Abstract: Glass-ceramics exhibiting a Vickers indentation crack initiation threshold of at least 15 kgf are disclosed. These glass-ceramics may be ion exchangeable or ion exchanged. The glass-ceramics include a crystalline and amorphous phases generated by subjecting a thin precursor glass article to ceramming cycle having an average cooling rate in the range from about 10° C./minute to about 25° C./minute. In one or more embodiments, the crystalline phase may comprise at least 20 wt % of the glass-ceramics. The glass-ceramics may include β-spodumene ss as the predominant crystalline phase and may exhibit an opacity ≥ about 85% over the wavelength range of 400-700 nm for an about 0.8 mm thickness and colors an observer angle of 10° and a CIE illuminant F02 determined with specular reflectance included of a* between −3 and +3, b* between −6 and +6, and L* between 88 and 97.

Abstract: Locally cerammed optically transparent glass-ceramic articles for consumer products. The locally cerammed glass-ceramic articles may have one or more primary glass-ceramic regions including primary crystal phases of a glass-ceramic material and one or more secondary glass-ceramic regions including secondary crystal phases of the glass-ceramic material. The primary glass-ceramic region(s) may be optically transparent and the secondary glass-ceramic region(s) may be non-optically transparent. The primary glass-ceramic region(s) may have a fracture toughness less than the fracture toughness of the secondary glass-ceramic region(s).

Abstract: A group of glass compositions in the Li2O—Al2O3—SiO2—B2O3 family that can be chemically strengthened in single or multiple ion exchange baths containing at least one of NaNO3 and KNO3 for a short time (2-4 hours) to develop a deep depth of layer (DOL). In some instances, the DOL is at least 70 μm; in others, at least about 100 μm. The ion exchanged glasses have a high damage resistance (indentation fracture toughness ranging form greater than 10 kgf to greater than 50 kgf) that is better than or at least comparable to that of sodium aluminosilicate glasses.
