Pigments based on CeO 2 structure are known to give various pink-orange and red brown colour in ceramic glazes. This type of pigments is prepared by high temperature calcination of CeO 2 and Pr 6 O 11 with admixed rare-earth elements such as lanthanum oxide (La 2 O 3 ) and neodymium oxide (Nd 2 O 3 ). In this study, the use of enriched Eskişehir Kızılcaören region (Turkey) rare-earth oxides containing CeO 2 , La 2 O 3 and Nd 2 O 3 to synthesis CeO 2 -PrO 2 pigments was investigated. The resulting pigments were characterised using X-ray diffraction (XRD) and were used in double firing glazes. The colour obtained after glazing was defined as L*a*b* parameters by using UV-Vis Spectrophotometer and the results were compared to pigments obtained by using pure oxides.
