This research examines using Rice Husk Ash, $Cr_2O_3$ in producing the pink-red color. It studies the formation of cassiterite and malayaite crystallites, the primary factors in producing the pink-red color, in relation to the application of $Cr_2O_3$ to examine its coloring mechanism. In addition, the research intends to identify the optimum synthesizing temperature and maintaining time for crystallization of malayaite, a stable pink-red colorization factor in high temperature glaze during $Cr_2O_3$-$SnO_2$-CaO-$SiO_2$ family pigment synthesis. The optimum substituting contents is Rice Husk Ash : Quartz = 1 : 2, and the optimum temperature is suggested at $1300^{circ}C$ for 2 h based on analysis results by XRD, FT-IR, Raman microscope, SEM and UV-vis.
Key words: Malayaite, Sphene-pink, Rice husk ash, Pink-pigment
