| Abstract: | In base glasses containing (a) Na2O 16, CaO 10, and SiO2 74% and (b) Na2O14, CaO 12, and SiO2 74%, MgO was substituted in steps of 2% for CaO. The effects of the substitution on liquidus temperature, viscosity, fiber softening point, and the resistance of the glasses to dilute acid and to distilled water are described. |
