Common Opal is a mineraloid that is non crystallising and is classed as an amorphous silicate, the chemical composition for Opal is SiO2 nH2O. Opals can develop in weathered sedimentary rock typical in arid regions where limited water enters small gaps in the rock, and the silicate is hydrated. Common opals, unlike precious opals, do not exhibit ‘play of colour’ in which the colour appears to change depending on the angle of view. While precious opals are highly valuable and cut as gemstones for jewellery, common opals can be cut into inexpensive gemstones and are also mined for various uses including as ingredients in ceramics, insulation, fillers, and abrasives. The source of this common opal specimen is unknown, but common opals are found around the world, notable deposits are found in Queensland, South Australia, New South Wales, Peru, Kenya, Nevada, Oregon, and Mexico. This common opal specimen is of historic and scientific significance due to its donation in 1868 as part of the Geological Survey of Victoria and as a typical example of uncut common opal. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A palm-sized amorphous (non-crystallising) hydrated silicate mineraloid specimen in shades of brown, orange, and white.Existing label: Common Opal / Locality unknowngeological specimen, geology, geology collection, burke museum, beechworth, common opal, opal, mineraloid, amorphous silicates, hydrated silicate

No information is available on the history of these six examples of pennyweights. A pennyweight was a unit of mass that was equal in weight to 20 grains, one twentieth of an ounce and one 240th of a Troy pound. The abbreviation for a pennyweight is ‘dwt’ (denarius weight). Pennyweights were and are used in the weighing of precious metals and are still used by dentists in the measurement of the metal used in dental crowns etc. These items are of antiquarian interest and will be useful for displays. These are six pennyweights of varying weights – 5 pennyweights, 4, 3, 0.4, 0.5 and 0.6. They appear to be made of brass and the 5, 4 and 3 pennyweights are rounded off rectangles in shape with eight sides. The three smaller weights are rectangular in shape with nipped-off edges. ‘5 dwts’, ‘4 dwts’, ‘3 dwts’ In black labelling, ‘1499.10, 1499.11, 1499.12’ (old cataloguing numbers) pennyweights, warrnambool, denarius weight

Troy ounces are slightly heavier than avoirdupois ounces that we commonly use. 1 troy ounce equals roughly 1 1/8 ounces and is used for the weighing of precious metals and gems. It is believed that the troy ounce dates back to the 16th century to the town of Troyes in Frances. This was a major trading centre for Europe and a standardised for of weights was needed. One troy ounce equalled 480 grains of barley.Four circular Troy weights - three have raised outer edge/lip with weight details imprinted in the centre.

This particular specimen was recovered from two hundred feet down in the Golden Mile in Kalgoorlie, Western Australia. The Golden Mile, named after the estimated sixty million ounces of gold worth around one hundred billion dollars, was the birthplace of the largest gold rush in Australia almost one hundred and thirty years ago when William Brookman and Samuel Pearce leased the Great Boulder mine. The Golden Mile is also the home of the Super Pit, Australia's most well-known mine.The majority of gold deposits will form as a native metal, however, on occasion, it can form a compound with another element, in this case, sulphur. Therefore, this specimen is a rare example of gold naturally forming into a compound mineral with sulphur. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Precious metals are often found in Sulphide Ores, as sulphides usually bind to these metals. They are also extremely symmetrical in crystaline form. Gold-Sulphide Ore occurs when gold forms a natural compound with other elements. In this form, gold can be present in one of two ways. It can be fully immersed in the sulphide, or a portion may be partially free. This specimen has minimal gold visible, with only a few flecks being partially visible.burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, mineralogy, gold-sulphide ore

The image portrays the no longer used High Altar of the Ballarat Cathedral and one of Ballarat's major artworks installed in 1880. It was designed and executed by Leonardi of Carrara, Italy, recognised as one of the premier marble workers in the world at the time. This is the only example of Leonardi's work in Australia.The altar is constructed of inlays of precious stones and antique marbles and the bas-reliefs feature Christ's passion which is also reflected in the Bentley designed Clayton & Bell window behind it. signor leonardi, high altar, carrara, st patrick's cathedral ballarat.

The nested cup weights were designed to make the transport of weights, essential items in most commercial transactions, more convenient. This idea goes back to Roman times. In the nested cup form, a series of weights shaped into cups are set one into the other. Each cup fits precisely into the next, larger sized cup which each larger example weighing exactly twice that of the one previous. The Troy weight system was used for precious metals and gemstones.7 x Brass troy measures of various sizes.

