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.

HISTORICAL INFORMATION In an article dated 26 March 1963, the Warrnambool Standard reported: “A cannon which has lain on the ocean floor since the barque, Children, was wrecked at Childer’s Cove on January 15, 1839, was raised by three Warrnambool skindivers at the week-end…The cannon, weighing about 750 lb. and 4-ft. 6-in. in length…is in excellent order considering the length of time it has remained under-water”. No conservation measures were taken at that time, other than chipping off the marine growth with hammers and cold chisels. The minutes for the 4 February 1974 meeting of the Flagstaff Hill Planning Board recorded that “a cannon recovered some time ago was lying in the garden of [one of the three original divers] and that it could be picked up at any time”. Peter Ronald, past Manager and Diver for Flagstaff Hill, notes that the CHILDREN cannon would have been recovered by the other divers around 1964. When the cannon came into care of Flagstaff Hill it was given basic conservation relevant to the time. (At the same meeting the Board was advised of the recovery of an anchor from the wreck of the CHILDREN by Flagstaff Hill divers (Peter Ronald, Colin Goodall and Gary Hayden, and Hank Howey and Andrew Coffee), and its interim relocation in the sea at the end of the Warrnambool Breakwater while awaiting conservation). The CHILDREN was owned by the pioneering Henty family of Portland. She was en route from Launceston to Adelaide, when she foundered in rough conditions at Childers Cove on 14 January 1839. The CHILDREN was a small three-masted barque, only 29 metres long and 254 tons weight, with 14 crew members and 24 passengers (including 9 children) on board. The ship was also carrying an awkwardly ballasted cargo of 1500 sheep, 8 bullocks, 7 horses, 5000 London house bricks, 6 whaling boats, and general trade goods. When the CHILDREN was driven into the limestone stack at the entrance to the cove, the seas smashed her into pieces within half an hour, and 16 lives were lost. The CHILDREN was an all-wooden ship, built in 1825 at Liverpool, and her shipwreck in 1839 is one of colonial Victoria’s earliest and most significant maritime disasters. There is little left to mark the tragedy on the seabed now, apart from some of the house bricks intended for the Henty’s Portland Bay settlement. Despite its poor condition, the CHILDREN’s signal cannon remains an important and interpretable record of her demise, (along with her anchor, the bottom half of her ship’s bell, and portions of a brass porthole - artefacts that are also in the Flagstaff Hill collection). In 2015 the CHILDREN cannon will undergo further conservation. (Conservation Management Plan for Victorian Guns and Cannon, South Western Victoria, May 2008, ref W/F/06) The shipwreck of the CHILDREN is of state significance — Victorian Heritage Register No. S116.A 1.3 metre iron 6pdr cannon recovered from the wreck of the CHILDREN. The shape of the cannon tapers from a thick round breech to a flared muzzle, with an 8 centimetre bore, and two side trunnions for pivoting on a wooden gun carriage. It was recovered from the shipwreck site of the CHILDREN by local divers in 1963. This small muzzle-loading signal cannon is in poor and unrestored condition. The cannon’s upper profile of smooth grey metal casing has corroded off, leaving an extensively oxidised rough red surface of crumbling iron. The bottom half of the cannon remains intact although the outer smooth casing also appears to be separating from the iron core of the barrel. Original grey casting is also missing from the breech and muzzle ends of the cannon. Corrosion and spalling of the upper surface layer of the cannon has removed the maker’s marks and specificationsflagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, the children, ship’s cannon, signal cannon, childers cove, 1839 shipwreck, conservation of marine artefactsm, shipwreck-coast, flagstaff-hill-maritime-village, cannon, 6pdr small bore cannon, children cannon, defence, children, shipwreck, 1839

When the ship Schomberg was launched in 1855, she was considered the most perfect clipper ship ever to be built. James Blaine’s Black Ball Line had commissioned her to be built for their fleet of passenger liners. At a cost of £43,103, the Aberdeen builders designed her to sail faster than the quick clippers designed by North American Donald McKay. She was a three masted wooden clipper ship, built with diagonal planking of British oat with layers of Scottish larch. This luxury vessel was designed to transport emigrants to Melbourne in superior comfort. She had ventilation ducts to provide air to the lower decks and a dining saloon, smoking room, library and bathrooms for the first class passengers. At the launch of Schomberg’s maiden voyage, her master Captain ‘Bully’ Forbes, drunkenly predicted that he would make the journey between Liverpool and Melbourne in 60 days. Schomberg departed Liverpool on 6 October 1855 with 430 passengers and 3000 tons cargo including iron rails and equipment intended the build the Geelong Railway and a bridge over the Yarra from Melbourne to Hawthorn. The winds were poor as Schomberg sailed across the equator, slowing her journey considerably. She was 78 days out of Liverpool when she ran aground on a sand-spit near Peterborough, Victoria, on 27 December; the sand spit and the currents were not marked on Forbes’s map. Overnight, the crew launched a lifeboat to find a safe place to land the ship’s passengers. The scouting party returned to Schomberg and advised Forbes that it was best to wait until morning because the rough seas could easily overturn the small lifeboats. The ship’s Chief Officer spotted SS Queen at dawn and signalled the steamer. The master of the SS Queen approached the stranded vessel and all of Schomberg’s passengers were able to disembark safely. The Black Ball Line’s Melbourne agent sent a steamer to retrieve the passengers’ baggage from the Schomberg. Other steamers helped unload her cargo until the weather changed and prevented the salvage teams from accessing the ship. Local merchants Manifold & Bostock bought the wreck and cargo, but did not attempt to salvage the cargo still on board the ship. They eventually sold it on to a Melbourne businessman and two seafarers. After two of the men drowned when they tried to reach Schomberg, salvage efforts were abandoned.32 In 1975, divers from Flagstaff Hill, including Peter Ronald, found an ornate communion set at the wreck. The set comprised a jug, two chalices, a plate and a lid. The lid did not fit any of the other objects and in 1978 a piece of the lid broke off, revealing a glint of gold. As museum staff carefully examined the lid and removed marine growth, they found a diamond ring, which is currently on display in the Great Circle Gallery.33 Flagstaff Hill also holds ship fittings and equipment, personal effects, a lithograph, tickets and photograph from the Schomberg. Most of the artefacts were salvaged from the wreck by Peter Ronald, former director of Flagstaff Hill. The Schomberg, which is on the Victorian Heritage Register (VHR S612), has great historical significance as a rare example of a large, fast clipper ship on the England to Australia run, carrying emigrants at the time of the Victorian gold rush. She represents the technical advances made to break sailing records between Europe and Australia. Flagstaff Hill’s collection of artefacts from the Schomberg is significant for its association with the shipwreck. The collection is primarily significant because of the relationship between the objects, as together they have a high potential to interpret the story of the Schomberg. It is archaeologically significant as the remains of an international passenger Ship. It is historically significant for representing aspects of Victoria’s shipping history and for its association with the shipwreck and the ship, which was designed to be fastest and most luxurious of its day Metal Ring 2½" dia, Part eaten away due to corrosion.
