There are 17 opal fields in Australia. This opal bearing stone was found in Lightning Ridge, NSW over what is known as the Great Australian Basin. This basin was formed and covers an area of 1.7 million square kilometers in eastern Australia in the Cretaceous period. This basin used to contain an inland sea, which provided an environment where silcrete eventually formed when water levels changed. This eventually seeped into other structures, and eventually hardened and formed opal. Lightning Ridge has a population of around 2000 people, with about 80 000 visitors every year. It is a historic mining town, and is known for its deposits of a rare black opal. Mining started in the area in the late 1800s, early 1900s when the black opal was discovered. This opal-bearing stone is of social and historical significance. It is from Lightning Ridge, which is well-known for being a large producer of opal stones, most famously black opal. The history of the period dates back to 140 million years, with the discovery of black opal in the early 1900s causing interest in the area. 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 solid mineral specimen in shades of beige and light orange*** silica based? burke museum, beechworth, geological, geological specimen, opal, opal fields, australia, lightning ridge, new south wales, great australian basin, cretaceous, silcrete, black opal, mining

The Ovens pottery operated from 1881 to1892 they had taken over H L & E pottery at Beechworth in 1888 but mounting debts forced the Ovens company to close in 1892. During their short ten years of operation they produced stoneware garden urns, vases, cheese dishes, ginger beer bottles, butter coolers, water filters, wine and spirit barrels, bread plates, jugs, teapots, storage jars, pots, tiles, flower pots, spittoons, basins, bowls, demijohns, lidded crocks, pipes and bricks.A significant item made by an early Australian pottery in Beechworth Victoria, this company made many utilitarian items for the Victorian domestic market. It gives us today a snapshot into early Australian companies that were unable to sustain manufacturing their products into the 20th century, due in part to the rising imports of cheaper items from overseas.Red terracotta butter cooler comprising, round base with ridged lip, and bell shaped, domed lid with spherical handle on topMarked "Ovens Pottery, Co Ltd, Patd 1890, Beechworth" flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, flagstaff hill maritime village, great ocean road, cooler, terracotta cooler, utensil, kitchen ware, terracotta, food container, food preservation, butter cooler, ovens pottery

A windmill may be considered one of the most iconic sights of Australian Farming life. A pump like this rest at the heart of all such windmills, turning wind energy into water for farmers both here in Australia and worldwide alike. The water windmills access is referred to as an aquifer, an underground layer of water trapped in rocks but accessible with use of water wells and windmills. Australia is home to an underground aquifer known as the Great Artesian Basin. It is the largest and deepest aquifer in the world. Stretching over 1,700,000 square kilometres, the Basin underlies nearly a quarter of the continent including most of Queensland, the south- east corner of the Northern Territory, the north-east part of South Australia and the northern part of New South Wales. The basin is 3,000 metres deep in places and is estimated to contain 64,900 cubic kilometres of groundwater. To try and give this number context, a megalitre is a million litres. The Great Artesian Basin contains 65,000 million megalitres of water. This would be enough to cover all the land on the planet in almost half a metre of water.Lift style piston pump typical of an Australian farm connected to a multi-bladed windmill.
