A method of forming high strength glass fibers in a refractory lined glass melter is disclosed. The refractory lined melter is suited to the batch compositions disclosed for the formation high modulus, and high-strength glass fibers. The glass composition for use in the method of the present invention is up to about 70.5 Weight % SiO2, 24.5 weight % Al2O3, 22 weight % alkaline earth oxides and may include small amounts of alkali metal oxides and ZrO2. Oxide based refractories included alumina, chromic oxide, silica, alumina-silica, zircon, zirconia-alumi...
We claim: 1. A process for producing glass fibers from raw glass batch in a refractory lined glass melter, the process comprising the steps of: charging raw glass batch to the melting zone of the glass melter, the glass batch comprising: about 60.5 to about 70.5 weight percent SiO2; about 10 to about 24.5 weight percent Al2O3; about 15.0 to about 20.0 weight percent RO, where RO equals the sum of MgO, CaO, SrO and BaO in the batch composition, 5 to 11.33 weight percent of the RO being MgO; and about 0 to about 3 weight percent alkali metal oxides; heat...
