Inorganic pigments produced and marketed as fine powders are a base for many decorative and protective coatings and are used for mass colouration of many materials including glazes and ceramic bodies [1]. Ceramic pigments are basically white or coloured substances with high thermal stability and chemical resistance enabling their further processing at high temperatures [2]. Recently, the development of new ceramic materials has encouraged the research and application of pigments stable at over 1200 C [3,4].
