FIELD: chemistry.
SUBSTANCE: invention relates to production of ceramic pigments for decorating porcelain-faience and majolica articles. The mixture for producing turquoise ceramic pigment of a mullite composition contains oxides SiO2, V2O5, Al2O3, K2O in form of a calcined spent vanadium catalyst (SVD) and additionally contains oxides Al2O3 and NiO in form of a nickel salt solution NiSO4·7H2O, with the following content of ingredients, wt %: spent vanadium catalyst SVD - 33.7-37.7; Al2O3 - 51.3-57.3; NiO - 5.0-15.0.
EFFECT: high heat resistance of the pigment.
