There is a close correspondence between short range structure, determined spectroscopically, and physical properties in alkali borosilicate glasses. The density and glass transition temperature were measured in all alkali borosilicate glass systems for a very wide range of alkali concentrations, in families of glasses with constant silica to boron oxide ratios. The density data are compared with quantitative structural models as determined by the 11B NMR work of Bray and co-workers.
