includes a first layer including a first glass composition and a second layer including a second glass composition. A softening point of the first glass composition is less than a softening point of the second glass composition. An effective 108.2 P temperature of the glass article is at most about 900° C.
