Abstract: The beige pigment based on (Fe, Zn, Cr, Al) Spinel structures were successfully synthesized by solid reaction of oxides. At first a reference beige pigment CBD3002 from Qumisar company has been analysed by XRF, XRD, SEM and LPSA. Then according to these results, various formulations have been prepared and calcined at different conditions. The obtained pigments have been analysed by XRD, SEM/EDS, LPSA and CIE-Lab. The prepared pigments as well as the reference pigments, have been added to the glaze. Then, after glaze firing, their colors have been measured in CIE-Lab system. The results showed that color quality of the optimized pigment (i.e. ZnO/Cr2O3=4.16, Fe2O3 /Cr2O3=1.50 and Cal at 1200°C) prepared it in this work was better than the reference one. Adding more than 3Wt.% of the pigments in the glaze does not induce significant changes in color. The prepared pigment showed good thermal and chemical stability.
