Cornish became extinct as a living community language in Cornwall by the end of the 18th century , although knowledge of Cornish, including speaking ability to a certain extent, persisted within some families and individuals. A revival started in

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

6080-528: 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

The revival focused on reconstructing and standardising
10488-829: The Cornish language ceased, and responsibility transferred to Cornwall Council. Until around the middle of the 11th century, Old Cornish scribes used a traditional spelling system shared with Old Breton and Old Welsh, based on the pronunciation of British Latin . By the time of the Vocabularium Cornicum , usually dated to around 1100, Old English spelling conventions, such as the use of thorn (Þ, þ) and eth (Ð, ð) for dental fricatives , and wynn (Ƿ, ƿ) for /w/, had come into use, allowing documents written at this time to be distinguished from Old Welsh, which rarely uses these characters, and Old Breton, which does not use them at all. Old Cornish features include using initial ⟨ch⟩, ⟨c⟩, or ⟨k⟩ for /k/, and, in internal and final position, ⟨p⟩, ⟨t⟩, ⟨c⟩, ⟨b⟩, ⟨d⟩, and ⟨g⟩ are generally used for
10640-469: The Cornish language comes from this period: a 9th-century gloss in a Latin manuscript of De Consolatione Philosophiae by Boethius , which used the words ud rocashaas . The phrase may mean "it [the mind] hated the gloomy places", or alternatively, as Andrew Breeze suggests, "she hated the land". Other sources from this period include the Saints' List , a list of almost fifty Cornish saints,
10792-438: The Cornish orthography within them. Around 1700, Edward Lhuyd visited Cornwall, introducing his own partly phonetic orthography that he used in his Archaeologia Britannica , which was adopted by some local writers, leading to the use of some Lhuydian features such as the use of circumflexes to denote long vowels, ⟨k⟩ before front vowels, word-final ⟨i⟩, and the use of ⟨dh⟩ to represent the voiced dental fricative /ð/. After
10944-513: The Cornishmen should be offended by holding the service in English, when they had before held it in Latin , which even fewer of them could understand. Anthony Fletcher points out that this rebellion was primarily motivated by religious and economic, rather than linguistic, concerns. The rebellion prompted a heavy-handed response from the government, and 5,500 people died during the fighting and
11096-596: The Grand Jury regarding the tumult. The entire Camborne police force was found to be at fault and either removed from duty or transferred as a result. No rioter was ever convicted. Dolcoath Mine , (English: Old Ground Mine ), the 'Queen of Cornish Mines' was, at a depth of 3,500 feet (1,067 m), for many years the deepest mine in the world, not to mention one of the oldest before its closure in 1921. The last working tin mine in Europe, South Crofty , which closed in 1998,
11248-560: The Middle Cornish ( Kernewek Kres ) period (1200–1600), reaching a peak of about 39,000 speakers in the 13th century, after which the number started to decline. This period provided the bulk of traditional Cornish literature , and was used to reconstruct the language during its revival. Most important is the Ordinalia , a cycle of three mystery plays, Origo Mundi , Passio Christi and Resurrexio Domini . Together these provide about 8,734 lines of text. The three plays exhibit
11400-464: The Near East where arsenic is commonly found with copper ore, but the health risks were quickly realized and the quest for sources of the much less hazardous tin ores began early in the Bronze Age. This created the demand for rare tin metal and formed a trade network that linked the distant sources of tin to the markets of Bronze Age cultures. Cassiterite ( SnO 2 ), the oxide form of tin,
11552-654: The United States has neither mined (since 1993) nor smelted (since 1989) tin, it was the largest secondary producer, recycling nearly 14,000 tonnes in 2006. New deposits are reported in Mongolia , and in 2009, new deposits of tin were discovered in Colombia. Tin is produced by carbothermic reduction of the oxide ore with carbon or coke. Both reverberatory furnace and electric furnace can be used: The ten largest tin-producing companies produced most of
11704-496: 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
11856-401: The agricultural land on the other side. Camborne has an oceanic climate typical of Cornwall with particularly narrow temperature ranges even by British standards . The absence of a large landmass nearby means that warm air from the continent gets cooled down over the sea in summer. In winter, cold air masses get moderated by the same effect. Rainfall is frequent all year due to moist air from
