摘要

Inclusion pigments are disclosed based on zirconium silicate as a casing component and cobalt-free spinels as discrete, included colored compounds. The inclusion pigments are prepared by fusing a mixture of a zirconium dioxide source, a silicon dioxide source, one or more mineralizer and cobalt-free oxides in a ratio suitable for spinel- formation. The inclusion pigments have high enamel-fastness and high color-fastness. Further, the pigments are drain-resistant under usual decoration firing conditions.
