The present invention provides a silicate glass that can reduce a color change in base material zirconia even when simultaneously fired with an unsintered zirconia. The present invention also provides a dental product using same. The present invention relates to a silicate glass comprising: 65.0 to 90.0 mol% SiO2, 4.0 to 15.0 mol% Al2O3, 1.0 to 10.0 mol% K2O, 0.1 to 7.0 mol% Na2O, and 0.01 to 15.0 mol% CaO, the silicate glass being essentially free of B2O3, and satisfying the relation {(number of moles of Al2O3)/(total number of moles of RO + R2O)} ≥ 0.70, wherein R in the metal oxide represented by RO represents a metallic element in group 2 or 12 of the periodic table, and R in the metal oxide represented by R2O represents a metallic element in group 1 of the periodic table. The present invention also relates to a composite comprising the silicate glass and a base material formed of a ceramic; a sintered body as a fired product of the composite; and a dental product comprising the sintered body.
