Room Temperature Glass Density Calculation (Full text article)
Alexander Fluegel: "Global Model for Calculating Room-Temperature Glass Density from the Composition"; J. Am. Ceram. Soc., vol. 90, no. 8, August 2008, p 2622-2625.
A large silicate glass density database including 6719 compositions, obtained from SciGlass and other published sources was systematically analyzed for agreement among room temperature density data reported in the literature in 1030 different studies from various investigators. It was found that the literature data agree very well. Using just 101 of the initial 6719 degrees of freedom 99.8% of the measured density data variance could be reproduced by an empirical polynomial model. The standard error of the developed model was 0.019 g/cm3.

Among the model outliers, 571 are possibly caused by inaccurate data reported by the authors in the original literature or by copying the original data wrongly into the SciGlass 6.7 database. A list of the 571 possibly erroneous density data is provided here (240 kB).
