This crucible was raised from the wreck of the LOCH ARD. It is one of six similar relics, in a range of sizes, now in the Flagstaff Hill collection. All bear markings to indicate their manufacture by the Morgan brothers of Battersea, trading as the Patent Plumbago Crucible Co. A crucible is a container used for purifying and melting metals so that they can be cast in a mould to a predetermined shape and use. They must withstand extremely high temperatures, and abrupt cooling, and shed their contents with minimal adherence. The addition of graphite to the traditional firing clays greatly enhanced the durability of industrial crucibles in mid-Victorian Britain, a significant technological advance at a time of great activity in foundries and expansion of demand for refined metals. The Morgans first noticed the advantages of graphite crucibles at the Great Exhibition held in London in 1851. Initially, they contracted to be sole selling agents for the American-made products of Joseph Dixon and Co. from New Jersey, but in 1856 they obtained that firm’s manufacturing rights and began producing their own graphite crucibles from the South London site. The Morgans imported crystalline graphite in 4-5 cwt casks from the British colony of Ceylon (now Sri Lanka) and mixed it with conventional English (Stourbridge) clays to be fired in kilns. Their products were purchased by the Royal Mints in London and India, and exported to official mints in France and Germany. They were successful exhibitors of their crucibles and furnaces at the London Exhibition held in 1861 (Class 1, Mining, quarrying, metallurgy and mineral products, Exhibit 265, Patent Plumbago Crucible Co). The range of sizes represented by the six crucibles retrieved from the LOCH ARD, suggests they may have been part of a sample shipment intended for similar promotion in the Australian colonies ― at Melbourne’s International Exhibition to be held in 1880. The summary of the LOCH ARD cargo manifest, by Don Charlwood in ‘Wrecks and Reputations’, does not mention any crucibles, implying that they were not a large consignment of uniform items. A newspaper account of an 1864 tour of the Morgan brothers’ ‘Black Potteries’ at Battersea indicates: “All the pots were numbered according to their contents, each number standing for one kilogram, or a little over two pounds; a No. 2 crucible contains two kilogrammes; a No. 3, three kilogrammes, and so on.” These numbers are obscured by marine sediment on three of the crucibles in the Flagstaff Hill collection, but those legible on the remaining three are 5, 6, and 8. None of the six is of the same size from a visual appraisal. A brief history of the Loch Ard (1873-1878): - The sailing ship Loch Ard was one of the famous Loch Line of ships that sailed the long voyage from England to Australia. Barclay, Curdle and Co. built the three-masted iron vessel in Glasgow in 1873. It had sailed three trips to Australia and one trip to Calcutta before its fateful voyage. Loch Ard left England on March 2, 1878, under the command of recently married, 29-year-old Captain Gibbs. It was bound for Melbourne with a crew of 37, plus 17 passengers. The general cargo reflected the affluence of Melbourne at the time. Onboard were straw hats, umbrellas, perfumes, clay pipes, pianos, clocks, confectionery, linen and candles, and a heavier load of railway irons, cement, lead and copper. Other cargo included items intended for display in the Melbourne International Exhibition of 1880. The Loch Ard had been sailing for three months and was close to its destination on June 1, 1878. Captain Gibbs had expected to see land at about 3 am but the Loch Ard ran into a fog that greatly reduced visibility and there was no sign of land or the Cape Otway lighthouse. The fog lifted at 4 am and the sheer cliffs of Victoria's west coast were much closer to them than Captain Gibbs expected. He tried to manage the vessel but failed and the ship struck a reef at the base of Mutton Bird Island, near Port Campbell. The top deck loosened from the hull, and the masts and rigging crashed down, knocking passengers and crew overboard. The lifeboat was launched by Tom Pearce but crashed into the side of Loch Ard and capsized. He clung onto its overturned hull and sheltered under it. He drifted out to sea and the tide brought him back to what is now called Loch Ard Gorge. He swam to shore and found a cave for shelter. A passenger, Eva Carmichael, had raced onto the deck to find out what was happening and was confronted by towering cliffs above the ship. She was soon swept off the ship by a huge wave. Eva saw Tom Pearce on a small rocky beach and yelled to attract his attention. He swam out and dragged her to the shelter of the cave. He revived her with a bottle of brandy from a case that had washed up on the beach. Tom scaled a cliff in search of help and followed some horse hoof prints. He came from two men from Glenample Station, three and a half miles away. He told the men of the tragedy and then returned to the gorge while the two men rode back to the station to get help. They reached Loch Ard Gorge and took the two shipwreck survivors to Glenample Station to recover. Eva stayed at the station for six weeks before returning to Ireland by steamship. In Melbourne, Tom Pearce received a hero's welcome and was presented with a medal and some money. Of the 54 crew members and passengers on board, only two survived: the apprentice, Tom Pearce and the young woman passenger, Eva Carmichael, who lost her family in the tragedy. The shipwreck of the LOCH ARD is of State significance ― Victorian Heritage Register S417. Flagstaff Hill’s collection of artefacts from LOCH ARD is significant for being one of the largest collections of artefacts from this shipwreck in Victoria. It is significant for its association with the shipwreck, which is on the Victorian Heritage Register (VHR S417). The collection is significant because of the relationship between the objects, as together they have a high potential to interpret the story of the LOCH ARD. The LOCH ARD collection is archaeologically significant as the remains of a large international passenger and cargo ship. The LOCH ARD collection is historically significant for representing aspects of Victoria’s shipping history and its potential to interpret sub-theme 1.5 of Victoria’s Framework of Historical Themes (living with natural processes). The collection is also historically significant for its association with the LOCH ARD, which was one of the worst and best-known shipwrecks in Victoria’s history.A Morgan’s Patent graphite crucible No.8 (i.e. 8kgs capacity), one of a set.

