This research work has been developed the deep blue colored glasses in soda lime glass systems doped with different CoO content by using glass waste as the substance and has been studied their physical and optical properties. The results showed that density and refractive index values tended to be increased along with increasing of CoO content. Whereas, the molar volume decreased with increasing of CoO content in glass matrix. The absorption spectra of glass sample showed three absorption peaks at wavelengths of approximately 525, 625 and 725 nm. The emission spectra of the glasses were illustrated the highest emission intensity at 613 nm wavelength. Moreover, the color of glasses associated with the parameter in the CIE L^*a^*b  color coordinate. Hence, the results from this research could imply as a new way to recycle household glass waste and also helpsreduce the amout of glass waste.
