In this research Cr₂O₃-SiO₂ and Cr₂O₃-TiO₂ green pigments have been fabricated using a mixture of Cr₂O₃-SiO₂ and Cr₂O₃-TiO₂ powder by ceramic method. The samples have been homogenized using planetary mill in a solvent with a ratio of 1:4 for 5 h and then printed on the ceramic using screen printing method and heated in the industrial condition. The crystal structure of samples, the shape and the size of the particles and their optical properties have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis spectroscopy and CIE L^*a^*b^* colorimetric methods. The XRD results show two-phase structure has been created in both samples. The average of crystallite size for Cr₂O₃-SiO₂ and Cr₂O₃-TiO₂ were measured 40 and 34 nanometers, respectively. The SEM images show that the average size of Cr₂O₃-SiO₂ and Cr₂O₃-TiO₂ are 290 and 143 nanometers, respectively. The physical properties of printed ceramic were investigated by SEM and colorimetric methods. The average particle size for printed samples, Cr₂O₃-SiO₂ and Cr₂O₃-TiO₂, on the ceramic were measured 131 and 106 nm respectively.