Crucibles are used for heating and pouring molten metal. The set of six crucibles was raised from the wreck of the Loch Ard and includes a range of sizes, now in the Flagstaff Hill collection. All were manufactured by the Morgan brothers who founded the Patent Plumbago Crucible Company in 1856, making crucibles in a small factory in Battersea London. A crucible is a container used for purifying and melting metals so that they can be cast in a mould to a predetermined shape and use. They must withstand extremely high temperatures, and abrupt cooling, and shed their contents with minimal adherence. The addition of graphite to the traditional firing clays greatly enhanced the durability of industrial crucibles this technique was pioneered by the Morgan Bros thereby making a significant technological advance in foundry technology and metallurgy.

The shipwreck of the Loch Ard is of significance for Victoria and is registered on the Victorian Heritage Register ( S 417). Flagstaff Hill has a varied collection of artefacts from Loch Ard and its collection is significant for being one of the largest accumulation of artefacts from this notable Victorian shipwreck of which the subject items are a small part. The collection's objects give us a snapshot of how we can interpret the story of this tragic event. The collection is also archaeologically significant as it represents aspects of Victoria's shipping history that allows us to interpret Victoria's social and historical themes of the time. Through is associated with the worst and best-known shipwreck in Victoria's history.This crucible is the smallest of three nested crucibles, or fluxing pots, numbered according to their size. These containers rise slightly from a smaller flat base to a wider open top with a lip for pouring. They were recovered from the wreck of the Loch Ard. The crucibles have a coating of sediment that obscures some of their numerical specifications of size and capacity. Made by the Patent Plumbago Crucible Company at the Battersea Works in London.

