Stirrer, used in Optical Glass work, Hartung & associates, 1941 Ernst Johannes Hartung was a chemist and astronomer. Educated at the University of Melbourne (BSc 1913, DSc 1919), he became lecturer in 1919, associate professor in 1924, and succeeded Rivett as chair of chemistry in 1928, remaining in this position until 1953. Hartung?s lecturing style surged with enthusiasm and he employed the use of screen projections to demonstrate chemical phenomena to large undergraduate classes. In 1935 he recorded Brownian movement in colloidal solutions on 35 mm cinefilm, which was later copied onto 16 mm film for the Eastman Kodak Co. World Science Library. This can be viewed in the Chemistry laboratory. He researched the photo decomposition of silver halides, and was awarded the David Syme Prize in 1926. He devoted time to the design and construction of a large, new chemistry building for the School of Chemistry (built 1938?1939). During World War II he was approached by Professor Thomas Laby, chairman of the Optical Munitions Panel, to chair the advisory committee on optical materials, to produce high quality optical glass in Australia. This was successful, with large-scale production achieved within ten months at a reasonable cost. Hartung served three terms as general President of the (Royal) Australian Chemical Institute, was an ex-officio councillor of the Council for Scientific and Industrial Research, and a Trustee of the Museum of Applied Science (now part of Museum Victoria).

An original Kerr-Grant Microbalance, modified by E.J.Hartung This balance was invented in the chemistry department by Bertram Dillon Steele, later first Professor of Chemistry at the University of Queensland 1910-1930, in collaboration with Professor Kerr Grant, Physics. The design was widely used by other chemists, including Masson's mentor, Professor Ramsay, working in London on newly discovered rare gases (especially Radon), and Professor Hartung in Melbourne, investigating the chemistry of the decomposition of silver salts in photographic processes. The principle of the microbalance was to measure the change in density of a gas by the shift in the balancing beam due to a change in pressure of the gas in the balance case. The quartz balancing beam was made by Bertram Steele who was particularly skilled in glassblowing. A quartz beam is the beam of the Aston microbalance based on the Steele/Grant instrument, and described by F.W. Aston, the inventor of the mass spectrometer. The bulb at one end of the beam contained a fixed amount of air, so that a change in the pressure of gas in the balance case changed the buoyancy of the beam, yielding a displacement in the beam which could be measured. By this means, differences in weight of about 10 nanogram could be measured, in amounts of up to 0.1 gram. Such differences are significant the increase in weight of a metal sample due to surface oxidation (Steele's interest) in the weight loss due to radioactive decay of Radium (Ramsay's work), and in the estimates of density change due to the isotopic distribution of Neon (Aston).

In August 1884, Alfred Hirst who had started his trade as a watch repairer and was described as a watchmaker extraordinaire established Hirst Brothers and Company, on Union Street in Oldham Manchester. He took his two stepbrothers into the business and the company was set up to produce timepieces and jewellery as well as importing “Limit company” Swiss watches and precision machine tools for the watch and clock trade. By 1902 Hirst Brothers. had become a limited company and was still growing, adding other businesses in Manchester in 1904 and at Birmingham in 1907. The quality of the clocks and watches was such that Alfred Hirst realised his greatest ambition in 1912 with a range of watches which carried the "Limit" trademark. These watch movements had originally been made in Switzerland and shipped to Hirst Bros. to be put into British made “Dennison” cases. This trade brought even more growth with additional sales offices opening in London and Glasgow. At the outbreak of the First World War in 1914 found them manufacturing aircraft parts including revolution counters and optical instruments. The firm had been tasked by the Ministry of Munitions to solve the problem of pilots dropping bombs by hand and as a result, they effectively created the first bomb rack. After the war, the company once again began to prosper and with the demand for their products increasing they looked to build a new purpose-built factory to manufacture their products. In 1917 they purchased a seven-acre field site at Tame Side Dobcross, the designing of the new factory was passed onto local architect AJ Howcroft. His brief for the design of the clockworks would have been prompted by Alfred Hirst who having visited modern factories in the United States was inspired by the latest factory designs providing as much daylight as possible during working hours. The factory was eventually completed in 1920, by the mid-1920s there were cheap clock imports from Germany and production turned to radio sets and other components as well as counter and gas meters for the "Parkinson and Cowan" company who was later to take over the business. In 1926 came the cotton crash and the District Bank who had loans with the company foreclosed on the Hirst loan. The company did survive and throughout the second World, War II were involved in munitions work at the factory as well as making instruments for various aircraft. In the 1950’s they were producing meters and high grade measuring equipment but by the 1970's the business had closed and the factory was demolished in the mid-1980 "s The item is a good example of the later use of an early mechanism “Fusee” that was originally invented around 1525 in Prague. This type of clock mechanism was replaced as watchmakers looked for mechanisms that could reduce the size of clocks and watches, it appears England was the only country to continue making clocks with a Fusee device until around 1900,s of which our clock is an example. The use of a Fusee movement eventually became obsolete in 1970,s. The item is significant for the collection as it is a clock with a movement that has long since been made obsolete. Fusee type gallery wall clock made by Tame Side with an 8-day mechanical fusee movement. The white enamel dial is a little crazed and some of the Roman Numeral numbers are fading due to over-cleaning. The movement has a hexagonal iron pendulum bob hooking onto a pendulum rod with a spring-wound anchor escapement.Only mark is stamped on the movement believed to be a production number "13490" and made in Tame Side.
