Description
Summary:The results of a study of the possibility of bulk dyeing of ceramic brick by incorporating manganese and iron ore and metallic slags and sludges from electroplating plants in the pastes are reported. It was found that 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 color scale for the articles. Using natural raw materials and soluble salts of 3d elements significantly expands the raw-materials base, reduces the cost of the ceramic articles by replacing expensive materials, and combines synthesis of pigments and firing of the articles.
