In the 2021 census , the population of Inverell was 12,057 and the Inverell Shire population
216-749: A federal territory , as have the areas now known as the Australian Capital Territory and the Jervis Bay Territory . The original inhabitants of New South Wales were the Aboriginal tribes who arrived in Australia about 40,000 to 60,000 years ago. Before European settlement there were an estimated 250,000 Aboriginal people in the region. The Wodi wodi people, who spoke a variant of the Dharawal language, are
324-686: A deal with Edmund Barton , leader of the NSW Protectionist Party, whereby they would work together for federation and leave the question of a protective tariff for a future Australian government to decide. In early 1893 the first citizens' Federation League was established in the Riverina region of New South Wales and many other leagues were soon formed in the colony. The leagues organised a conference in Corowa in July 1893 which developed
432-530: A debt crisis after the onset of the Great Depression in 1929. New South Wales was hit harder by the depression than other states, and by 1932 one third of union members in the state were unemployed, compared with 20 per cent nationally. Labor won the November 1930 NSW elections and Jack Lang became premier for the second time. In 1931 Lang proposed a plan to deal with the depression which included

Baird resigned as Premier on 23 January 2017, and was replaced by Gladys Berejiklian . On 23 March 2019, Berejiklian led the Coalition to a third term in office. She maintained high personal approval ratings for her management of a bushfire crisis and the COVID-19 pandemic . However, Berejiklian resigned as premier on 5 October 2021, following
756-688: A hereditary upper house was widely ridiculed and subsequently dropped. The property qualification for voters had been reduced in 1851, and by 1856 95 per cent of adult males in Sydney, and 55 per cent in the colony as a whole, were eligible to vote. Full adult male suffrage was introduced in 1858. In 1859 Queensland became a separate colony. In 1861 the NSW parliament legislated land reforms intended to encourage family farms and mixed farming and grazing ventures. The amount of land under cultivation subsequently increased from 246,000 acres in 1861 to 800,000 acres in
864-665: A huge victory for Holman's pro-conscription Nationalists in the elections of March 1917, a second referendum on conscription held in December that year was defeated in New South Wales and nationally. Following the war, NSW governments embarked on large public works programs including road building, the extension and electrification of the rail network and the construction of the Sydney Harbour Bridge. The works were largely funded by loans from London, leading to
972-487: A large scale was bronze , made of 1 ⁄ 8 tin and 7 ⁄ 8 copper (12.5% and 87.5% respectively), from as early as 3000 BC. After 600 BC, pure metallic tin was produced. Pewter , which is an alloy of 85–90% tin with the remainder commonly consisting of copper , antimony , bismuth, and sometimes lead and silver, has been used for flatware since the Bronze Age . In modern times, tin
1080-541: A major "tin crisis" ensued—tin was delisted from trading on the London Metal Exchange for about three years. ITC dissolved soon afterward, and the price of tin, now in a free-market environment, fell to $ 4 per pound and remained around that level through the 1990s. The price increased again by 2010 with a rebound in consumption following the 2007–2008 economic crisis , accompanying restocking and continued growth in consumption. London Metal Exchange (LME)
1188-583: A majority of one seat. The outbreak of the First World War in 1914 saw more NSW volunteers for service than the federal authorities could handle, leading to unrest in camps as recruits waited for transfer overseas. In 1916 NSW premier William Holman and a number of his supporters were expelled from the Labor party over their support for military conscription. Holman subsequently formed a Nationalist government which remained in power until 1920. Despite

In 1839, the UK decided to formally annex at least part of New Zealand to New South Wales. It was administered as a dependency until becoming the separate Colony of New Zealand on 3 May 1841. From the 1820s, squatters increasingly established unauthorised cattle and sheep runs beyond
1404-532: A phenomenon known as " tin pest " or "tin disease". Some unverifiable sources also say that, during Napoleon 's Russian campaign of 1812, the temperatures became so cold that the tin buttons on the soldiers' uniforms disintegrated over time, contributing to the defeat of the Grande Armée , a persistent legend. The α-β transformation temperature is 13.2 °C (55.8 °F), but impurities (e.g. Al, Zn, etc.) lower it well below 0 °C (32 °F). With
