Notes
Used primarily in clay and glaze to achieve dark brown or black firied speckle. This is the same material as manganese dioxide powder, it is simply not ground as fine. Typically a 60-80 mesh material is used in amounts around 0.2-0.3%.
Pyrolusite ore is a source of manganese used widely in industry for the manufacture of manganese steel, alkaline batteries, decolorizing glass agents, and in ceramic bodies and glazes.
Pyrolusite can contain small amounts of quartz (e.g. 3%) as well as barium compounds (e.g. 2%) and trace amounts of lead (e.g. 0.2%). It is typically about 75% MnO2.
