A bstract A review is given of the exchange of ions (1) in glasses containing water, (2) on the hydrated surfaces of ordinary glasses, and (3) in commercial glasses with and without the application of an electrical field, and it is shown that the ammonium ion offers unique features. It may be electrolytically introduced into soda glasses without impairing their structure as much as other ions. Because of the volatility of ammonium compounds, it may be removed easily, leaving a glass of higher silica content. Such glasses could be obtained in some experiments, but the soda probably cannot be entirely removed.
