Malachite is a green copper carbonate hydroxide mineral and was one of the first ores used to make copper metal. Malachite has been utilised as a gemstone and sculptural material in the past as its distinctive green color does not fade when exposed to light or after long periods of time. Malachite is formed at shallow depths in the ground, in the oxidizing zone above copper deposits. The material has also been used as a pigment for painting throughout history. Malachite is considered a rare gemstone in that the original deposits for the stones have been depleted leaving behind very few sources. In addition, the use of Malachite as gemstones and sculptural materials remains just as popular today as they were throughout history. It is quite common to cut the stone into beads for jewellery. The fact that Malachite has such a rich colour and one that does not fade with time or when exposed to light makes it particularly rare. Although there is no indication available of the locality from which the specimen was sourced, it is likely that the specimen was collected either in South Australia in the vicinity of the Burra Burra mines or in Victoria as part of programs of geological surveying undertaken in the Nineteenth and Twentieth centuries. 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 solid hand-sized copper carbonate hydroxide mineral with quartz pebbles in red conglomorate matrix presenting shades of cream, brown and green.Existing label: Malachite / (green) in / conglomerate / (white quartz / pebbles / in red matrix /geological specimen, geology, geology collection, burke museum, beechworth, geological, indigo shire, malachite, malachite specimen, australian mines, mines, geological survey, conglomorate, matrix

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.

Agate occurs when amygdales (gas pockets) form in the upper levels of basaltic lava flows. If these pockets or bubbles are iniltrated by water bearing silica in solution, the fluid dries and hardens in layers, forming round or egg shaped nodules or geodes within the rocky matrix. Agate is formed of a silica mineral chalcedony similar to quartz. Although relatively common and semi-precious, agate has been prized since at least 1450 BC - an intricately carved agate seal was found in the 2015 excavation of a grave belonging to a Mycenaeum priest or warrior near Pylos in Greece. Agate is also used in jewellery and other decorative or ritual purposes due to its often striking appearance. These specimens originated in North Queensland, which contains noted agate-fossicking regions such as in the area surrounding Forsayth. They were collected in approximately 1852 as an adjunct to the Geological Survey of Victoria. It was donated to the Museum in 1868. Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century. The identification of sites containing valuable commodities such as gold, iron ore and gemstones in a locality had the potential to shape the development and history of communities and industries in the area. The discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole. The specimens are significant as examples of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.

Fluorite comes in a variety of natural colours and crystal formations and glows under ultraviolet light (the word 'fluorescence' comes from the same etymological source). In its pure form, calcium fluoride, it is a colourless combination of the elements calcium and fluorine, but gains its colour from trace elements that infiltrate or replace calcium within its crystal structure during its formation. Although fluorite crystals polish well and can achieve a high level of lustre, the mineral is very soft (4 on MOHS hardness scale) so it is unsuitable for use in rings and must be handled and stored carefully if used in other forms of jewellery. Most crystals of the mineral are too coarse for decorative purposes but have been mined under the name fluorspar for a variety of commercial and industrial purposes. These include the production of hydrofluoric acid, smelting metal alloys, producing glazes and ceramic finishes and use in medical and dental products. An existing label for this specimen indicates that its origin or collection-point was 'probably USA.' Fluorspar, the form of fluorite used commercially and industrially, was mined in significant quantities in the counties of Hardin and Pope in South-Eastern Illinois throughout the Nineteenth and Twentieth Centuries. Fluorite was made Illinois' state mineral in recognition of its contribution to the state's identity and economy. The specimens are significant as examples of surveying activity undertaken to assess and direct the development of the mineral resource industries, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.The specimen is a piece of purple shaded fluorite (also known as fluorspar), the mineral form of calcium fluoride.

Foam rubber (also known as cellular, sponge, or expanded rubber) refers to rubber that has been manufactured with a foaming agent to create an air-filled matrix structure. Foam rubber was first produced in 1929 by Dunlop researcher chemist Eric Owen using whipped latex. In 1937 isocyanate based materials were first used for the formation of foam rubbers, after World War II styrene-butadiene rubber replaced many natural types of foam. Foam rubbers have been used commercially for a wide range of applications since around the 1940s.

