Geological specimen - Chalcedony
This specimen was recovered from Philip Island in Victoria. Chalcedony is composed of Quartz and Silicon Dioxide represented as SIO2. It has and is still used as a gemstone for thousands of years. This is an excellent specimen Chalcedony that shows its aesthetic properties. 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.

Geological specimen - Smoky quartz crystals, unknown
Quartz is an extremely common mineral to find across the world. Quartz can have two forms; Microcrystalline quartz or Crystalline quartz. Microcrystalline quartz is a fine grain quartz where crystalline quartz is often a large crystal. This specimen is a crystalline quartz. Made of silicon oxide, this specimen is called smokey quartz crystals because of its brownish colour. However, the colour of quartz can vary. In addition, quartz are formed in deep-seated igneous rocks and crystallized through hot aqueous solutions. This type of crystal can be found all over Australia, including Beechworth in Victoria. Other places quartz can be found is the Ashburton River area in Western Australia, Marlborough in Queensland, the Lune River area in Tasmania and Kingsgate in New South Wales. This specimen is significant because it is common to find this kind of mineral. While the location of where this specimen was originally from is unknown, it highlights the many places in Australia where quartz is found. It demonstrates that quartz makes up a large portion of Australia's geology. In addition, quartz itself can vary in its colour and shape. This specimen represents one of these variations. That being smoky quartz crystals. 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.

Geological specimen - Cassiterite
This specimen is Cassiterite in Quartz. Cassiterite is a tin oxide metal that forms in thin crystals which can have a beautiful lustre. Quartz is made of silicon dioxide, also known as silica, and is one of the most common minerals on earth. Cassiterite has been a fundamental source of tin ore for humans throughout history, including today. Tin is an important metal that has a wide variety of human uses in different areas, from dying fabric, to making mirrors, and their most well-known use ‘tin’ cans. Tin cans are primarily made of steel and are coated with tin in order to take advantage of tin’s property of being non-corroding. This is a massive step in the history of food preservation. Tinned food first reached Australia in 1815 with early settlers, and it began to be manufactured here in the 1840s. It was incredibly popular, and was a highly exported product, which would be a contributing factor to the ‘tin mining boom’ of the early 1880s. This specimen was collected at Jingellic, New South Wales, in about 1852. Although the Goldfields of the 1800s are much more well-known, tin mines existed alongside the gold mines which began in the mid 19th century and extended almost one hundred years, to the mid 20th century. Specimens like this would have been used as evidence to justify tin mining operations in the region as an investment. 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. The Geological Survey of Victoria was headed by British geologist, Alfred Richard Cecil Selwyn (1824-1902), who was responsible for issuing over 60 geological maps during his 17 years as director. These maps were all hand-drawn and coloured and became the benchmark for accuracy for geological mapping. 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 fist-sized solid geological specimen made on one half of tin oxide, which is dark grey, and on the other side of silica, which is brown and cream.burke museum, beechworth, geological, geological specimen -

Container - Bowl, Late 19th or early 20th Century
Human beings appear to have been making their own ceramics for at least 26,000 years, subjecting clay and silica to intense heat to fuse and form ceramic materials. The earliest found so far were in southern central Europe and were sculpted figures, not dishes. The earliest known pottery was made by mixing animal products with clay and baked in kilns at up to 800°C. While actual pottery fragments have been found up to 19,000 years old, it was not until about ten thousand years later that regular pottery became common. An early people that spread across much of Europe is named after its use of pottery, the Corded Ware culture. These early Indo-European peoples decorated their pottery by wrapping it with rope, while still wet. When the ceramics were fired, the rope burned off but left a decorative pattern of complex grooves on the surface. The invention of the wheel eventually led to the production of smoother, more even pottery using the wheel-forming technique, like the pottery wheel. Early ceramics were porous, absorbing water easily. It became useful for more items with the discovery of glazing techniques, coating pottery with silicon, bone ash, or other materials that could melt and reform into a glassy surface, making a vessel less pervious to water. https://en.wikipedia.org/wiki/CeramicThe discovery and development of ceramics in numerous shapes, form and materials, revolutionised the world.Plain cream ceramic bowl with flat bottom inside.

