Claim 9:
10. The aluminosilicate glass according to claim 8, wherein:
an oxygen ion concentration Vo of the aluminosilicate glass is 0.08 mol/cm3 or more; and

Vo=[(2*NSi+3*NAl+3*NB+NMg+NCa+NSr+NBa+NZn+3*NNH4+3*NY+3*NLa+3*NLu)/(NSi+NAl+NB+NMg+NCa+NSr+NBa+NZa+NY+NLa+NLu)]/(mo/ρ),

wherein, based on 100 g of the obtained aluminosilicate glass:
NSi, NAl, NB, NMg, NCa, NSr, NBa, NZn, NY, NLa and NLu represent the amounts of substances of SiO2, Al2O3, B2O3, MgO, CaO, SrO, BaO, ZnO, Y2O3, La2O3 and Lu2O3, in the mixture M1, respectively;
NNH4 represents the amount of substance of NH4NO3 added into the mixture M1;
mo represents the mass of the aluminosilicate glass obtained after applying the melting treatment to the mixture M2, and has a unit of g; and
ρ represents the density of the obtained aluminosilicate glass, and has a unit of g/cm 3.