Feldspathic arenites are sandstones that contain less than 90% quartz, and more feldspar than unstable lithic fragments, and minor accessory minerals.Feldspathic sandstones are commonly immature or sub-mature.These sandstones occur in association with cratonic or stable shelf settings. Feldspathic sandstones are derived from granitic-type, primary crystalline, rocks. If the sandstone is dominantly plagioclase, then it is igneous in origin Sandstone features prominently in public buildings throughout Victoria. Most of the sandstone used as dimension stone in the State came from three sources: the Heatherlie quarry in the Grampians (Silurian), the Bacchus Marsh area (Permian), and the Barrabool Hills near Geelong (Cretaceous).Sandstone features prominently in public buildings throughout Victoria, making this specimen special as it shows the materials used by Victorian building companies. Sandstone can also be crushed, crushed stone is used in the construction of roadways and road structures such as bridges, and in buildings, both commercial and residential. 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 feldspar-rich sandstone, a sandstone intermediate in composition between an arkosic sandstone and a quartz sandstone, containing 10% to 25% feldspar and less than 20% matrix material of clay, sericite, and chlorite. Feldspathic arenite containing less than 90 percent of the composition of quartz. Feldspar is the main composition. Feldspathic arenite may contain fragments of unstable rock, and a little amount of other minerals such as mica and heavy minerals. Some feldspathic arenite have pink or red color because of the presence of potassium feldspar or iron oxide. There are also colored light gray to white. These sandstones are usually medium to coarse grained and can contain a high percentage of granules with angular until subangular roundness. The content of the matrix can appear as the rest up to more than 15 percent, and sorting of grains can present as moderate to poorly sorted. Feldspathic sandstones are generally immature in textural maturity. Feldspathic arenite can not be judged from the structure of the sediment. Bedding can emerge from the laminate parallel to the crossbed. Fossils may appear in the layer deposited on the sea. Feldspathic arenites usually appear on the craton or the continental shelf, which can be associated with conglomerate, quartz lithic arenite, carbonate rock, or evaporites. This sandstone may also appear on the succession of sedimentary basins deposited on an unstable or deep sea, and moving arc setting. According to Pettijohn (1963) Arkose make up about 15 percent of all sandstones. Some Arkose formed in situ when the granite and related rocks disintegrate and generate granular sediments. Most of the material feldspathic sandstones derived from primary crystalline granitic rocks, such as granite or metasomatic rocks containing abundant potassium feldspar. Mineral contained in sandstones is mostly a form of plagioclase feldspar derived from quartz diorite or volcanic rock. Feldspar contained on this sandstone comes from arid to cool climates when the chemical weathering process is reduced.sandstone, natural stone, feldspathic sandstone, burke museum, geology, geological, geological specimen

Agate is also used in jewellery and other decorative or ritual purposes due to its often striking appearance. Quartz is found all over Australia, including Beechworth in Victoria. It is formed in deep-seated igneous rocks and crystallized through hot aqueous solutions. It can have two forms; Microcrystalline quartz or Crystalline quartz. Microcrystalline quartz is a fine grain quartz where crystalline quartz is often a large crystal. The colour of quartz can vary. These specimens were collected in Victoria in the vicinity of the Burke Museum. Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century.

The Micro-Professor I Plus (MPF-IP) was a low cost, versatile microcomputer system featuring sophisticated software and hardware capabilities. (MPF-IP) boasted a display panel with the ability to display 20 characters using 16-segment fonts. All 64 standard ASCII characters could be displayed. The operation of the MPF-IP was controlled by an 8k monitor program which resides in the Read Only Memory (ROM). The monitor, aided by 4k Random Access Memory (RAM), enabled the user to enter a comprehensive set of single keystroke commands, making it easier for the user to use the CPU, memory and I/0 devices. This allowed the user to concentrate of microprocessor software development and application design. The system allowed printing at 48 lines per minute, and the ability to permanently record the commands, data, programs, status and other messaged. Each character printed by the printer is in a 5 by 7 dot matrix. Although the prime purpose of the programming was for machine language object code formed as hexadecimal numbers, the Micro-Professor has an embedded Tiny Basic interpreter for which formation of some of the alpha characters using a standard 7 segment display was ingenious. The program memory consisted of non volatile 2 kilobytes electrically programmable ROM whilst the Random Access Memory came with 2 kilobytes of static RAM but could be upgraded to 4 kilobytes by insertion of another chip. The entire memory space of 64 kilobytes was accessible by way of the terminals on the left hand side of the board. Engineering and Science students from the Ballarat School of Mines and the Ballarat College of Advanced Education used a class set (as they were relatively inexpensive at approx. $100 each) during the mid to late 1980s. Student were encouraged to borrow the Micro-Professors in order to assist in learning how to use them. Only one was ever not returned on time. When pressed to return the device the student confessed that his dog had chewed the plastic case. This is still in our collection complete with bite marks! The Micro-Professor used a Zilog Z80 microprocessor. This was the most powerful of the 8 bit microprocessors at the time. Zilog was derived from the Intel 8080 microprocessor. The Z80 had 158 instructions of which the Intel 78 instructions were a subset. The Intel processor continued on through development in the IBM computers as 8086, 80286, 80386, 80486 and later the pentiums. Zilog lost most of its market share when it developed the 16 bit Z8000 microprocessor. Although the microprocessor was excellent, the lack of peripherals caused users to abandon Zilog products.

