However, these pigments are sensitive to reducing conditions, and are incompatible with chromium-containing pigments. Praseodymium zircon pigments3 have excellent tinting strength in most glazes. They can be used in most glazes,
and are compatible with other pigments. Finally, in the V–ZrO2 pigment, monoclinic zirconia gives a weaker
yellow than tin vanadium and substantially muddier than praseodymium zircon yellows.4
