High temperature viscosity and density of glass melts, glass transition temperature and thermal expansion coefficient of glasses from the system MgO-CaO-B2O3-Al2O3-SiO2 with composition close to the E-glass were measured and interpreted with respect to the effect of CaO and MgO content on their physical properties. The Andrade model was applied for description of the temperature dependence of the glass viscosity within studied temperature range.
