  We report new time-resolved synchrotron x-ray diffraction (SXRD) measurements
to track structural transformations in calcium-aluminate (CaO)x(Al2O3)1-x
liquids during glass formation, and review recent progress in neutron
diffraction with isotope substitution (NDIS) experiments, combined with
aspherical ion model molecular dynamics (AIM-MD) simulations, to identify the
atomic-scale configurational constraints on glass-forming ability.
