Description
A dense, black powder that occurs in nature as the mineral pyrolusite. Manganese dioxide ore is the primary source for manganese metal. Synthetically produced manganese dioxide has a brownish tone. Both natural and synthetic manganese dioxide have been used for paint pigments and as a colorant in mortar. Manganese dioxide is used to make amethyst glass and to counteract the yellowish green color of iron oxide in glass. It is used as a black glaze and for painting on porcelain, faience, and majolica, and as a drier for oil paints.
