Abstract
Methods of manufacturing a glass-based article include exposing a glass-based substrate to a molten salt bath including a first salt and a second salt. In aspects, the first salt includes a metal ion that has a larger ionic radii than an alkali metal of the glass-based substrate and a first anion, and the second salt dissolved in the molten salt bath includes the same metal ion as the first salt and a second anion different from the first anion. In aspects, the first salt is potassium nitrate, the second salt is potassium carbonate, and a concentration of the potassium carbonate remains at or below its solubility limit in the molten salt bath.
