It studies the frmatin f cassiterite and malayaite crystallites, the primary factrs in prducing the pink-red clr, in relatin t the applicatin f Cr 2 t examine its clring mechanism. In additin, the research intends t identify the ptimum synthesizing temperature and maintaining time fr crystallizatin f malayaite, a stable pink-red clrizatin factr in high temperature glaze during Cr 2 family pigment synthesis. The ptimum substituting cntents is Rice Husk Ash : Quartz = 1 : 2, and the ptimum temperature is suggested at 1300 C fr 2 h based n analysis results by XRD, FT-IR, Raman micrscpe, SEM and UV-vis.