1512-507: A plan for federation. The new NSW premier, George Reid , endorsed the "Corowa plan" and in 1895 convinced the majority of other premiers to adopt it. A constitutional convention held sessions in 1897 and 1898 which resulted in a proposed constitution for a Commonwealth of federated states. However, a referendum on the constitution failed to gain the required majority in New South Wales after that colony's Labor party campaigned against it and premier Reid gave it such qualified support that he earned
1620-641: A planner to design the street layout of Sydney. A road across the Blue Mountains was completed in 1815, opening the way for large scale farming and grazing in the lightly wooded pastures west of the Great Dividing Range . In 1825 Van Diemen's Land (now Tasmania) became a separate colony and the western border of New South Wales was extended to the 129th meridian east (now the West Australian border). New South Wales established
1728-402: A result of twinning in tin crystals. Tin is a post-transition metal in group 14 of the periodic table of elements. It is obtained chiefly from the mineral cassiterite , which contains stannic oxide , SnO 2 . Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead , and has two main oxidation states , +2 and the slightly more stable +4. Tin

At least 39 convicts were killed in the uprising and subsequent executions. Lachlan Macquarie (governor 1810–1821) commissioned the construction of roads, wharves, churches and public buildings, sent explorers out from Sydney, and employed
1944-552: A solution with most metals and elements so tin does not have much solid solubility. Tin mixes well with bismuth , gallium , lead , thallium and zinc , forming simple eutectic systems. Tin becomes a superconductor below 3.72 K and was one of the first superconductors to be studied. The Meissner effect , one of the characteristic features of superconductors, was first discovered in superconducting tin crystals. Tin resists corrosion from water , but can be corroded by acids and alkalis . Tin can be highly polished and
2052-511: A suspension of interest payments to British creditors, diverting the money to unemployment relief. The Commonwealth and state premiers rejected the plan and later that year Lang's supporters in the Commonwealth parliament brought down James Scullin's federal Labor government. The NSW Lang government subsequently defaulted on overseas interest payments and was dismissed from office in May 1932 by
2160-608: A tin or tin-lead coolant, the tin would first have to go through isotopic separation to remove the isotopes with odd mass number. Combined, these three isotopes make up about 17% of natural tin but represent nearly all of the capture cross section. Of the remaining seven isotopes tin-112 has a capture cross section of 1 barn. The other six isotopes forming 82.7% of natural tin have capture cross sections of 0.3 barns or less, making them effectively transparent to neutrons. Tin has 31 unstable isotopes, ranging in mass number from 99 to 139. The unstable tin isotopes have half-lives of less than

When a bar of tin is bent a crackling sound known as the " tin cry " can be heard from the twinning of the crystals. This trait is shared by indium , cadmium , zinc , and mercury in its solid state. Tin melts at about 232 °C (450 °F), the lowest in group 14, and boils at 2,602 °C (4,716 °F),
2700-473: Is evidence that Cornwall in the first centuries AD was the main source of tin. Tin extraction and use can be dated to the beginnings of the Bronze Age around 3000 BC, when it was observed that copper objects formed of polymetallic ores with different metal contents had different physical properties. The earliest bronze objects had a tin or arsenic content of less than 2% and are believed to be

3456-528: Is the least common stable isotope. The isotopes with even mass numbers have no nuclear spin , while those with odd mass numbers have a nuclear spin of 1/2. It is thought that tin has such a great multitude of stable isotopes because of tin's atomic number being 50, which is a " magic number " in nuclear physics. Tin is one of the easiest elements to detect and analyze by NMR spectroscopy , which relies on molecular weight and its chemical shifts are referenced against tetramethyltin ( SnMe 4 ). Of

Minerals with tin are almost always associated with granite rock, usually at a level of 1% tin oxide content. Because of the higher specific gravity of tin dioxide, about 80% of mined tin is from secondary deposits found downstream from
3672-587: Is tin's principal trading site. Other tin contract markets are Kuala Lumpur Tin Market (KLTM) and Indonesia Tin Exchange (INATIN). Due to factors involved in the 2021 global supply chain crisis , tin prices almost doubled during 2020–21 and have had their largest annual rise in over 30 years. Global refined tin consumption dropped 1.6 percent in 2020 as the COVID-19 pandemic disrupted global manufacturing industries. In 2018, just under half of all tin produced
