Taken at the Ithacan Ball held at Earls Court, St. Kilda in 1948, the photograph is of members of the then Ladies Auxiliary. Pictured are from L-R: Loula Sikiotis-Kostos , Loulou Varvarigos, Ekaterini Sofianos (Pres.) Nancy Paxinos (Vice-president), Nina Varvarigos, Athanasia (Sia) Andrews, Effie Cominos-Raftopoulos. In 1991 Sia Andrews was the first woman to be elected president of the Ithacan Philanthropic Society. Although women were not permitted to become “Active Members” of the Ithacan Philanthropic Society until 1985, they played an important role in maintaining the social cohesion of the Ithacan community. Through organising social events such as the annual ball they also helped to connect the various generations of Ithacans to the Society.A black and white photograph of seven ladies dressed in evening attire and standing in front of a curtain.

Used by Colin Sach during his employment as Manager of the Chemistry Dept. at the University of Melbourne over a period of forty years.Manufacturing History Museum Victoria Commentary: Australian manufacturing history Philip Wollen Many years ago, when I was an ambition young man, I took over a company called Hecla.|This business was formed in 1872, long before Federation was even contemplated. The company established a rich tradition in the Australian manufacturing industry. The prodigious product range included kettles, mixers, toasters, hairdryers, urns, pie warmers, bain maries, and electric blankets for the domestic and commercial market. During the war it even manufactured parts for aircraft. It was one of Melbourne's largest employers.|Hecla was one of the pioneers in TV advertising, led by icons like Bert Newton, Bobby Limb, Evie Hayes and Graham Kennedy who ad Jibbed his way through irreverent and unscripted naughtiness about Hecla electric blankets and foot warmers. The slogan was 'By Hecla, its good1'. One can imagine the fun Bert and Graham had with their double entendres.|In the 60's Hecla entered into a partnership with General Electric and expanded rapidly. The massive factory, on the corner of Alexandra Parade and Chapel Street overlooking the Yarra River was a Melbourne landmark.|The business was formed by one of the scions of Melbourne industry. Mr Marriott was a metal worker of some repute, building the lights in front of Melbourne's Parliament House, the first steam car, the sideboard at the RACY Club, and the first factory to run on electricity.|By the time I acquired the company it was a shadow of its former self, incapable of competing with cheap Chinese imports. Wandering around the warehouse late one night I discovered a large, boarded up storeroom which appeared not to have been opened in decades.|Over several months I combed through the room, unearthing a treasure trove of products from a bygone era. Dusty files, engineering drawings, wooden prototypes, patent records, and correspondence from distributors on every continent.|I decided to track down an old man, Ray, long retired after 50 years with Hecla. He was not well off financially and welcomed the paid work. It turned out that he had done his apprenticeship with the company and there wasn't much he didn't know about it. He had been personally involved in the manufacture of almost every type of product on the Hecla smorgasbord's of products.|So for over 2 years he methodically assembled a mini museum of Hecla products, painstakingly polishing them and ensuring they were in working order. He attached the original brochure of each product and their respective warranty cards. For him it was ,a labour of love. For me it was a fascinating, if vicarious journey, into Australia's manufacturing past.|My colleagues complained that I was wasting money on his salary, our time and factory space on stuff that should have been dumped years ago. I tried to explain that I was merely a steward of the Hecla tradition, not merely an owner. Besides, the look on Ray's face convinced me that there was another dynamic at work. One I could see, but didn't really understand.|After he Passed away I faced a dilemma. What to do with this 'museum' of Hecla history. Nobody was interested.|So I kept the 'stuff' in private storage, hoping that same day someone would be interested in it. And the years passed.|Finally, I had a brainwave. Perhaps the Melbourne Museum would be interested. It was a long shot but I made the call. I had a nagging suspicion that they would think I was simply trying to get them to relieve me of paying for this huge collection to be taken to the tip.|To my surprise they said they would be willing to take a look, I secretly hoped that they would take the whole collection and not leave me with an incomplete jumble of appliances that I would indeed have to take to the tip.|On the appointed day, four serious looking young people showed up. Armed with digital cameras, note books and poker faces they spent four hours analysing the goods and the supporting materials. I asked them if they had any interest and their response was decidedly non-committal. It depends on the acquisitions committee, I was told. I was disheartened and packed up the exhibits to go back into storage.|Imagine my surprise when months later they telephoned to say that they had researched the history of the company, and yes, they would like to take the whole collection. And a truck with 'handlers' would arrive the following day to pick it up. Two years ago all Hecla's archives left me forever and went to the Museum's warehouse.|Well, to my delight I received a call yesterday inviting me to a private viewing of the exhibition at the Melbourne Museum. These young historians had meticulously assembled an impressive display of Melbourne's industry and technology going back to the 1800's. They thanked me like a significant benefactor when it is I who should have thanked them.|I saw the excitement in the eyes of these young people who had somehow managed to dig out and assemble memories from Australia's past. If this is the standard of care that the curators of the Melbourne Museum show all their exhibits, our history is in safe hands.|Their meticulous work took me back to those years long ago when I saw an old man lovingly assembling and cataloging a lifetime of his work.|It took me back to the day when Australians actually made things. Long before we became a nation of quarrymen. Before we became animal-factory 'farmers'. Of a time when products didn't break down, or dumped and replaced before the warranty expired. When men like Mr Marriott cared deeply about what their hands produced.|It reminded me of the call I received from an elderly lady in Tasmania asking for the electrical element for a Hecla K7 kettle. I searched the archives and called her back. The K7 was produced decades earlier and we no longer carried that spare part. She was quite disheartened and told me her kettle had finally 'given up the ghost' and she couldn't bear to part with it. It was a present from her husband on their wedding day 45 years ago. Her final words were 'they don't make them like that, do they? By Hecla they were good1'|I'm glad I followed my instinct and put Ray back on the payroll all those years ago..|I like to think Mr Marriott would have been pleased.Square metal box with electrical elements inside. Used to stand on or to put feet on when sitting. Elaborate pattern in centre with inscription.Hecla Foot Warmerdomestic items, heating

