Description
Summary:The results of a study on the possibility of bulk dyeing ceramic bricks by incorporating manganese and iron ore and metallic slags and sludges from electroplating plants in the pastes are reported. Low-melting clays should first be bleached with chalk or fireclay or kaolin impregnated with solutions of transition metal salts in order to attain a broad colour range for the articles. Using natural raw materials and soluble salts of 3d elements significantly expanded the raw-material base, reduced the cost of the articles by replacing expensive materials, and combined synthesis of pigments and firing of the articles. 7 refs.