Prior to carrying out a detailed condition report of the cetacean skeletons, it is useful to have an understanding of the materials we are likely to encounter, in terms of structure and chemistry. This entry invites you to join in learning about the composition of whale bone and oil. Whale bone (Cetacean) bone is comprised of a composite structure of both an inorganic matrix of mainly hydroxylapatite (a calcium phosphate mineral), providing strength and rigidity, as well as an organic protein ‘scaffolding’ of mainly collagen, facilitating growth and repair (O’Connor 2008, CCI 2010). Collagen is also the structural protein component in cartilage between the whale vertebrae and attached to the fins of both the Killer Whale and the Dolphin. Relative proportions in the bone composition (affecting density), are linked with the feeding habits and mechanical stresses typically endured by bones of particular whale types. A Sperm Whale (Physeter macrocephalus Linnaeus, 1758) skeleton (toothed) thus has a higher mineral value (~67%) than a Fin Whale (Balaenoptera physalus Linnaeus, 1758) (baleen) (~60%) (Turner Walker 2012). The internal structure of bone can be divided into compact and cancellous bone. In whales, load-bearing structures such as mandibles and upper limb bones (e.g. humerus, sternum) are largely composed of compact bone (Turner Walker 2012). This consists of lamella concentrically deposited around the longitudinal axis and is permeated by fluid carrying channels (O’Connor 2008). Cancellous (spongy) bone, with a highly porous angular network of trabeculae, is less stiff and thus found in whale ribs and vertebrae (Turner Walker 2012). Whale oil Whales not only carry a thick layer of fat (blubber) in the soft tissue of their body for heat insulation and as a food store while they are alive, but also hold large oil (lipid) reserves in their porous bones. Following maceration of the whale skeleton after death to remove the soft tissue, the bones retain a high lipid content (Higgs et. al 2010). Particularly bones with a spongy (porous) structure have a high capacity to hold oil-rich marrow. Comparative data of various whale species suggests the skull, particularly the cranium and mandible bones are particularly oil rich. Along the vertebral column, the lipid content is reduced, particularly in the thoracic vertebrae (~10-25%), yet greatly increases from the lumbar to the caudal vertebrae (~40-55%). The chest area (scapula, sternum and ribs) show a mid-range lipid content (~15-30%), with vertically orientated ribs being more heavily soaked lower down (Turner Walker 2012, Higgs et. al 2010). Whale oil is largely composed of triglycerides (molecules of fatty acids attached to a glycerol molecule). In Arctic whales a higher proportion of unsaturated, versus saturated fatty acids make up the lipid. Unsaturated fatty acids (with double or triple carbon bonds causing chain kinks, preventing close packing (solidifying) of molecules), are more likely to be liquid (oil), versus solid (fat) at room temperature (Smith and March 2007). Objects Made From the Whaling Industry We all know that men set forth in sailing ships and risked their lives to harpoon whales on the open seas throughout the 1800s. And while Moby Dick and other tales have made whaling stories immortal, people today generally don't appreciate that the whalers were part of a well-organized industry. The ships that set out from ports in New England roamed as far as the Pacific in hunt of specific species of whales. Adventure may have been the draw for some whalers, but for the captains who owned whaling ships, and the investors which financed voyages, there was a considerable monetary payoff. The gigantic carcasses of whales were chopped and boiled down and turned into products such as the fine oil needed to lubricate increasing advanced machine tools. And beyond the oil derived from whales, even their bones, in an era before the invention of plastic, was used to make a wide variety of consumer goods. In short, whales were a valuable natural resource the same as wood, minerals, or petroleum we now pump from the ground. Oil From Whale’s Blubber Oil was the main product sought from whales, and it was used to lubricate machinery and to provide illumination by burning it