12008-479: The authorities came to associate it with sedition and "backwardness". This proved to be one of the reasons why the Book of Common Prayer was never translated into Cornish (unlike Welsh ), as proposals to do so were suppressed in the rebellion's aftermath. The failure to translate the Book of Common Prayer into Cornish led to the language's rapid decline during the 16th and 17th centuries. Peter Berresford Ellis cites
12160-409: The base for a sundial in the grounds of Pendarves House. Camborne churchyard contains a number of crosses collected from nearby sites: the finest is one found in a well at Crane in 1896 but already known from William Borlase 's account of it when it was at Fenton-ear. Arthur Langdon (1896) records six crosses in the parish, including two at Pendarves , two at Trevu and one outside the institute. There
12312-409: The basis of revived Cornish ( Kernewek Dasserghys ) for most of the 20th century. During the 1970s, criticism of Nance's system, including the inconsistent orthography and unpredictable correspondence between spelling and pronunciation, as well as on other grounds such as the archaic basis of Unified and a lack of emphasis on the spoken language, resulted in the creation of several rival systems. In
12464-483: The beginning of the Celtic Revival in the late 19th century, provided the groundwork for a Cornish language revival movement. Notwithstanding the uncertainty over who was the last speaker of Cornish, researchers have posited the following numbers for the prevalence of the language between 1050 and 1800. In 1904, the Celtic language scholar and Cornish cultural activist Henry Jenner published A Handbook of
12616-617: The body, including lof 'hand' and dans 'tooth'. Inherited adjectives with an Indo-European etymology include newyth 'new', ledan 'broad, wide', rud 'red', hen 'old', iouenc 'young', and byw 'alive, living'. Several Celtic or Brittonic words cannot be reconstructed to Proto-Indo-European, and are suggested to have been borrowed from unknown substrate language(s) at an early stage, such as Proto-Celtic or Proto-Brittonic. Proposed examples in Cornish include coruf 'beer' and broch 'badger'. Other words in Cornish inherited direct from Proto-Celtic include
12768-604: The complex agreements between producer countries and consumer countries dating back to 1921. Earlier agreements tended to be somewhat informal and led to the "First International Tin Agreement" in 1956, the first of a series that effectively collapsed in 1985. Through these agreements, the International Tin Council (ITC) had a considerable effect on tin prices. ITC supported the price of tin during periods of low prices by buying tin for its buffer stockpile and
12920-557: The creation of Unified Cornish Revised, a modified version of Nance's orthography, featuring: an additional phoneme not distinguished by Nance, "ö in German schön ", represented in the UCR orthography by ⟨ue⟩; replacement of ⟨y⟩ with ⟨e⟩ in many words; internal ⟨h⟩ rather than ⟨gh⟩; and use of final ⟨b⟩, ⟨g⟩, and ⟨dh⟩ in stressed monosyllables. A Standard Written Form , intended as a compromise orthography for official and educational purposes,
13072-560: The culture of Cornwall. Examples include atal 'mine waste' and beetia 'to mend fishing nets'. Foogan and hogan are different types of pastries. Troyl is a 'traditional Cornish dance get-together' and Furry is a specific kind of ceremonial dance that takes place in Cornwall. Certain Cornish words may have several translation equivalents in English, so for instance lyver may be translated into English as either 'book' or 'volume' and dorn can mean either 'hand' or 'fist'. As in other Celtic languages, Cornish lacks
13224-527: The defeat of the Britons at the Battle of Deorham in about 577. The western dialects eventually evolved into modern Welsh and the now extinct Cumbric , while Southwestern Brittonic developed into Cornish and Breton, the latter as a result of emigration to parts of the continent, known as Brittany over the following centuries. The area controlled by the southwestern Britons was progressively reduced by
13376-504: The dental fricatives /θ/ and /ð/, a usage which is unique to Middle Cornish and is never found in Middle English. Middle Cornish scribes tend to use ⟨c⟩ for /k/ before back vowels, and ⟨k⟩ for /k/ before front vowels, though this is not always true, and this rule is less consistent in certain texts. Middle Cornish scribes almost universally use ⟨wh⟩ to represent /ʍ/ (or /hw/), as in Middle English. Middle Cornish, especially towards
