The chemical durability of 30 glasses from the Na{sub 2}O {center_dot} B{sub 2}O{sub 3} {center_dot} SiO{sub 2} {center_dot} Al{sub 2}O{sub 3} {center_dot} Fe{sub 2}O{sub 3}{center_dot}CaO system was examined. Two standard leach tests, MCC-1P and PCT, were performed in unbuffered, deionized water. PCT tests were performed for durations up to twenty-four weeks to obtain glass dissolution rate data. Short-term MCC-1P test leachate solutions are determined by the glass composition. Long-term glass dissolution rates, however, are dependent on glass structure in addition to glass composition. The applicability of the free energy of hydration and other dissolution and durability models to this system is discussed.