3780-425: Is used as a protective coat for other metals. When heated in air it oxidizes slowly to form a thin passivation layer of stannic oxide ( SnO 2 ) that inhibits further oxidation. Tin has ten stable isotopes , the greatest number of any element. Their mass numbers are 112, 114, 115, 116, 117, 118, 119, 120, 122, and 124. Tin-120 makes up almost a third of all tin. Tin-118 and tin-116 are also common. Tin-115

Both reverberatory furnace and electric furnace can be used: The ten largest tin-producing companies produced most of
5292-496: The addition of antimony or bismuth the transformation might not occur at all, increasing durability. Commercial grades of tin (99.8% tin content) resist transformation because of the inhibiting effect of small amounts of bismuth, antimony, lead, and silver present as impurities. Alloying elements such as copper, antimony, bismuth, cadmium, and silver increase the hardness of tin. Tin easily forms hard, brittle intermetallic phases that are typically undesirable. It does not mix into

7452-608: The necessary enabling legislation in 1900 and Western Australia subsequently voted to join the new federation. The Commonwealth of Australia was inaugurated on 1 January 1901, and Barton was sworn in as Australia's first prime minister. The first post-federation NSW governments were Progressive or Liberal Reform and implemented a range of social reforms with Labor support. Women won the right to vote in NSW elections in 1902, but were ineligible to stand for parliament until 1918. Labor increased its parliamentary representation in every election from 1904 before coming to power in 1910 with
7560-460: The nickname "yes-no Reid". The premiers of the other colonies agreed to a number of concessions to New South Wales (particularly that the future Commonwealth capital would be located in NSW), and in 1899 further referendums were held in all the colonies except Western Australia. All resulted in yes votes, with the yes vote in New South Wales meeting the required majority. The Imperial Parliament passed
7668-504: The offer of a public service position to a former Liberal MP. Greiner resigned but was later cleared of corruption. His replacement as Liberal leader and Premier was John Fahey , whose government narrowly lost the 1995 election to the ALP under Bob Carr , who was to become the longest serving premier of the state. The Carr government (1995–2005) largely continued its predecessors' focus on the efficient delivery of government services such as health, education, transport and electricity. There
7776-503: The official limits of the settled colony. In 1836, an annual licence was introduced in an attempt to control the pastoral industry, but booming wool prices and the high cost of land in the settled areas encouraged further squatting. The expansion of the pastoral industry led to violent episodes of conflict between settlers and traditional Aboriginal landowners, such as the Myall Creek massacre of 1838. By 1844 wool accounted for half of
7884-579: The opening of an ICAC investigation into her actions between 2012 and 2018. She was replaced by Dominic Perrottet . New South Wales is bordered on the north by Queensland, on the west by South Australia, on the south by Victoria and on the east by the Coral and Tasman Seas . The Australian Capital Territory and the Jervis Bay Territory form a separately administered entity that is bordered entirely by New South Wales. The state can be divided geographically into four areas. New South Wales's three largest cities, Sydney , Newcastle and Wollongong , lie near
7992-611: The original custodians of an area south of Sydney which was approximately bounded by modern Campbelltown , Shoalhaven River and Moss Vale and included the Illawarra . The Bundjalung people are the original custodians of parts of the northern coastal areas . There are other Aboriginal peoples whose traditional lands are within what is now New South Wales, including the Wiradjuri , Gamilaray , Yuin , Ngarigo , Gweagal , and Ngiyampaa peoples. In 1770, James Cook charted
8100-570: The population of New South Wales was over 8.3 million, making it Australia's most populous state. Almost two-thirds of the state's population, 5.3 million, live in the Greater Sydney area. The Colony of New South Wales was founded as a British penal colony in 1788. It originally comprised more than half of the Australian mainland with its western boundary set at 129th meridian east in 1825. The colony then also included
8208-651: The primary east–west routes through New South Wales. Thunderbolts Way terminates at Copes Creek, 16 km south of the Gwydir Highway intersection at Inverell. Bus services in Inverell are provided by Inverell Bus Service, which operates two town loops, to the east and west. Interurban bus service is provided by Symes Coaches to Glen Innes . NSW TrainLink operates three Coach services in and out of Inverell: between Moree and Grafton , between Inverell and Tamworth via Manilla and between Inverell and Armidale via Tingha . The most popular sport in Inverell