in lamps. When a whale was killed, it was towed to the ship and its blubber, the thick insulating fat under its skin, would be peeled and cut from its carcass in a process known as “flensing.” The blubber was minced into chunks and boiled in large vats on board the whaling ship, producing oil. The oil taken from whale blubber was packaged in casks and transported back to the whaling ship’s home port (such as New Bedford, Massachusetts, the busiest American whaling port in the mid-1800s). From the ports it would be sold and transported across the country and would find its way into a huge variety of products. Whale oil, in addition to be used for lubrication and illumination, was also used to manufacture soaps, paint, and varnish. Whale oil was also utilized in some processes used to manufacture textiles and rope. Spermaceti, a Highly Regarded Oil A peculiar oil found in the head of the sperm whale, spermaceti, was highly prized. The oil was waxy, and was commonly used in making candles. In fact, candles made of spermaceti were considered the best in the world, producing a bright clear flame without an excess of smoke. Spermaceti was also used, distilled in liquid form, as an oil to fuel lamps. The main American whaling port, New Bedford, Massachusetts, was thus known as "The City That Lit the World." When John Adams was the ambassador to Great Britain before serving as president he recorded in his diary a conversation about spermaceti he had with the British Prime Minister William Pitt. Adams, keen to promote the New England whaling industry, was trying to convince the British to import spermaceti sold by American whalers, which the British could use to fuel street lamps. The British were not interested. In his diary, Adams wrote that he told Pitt, “the fat of the spermaceti whale gives the clearest and most beautiful flame of any substance that is known in nature, and we are surprised you prefer darkness, and consequent robberies, burglaries, and murders in your streets to receiving as a remittance our spermaceti oil.” Despite the failed sales pitch John Adams made in the late 1700s, the American whaling industry boomed in the early to mid-1800s. And spermaceti was a major component of that success. Spermaceti could be refined into a lubricant that was ideal for precision machinery. The machine tools that made the growth of industry possible in the United States were lubricated, and essentially made possible, by oil derived from spermaceti. Whalebone The bones and teeth of various species of whales were used in a number of products, many of them common implements in a 19th century household. Whales are said to have produced “the plastic of the 1800s.” The bone of the whale which was most commonly used wasn’t technically a bone, it was baleen, a hard material arrayed in large plates, like gigantic combs, in the mouths of some species of whales. The purpose of the baleen is to act as a sieve, catching tiny organisms in sea water, which the whale consumes as food. As baleen was tough yet flexible, it could be used in a number of practical applications. And it became commonly known as whalebone. Perhaps the most common use of whalebone was in the manufacture of corsets, which fashionable ladies in the 1800s wore to compress their waistlines. One typical corset advertisement from the 1800s proudly proclaims, “Real Whalebone Only Used.” Whalebone was also used for collar stays, buggy whips, and toys. Its remarkable flexibility even caused it to be used as the springs in early typewriters. The comparison to plastic is apt. Think of common items which today might be made of plastic, and it's likely that similar items in the 1800s would have been made of whalebone. Baleen whales do not have teeth. But the teeth of other whales, such as the sperm whale, would be used as ivory in such products as chess pieces, piano keys, or the handles of walking sticks. Pieces of scrimshaw, or carved whale's teeth, would probably be the best remembered use of whale's teeth. However, the carved teeth were created to pass the time on whaling voyages and were never a mass production item. Their relative rarity, of course, is why genuine pieces of 19th century scrimshaw are considered to be valuable collectibles today. Reference: McNamara, Robert.