13528-400: The early 20th century, and in 2010 UNESCO reclassified the language as critically endangered , stating that its former classification of the language as extinct was no longer accurate. The language has a growing number of second-language speakers, and a very small number of families now raise children to speak revived Cornish as a first language . Cornish is currently recognised under
13680-431: The end of this period, tends to use orthographic ⟨g⟩ and ⟨b⟩ in word-final position in stressed monosyllables, and ⟨k⟩ and ⟨p⟩ in word-final position in unstressed final syllables, to represent the reflexes of late Brittonic /ɡ/ and /b/, respectively. Written sources from this period are often spelled following English spelling conventions since many of the writers of the time had not been exposed to Middle Cornish texts or
13832-436: The evidence of this rhyme, of what there was to lose by neglecting John Davey." The search for the last speaker is hampered by a lack of transcriptions or audio recordings, so that it is impossible to tell from this distance whether the language these people were reported to be speaking was Cornish, or English with a heavy Cornish substratum , nor what their level of fluency was. Nevertheless, this academic interest, along with
13984-475: The existence of multiple orthographies was unsustainable with regards to using the language in education and public life, as none had achieved a wide consensus. A process of unification was set about which resulted in the creation of the public-body Cornish Language Partnership in 2005 and agreement on a Standard Written Form in 2008. In 2010 a new milestone was reached when UNESCO altered its classification of Cornish, stating that its previous label of "extinct"
14136-605: The expansion of Wessex over the next few centuries. During the Old Cornish ( Kernewek Koth ) period (800–1200), the Cornish-speaking area was largely coterminous with modern-day Cornwall , after the Saxons had taken over Devon in their south-westward advance, which probably was facilitated by a second migration wave to Brittany that resulted in the partial depopulation of Devon. The earliest written record of
14288-460: The family, names for various kinds of artisans and their tools, flora, fauna, and household items. The manuscript was widely thought to be in Old Welsh until the 18th century when it was identified as Cornish by Edward Lhuyd . Some Brittonic glosses in the 9th-century colloquy De raris fabulis were once identified as Old Cornish, but they are more likely Old Welsh, possibly influenced by
14440-835: The field adjoining the Pendarves Arms Inn at Beacon, the Unicorn Inn, the White Hart Inn and the recreation ground. There were various local cups that were competed for including the "Mrs Bramble Cup", the "Allen Cup" and the "Moreing Cup". Sam Ham (1880–1946), was born in Condurrow near Camborne, was the 1910 middleweight Cornish wrestling champion of South Africa. See Cornish wrestling in Roskear and Cornish wrestling in Pool A Church of England National School
14592-591: The fourth century —the earlier Latin word for it was plumbum candidum , or "white lead". Stannum apparently came from an earlier stāgnum (meaning the same substance), the origin of the Romance and Celtic terms for tin , such as French étain , Spanish estaño , Italian stagno , and Irish stán . The origin of stannum / stāgnum is unknown; it may be pre- Indo-European . The Meyers Konversations-Lexikon suggests instead that stannum came from Cornish stean , and
14744-439: The great majority of its compounds, tin has the oxidation state II or IV. Compounds containing bivalent tin are called stannous while those containing tetravalent tin are termed stannic . Halide compounds are known for both oxidation states. For Sn(IV), all four halides are well known: SnF 4 , SnCl 4 , SnBr 4 , and SnI 4 . The three heavier members are volatile molecular compounds, whereas
14896-643: The greatest shows of mining defiance in Cornish history left the Town Hall vandalised, the Police Station ransacked, and the estimated fifty constables present in the town beaten and scattered. The militia were called in from Plymouth to quell the insurrection, and the Home Secretary, Robert Lowe , asked to be kept informed of events. The Camborne riots were reported in the national newspapers and Sir Colman Rashleigh , JP for Cornwall, had to address
15048-400: The individualised nature of language take-up. Nevertheless, there is recognition that the number of Cornish speakers is growing. From before the 1980s to the end of the 20th century there was a sixfold increase in the number of speakers to around 300. One figure for the number of people who know a few basic words, such as knowing that "Kernow" means "Cornwall", was 300,000; the same survey gave
