Glasses were prepared by rice husk ash (RHA) from Suphan Buri Province, Thailand. RHA was composed of SiO 2 (95.932%), can be used instead of sand in the glass production. The glasses doped with CuO and composition of (40-x)SiO 2 (use RHA as SiO 2 ): 20B 2 O 3 : 25Na 2 O: 15CaO: xCuO where x is 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 mol%. The density and refractive index of the glasses trend increases, while the molar volume trend decreases with the increasing of CuO concentration. The absorption bands were showed with the peaks around 774 nm ( 2 B 1g → 2 B 2g ). The color coordinate in CIE L*a*b* system confirmed the blue color in glasses was obtain by adding the CuO.
