It is no secret that copper is currently experiencing a huge upsurge in popularity. This is mainly thanks to its beautiful colour featuring heavily in the ranges of countless homeware retailers. There is, however, far more to this lustrous metal than just its appearance. For example, it has a greater level of thermal conductivity than any other metal (except silver); roughly 60% higher than aluminium and 3000% higher than stainless steel. This means copper is capable of heating up very quickly when compared to other metals. Perhaps a less commonly known property of copper is it being inherently antimicrobial. A wide range of harmful microbes are unable to survive for more than a couple of hours when in contact with a surface made of copper or one of its alloys (brass and bronze). This has led to it often being used for frequently touched surfaces such as door knobs, push plates and taps. A seemingly perfect material for cooking, it is therefore no surprise that it has been used in kitchens for millennia. But exactly when did we learn to utilise copper and its valuable assets? Origins It is hard to pin down an exact date when copper cookware was first introduced. Pieces discovered in regions of the middle east were dated as far back as 9000BC, suggesting cooking with copper began during the Neolithic period (≈10000-2000BC). As civilisations became increasingly capable in metallurgical techniques, metals such as copper became more widely used. It would have been around this time that copper replaced stone as the material used for making tools and cooking vessels. The use of copper is also well documented in Ancient Egypt. Not only was it used to produce water and oil containers, but it was also used to in medical practices. The antimicrobial nature of copper was exploited long before the concept of microorganisms was fully understood. The Smith Papyrus, a medical text written between 2600 and 2200BC records the use of copper in sterilising wounds and drinking water. Tin Lining Although copper is essential to many processes within the human body, it can become toxic if consumed in excess. It was this knowledge that gave rise to lining cookware with tin, a technique used for hundreds of years to prevent copper leaching in to food. These tin linings would eventually wear out and during the 18th and 19th century, it was common for people to send pans away to be re-tinned. This practice is becoming increasingly rare, as are the craftsmen who perform it. Despite this, there are still manufactures producing tin-lined copper cookware who also offer a re-lining service. Perhaps the best known of these is Mauviel, a French manufacturer who have been making this type of cookware since 1830. Tin has now largely been replaced by stainless steel as an interior cooking surface. Not only is it more cost effective, but the high grade of stainless steel used in premium cookware (typically 18/10) is highly resistant to corrosion and more durable than tin.Copper saucepans are still used in many kitchens.Small copper saucepan with long handle and three ridges around the circumference.

Geological specimen - Mangan Hedenbergite
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
