The synthesis f abve pigment was carried ut by mixing, and CaC as frmulated and then firing at 1000~100 C. T investigate the ptimum synthesis cnditin f the Uvarvite Garnet. it was prepared by using CaO t replace CaC, CaF and CaCl. T get green brighter clr, Al + was substituted fr Cr +. They were characterized by X-ray diffractin, UV-Vis spectrscpy, Raman spectrscpy and SEM analysis. When the pigments were applied t lime glazes (6 wt%), clr parameters f Uvarvite Garnet shwed the L* =0.99, a*=6. and b* =17.0.
