N2 - By taking advantage of an exceptionally wide range of glass formation made possible by adding Al2O3 to the Na2O‐B2O3 binary system, the presence of a maximum in specific conductivity, not predicted by weak‐electrolyte models, was demonstrated at –55% Na2O. The decoupling of conducting modes from viscous modes in the supercooled liquid, assessed at Tg, reaches a maximum at 45% Na2)O. A second regime of increasing conductivity at >60% Na2O seems to be associated with incipient compound crystallization.
