Gasometers resulted from complex engineering design evolving from primitive gasholders first used in 1824 in England to power street lights. The 20th century gasometer, (as used at the Highett Gasworks), was comprised of a series of large interconnected, telescopic, cylindrical vessels or lifts, which rose and fell depending on the volume of gas stored. The gasholder operated on a basic principle of a gas-filled floating vessel, rising and falling in a seal of water. The Highett Gasworks had its beginning in 1939 but its beginnings commenced sixty-two years earlier when the privately owned Brighton Gas Company was floated in 1877. By 1880 the company was performing well and making excellent profits. The company was welcomed by residents wanting to replace the shadowy light of a kerosene lamp with the bright luminescence of "modern" gas lamps. The land developers of the day were also keen supporters. But by 1884 people became disgrunted because either the gas had not reached them yet or because the quality of the supply had diminished due to the increasing use. In 1885 a second private gas company, the Central Brighton and Moorabbin Gas Co, Chaired by "Tommy" Bent was floated and for many years the two gas companies enjoyed a shared monopoly in supplying gas from their New Street Works. In the 1930s the company expanded its gas production facilities to Highett where it had purchased 45 acres of land adjacent to the Melbourne-Frankston railway line. A gasholder with a capacity of 750,000 cubic feet was erected on the Highett land in 1927 and connected with high pressure mains to the Brighton works. Three years later the company directors decided to proceed with the construction of a vertical retort house and coal store. Following a "lull" during the Great Depression work recommenced in 1936 and by 1939 the first complete gas-making plant was completed, and gas making commenced. Over the next twenty one years other significant extensions occurred, including an amenities block to accomodate 100 workers. In 1969 Esso commenced the introduction of natural gas to residents homes and the gradual decommissioning of the Highett Gasworks commenced. Part of the old Highett Gasworks site is now a council owned parkThe photos of the Higett Gasworks, now demolished, recall their long history, that originated in the 1800s with the production of gas to supply homes with a new, much improved light source, and later it's other applications such as for stoves etc. The arrival of gas in the Shire of Moorabbin was a huge step forward that encouraged further building and development in the area.Three Photographs of the Highett Gasworks.

The Highett Gas Works were a landmark along the Nepean Highway for many years. With the cessation of the gasification of coal and the introduction of natural gas to Victoria, the gas holders were demolished and the Sir William Fry Reserve was developed on the southern end of the site. The Gas and Fuel redeveloped the northern end of the site with modern offices and laboratories for the organisation's scientific services. At this time, the chimney and retort house were retained.The Highett Gasworks had its beginning in 1939 operated by the Central Brighton and Moorabbin Gas Co Ltd. The company had expanded its gas production facilities to Highett where it had purchased 45 acres of land adjacent to the Melbourne-Frankston railway line. The first gasholder was erected on the Highett site in 1927 and connected with high pressure mains to the Brighton Gas Works. In 1939 the building program including gasometers, the vertical retort house and coal store was completed and gas making commenced. Its area of supply covered approximately 70 square miles and included the municipalities of Brighton, Sandringham, Moorabbin, Mordialloc, Chelsea and part of Dandenong. The Gas and Fuel Corporation eventually took over operations and with the disaggregation and privatisation of the organisation, the site was eventually closed c. 2002.Black and white aerial photograph featuring the Highett Gas Works with gasholders and retort house.

The Bendigo Gas Works are one of around three remaining intact 19th century gas works in the world, and the only one in Australia. It is on the Victorian Heritage Register and regarded by Institution of Engineers Australia as an internationally significant example of an entire provincial gasworks The Bendigo Gasworks operated from 1860 until 1973 when natural gas was introduced and remain as they were at the time of closure; a treasure of industrial heritage frozen in time. It is an internationally significant example of an entire provincial gasworks. It has the only horizontal gas-producing retorts in Australia. Coal Gas was manufactured here from 1860 and operated continuously until the introduction of natural gas in 1973. The works were operated by the Bendigo Gas Company until purchased by the Gas and Fuel Corporation in 1958 at which time they were supplying 3,500 consumers. During the Second World War the works were expanded by the Ministry of Munitions to serve the Bendigo Ordinance Factory. The original works were constructed during 1859-1860 under the direction of engineer Alexander Kennedy Smith (1824 - 1881) and developed in a period of growth by W. A. Simco, General Manager 1922-1939.

