The present disclosure is directed to methods and techniques for gob-pressing a glass part of challenging geometries, such as large surfaces with thin thickness as well as features positioned far from a centroid of the part.

Glass parts and gob-pressing methods for making such

A glass ceramic article including a lithium disilicate crystalline phase, a petalite crystalline phased, and a residual glass phase. The glass ceramic article has a warp (μm)<(3.65×10/μm×diagonal) where diagonal is a diagonal measurement of the glass ceramic article in μm, a stress of less than 30 nm of retardation per mm of glass ceramic article thickness, a haze (%)<0.0994t+0.12 where t is the thickness of the glass ceramic article in mm, and an optical transmission (%)>0.91×10of electromagnetic radiation wavelengths from 450 nm to 800 nm, where t is the thickness of the glass ceramic article in mm.

The glass ceramic article has a warp (&#x3bc;m)&#x3c;(3.65&#xd7;10/&#x3bc;m&#xd7;diagonal) where diagonal is a diagonal measurement of the glass ceramic article in &#x3bc;m, a stress of less than 30 nm of retardation per mm of glass ceramic article thickness, a haze (%)&#x3c;0.0994t+0.12 where t is the thickness of the glass ceramic article in mm, and an optical transmission (%)&#x3e;0.91&#xd7;10of electromagnetic radiation wavelengths from 450 nm to 800 nm, where t is the thickness of the glass ceramic article in mm.

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.

An article includes SiOfrom about 40 mol % to about 80 mol %, AlOfrom about 1 mol % to about 20 mol %, BOfrom about 3 mol % to about 50 mol %, WOplus MoOfrom about 1 mol % to about 18 mol % and at least one of: (i) Au from about 0.001 mol % to about 0.5 mol %, (ii) Ag from about 0.025 mol % to about 1.5 mol %, and (iii) Cu from about 0.03 mol % to about 1 mol %, and RO from about 0 mol % to about 15 mol %. The RO is one or more of LiO, NaO, KO, RbO and CsO. RO minus AlOranges from about &#x2212;12 mol % to about 3.8 mol %.

A method of processing a glass material includes guiding and/or focusing light from a light source to glass material in a hot stage of a processing system, where the light source provides light at a wavelength &#x3bb; that interacts with crystals that may be formed in the glass material. The method includes collecting and/or guiding light directed from the glass material in the hot stage to a wavelength separator, and separating the light directed from the glass material to provide a spectrum &#x3b4; having wavelengths that are within about twenty nanometers of the wavelength &#x3bb;. The method includes observing with a detector light of the spectrum &#x3b4; to identify nano-scale shifts in the wavelength &#x3bb; caused by interaction with crystals, if present, within the glass material in the hot stage of the processing system.