15200-402: The inhabitants can speak no word of Cornish, but very few are ignorant of the English; and yet some so affect their own, as to a stranger they will not speak it; for if meeting them by chance, you inquire the way, or any such matter, your answer shall be, " Meea navidna caw zasawzneck ," "I [will] speak no Saxonage." The Late Cornish ( Kernewek Diwedhes ) period from 1600 to about 1800 has
15352-957: The language are the initial consonant mutations , the verb–subject–object word order, inflected prepositions , fronting of emphasised syntactic elements and the use of two different forms for 'to be'. Cornish has initial consonant mutation : The first sound of a Cornish word may change according to grammatical context. As in Breton, there are four types of mutation in Cornish (compared with three in Welsh , two in Irish and Manx and one in Scottish Gaelic ). These changes apply to only certain letters (sounds) in particular grammatical contexts, some of which are given below: Cornish has no indefinite article . Porth can either mean 'harbour' or 'a harbour'. In certain contexts, unn can be used, with
15504-407: The language despite not being fluent nor using the language in daily life, generally survive even longer. The traditional view that Dolly Pentreath (1692–1777) was the last native speaker of Cornish has been challenged, and in the 18th and 19th centuries there was academic interest in the language and in attempting to find the last speaker of Cornish. It has been suggested that, whereas Pentreath
15656-602: The language is taught in schools and appears on street nameplates. The first Cornish-language day care opened in 2010. Cornish is a Southwestern Brittonic language, a branch of the Insular Celtic section of the Celtic language family , which is a sub-family of the Indo-European language family. Brittonic also includes Welsh , Breton , Cumbric and possibly Pictish , the last two of which are extinct . Scottish Gaelic , Irish and Manx are part of
15808-580: The language regularly, with 5,000 people having a basic conversational ability in the language. A report on the 2011 Census published in 2013 by the Office for National Statistics placed the number of speakers at somewhere between 325 and 625. In 2017 the ONS released data based on the 2011 Census that placed the number of speakers at 557 people in England and Wales who declared Cornish to be their main language, 464 of whom lived in Cornwall. The 2021 census listed
15960-438: The language, including coining new words for modern concepts, and creating educational material in order to teach Cornish to others. In 1929 Robert Morton Nance published his Unified Cornish ( Kernewek Unys ) system, based on the Middle Cornish literature while extending the attested vocabulary with neologisms and forms based on Celtic roots also found in Breton and Welsh, publishing a dictionary in 1938. Nance's work became
16112-411: The largest number of stable isotopes in the periodic table, due to its magic number of protons. It has two main allotropes : at room temperature, the stable allotrope is β-tin, a silvery-white, malleable metal; at low temperatures it is less dense grey α-tin, which has the diamond cubic structure. Metallic tin does not easily oxidize in air and water. The first tin alloy used on a large scale
16264-507: The largest urban and industrial area in Cornwall with the town of Redruth three miles (five kilometres) east. It is the ecclesiastical centre of a large civil parish and has a town council . Camborne-Redruth is on the northern side of the Carn Brea / Carnmenellis granite upland which slopes northwards to the sea. The two towns are linked by the A3047 road which was turnpiked in 1839 and
16416-451: The late 1970s and early 1980s, the U.S. reduced its strategic tin stockpile, partly to take advantage of historically high tin prices. The 1981–82 recession damaged the tin industry. Tin consumption declined dramatically. ITC was able to avoid truly steep declines through accelerated buying for its buffer stockpile; this activity required extensive borrowing. ITC continued to borrow until late 1985 when it reached its credit limit. Immediately,
16568-455: The market and mining technology. It is estimated that, at current consumption rates and technologies, the Earth will run out of mine-able tin in 40 years. In 2006 Lester Brown suggested tin could run out within 20 years based on conservative estimates of 2% annual growth. Scrap tin is an important source of the metal. Recovery of tin through recycling is increasing rapidly as of 2019. Whereas
