Black ceramic pigments based on open-hearth slag are obtained. The possibility and sequence of physicalchemical processes occurring during kilning of pigment mixes are evaluated and the nature of the color-carrying phases in the products of their heat-treatment is determined. The relation between the crystal-phase composition and the optical indicators of the slag-containing pigments is studied. It is shown that such pigments are promising for coloring various glazes.

Notes
An equal molar ratio of magnesium, iron, and cobalt oxides in the composition of the corresponding solid solutions was used in the calculations.
