The densitites of rapidly cooled lithium silicate glasses are reported. The composition varies over an exceptionally wide range of alkali concentrations, 0-64 mol% Li2O and J values of 0.0-1.8, where J is defined as the molar ratio of alkali oxide to silicon dioxide in the glass. These new findings are considered along with previous published data regarding this glass system, resulting in a density model based on short range molecular structure.
