摘要:
The present invention provides a glass composition in which a smaller amount of arsenic oxide or antimony oxide that has a heavy burden on the environment is used and fewer bubbles remain. This glass composition includes, in terms of mass %: 40 to 70% of SiO2, 5 to 20% of B2O3, 10 to 25% of Al2O3, 0 to 5% of MgO (up to and not including 5%), 0 to 20% of CaO, 0 to 20% of SrO, 0 to 10% of BaO, 0 to 1.5% of Li2O, 0 to 1.5% of Na2O, 0 to 1.5% of K2O, and 0 to 1.5% of Cl. The sum of the contents of Li2O, Na2O, and K2O is 0.05 to 1.5 mass %, and the content of K2O is equal to or larger than that of Na2O.
