In this research,a brown spinel based pigment has been synthesized. At first a reference brown pigment has been analysed by XRF, XRD and SEM. Then according to these results, various formulations have been prepared and calcined at defferent conditions. The obtained pigments have been analysed by CIE-Lab, XRF, XRD, SEM and LPSA. The prepared pigments as well as the reference pigment, have been added to the glaze. Then, after glost firring, their colors have been measured in CIE-Lab system. The results showed that color quality of the optimized pigment (i.e. ZnO/Cr2O3=1.6, Fe2O3/ Cr2O3=0.87 and Cal at 1250˚C) prepared it in this work was comparable with the reference one.The prepared pigment showed good thermal and chemical stability.
