    • To provide a colored glass plate of which the mass ratio of divalent iron as calculated as Fe2O3 to total iron as calculated as Fe2O3 can be stably maintained at a high level while amber coloring derived from salt cake (Na2SO4) is suppressed by reducing the amount of salt cake used as a refining agent, and which has less bubbles regardless of a small amount of total sulfur as calculated as SO3. A colored glass plate which is made of alkali-containing silica glass containing iron, tin and sulfur, wherein, as represented by mass % based on oxides, the proportion of total sulfur as calculated as SO3 is less than 0.025%, the proportion of divalent iron as calculated as Fe2O3 to total iron as calculated as Fe2O3 is at least 45%, the proportion of divalent tin as calculated as SnO2 to total tin as calculated as SnO2 is at least 0.1% as represented by mol %, and β-OH is at least 0.15 mm−1.