Gold bearing ore is pulverized by cast iron stampers (steam driven) and material then passes over a large copper plate covered in mercury causing the gold particles to combine with the mercury to form an amalgam which is scraped of and placed in a retort. The retort is heated causing the mercury to evaporate leaving the gold to be refined into ingots. The mercury is cooled as it leaves the retort and is reused. A second tray covered in what is called a blanket traps any fine gold that has passed the first plate. Finally the residue material goes over a vibrating table called a Wilfley Table which captures any iron pyrites which may contain about three percent gold. this is roasted and treated to recover any remaining gold at a special treatment plant.Wooden model of a five heads gold stamper battery.

On 29 February 1892 'The Argus' reported on the first Annual Meeting of the Clunes School of Mines. "The annual meeting of the council of the Clunes School of Mines was held last evening at the town-hall. In place of members of the council retiring by effluxion of time the following were elected: — Rev. Elder Gray, Messrs. John Beveridge, R. Nichol, J. Bryant, W. T. Pitcher, J. H. Daley, and T. Gilbert. The first annual report, showing remarkable progress, was received and adopted. The following officers were elected for the ensuing year: — Rev. E. Grey, president; Rev. Father John Barrett and Dr. Gordon, vice- presidents; Mr. Joseph Bryant, hon. director; Mr. W. Y. Witherden, hon. treasurer, Mr. H. E. Sando retained the office of secretary, and the officers for the time being were appointed trustees." Great satisfaction was expressed with the success of the school, and the progress and extent of the classes. It was referred to a sub committee to make arrangements for allowing the free inclusion, in certain classes, of a limited number of boys and girls of 14 and upward, who on examination qualified themselves for the privilege. An offer by an anonymous resident to pay the fees for four miners for admission to any class in the school was announced by the president, and received with thanks.Two photographs showing the exterior of a weatherboard building known as the former Ballarat School of Mines Clunes campus.

Ore bearing rock brought out of the mine was crushed at the battery by heavy metal stampers and the fine material passed over copper pates coated with mercury. Gold particles would combine with the mercury forming an amalgam which was then scrapped off the copper plates and put into the amalgam bucket ready for retorting too extract the gold. The amalgam of mercury and gold was placed into the retort which was heated to evaporate the mercury. The mercury cooled as it ran down the pipe which was recovered to be reused leaving the gold behind. The gold would later be put into a crucible and heated to burn of impurities and the molten pure gold poured into an ingot.A heavy cast iron bucket 20 centimetres high, 16 centimetres in diameter at its base and 22 centimetres diameter at the top.

The Archbold (Chewton) Gold Treatment Works was erected c.1884 by Jeremiah Archbold who operated an assay and metallurgical business specialising in the treatment of gold-bearing ore. The battery, furnaces and Chilean mills which survive on the site suggest that the chlorination process was used to assay pyritic ore. The works subsequently incorporated the cyanide process after its introduction to Victoria in the late 1890s. Upon Jeremiah's death in 1917, the works continued to be run by one of his sons, Herbert. Herbert Archbold went on to become widely known throughout Victoria for his cyaniding expertise. Herbert died in 1966 and the property was bought by his son Harry. When Harry Archbold died in the late 1980s the treatment works was closed and everything left as it was. https://vhd.heritagecouncil.vic.gov.au/places/7899/download-reportNineteen page document.

This plan was commissioned by the Department of Administrative Services to outline the heritage qualities of Fortuna and provide guidelines for its future conservation. The property was owned by the Commonwealth of Australia, managed by the Department of Defence, and occupied by the Army Survey Corps. The study primarily addresses key structures on the site, including the former house, laundry, quartz mill, coach house, stables, swimming bath, summerhouse, fountain, and arbor. Fortuna is listed on the Register of the National Estate, classified by the National Trust of Australia (Victoria), and designated as a significant building in the City of Bendigo Planning Scheme. The site was originally part of the Ravenswood or Mount Alexander squatting run, licensed in 1840. Gold was discovered in the area in 1851, leading to the establishment of government camps and the development of Bendigo as a major gold mining center. The Victoria reef, located near the site, was one of the principal gold-bearing reefs in Bendigo, with mining activity beginning in the mid-1850s. The evolution of mining technology and the formation of mining companies played a significant role in the area's development. Fortuna is recognized for its historical, architectural, and environmental value, with conservation efforts focused on the estate as it existed around 1907 under the Lansells' ownership. Key structures to be conserved include the main house, shadehouse, stables, coach house, swimming bath, battery, retort room, Pompeii fountain, summerhouse, arbour, garage, laundry, and tunnel The plan includes detailed documentation of the site's existing structures, site plans, building plans, elevations, and features. Early photographs, drawings, and chronological development plans are used to support the analysis. The document assesses the historical, architectural, and environmental significance of the site.It provides a statement of cultural significance and recommendations for conservation priorities.