8316-613: The primary lodes. Tin is often recovered from granules washed downstream in the past and deposited in valleys or the sea. The most economical ways of mining tin are by dredging , hydraulicking , or open pits . Most of the world's tin is produced from placer deposits, which can contain as little as 0.015% tin. About 253,000 tonnes of tin were mined in 2011, mostly in China (110,000 t), Indonesia (51,000 t), Peru (34,600 t), Bolivia (20,700 t) and Brazil (12,000 t). Estimates of tin production have historically varied with
8424-472: The reaction of hydrochloric acid and tin produces SnCl 2 and hydrogen gas. Alternatively SnCl 4 and Sn combine to stannous chloride by a process called comproportionation : Tin can form many oxides, sulfides, and other chalcogenide derivatives. The dioxide SnO 2 (cassiterite) forms when tin is heated in the presence of air . SnO 2 is amphoteric , which means that it dissolves in both acidic and basic solutions. Stannates with
8532-456: The result of unintentional alloying due to trace metal content in the copper ore. The addition of a second metal to copper increases its hardness, lowers the melting temperature, and improves the casting process by producing a more fluid melt that cools to a denser, less spongy metal. This was an important innovation that allowed for the much more complex shapes cast in closed molds of the Bronze Age. Arsenical bronze objects appear first in
8640-415: The second lowest (ahead of lead ) in its group. The melting point is further lowered to 177.3 °C (351.1 °F) for 11 nm particles. β-tin, also called white tin , is the allotrope (structural form) of elemental tin that is stable at and above room temperature. It is metallic and malleable, and has body-centered tetragonal crystal structure. α-tin, or gray tin , is the nonmetallic form. It
8748-442: The settler population of New South Wales had grown to 180,000, not including the 70,000 living in the area which became the separate colony of Victoria in 1851. In 1856 New South Wales achieved responsible government with the introduction of a bicameral parliament comprising a directly elected Legislative Assembly and a nominated Legislative Council . William Charles Wentworth was prominent in this process, but his proposal for
8856-470: The southern side of Byron Plains. He named his run 'Inverell', the word being of Gaelic origin, and signifies "meeting place of the swans"; from Inbhir , a confluence , and eala , a swan. In the initial years, the local Aboriginal people resisted this occupation by spearing MacIntyre's shepherds and taking his livestock. Inverell is at the junction of the MacIntyre River and Swanbrook Creek and
8964-586: The stable isotopes, tin-115 has a high neutron capture cross section for fast neutrons, at 30 barns . Tin-117 has a cross section of 2.3 barns, one order of magnitude smaller, while tin-119 has a slightly smaller cross section of 2.2 barns. Before these cross sections were well known, it was proposed to use tin-lead solder as a coolant for fast reactors because of its low melting point. Current studies are for lead or lead-bismuth reactor coolants because both heavy metals are nearly transparent to fast neutrons, with very low capture cross sections. In order to use
9072-439: The state's south-west. Regional cities such as Albury , Dubbo , Griffith and Wagga Wagga and towns such as Deniliquin , Leeton and Parkes exist primarily to service these agricultural regions. The western slopes descend slowly to the western plains that comprise almost two-thirds of the state and are largely arid or semi-arid. The mining town of Broken Hill is the largest centre in this area. One possible definition of
9180-678: The structure [ Sn(OH) 6 ] , like K 2 [ Sn(OH) 6 ], are also known, though the free stannic acid H 2 [ Sn(OH) 6 ] is unknown. Sulfides of tin exist in both the +2 and +4 oxidation states: tin(II) sulfide and tin(IV) sulfide ( mosaic gold ). Stannane ( SnH 4 ), with tin in the +4 oxidation state, is unstable. Organotin hydrides are however well known, e.g. tributyltin hydride (Sn(C 4 H 9 ) 3 H). These compounds release transient tributyl tin radicals, which are rare examples of compounds of tin(III). Organotin compounds, sometimes called stannanes, are chemical compounds with tin–carbon bonds. Of
9288-413: The supermarket since the early 90s. There are two primary schools in Inverell; Ross Hill School and Inverell Public School. The two local high schools are Inverell High School and Macintyre High School. Holy Trinity School is a Roman Catholic School in Inverell which caters for students from Kindergarten to Year Ten. Inverell is served by Inverell Airport . Inverell lies on the Gwydir Highway , one of
9396-420: The tetrafluoride is polymeric. All four halides are known for Sn(II) also: SnF 2 , SnCl 2 , SnBr 2 , and SnI 2 . All are polymeric solids. Of these eight compounds, only the iodides are colored. Tin(II) chloride (also known as stannous chloride) is the most important commercial tin halide. Illustrating the routes to such compounds, chlorine reacts with tin metal to give SnCl 4 whereas
