Methods of enhanced ion exchange (IOX) include exposing a substrate to a bath mixture that includes a second salt dissolved in a first salt, the second salt includes the same metal ion as the first salt with an anion different from the first salt. The first salts are conventional nitrate salts into which one or more second salts, for example, carbonate, sulfate, chloride, fluorine, borate, or phosphate salts are dissolved. The second salts remain at or below their solubility limits in the first salts. Any poisoning ions remain at or below their solubility limits in the bath mixture. Glass-based articles made therefrom and electronic devices incorporating the glass-based articles are also disclosed.
