This model of a mechanical ore roasting and chloridising furnace was invented and patented by Thomas Edwards of the Edwards Pyrites Smelting and Ore Reduction Company. This new type of furnace produced a high standard of sulphur free ore known as ‘sweet roasted’. Edwards used this model for demonstrations in the USA. Of note is the central large vertical cogwheel (externally driven) which drives small vertical cogwheels via angled cogging drives. These in turn drive a horizontal wheel. Each side of the vertical wheel is set on an opposite side to the horizontal wheel of its neighbours, resulting in opposite direction rotation of neighbouring horizontal wheels. Each horizontal wheel turns a rabble (set of vertical iron paddles) within the furnace. These rabbles, each turning in opposite direction to its neighbours, move the roasting ore in a zig-zag path through the furnace. The elongated furnace with its line of rabbles produced a much ‘sweeter’ roasted ore than could be obtained from a typical tank-shaped furnace. In 1924, when the model was donated to the Ballarat School of Mines, Ballarat’s Courier newspaper reported, ‘Apart from its historical and education value, the gift should serve to stimulate the inventive faculties of the students who have to win fame for the school and for themselves in the metallurgical world.’ The furnace model was donated to Ballarat School of Mines and used as an educational prop from 1924. The model relates to the mining industry which is a significant part of Ballarat's history and heritage. Ballarat School of Mines is the oldest Technical School in Australia and is celebrating 150 years in 2020.Metal model of Edwards' Ore Reduction Furnace. The model includes cogwheels, rabbles and other details. Scale is thought to be around 1:20M259ballarat school of mines, edwards, pyrites, ore reducation, edward retallack, mining, model

The depicted Ballarat School of Mines Assaying Furnace probably dates back to the mid 1890s. The photo first appears in the Ballarat School of Mines Calendar for 1900, but references to these facilities were mentioned in 1887. These facilities were updated and expanded on several occasions. Black and white photograph of the assay furnaces at the Ballarat School of Mines. The Assay-room contained 16 smelting furnaces, 16 muffle furnaces fro coke, charcoal, bituminous coal and gas, and featured all the usual tools and appliances.

R.M. Serjeant was listed as a mining manager and Joseph Flude as a metallurgist. In 1875 they were both living in Ballarat. The patent number is A.D.1875, 4th March. No 2031. According to the patent the hearth of the furnace is in the form of a cone revolving horizontally. The feed is supplied to the apex of the cone by an archimedian screw. The crown of the furnace comprises a double covering or roof with an intermediate chamber for receiving heated air. The inner covering is pierced to admit of the heated air being brought into contact with the pyrites on the face of the revolving hearth. The discharge of the roasted substance is affected by means of a scraper at the base of the cone. It was claimed that this was a new mode of introducing heated air, and the exclusion of flame during the operation of roasting pyrites. The self-acting charge and discharge of the furnace and the peculiar construction of the hot air chambers, and the use of perforated bricks through which the supply of air is affected were also new.

The extraction of the gold from pyrites and the utilization for commercial purposes of other substances connected with pyrites are peculiarly important to Ballarat, because were a simple and inexpensive method devised there are millions and millions of tons of quartz that would then be made remunerative.

After clean up of stamper table, amalgam is placed in a retort, then placed in the furnace where mercury is condensed and runs down the small pipe into an enamel bucket and can be reused. This is one of a series of photographs of the Rutherglen Gold Battery. The battery's purpose was to crush quartz from nearby quartz reefs and extract gold from within. The battery was erected in 1908 and consists of a five-head battery, Wilfrey table, Bergin pan, portable steam engine and shed. The battery was restored in 2011/12 and can be viewed daily between 9.00am and 5.00pm.

This tuyere (word from French origin) was used by professional blacksmiths and or cattlemen before and during the Kiewa Hydro Electricity Scheme was being constructed. The need to use a furnace or forge in the shaping of metal rods, horse shoes and pipes is both a rural necessity and a construction, on site requirement. The "inventiveness" of cattlemen and construction workers to produce metal objects not available "off the shelf" is one of the inherent traits not only of rural self sufficiency but in the "pioneer" days of rural isolation one of survival.This tuyere is of great significance to the Kiewa Valley and its regions because it highlights one of the greatest strengths of the rural (especially isolated) life and its folk living there, and that is the great human factor of adaptability and survival techniques in sometimes harsh and demanding environmental circumstances. The inventiveness and the attitude, "she'll be right mate", demonstrates life on the land where specialised blacksmith activities can be found in non "professionals" because of the fact that "someone" has to do the job. This is one of the differences between country "rural" life and that found in cities and larger towns.This iron cone shaped tuyere has a small hole (diamenter 25mm) starting within an ever enlarging cone (amplification of the air pressure going through) delivering varying hot or extremely hot air into a furnace or hearth which intensifies the heat to allow the "shaping" of metal objects. The larger "flared" cone extension allows for the directed air to be spread and not concentrated.blacksmith tool, tue, bellows, fashioning metal, forge manufacturing process

James Oddie was Vice-President of the Ballarat School of Mines in 1886.Blue, lined, foolscap paper from Ballarat School of Mines Logo. It is handwritten by James Oddie for the Ballarat School of Mine Council and is in regards to the duties of Professor Ferdinand Krause."The Vice-President submits the following statement for consideration by the Council: - On Tuesday 1st June between 2 and 3 o'clock in the afternoon I called on Professor Krause and requested him to prepare plans and sections with a view to the erection of furnaces, machinery, and appliances which the committee appointed by Council had resolved upon obtained for the School. Mr Krause at once refused, urging that this work was outside his duties, but that he would be willing to undertake it if allowed a remuneration of 5% which was 2 1/2 % less than a professional engineer would charge. He took exception to a paragraph that appeared in the "Ballarat Star" of the 28th May which referred to the visit and inspection of the Honorary Staff or mechanical engineers on the day previous. He further stated that he was not going to be a shoeblack to these persons and his language and manner was generally offensive and insubordinate. The progress of the work is thus considerably delayed. James Oddie"ballarat school of mines, oddie, krause, mining, furnace, james oddie, ferdinand krause