Domestic object - Strainer
Take a stroll through the average beverage aisle in your supermarket, and you might get the impression that tea has always come in small boxes with disposable tea bags. But before those easy to come by boxes, there was the rich and intriguing history of the tea strainer, a beautiful little tool that has helped our ancestors enjoy loose leaf tea for hundreds of years. Enjoying loose-leaf tea, and becoming familiar with this tool, can help spark an appreciation for your tea strainer and infuser collection, or simply inspire you to grow one. Documentation of tea tools such as the tea strainer appear in ancient history, the earliest models were likely made of bamboo, and later evolved into stainless steel, sterling silver, china, porcelain, silicon, and linen. During the Tang Dynasty in China, a small book called “Classic of Tea” was written describing tea utensils, and they were made to help Buddhist monks keep living things (such as small bugs) out of the drinking water. However, using a tea tool to keep run away tea leaves out of a cup did not become a cited use of the strainer until the 17th century when Dutch merchants made tea more readily available to those outside of the Chinese dynasty. British royals then increased the popularity of tea as their preferred beverage, and it was not long before a newfound fanaticism for tea in Great Britain spread to the American colonies, as did a growing demand for products that could separate loose tea leaves from liquid with ease and flair. Why did people use a strainer to separate out tea leaves in Great Britain and not in China? While the method of serving tea from a teapot with the tea loose in the pot was a practice used in both countries, the reason China may not have required a tool to remove leaves from their cup likely had to do with the types of tea leaves they were producing. The British owned tea plantations, in countries such as India, produced finer black tea leaves that did not require as much space to expand inside of a tea pot, where as the leaves prepared on the Chinese plantations would expand far more in the pot, and were therefore less likely to land or be bothersome inside a tea cup. This common approach to serving tea with smaller tea leaves required a solution to avoid ending up with a cup, and mouth, full of tea leaves. The obvious solution was a strainer basket. In the Victorian era, tea strainer baskets, similar to those still used in tea parlors today, were made to sit on top of the cup to capture the leaves when pouring the tea from a tea pot into the individual cups. Another solution was a tea-removing device called a mote spoon. Mote spoons act as search and rescue spoons to remove tea leaves from individual teacups. The tea would be brewed loose in the teapot, so any tea that ended up in the cup could be removed with a long handled spoon with holes in the spoon to remove rogue tea leaves and keep the steeped water in the cup. The handle also helped keep the teapot spout free of leaves and could help unclog any leaves trapped when pouring. Stainless steel tea strainers and tea infusers gained popularity in the late 19th century. Big name tea strainer producers, such as Tiffany and Gorham, could use fine silver to create quality, heavy, and sturdy strainers, for those who could afford it. There were many varieties of strainers at that time, but it was more likely that smaller designers who could not afford to mass-produce these quality strainers out of silver made them into unique shapes to attract consumers with lighter wallets. And borne was the tea strainer we are accustomed to today. Things took an unexpected turn for the tea strainer in the early 1900s when Thomas Sullivan, a tea merchant, shipped out tea samples in small silk bags. Customers did not realize that they were supposed to remove the tea from the bags, and instead boiled the tea, bag and all! The convenience of tossing out the leaves is obvious, and the popularity of tea bags is still seen today. Most premium bags of tea we are accustomed to today are frequently packaged loose for consumption, and when they are available in bags, the leaves are often crowded and do not have enough space to expand. While pyramid tea bags have become a more recent solution to this problem, due to the additional space at the top of the bag, enjoying a variety of quality tea is easier with a tea strainer in your arsenal. Besides, with the wide variety of strainers for your cup or pot in versatile materials such as mesh, silver, or a novelty silicone cartoon shape, loose tea can still reign supreme. Tea strainers sometimes do require more cleanup and measuring, but the experience and quality is always worth the effort. Besides, strainers also allow for mixing favorite tea blends together for an extra dose of delicious creativity! https://www.teamuse.com/article_170413.html The strainer provided the convenience of separating the tea leaves for disposal later.Metal strainer, bowl shaped, with mesh and twisted wire handle.Noneflagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, strainer
