We disclose glass compositions having an index of refraction of about 1.550 in the fiber form. Textile glass fibers formed from these glass compositions are especially useful for the reinforcement of clear plastics.
A fiberizable, boron and fluorine free glass composition having a liquidus temperature of 2200°F or less, having a viscosity of log 2.5 poises at 2450°F or less and having an index of refraction of about 1.550 in the fiber form, consisting essentially by weight of: - Ingredients Weight Percent ________________________________ SiO2 66.0 to 67.0 CaO 10.0 to 11.0 Na2O 14.5 to 15.5 ZrO2 7.5 to 8.5. ________________________________