Negretti and Zambra 1850-1980s were optical instrument makers and mathematical instrument makers based in London, England. The firm of Negretti and Zambra was established in 1850 by Henry Negretti and Joseph Zambra who had formed a partnership. Their skill was immediately apparent when exhibiting at the 1851 Great Exhibition at Hyde Park, they were the only English instrument makers to receive a prize medal for meteorological instruments, resulting in their appointment as instrument makers to the queen, Greenwich observatory, and the British Meteorological Society. In 1853, when the Crystal Palace was re-erected in Sydenham, Negretti and Zambra became the official photographers of the Crystal Palace Company, which allowed them to photograph the interior and grounds of the new building. The firm made use of this access to produce a number of stereographs. Between 1855 and 1857 Negretti and Zambra commissioned photographer Pierre Rossier to travel to China to document the Second Opium War. Although Rossier subsequently was unable to accompany to Anglo-French forces in that campaign, he nevertheless produced a number of stereographs and other photographs of China, Japan, the Philippines and Siam (now Thailand), which Negretti and Zambra published and that represented the first commercial photographs of those countries. In 1856 Negretti and Zambra sponsored a photographic expedition to Egypt, Nubia and Ethiopia conducted by Francis Firth. In 1864 Negretti and Zambra (themselves) photographed Shakespeare's House at Stratford on Avon. A sepia photograph was then pasted onto card 4" × 2.5". This was then presented to visitors to the Crystal Palace to enable them to compare it with the model erected by Mr E. T. Parr in the Centre Transept. The card itself is headed "Crystal Palace April 23rd 1864." That year they also published a book, titled A Treatise on Meteorological Instruments, (which was reprinted in 1995). Throughout World War One Negretti and Zambra were entirely engaged in the production of various instruments for the Ministry of Munitions. They developed many instruments for the Air Ministry including a mercury-in-steel distance thermometer for taking the oil and air temperatures in aircraft which was patented in 1920. In 1946 the company went private and in 1948 the company was made public, and by 1950 Negretti and Zambra had 821 employees in Britain. In order to increase production and to safeguard future development in 1964, they purchased a modern factory at Aylesbury for all their production. In 1981 Negretti and Zambra were taken over by a group of financial institutions in the form of Western Scientific Instruments and in 1985 the company was acquired by Meggitt Holdings.The subject compass is just one type of the many marine and scientific, optical items this company produced over it’s life time. Negretti and Zambra were prolific manufactures of types of items as well as being very prominent in photography pioneering new innervation's and sponsoring expeditions to little known countries to document peoples daily lives and culture through photography.Azimuth compass on tripod in a fitted wooden box with a round spirit level included, lid of box has three indented circles where the legs of the compass fit when it is set up for use.

Beam balance (gold scales) made by Oertling - London. The balance is in a case made of mahogany and fully glassed, it has two draws. The brass scales are built into the case. The maker's name is present on the base of the scale. There is a brass knob that fits in the front to make adjustment to the scales and also on either side of the exterior case to set the top of the scales. There are two front draw, the left one is missing the drawer knob.mining, equipment, scale, ludwig oertling (1818-1893) was born near hamburg and gained his apprenticeship in instrument-making with his brother johann. he immigrated to london in 1840, where he joined instrument-maker and assayer george makins (1815-1893). oertling collaborated with makins and built his first balance, which was "a twin-column assay type with a light lattice beam". by 1851, the year of the great international exhibition of the works of all nations, oertling had established his own instrument-making business, employed five instrument-makers, and by 1861, ten staff were engaged in designing and making instruments, principally analytical balances. oertling's first twin-column beam balance was the prototype for all oertling assay balances that were produced during the next century and exported to the british colonies: australia, new zealand, canada, south africa and india, to europe and america.

In 1791 Prague organized the first World's Fair, Bohemia (modern-day Czech Republic). The first industrial exhibition was on the occasion of the coronation of Leopold II as a king of Bohemia, which took place in Clementinum, and celebrated the considerable sophistication of manufacturing methods in the Czech lands during that time period. The French tradition of national exhibitions culminated with the French Industrial Exposition of 1844 held in Paris. This fair was followed by other national exhibitions in Europe. In 1851, under the title "Great Exhibition of the Works of Industry of All Nations", the World Expo was held in The Crystal Palace in Hyde Park, London, the United Kingdom. The Great Exhibition, as it is often called, was an idea of Prince Albert, Queen Victoria's husband, and is usually considered to be the first international exhibition of manufactured products. It influenced the development of several aspects of society, including art-and-design education, international trade and relations, and tourism. This expo was the precedent for the many international exhibitions, later called World Expos, that have continued to be held to the present time. (source; Wikipedia) Commemorative medal.
