Mathematical relationship for ingredients for fiber glass compositions are used to identify properties of the glass. In particular the forming temperature and delta T. In one embodiment, the mathematical relationship of the ingredients is of a generic quaternary SiO2, CaO, Al2O3 and MgO glass system. The relationship of SiO2, CaO, Al2O3 and MgO of interest include RO=CaO+MgO, SiO2/CaO, SiO2/RO, SiO2/Al2O3; Al2O3/CaO; SiO2+Al2O3; SiO2?RO and Al2O3/RO or RO/Al2O3. when other ingredients or components are added to the glass batch materials to alter the form...