9504-523: The tetraorgano derivatives, are prepared by redistribution reactions : Divalent organotin compounds are uncommon, although more common than related divalent organogermanium and organosilicon compounds. The greater stabilization enjoyed by Sn(II) is attributed to the " inert pair effect ". Organotin(II) compounds include both stannylenes (formula: R 2 Sn, as seen for singlet carbenes ) and distannylenes (R 4 Sn 2 ), which are roughly equivalent to alkenes . Both classes exhibit unusual reactions. Tin
9612-498: The threat of invasion by Japan, which entered the war in December 1941. In May 1942 three Japanese midget submarines entered Sydney harbour and sank a naval ship, killing 29 men aboard. The following month Sydney and Newcastle were shelled by Japanese warships. American troops began arriving in the state in large numbers. Manufacturing, steelmaking, shipbuilding and rail transport all grew with the war effort and unemployment virtually disappeared. A Labor government led by William McKell
9720-588: The tin compounds, the organic derivatives are commercially the most useful. Some organotin compounds are highly toxic and have been used as biocides . The first organotin compound to be reported was diethyltin diiodide ((C 2 H 5 ) 2 SnI 2 ), reported by Edward Frankland in 1849. Most organotin compounds are colorless liquids or solids that are stable to air and water. They adopt tetrahedral geometry. Tetraalkyl- and tetraaryltin compounds can be prepared using Grignard reagents : The mixed halide-alkyls, which are more common and more important commercially than
9828-426: The tourist industry in the Snowy Mountains . Agriculture, particularly the wool industry, is important throughout the highlands. Major centres include Armidale , Bathurst , Bowral , Goulburn , Inverell , Orange , Queanbeyan and Tamworth . There are numerous forests in New South Wales, with such tree species as Red Gum Eucalyptus and Crow Ash ( Flindersia australis ), being represented. Forest floors have
9936-561: The unmapped eastern coast of the continent of New Holland , now Australia, and claimed the entire coastline that he had just explored as British territory. Contrary to his instructions, Cook did not gain the consent of the Aboriginal inhabitants. Cook originally named the land New Wales , however, on his return voyage to Britain he settled on the name New South Wales . In January 1788 Arthur Phillip arrived in Botany Bay with
10044-606: The world's tin in 2007. Most of the world's tin is traded on LME, from 8 countries, under 17 brands. The International Tin Council was established in 1947 to control the price of tin. It collapsed in 1985. In 1984, the Association of Tin Producing Countries was created, with Australia, Bolivia, Indonesia, Malaysia, Nigeria, Thailand, and Zaire as members. Tin is unique among mineral commodities because of
10152-551: Was 17,853. Prior to British colonisation, the Jukambal and Weraerai Aboriginal peoples lived in and occupied this region. Around 1838, colonist Peter MacIntyre directed his employee, Alexander Campbell, to take up land in the area for his sheep and cattle. Campbell subsequently laid claim to a large section of pastureland along the Macintyre River , which he called 'Byron Plains' after Peter Byron, one of MacIntyre's stockmen. Campbell later staked out 50,000 acres for himself on
10260-458: Was able to restrain the price during periods of high prices by selling from the stockpile. This was an anti-free-market approach, designed to assure a sufficient flow of tin to consumer countries and a profit for producer countries. However, the buffer stockpile was not sufficiently large, and during most of those 29 years tin prices rose, sometimes sharply, especially from 1973 through 1980 when rampant inflation plagued many world economies. During
10368-470: Was able to transform this narrow one seat victory into landslide wins (known as Wranslides) in 1978 and 1981. After winning a comfortable though reduced majority in 1984, Wran resigned as premier and left parliament. His replacement Barrie Unsworth struggled to emerge from Wran's shadow and lost a 1988 election against a resurgent Liberal Party led by Nick Greiner . The Greiner government embarked on an efficiency program involving public sector cost-cutting,
10476-566: Was also known as "Green Swamp" in the 1850s. Wheat growers, Colin and Rosanna Ross established a store there in 1853, and it was proposed that a town be surveyed. In 1858, this was done and in the following years the plan was approved and the first land sale was held. Byron Post Office (open since 1855) was replaced by the Inverell Post Office on 15 September 1859. The municipality was proclaimed in March 1872. The last section of
