DOIAbstract
The color efficiency of ceramic glaze blue pigments obtained by synthesis methods was compared. the fired pigments and enam-eled samples were characterized by XRD, UV-vis-NIR spectroscopy, CIE-L*a*b * color-measurements, and SEM. The pigments obtained by the Pechini method presented a better solubility in the molten glazes than the pigments obtained by the mechanical mixture of the oxide precursors. The pigments obtained by the Pechini method also developed a bluer color hue than the pigment
