1. A method for ion exchanging glass articles, the method comprising:

adding fresh salt and solid additives to an additive chamber of an ion exchange tank;

applying heat to the additive chamber to form molten salt;

flowing the molten salt out of the additive chamber, through a flow channel of a weir system of the ion exchange tank, and into a processing chamber of the ion exchange tank; and

ion exchange processing at least one glass article in the processing chamber,

wherein the additive chamber comprises a solids-absorbing material disposed therein.
