“…There are few computer programs that can calculate the viscosity curve as a function of temperature and other physical properties based on the chemical composition of a glass by a linear multiple regression using a large database of properties determined for a number of different glasses [23][24][25]. One of the main databases used for prediction of glass properties is the SciGlass Information System, which contains property data for hundreds of thousands of glasses (more than 230,000 glasses in version SciGlass-6.0) [25][26][27]. The SciGlass program gives highly reliable predictions of composition dependencies of glass properties based on statistical analysis of available information on a selected property and glass-forming system [27].…”