Prior to carrying out a detailed condition report of the cetacean skeletons, it is useful to have an understanding of the materials we are likely to encounter, in terms of structure and chemistry. This entry invites you to join in learning about the composition of whale bone and oil. Whale bone (Cetacean) bone is comprised of a composite structure of both an inorganic matrix of mainly hydroxylapatite (a calcium phosphate mineral), providing strength and rigidity, as well as an organic protein ‘scaffolding’ of mainly collagen, facilitating growth and repair (O’Connor 2008, CCI 2010). Collagen is also the structural protein component in cartilage between the whale vertebrae and attached to the fins of both the Killer Whale and the Dolphin. Relative proportions in the bone composition (affecting density), are linked with the feeding habits and mechanical stresses typically endured by bones of particular whale types. A Sperm Whale (Physeter macrocephalus Linnaeus, 1758) skeleton (toothed) thus has a higher mineral value (~67%) than a Fin Whale (Balaenoptera physalus Linnaeus, 1758) (baleen) (~60%) (Turner Walker 2012). The internal structure of bone can be divided into compact and cancellous bone. In whales, load-bearing structures such as mandibles and upper limb bones (e.g. humerus, sternum) are largely composed of compact bone (Turner Walker 2012). This consists of lamella concentrically deposited around the longitudinal axis and is permeated by fluid carrying channels (O’Connor 2008). Cancellous (spongy) bone, with a highly porous angular network of trabeculae, is less stiff and thus found in whale ribs and vertebrae (Turner Walker 2012). Whale oil Whales not only carry a thick layer of fat (blubber) in the soft tissue of their body for heat insulation and as a food store while they are alive, but also hold large oil (lipid) reserves in their porous bones. Following maceration of the whale skeleton after death to remove the soft tissue, the bones retain a high lipid content (Higgs et. al 2010). Particularly bones with a spongy (porous) structure have a high capacity to hold oil-rich marrow. Comparative data of various whale species suggests the skull, particularly the cranium and mandible bones are particularly oil rich. Along the vertebral column, the lipid content is reduced, particularly in the thoracic vertebrae (~10-25%), yet greatly increases from the lumbar to the caudal vertebrae (~40-55%). The chest area (scapula, sternum and ribs) show a mid-range lipid content (~15-30%), with vertically orientated ribs being more heavily soaked lower down (Turner Walker 2012, Higgs et. al 2010). Whale oil is largely composed of triglycerides (molecules of fatty acids attached to a glycerol molecule). In Arctic whales a higher proportion of unsaturated, versus saturated fatty acids make up the lipid. Unsaturated fatty acids (with double or triple carbon bonds causing chain kinks, preventing close packing (solidifying) of molecules), are more likely to be liquid (oil), versus solid (fat) at room temperature (Smith and March 2007). Objects Made From the Whaling Industry We all know that men set forth in sailing ships and risked their lives to harpoon whales on the open seas throughout the 1800s. And while Moby Dick and other tales have made whaling stories immortal, people today generally don't appreciate that the whalers were part of a well-organized industry. The ships that set out from ports in New England roamed as far as the Pacific in hunt of specific species of whales. Adventure may have been the draw for some whalers, but for the captains who owned whaling ships, and the investors which financed voyages, there was a considerable monetary payoff. The gigantic carcasses of whales were chopped and boiled down and turned into products such as the fine oil needed to lubricate increasing advanced machine tools. And beyond the oil derived from whales, even their bones, in an era before the invention of plastic, was used to make a wide variety of consumer goods. In short, whales were a valuable natural resource the same as wood, minerals, or petroleum we now pump from the ground. Oil From Whale’s Blubber Oil was the main product sought from whales, and it was used to lubricate machinery and to provide illumination by burning it in lamps. When a whale was killed, it was towed to the ship and its blubber, the thick insulating fat under its skin, would be peeled and cut from its carcass in a process known as “flensing.” The blubber was minced into chunks and boiled in large vats on board the whaling ship, producing oil. The oil taken from whale blubber was packaged in casks and transported back to the whaling ship’s home port (such as New Bedford, Massachusetts, the busiest American whaling port in the mid-1800s). From the ports it would be sold and transported across the country and would find its way into a huge variety of products. Whale oil, in addition to be used for lubrication and illumination, was also used to manufacture soaps, paint, and varnish. Whale oil was also utilized in some processes used to manufacture textiles and rope.

The British were not interested. In his diary, Adams wrote that he told Pitt, “the fat of the spermaceti whale gives the clearest and most beautiful flame of any substance that is known in nature, and we are surprised you prefer darkness, and consequent robberies, burglaries, and murders in your streets to receiving as a remittance our spermaceti oil.” Despite the failed sales pitch John Adams made in the late 1700s, the American whaling industry boomed in the early to mid-1800s.