"The United Pyrites Company's Works are situated about three quarters of a mile from Spargo Brothers, and are on the northern side of the Marong road, in Pinch-gut Gully. Two processes are followed at these works, viz., the amalgamating process and the treatment by means of chlorine gas. The latter is called the Newbery-Vautin system, and the mode pursued is that laid down by Mr. Cosmo Newbery and Mr Vautin, whose names have been given to the process. Mr. Edwards manages these works. Three reverbatory furnaces are used to roast the pyrites, which is weighed in the truck before being put into the furnaces. At this weighbridge a sample of each lot is kept, and if the yield is not equal to expectation, the works are carefully gone over to see where the fault occurs. Care is taken at the furnace to regulate the heat, otherwise the pyrites might slag instead of roasting evenly right through. An immense revolving furnace (made of boiler iron) was used at these works. It was found to be suitable for treating blanket sand, but was not a success for roasting coarse pyrites. The process of amalgamating by means of Chilian mills is the same in these works as at the Western Works, but the United Works are on a larger scale, and eleven mills are utilised. It is the chlorine gas process which is most interesting here. The gas is made from sulphuric acid, black oxide of manganese, and common salt, and the gas is introduced into huge vats, where it works its way through a filter of pieces of quartz and then through the bed of roasted pyrites lying above. The action of the gas transforms the gold into chloride of gold. This is easily dissolved in water, and in that form is drawn off into huge delf jars, where the use of sulphate of iron precipitates the gold to the bottom. A small battery—eight head of stamps in two boxes—is in use here to crush small consignments of stone sent for trial. Test crushings come from all the Australasian colonies, and even from India. The jars used are manufactured at Epsom, and some of the salt used is also of home manufacture, from the Salt Lakes on the Northern plains. Mr. Edwards took us over a new building in course of erection, and in which the chlorine gas is to be generated in the midst of the pyrites— a still further advancement in the new process. There is some very good machinery in this new building, and the tailings from the ordinary pyrites works will also be treated by this chlorine gas system, which has been found to work well at Mount Morgan, in Queensland. The purest of gold is obtained by this process, the gold passing in solution into a charcoal filter, from which it emerges in the shape of metallic gold. We saw some nice cakes of retorted gold at the works. One of 26oz. was from some New Zealand pyrites (2½ tons), and assayed over 23 carats. There were also cakes of Avoca gold, of silver, and of the tremulous amalgam."

Cast iron mercury bucket, used to hold mercury, potentially in the process of recovering minute pieces of gold mixed in soil and sediments. See research page for description of one process of using mercury to extract gold.gold mines, mining equipment, mercury bucket, miners used mercury in a number of ways to amalgamate gold, with each mill or battery operator having their preferred method depending on the nature of the ore. by the late 1850s the most common way of crushing goldbearing quartz ores or consolidated alluvial cements was in a stamp battery. the battery featured heavy iron stamp heads held in a frame, with each head often weighing up to 500 pounds (226 kg) or more (see msv 1880, page 45) (birrell 2005). stamp heads were lifted and dropped by a rotating overhead cam shaft driven by a steam engine or water wheel. ore was fed into a large cast-iron battery box, mixed with a steady stream of water, and pulverised by the stamp heads. in some batteries, mercury was placed in the base of the boxes to amalgamate with freed gold. the violent agitation of the mercury in the mortar box, however, could cause the mercury to break into myriad tiny globules that were carried away by the water with the tailings, thus losing a certain amount of gold in the process (thompson 1867; ritchie & hooker 1997). the water and sand slurry was splashed by the falling stamps from the box through fine mesh screens and onto inclined wooden tables below the mortar box (figure 2). the tables were covered with copper sheets or plates coated with mercury, which caught and amalgamated with a portion of the gold. the grey putty-like amalgam was periodically scraped off the sheets and retorted in a furnace to collect the gold and recover the mercury for reuse. mercury was inevitably lost from the plates, while poor maintenance resulted in further losses of gold and mercury in the tailings. mercury use and loss from gold mining in 19th century victoria. peter davies1, susan lawrence, and jodi turnbull, department of archaeology and history, la trobe university.
