A composition for glass, alkaline earth aluminosilicate glass, and a preparation method therefor and applications thereof. Based on the total number of moles of each component and the counting of oxides, the composition contains 68-73 mol % of SiO, 11.5-15 mol % of AlO, 2-6 mol % of MgO, 2.5-7.5 mol % of CaO, 0-3 mol % of SrO, 2-7 mol % of BaO, 0-4 mol % of ZnO and 0.05-1.5 mol % of TiO. The glass has a high strain point, a high Young's modulus, a high specific modulus, a high Vickers hardness, high chemical stability, a high refractive index and high glass formation stability, and has a lower forming temperature, a lower melting temperature, a lower thermal expansion coefficient, a lower surface tension, a lower density, and low glass manufacturing difficulty.