In 2016 the Welcome to Eltham community project started to welcome Syrian refugees into the community and made Welcome Butterflies to say welcome to them. This book includes photos and welcome messages from local residents. The butterlies are based on the Eltham Copper Butterfly, a rare and precious species local to the area and considered a symbol of the beauty and abundance of Eltham that the community wanted to share with the new community. This book was produced as a gift which was presented to each new family. Learn more at https://www.facebook.com/WelcomeToElthamwelcome to eltham, refugees, eltham, butterfly, butterflies

Melbourne-based artist Wendy Black works across screenprinting, painting and drawing. The 1980s saw a rise in campaigns for Antarctica to be designated a World Park to ensure the ongoing protection of its natural resources and its continuation as a peace zone. Black’s screenprint, featuring seals and penguins set against an Arctic icecap, captures the looming threat to the precious flora and fauna of the continent. Text in the lower corner describes Black’s collaboration with the Antarctic and Southern Ocean coalition for which this poster was likely made. Donated by the artist

A short distance upstream from the old wooden Warrandyte Bridge, the Yarra river was at one time dammed to give power to a large wooden waterwheel which drove a plant for crushing gold. Up until around 1908 the waters of the Yarra, pent up by a stone weir, forced their way past this old wheel turning it to crush the precious quartz. In 1925 the reamins of the State Battery were removed. The large water wheel (thanks to the forethought of a local resident, Mr. P. Mackie) was left in its position.This photo forms part of a collection of photographs gathered by the Shire of Eltham for their centenary project book,"Pioneers and Painters: 100 years of the Shire of Eltham" by Alan Marshall (1971). The collection of over 500 images is held in partnership between Eltham District Historical Society and Yarra Plenty Regional Library (Eltham Library) and is now formally known as the 'The Shire of Eltham Pioneers Photograph Collection.' It is significant in being the first community sourced collection representing the places and people of the Shire's first one hundred years.Digital image 4 x 5 inch B&W Negshire of eltham pioneers photograph collection, warrandyte, water wheel, caledonia battery, state battery, warrandyte battery

Assay is a process of metallurgy and chemical analysis used to determine proportions of precious metals in ores and other metallurgy substances such as silver or gold. The process helps identify pollutants present within a sample and can indicate a high level of pollution in a mining site. Stoneware crucibles are used in the fire assay process due to their ability to withstand high temperatures. Fire assay is a three step process where by samples from the mine are ground in a find powder and then mixed with dry powder chemicals. This mixture is heated in a crucible to extreme temperatures (crucible fusion) until all of the powers fuse into a glass like slag. Once this reaction is complete, the contents are poured into a mold and cooled. In step three (known as cupellation) the mixture is separated in a fire assay cupel and once this is complete the cupel with reveal a small bead of precious metals. Established by George Guthrie in 1857 (about 5km north of its current site) and then again seven years later in 1864 after it initially closed, Bendigo Pottery remains one of the most influential and longest running potteries in Australia. Over the years the Pottery has contributed to the growth and development of the district through both its products including building products, table ware and decorative and commemorative war as well as artistically, being responsible for training and supporting many potters locally. It has partnered with the City on various tourism promotions and the Civic Collection holds a number of important items within its collection.Two stoneware vessels of differing dimensions (0287.1 & .2).

Bendigo Advertiser "The way we were" from 1999. Malthouse: The Albion Brewery (Steward Brothers), Eaglehawk, circa 1900. The brewery dates back to 1853. James Steward was born in 1830 at Bury-St-Edmonds, Suffolk, England, and was educated in the brewing of ale before he boarded the American ship, the James L. Logert, bound for Australia in 1852. He made his way to the Bendigo diggings where he soon won his share of the precious metal until 1857 when he purchased a brewery in Letherby's Rd, Sailors Gully. The brewery covered five acres, had a house opposite with creeper covered walls and was described as one of the most attractive in the area.newspaper, bendigo advertiser, the way we were

A shirt stud is a decorative fastener that fits onto a buttonhole on the front of a pleated shirt, or onto the starched bib of a stiff-front shirt. Such shirts have special buttonholes solely for shirt studs. A shirt stud may be fashioned from alloys, precious metals, and gemstones—materials uncommon to buttons sewn on shirts. The stud may have an inlay, such as of pearl or onyx. Dress code of the modern western world reserves shirt studs for men's formal wear and some semi-formal occasions. In the western world, shirt studs were first used in the mid-19th century, when some shirt fronts were too stiff to close with buttons. So remains the case for the heavily starched, modern full dress shirts worn with white tie.