16720-436: The meaning 'a certain, a particular', e.g. unn porth 'a certain harbour'. There is, however, a definite article an 'the', which is used for all nouns regardless of their gender or number, e.g. an porth 'the harbour'. Cornish nouns belong to one of two grammatical genders , masculine and feminine, but are not inflected for case . Nouns may be singular or plural. Plurals can be formed in various ways, depending on
16872-412: The most stable being tin-121m, with a half-life of 43.9 years. The relative differences in the abundances of tin's stable isotopes can be explained by how they are formed during stellar nucleosynthesis . Tin-116 through tin-120, along with tin-122, are formed in the s -process (slow neutron capture) in most stars which leads to them being the most common tin isotopes, while tin-124 is only formed in
17024-458: The noun: Tin Tin is a chemical element ; it has symbol Sn (from Latin stannum ) and atomic number 50. A silvery-colored metal, tin is soft enough to be cut with little force, and a bar of tin can be bent by hand with little effort. When bent, the so-called " tin cry " can be heard as a result of twinning in tin crystals. Tin is a post-transition metal in group 14 of
17176-565: The number of Cornish speakers at 563. A study that appeared in 2018 established the number of people in Cornwall with at least minimal skills in Cornish, such as the use of some words and phrases, to be more than 3,000, including around 500 estimated to be fluent. The Institute of Cornish Studies at the University of Exeter is working with the Cornish Language Partnership to study the Cornish language revival of
17328-410: The number of people able to have simple conversations as 3,000. The Cornish Language Strategy project commissioned research to provide quantitative and qualitative evidence for the number of Cornish speakers: due to the success of the revival project it was estimated that 2,000 people were fluent (surveyed in spring 2008), an increase from the estimated 300 people who spoke Cornish fluently suggested in
17480-415: The orthography and rhyme used in the historical texts, comparison with the other Brittonic languages Breton and Welsh, and the work of the linguist Edward Lhuyd , who visited Cornwall in 1700 and recorded the language in a partly phonetic orthography. Cornish is a Celtic language, and the majority of its vocabulary, when usage frequency is taken into account, at every documented stage of its history
17632-835: The other Brittonic languages. The first sound change to distinguish Cornish from both Breton and Welsh, the assibilation of the dental stops /t/ and /d/ in medial and final position, had begun by the time of the Vocabularium Cornicum , c. 1100 or earlier. This change, and the subsequent, or perhaps dialectical, palatalization (or occasional rhotacization in a few words) of these sounds, results in orthographic forms such as Middle Cornish tas 'father', Late Cornish tâz (Welsh tad ), Middle Cornish cresy 'believe', Late Cornish cregy (Welsh credu ), and Middle Cornish gasa 'leave', Late Cornish gara (Welsh gadael ). A further characteristic sound change, pre-occlusion , occurred during
17784-413: The phonemes /b/, /d/, /ɡ/, /β/, /ð/, and /ɣ/ respectively, meaning that the results of Brittonic lenition are not usually apparent from the orthography at this time. Middle Cornish orthography has a significant level of variation, and shows influence from Middle English spelling practices. Yogh (Ȝ ȝ) is used in certain Middle Cornish texts, where it is used to represent a variety of sounds, including
17936-604: The pioneering Celtic linguist Edward Lhuyd came to Cornwall to study the language and visited Camborne, detailing many aspects of the parish. One of the most important surviving works of medieval Cornish literature is Beunans Meriasek , the Life of St Meriadoc the patron saint of Camborne. In the 19th century the nickname for Camborne people was Mera-jacks, or Merry-geeks, and those who washed in St Meriasek's well were called Merrasicks, Merrasickers, Moragicks or Mearagaks. In
18088-462: The post- Second World War period. By 1984 Cornish was being taught in Troon and Camborne primary schools as well as Camborne secondary school and there was a Cornish language playgroup. In 2000 Roskear and Weeth schools were teaching Cornish. In the 2011 United Kingdom census , although there was no specific Cornish language question, thirty people living in the parish of Camborne declared that Cornish
18240-613: 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
