In this work, the effects of melting temperature (1200, 1300, 1400 and 1500 °C) on glass properties, prepared in the composition 64.4SiO2: 10.0CaO: 25.0Na2O: 0.6Fe2O3 have been investigated. The Fe2O3 doped glass shown green color due to the homogeneous distribution of Fe3+ and Fe2+ ions in the glass matrices. Refractive index, dielectric constant, optical dielectric constant and the reflection loss increases when the melting temperature is increased. The absorption bands are observed in the all spectra with the peaks around 380 and 435 nm are attributed to Fe3+ and board peak around 1,050 nm due to Fe2+. The Fe2+ peaks are increased with increasing of melting temperature, correspond with glass color.
