A sodium boroaluminosilicate glass, in which no non-bridging oxygen could be detected, was contacted with silver nitrate-sodium nitrate melts at 375 degrees C. Fickian behaviour was observed up a degree of exchange of 70% and non-Fickian behaviour for a higher degree, with the appearance of structure relaxation processes.
