for more information.
Manganese dioxide is the inorganic compound with the formula MnO2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery. MnO2 is also used as a pigment and as a precursor to other manganese compounds.
Uses in Pottery
The applications include the use of MnO2 as an inorganic pigment in ceramics and in glassmaking. Manganese is a colorant using in bodies and glazes, producing blacks, browns, and purples.
Smaller amounts are easily dissolved in most glaze melts, however, around the 5% threshold, the manganese will precipitate and crystallize. In large amounts in a glaze (i.e. 20%), metallic surfaces are likely.
In glazes below 1080°C, it can give coffee color browns when used with tin.
