This specimen was recovered from Broken Hill, NSW. It was given the name Mangan Hedenbergite in 1819 by Jöns Jakob Berzelius in honor of Mr. Anders Ludvig of Hedenberg who was the first to define hedenbergite as a mineral. Hedenbergite, belongs in the pyroxene group having a monoclinic crystal system. The mineral is extremely rarely found as a pure substance. Mangan Hedenbergite is a manganese bearing variety of Hedenbergite. Manganese is the world’s fourth most used mineral after iron, aluminium, and copper primarily because it has no satisfactory substitute in its major applications. Globally, the steel industry is the primary user of manganese metal, utilizing it as an alloy to enhance the strength and workability of steel and in the manufacture of tin cans. Manganese is a key component of certain widely used aluminium alloys and, in oxide form, dry cell batteries used in electric vehicles. These batteries are in high demand. Another potential use for manganese may as an additive to help coat and protect a car’s engine. Manganese is also used for non-metallurgical purposes such as plant fertilizers, animal feed, and colorants for bricks. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A hand-sized mineral specimen in shades of silver and blackmanganese, open cut mine, manganese ore processing, bell bay, tasmania, northern territory, steel industry, zinc-carbon batteries, alkaline batteries, tin cans

George Reed was a draftsman living in the City of Moorabbin c 1950 1899, David Misell, invented this "electric device" ( torch / flashlight) powered by "D" batteries laid front-to-back in a paper tube with the light bulb and a rough brass reflector at the end. Misell assigned his invention over to the American Electrical Novelty and Manufacturing Company owned by Conrad Hubert. In 1905, Hubert changed the name again to The American Ever Ready Company, selling torches / flashlights and batteries under the trademark Ever Ready. In 1906 the British Ever Ready Electrical Company was formed for export of batteries; it became independent in 1914. The American Ever Ready Company became part of National Carbon Company in 1914. The trademark was shortened to Eveready. In 1986, Union Carbide sold its Battery Products Division to Ralston Purina Company becoming the Eveready Battery Company, Inc. and in 1992, it bought the British Ever Ready Electrical Company. Prior to March 1, 1980, the company's alkaline battery had been called the Eveready Alkaline Battery (1959–1968), Eveready Alkaline Energizer (1968–1974) and Eveready Alkaline Power Cell (1974–February 29, 1980). On March 1, 1980, it was rebadged under its current name, Energizer. 2019 production plant in Portage, Wisconsin, but the majority of batteries are made in China and there are also numerous production facilities outside the US.