18392-447: The publication of Jenner's Handbook of the Cornish Language , the earliest revivalists used Jenner's orthography, which was influenced by Lhuyd's system. This system was abandoned following the development by Nance of a "unified spelling", later known as Unified Cornish , a system based on a standardization of the orthography of the early Middle Cornish texts. Nance's system was used by almost all Revived Cornish speakers and writers until
18544-472: 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
18696-473: The rebellion's aftermath. Government officials then directed troops under the command of Sir Anthony Kingston to carry out pacification operations throughout the West Country. Kingston subsequently ordered the executions of numerous individuals suspected of involvement with the rebellion as part of the post-rebellion reprisals. The rebellion eventually proved a turning-point for the Cornish language, as
18848-508: The reign of Henry VIII, an account was given by Andrew Boorde in his 1542 Boke of the Introduction of Knowledge . He states, " In Cornwall is two speches, the one is naughty Englysshe, and the other is Cornysshe speche. And there be many men and women the which cannot speake one worde of Englysshe, but all Cornyshe. " When Parliament passed the Act of Uniformity 1549 , which established
19000-456: 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
19152-415: 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
19304-465: The separate Goidelic branch of Insular Celtic. Joseph Loth viewed Cornish and Breton as being two dialects of the same language, claiming that "Middle Cornish is without doubt closer to Breton as a whole than the modern Breton dialect of Quiberon [ Kiberen ] is to that of Saint-Pol-de-Léon [ Kastell-Paol ]." Also, Kenneth Jackson argued that it is almost certain that Cornish and Breton would have been mutually intelligible as long as Cornish
19456-586: 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
19608-678: 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
19760-420: 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
19912-523: 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
20064-588: 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
20216-467: The town has become the A3047. The railway station is a half-mile south from the town centre, with a level crossing and footbridge at its eastern end. Camborne railway station used to be famous for its short platforms, which meant that passengers on main line services between London Paddington and Penzance could only board and alight from certain carriages. Partly because of this not all services stopped at Camborne, preferring nearby Redruth (which
20368-518: The villages along the road (from the west) were Roskear, Tuckingmill, Pool and Illogan. Running north-south are a number of small streams with narrow river valleys which have been deeply-cut following centuries of tin streaming and other industrial processes. An example is the Red River valley which crosses the A3047 at Tuckingmill. To the north, the A30 (road) forms a boundary between the urban area and
20520-606: 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
20672-537: The years 1550–1650 as a century of immense damage for the language, and its decline can be traced to this period. In 1680 William Scawen wrote an essay describing 16 reasons for the decline of Cornish, among them the lack of a distinctive Cornish alphabet , the loss of contact between Cornwall and Brittany , the cessation of the miracle plays, loss of records in the Civil War, lack of a Cornish Bible and immigration to Cornwall. Mark Stoyle , however, has argued that
20824-473: 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
20976-564: Was a living language, and that Cornish and Breton are especially closely related to each other and less closely related to Welsh. Cornish evolved from the Common Brittonic spoken throughout Britain south of the Firth of Forth during the British Iron Age and Roman period . As a result of westward Anglo-Saxon expansion , the Britons of the southwest were separated from those in modern-day Wales and Cumbria , which Jackson links to
21128-458: 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
21280-683: Was built in College Street in 1844 (replaced by a newer building further up the street towards the parish church in 1896-now demolished); in the following year a school for four hundred boys was opened in the Centenary Methodist Chapel and in 1847 the Basset Road British (Methodist) School was opened. A School of Mines started in 1872 with the Basset family paying for chemistry laboratories. The town now has
