FIELD: chemistry.
SUBSTANCE: glass for producing continuous glass fibre contains components in the following ratios, wt %: SiO2 50.0-60.0; Al2O3 10.0-20.0; CaO 12.0-16.0; MgO 6.0-10.0; TiO2 4.0-10.0; R2O (Na2O+K2O) 0.1-0.7; ZrO2 0.01-0.4; Fe2O3 0.01-0.5, wherein the glass has a low upper limit crystallisation temperature of 1240°C and first hydrolytic class chemical resistance.
EFFECT: high useful time coefficient of the process of forming fibre and low drop breakage, high efficiency of the glass-melting vessel.