Tourmaline specimens are members of a crystalline silicate mineral group based on boron but influenced by elements including aluminium, iron, magnesium, sodium, lithium, or potassium. Specimens present a wide variety of colours and forms according to the specific mix of these elements. Tourmalines are semi-precious gemstones with many applications, including commercial jewellery production. The word 'tourmaline' derives from the Sinhalese term for the carnelian or red-shaded specimens, "tōramalli". This specimen has been classified by geologists as 'Black Schoalou/Tourmaline in quartz'. Schoalou may equate to a common black-hued type of Tourmaline associated since around 1400 with mines in Saxony, Germany near a village called Schorl (today's Zchorlau). If this specimen is part of the 'Schorl' species of tourmaline it is a member of the most common group of Tourmalines, a divalent sodium ion influenced group accounting for 95% of specimens. On assessment, it was noted that the crossed lines (XIs) of this tourmaline have been fractured and rehealed by the quartz matrix in which the tourmaline rests. This item is significant as an example of its type of gemstone and the geological processes leading to its formation.

Troy weight is a system of units of mass from an unknown origin. While the name Troi is believed to have come from Troyes in the north east of France the system used primarily in the precious metals industry and adopted in Australia originated in 15th century England. Troy weight units are the 'grain' and 'pennyweight' (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). One troy ounce equals 31.1034768 grams. The troy ounce and grain were also part of the apothecaries' system and was long used in medicine, but has now been largely replaced by the metric system (milligrams). When the Weights and Measures Act was passed in Victoria in 1862 local inspectors were established throughout the colony to ensure accuracy particularly in the weighing of gold. By the 1870's each local council had a set of standards that were used to test the scales, weights and measures of local merchants and businesses. This set would have been de commissioned some time after 1947 and was offered back to the Borough of Eaglehawk in 1989. Hinged, lockable wooden box with brass handle, hinges, latches and lock. Remnant wax on front face of box above and below lock. Interior of box is lined with purple velvet which is worn in several places.

This photograph depicts four men standing near a large unidentified building. This building is the entrance to a deep lead mine shaft. There is a bridge entering the building, which was used to access the elevator to the shaft. Deep lead mining involved placing large shafts into the ground which miners use to access deeper locations in order to excavate the rocks in the search for lead. Deep lead mining was highly dangerous as roofs could cave in of the soil was loose. Therefore, this particular mining considered to be highly undesirable profession as many miners did not want to work long hours nor risk their lives in the search for lead. Indigo Shire was a large area where deep lead mining took place, and thus the landscape and environment was largely impacted by these mining businesses. The Indigo Shire grew in population and wealth in the early 1850s when people came into this location in the hopes of finding gold and making a fortune. Ultimately, the accessibility and availability of gold and precious metals decreased once the gold reserves dried up and alongside this, the large population moved away. The Ovens was also heavily impacted environmentally as deep mining resulted in the change in land formation.The search for gold is ingrained into the history of Victoria and therefore, images like this one which portray an open cut sluicing site can reveal important information for society and technology for the date when the photograph was taken. This image is of important historical significance for its ability to convey information about the methods used to find gold in Indigo Shire. It also shows a location where deep mining was undertook which provides insight into the impact of deep mining on the environment at a time when it was done. This image is important for current research into the history of Indigo Shire, a region in Victoria's north-east. Therefore, this image has the capacity to be beneficial for research into society and the motivations of those living and working in this region during this period and therefore, has social significance. The Beechworth Burke Museum has additional images relating to deep lead mining and Indigo Shire which can be analysed and studied alongside images like this one.Sepia coloured retangular photo printed on gloss photographic paper.Reverse: 1997, 2510/ A02570/ Deep Lead Mining/ page 94/ 65%/ Burke Museum, Photo 44beechworth, burke museum, indigo shire, deep lead mining, mining, gold, gold mining

It's encouraging to see my city using poetry in such a public way. The park itself is a humble one, which suits these little poems perfectly. If you're ever in town come and take a seat for a while. The poem 'Little Bridge' by Nathan Curnow was commissioned as part of a placemaking project in Little Bridge Street Pocket Park, Ballarat in 2018. The Park was redesigned to include more passive surveillance, and improved amenity to increase community safety in the area. The poem is engraved onto seating to provide a rest and point of interest space in the small park. Six seats featuring an engraved poemPut it all down and take a seat/ Pull out a snack from your shopping/ Listen to the trumpeter busking a tune/ With every visit this park is growing/ Killing time takes real devotion/ Stare at the flags and masts of your town/ And the buses come rolling down Bakery Hill/ It may be cold but we lean to the sun/ If you feel like a square of the Eureka flag/That’s hopelessly lost and tattered/ Remember you’re as precious as a corner-piece/ We search for you first to get started/ There is something big on Little Bridge/ Not a beanstalk that leads to a giant/ But another day in the life of Ballarat/ All of this gold at the surface poetry, little bridge street, ballarat