21432-421: Was completed in 1866. Mining is first recorded locally in the 1400s with early exploitation of the small streams cutting through the mineralised area and from shallow mines following lodes. Adit mining was first recorded in the 16th century. The town is best known as a centre for the former Cornish tin and copper mining industry, having its working heyday during the later 18th and early 19th centuries. Camborne
21584-480: Was established in 1851. Plans for the school were laid out in 1829, leading to the current school in 1888. It now forms part of the University of Exeter ; it moved to the university's Tremough campus (now known as Penryn Campus ) in 2004. On Christmas Eve 1801, the Puffing Devil – a steam-powered road locomotive built by Camborne engineer Richard Trevithick – made its way up Camborne Hill in Cornwall. It
21736-708: Was introduced in 2008, although a number of previous orthographic systems remain in use and, in response to the publication of the SWF, another new orthography, Kernowek Standard , was created, mainly by Nicholas Williams and Michael Everson, which is proposed as an amended version of the Standard Written Form. The phonological system of Old Cornish, inherited from Proto-Southwestern Brittonic and originally differing little from Old Breton and Old Welsh, underwent various changes during its Middle and Late phases, eventually resulting in several characteristics not found in
21888-439: Was just a village until transformed by the mining boom which began in the late 18th century and saw the Camborne and Redruth district become the "richest square mile in the old world". As the economic recession of the 1870s led to the first years of mining decline in Camborne, social tensions mounted. In October 1873 thousands of miners, aided and abetted by the townspeople, rioted against a hated, authoritarian police force. One of
22040-549: 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
22192-417: Was no longer accurate. Speakers of Cornish reside primarily in Cornwall , which has a population of 563,600 (2017 estimate). There are also some speakers living outside Cornwall, particularly in the countries of the Cornish diaspora , as well as in other Celtic nations . Estimates of the number of Cornish speakers vary according to the definition of a speaker, and is difficult to determine accurately due to
22344-512: Was opened in November 1902 and ran a regular service to Redruth until it closed in September 1927. Camborne RFC were established in 1878 and are one of the most famous clubs in Cornwall, having produced numerous Cornwall players over the years. In 1987 Camborne were the highest placed Cornish club in the newly formed National leagues when they entered at 1987–88 Courage Area League South (equivalent to National League 2 South today). Camborne
22496-567: Was probably the last monolingual speaker, the last native speaker may have been John Davey of Zennor, who died in 1891. However, although it is clear Davey possessed some traditional knowledge in addition to having read books on Cornish, accounts differ of his competence in the language. Some contemporaries stated he was able to converse on certain topics in Cornish whereas others affirmed they had never heard him claim to be able to do so. Robert Morton Nance , who reworked and translated Davey's Cranken Rhyme, remarked, "There can be no doubt, after
22648-403: Was probably the last prose written in the traditional language. In his letter, he describes the sociolinguistics of the Cornish language at the time, stating that there are no more than four or five old people in his village who can still speak Cornish, concluding with the remark that Cornish is no longer known by young people. However, the last recorded traditional Cornish literature may have been
22800-401: Was the world's first self-propelled passenger carrying vehicle. The events have been turned into a local song: The Cornish language was the language of the area around Camborne until the beginning of the 18th century and it is recorded that everyone living west of Truro spoke Cornish in 1644. Nicholas Boson wrote that Cornish was spoken as far east as Redruth and Falmouth circa 1700. In 1700
22952-473: Was their main language at home, thirteen in Troon and Beacon. The Camborne and Redruth constituency was created for the 2010 general election , following a review of parliamentary representation in Cornwall by the Boundary Commission for England , which increased the number of seats in the county from five to six. It is primarily a successor to the former Falmouth and Camborne seat. In
23104-415: 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