Higher education in east Gippsland dates back to 1890, and the opening of the Bairnsdale District School of Mines, In 1986 the Bairnsdale School of Mines and the Sale and Bairnsdale Technical schools amalgamated to form the East Gippsland Community College of TAFE. In 1995 it became the East Gippsland Institute of Technology, and in 2011 changed its name to Advance TAFE. The Bairnsdale District School of Mines Prospectus includes the members of council, a photographic image of the school, teaching staff, rules relating to students and instructors, Constitution, and a prospectus of subjects including Mining and Science Subjects, Diploma Courses, Preliminary Training, Metallurgy Course, Mining Engineering Course, Battery Manager's Certificate, Assayer's Certificate. It also includes a scale of fees, information on the Metallurgical Plant, Chemistry, Assaying and Metallurgy, Geology, Mining Geology, Mining, Petrology, Dynamics and Heat, Magnetism & Electricity, Mechanics Applied to Mining, Land Surveying, Mine Surveying, Algebra, Euclid, Trigonometry, Mechanical Drawing, Practical Plane Geometry, Practical Solid Geometry, Engineering Drawing, Art Subjects, and a list of certificates issued by the school since 1892.Grey soft covered book of 68 pages.

The Davey Paxman Experimental Steam Engine was purchased as the result of a bequest from Thomas Bath. The 'substantial sum' was used to build an Engineering Laboratory. The Ballarat School of Mines Council minutes of 08 November 1901 record: - Plans for [the] proposed building were submitted ... and ... it was resolved that a temporary building for an Engineering Laboratory be put up.' This laboratory, as an existing building, is first mentioned in the Ballarat School of Mines President's Annual Report of 1901, presented on 28 February 1902, reporting 'the erection of a building 67ft long by 33 ft wide' This report also lists all the equipment that would be accommodated in the Engineering Laboratory, including the experimental steam engine and boiler. The experimental Davey-Paxman steam engine arrived in Ballarat towards the end of 1902. The Engineering Laboratory was opened on 14 August 1903 by His Excellency Sir Sydenham Clarke. This engineering laboratory remained in use till about 1945. By 1944 preparations were under way at the Ballarat School of Mines to expand existing facilities, to be ready for the influx of returned soldiers. A new Heat Engines laboratory was built, this time of brick construction, replacing the previous corrugated-iron shed. In the early stages the steam engine was used to drive an overhead transmission shaft for machinery in the adjacent workshop. Later the steam engine was moved to a space that became the Heat Thermodynamics Laboratory. At the end of 1969 the engine was relocated to the Thermodynamics Laboratory at the then Ballarat Institute of Advanced Education (BIAE) Mt Helen Campus. It was donated to Sovereign Hill in 2006. According to the research of Rohan Lamb in 2001 around five experimental steam engines were made by Davey Paxman, and three of these had similar configuration to the Ballarat School of Mines Steam Engine, however, each of these was also unique with different valve arrangements. The list, which was on a scrap of paper in a folio held in the Essex Archives, confirmed that one was sent to India. The Ballarat steam engine can be dated to late 1901 to early 1902. Zig Plavina was responsible for moving the steam engine to Mount Helen, and worked on it as a technician for many years. He observed the following: * The condenser is driven by the low pressure engine. * The following arrangements are possible: i) the high pressure engine alone, exhausting to atmosphere. Condenser not used, crankshaft flanges not coupled. ii) crankshafts coupled, mains pressure (120 psi) steam supplied to high pressure engine, partially expanded steam delivered to low pressure engine (Tandem operation). Choice available re exhaust steam: either to the condenser or to atmosphere. iii) crankshafts not coupled, reduced pressure steam supplied to low pressure engine. Exhaust steam - either to the condenser or to atmosphere. * Valve arrangement - a choice of Pickering cut-off or throttle governor. On low pressure engine - throttle governor only.Black and white photograph of the Davey Paxman Experimental Steam Engine.

Made by Albert Henry Rogers who served in the British Army during WW1, the grandfather of the donor. It was made as a symbol of hope as receiving letters from home gave them hope. Hence the bullet made into a letter opener is a symbol of something made to kill into something to give hope. (Transcribed from the donor's description)Small letter opener consisting of a handle made from a .303 bullet and a blade made from an unknown metal. The projectile has been split in half lengthways and the blade soldered in. The markings on the cartridge indicate that it is a Mk VII cartridge manufactured by the Royal Laboratory in 1917.Both sides of the blade have decorative engraving on them. The left side has "ARRAS" engraved on it and the right side has "1918 YPRES" engraved on it. The base of the cartridge is marked R^L 17 and VII.ypres, arras, world war 1

A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top, usually with a rounded U-shaped bottom. Test tubes are widely used by pharmacists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays. Their round bottom and straight sides minimize mass loss when pouring, make them easier to clean, and allow convenient monitoring of the contents. The long, narrow neck slows down the spreading of vapours and gases to the environment. Test tubes are usually held in special-purpose racks, Test tubes for physics and chemistry are usually made of glass for better resistance to heat and corrosive chemicals and longer life. Tubes made from expansion-resistant glasses, such as borosilicate glass, can be placed directly over a Bunsen burner flame.8 clear glass test tubes of varied capacity with 3 glass mixers sitting in a wooden stand.