10584-529: Was an increasing emphasis on public-private partnerships to deliver infrastructure such as freeways, tunnels and rail links. The Carr government gained popularity for its successful organisation of international events, especially the 2000 Sydney Olympics, but Carr himself was critical of the federal government over its high immigration intake, arguing that a disproportionate number of new migrants were settling in Sydney, putting undue pressure on state infrastructure. Carr unexpectedly resigned from office in 2005 and
10692-424: Was elected in May 1941. The McKell government benefited from full employment, budget surpluses, and a co-operative relationship with John Curtin's federal Labor government. McKell became the first Labor leader to serve a full term and to be re-elected for a second. The Labor party was to govern New South Wales until 1965. The Labor government introduced two weeks of annual paid leave for most NSW workers in 1944, and
10800-485: Was formed in 1885 but New South Wales declined to join. A major obstacle to the federation of the Australian colonies was the protectionist policies of Victoria which conflicted with the free trade policies dominant in New South Wales. Nevertheless, the NSW premier Henry Parkes was a strong advocate of federation and his Tenterfield Oration in 1889 was pivotal in gathering support for the cause. Parkes also struck
10908-406: Was initially planned to be a self-sufficient penal colony based on subsistence agriculture. Trade and shipbuilding were banned to keep the convicts isolated. However, after the departure of Governor Phillip, the colony's military officers began acquiring land and importing consumer goods obtained from visiting ships. Former convicts also farmed land granted to them and engaged in trade. Farms spread to
11016-436: Was little recorded production up until approximately 1960, when commercial sapphire mining resumed due to a worldwide sapphire shortage. During the 1970s there were over 100 active mining operations in the New England region, however this number declined significantly in the 1980s due to weakening demand and exhaustion of the previously rich alluvial sources. Currently there are only a small number of commercially active mines in
11124-549: Was most likely the original source of tin. Other tin ores are less common sulfides such as stannite that require a more involved smelting process. Cassiterite often accumulates in alluvial channels as placer deposits because it is harder, heavier, and more chemically resistant than the accompanying granite . Cassiterite is usually black or dark in color, and these deposits can be easily seen in river banks . Alluvial ( placer ) deposits may incidentally have been collected and separated by methods similar to gold panning . In
11232-588: Was notable in that it was one of the very rare cases in colonial Australia for which white people were subsequently executed for the murder of Indigenous people. The crime became known as the Myall Creek Massacre . On 18 December 1838, seven men were publicly hanged at the Sydney Gaol for the atrocity. Every year on the Sunday of the June long weekend, hundreds of people, both Indigenous and non-Indigenous, gather at
11340-619: Was one of the factors leading the Trades and Labor Council to form a political party. The Labor Electoral League won a quarter of seats in the NSW elections of 1891 and held the balance of power between the Free Trade Party and the Protectionist Party . The suffragette movement was developing at this time. The Womanhood Suffrage League of New South Wales was founded in 1891. A Federal Council of Australasia
11448-402: Was possible to travel by train from Brisbane to Adelaide via Sydney and Melbourne. The extension of the rail network inland also encouraged regional industries and the development of the wheat belt . In the 1880s trade unions grew and were extended to lower skilled workers. In 1890 a strike in the shipping industry spread to wharves, railways, mines, and shearing sheds. The defeat of the strike
11556-620: Was replaced by Morris Iemma , who remained premier after being re-elected in the March 2007 state election , until he was replaced by Nathan Rees in September 2008. Rees was subsequently replaced by Kristina Keneally in December 2009, who became the first female premier of New South Wales. Keneally's government was defeated at the 2011 state election and Barry O'Farrell became Premier on 28 March. On 17 April 2014 O'Farrell stood down as Premier after misleading an ICAC investigation concerning
11664-415: Was used in solder. The rest was divided between tin plating, tin chemicals, brass and bronze alloys, and niche uses. Pigment Yellow 38, tin(IV) sulfide , is known as mosaic gold . Purple of Cassius , Pigment Red 109, a hydrous double stannate of gold , was mainly, in terms of painting, restricted to miniatures due to its high cost. It was widely used to make cranberry glass . It has also been used in
