    Abstract: The efficiency of ion exchange processes is increased by increasing the concentration of nitrite salts in the molten salt bath. The increase in nitrite salt concentration may be achieved by adding a nitrite salt to a molten nitrate salt bath, aging a molten nitrate salt bath, or a combination thereof. The glass-based articles produced using the modified baths exhibit reduced haze and increased flexural strength

    Abstract: Methods for reducing a defective area in a strengthened substrate to produce a non-defective substrate are provided. The methods include contacting a strengthened defective substrate with a heated salt bath containing at least one monovalent salt, and removing the strengthened substrate from the bath. The strengthened substrate, before being contacted with the salt bath, is a defective substrate having at least one defective area and one or more non-defective area. Upon removal from the salt bath, at least one defective area has been reduced or substantially removed to produce a non-defective substrate.

    Abstract: A glass comprising a coefficient of thermal expansion (CTE) of 70×10−7/° C. or less, a liquidus viscosity of at least 150 kP, and Li2O in an amount of 0.1 wt. % or less, wherein the glass is ion-exchangeable. A glass, comprising SiO2 in an amount of 64-73 wt. %, Al2O3 in an amount of 7-15 wt. %, B2O3 in an amount of 9-11 wt. %, Na2O in an amount of 6-9.5 wt. %, K2O in an amount of 0.5-3 wt. %, CaO in an amount of at least 0.05 wt. %, and Li2O in an amount of less than 0.1 wt. %, wherein a weight ratio of Na2O/Al2O3 is less than or equal to 0.9. A method of recycling glass, the method comprising heating a composition to form a melt, the composition comprising glass cullet in an amount of at least 60 wt. %, and raw materials in an amount of 40 wt. % or less.
