In this research work, physical and optical properties on glass prepared from rice husk ash (RHA) doped with MnO2 glasses were in investigated. RHA was sintered at 1,000 °C and use as a silica source for glass production. The glass sample were prepared and doped with different concentrations of MnO2 ranging from 0.0 to 1.0 mol%. The results are shown that the colors of glass samples were altered from colorless to brown with increasing of MnO2 concentration. Refractive index and density were increased with increasing MnO2 concentration. The absorption peaks at 440 nm were obtained for all Mn doped glasses.
