    Abstract: According to one embodiment, a method for thermally treating glass articles may include holding a glass article at a treatment temperature equal to an annealing temperature of the glass article ±15°C for a holding time greater than or equal to 5 minutes. Thereafter, the glass article may be cooled from the treatment temperature through a strain point of the glass article at a first cooling rate CR1 less than 0°C/min and greater than -20°C/min such that a density of the glass article is greater than or equal to 0.003 g/cc after cooling. The glass article is subsequently cooled from below the strain point at a second cooling rate CR2, wherein |CR2| > |CR1|.

    Abstract: Methods are disclosed for treating zircon containing forming structures e.g. zircon isopipes with one or more treatment glass compositions in which defect causing reactions between the zircon of the forming structure and molten glass are suppressed at the delivery temperature of the treatment glass. The treatment compositions can be used during start up of a forming structure between runs of the same production glass on a given forming structure and/or when transitioning between runs of two production glasses on a given forming structure. The treatment compositions can be used with production glasses that are ion exchangeable.

    Abstract: A glass having from greater than or equal to about 0.1 mol.% to less than or equal to about 20 mol.% Ho2O3, and one or more chromophores selected from V, Cr, Mn, Fe, Co, Ni, Se, Pr, Nd, Er, Yb, and combinations thereof. The amount of Ho2O3 (mol.%) is greater than or equal to 0.7(CeO2 (mol.%) + Pr2O3 (mol.%)+ Er2O3 (mol.%)). The glass can include one or more fluorescent ions selected from Cu, Sn, Ce, Eu, Tb, Tm, and combinations thereof in addition to, or in place of the chromophores. The glass can also include multiple fluorescent ions.
