MINNUNNATHELLAM PONNALLA ALL THAT GLITTERS IS NOT GOLD
GOLD PART 2(Continued from Part 1) 5 Monetary exchanges Gold is commonly formed into barsfor use in monetary exchange. Gold has been widely used throughout the world asa vehicle for monetary exchange, The first gold coins of the Grecian age were struck in Lydia around 700BC. The talent coin of gold in useduring the periods of Grecian history both before and during the time of thelife of Homer weighed between 8.42 and 8.75 grams. >From an earlier preference in using silver, European economiesre-established >the minting of gold as coinage during the thirteenth andfourteenth centuries However, production has not grownin relation to the world's economies. Today, gold mining output is declining. Fixed exchange rates of currenciesto gold were no longer sustained.At the beginning of World War I thewarring nations moved to a fractional gold standard, inflating their currenciesto finance the war effort. After World War II gold was replaced by a system of convertible currencyfollowing the Breton Woods system. Gold standards and the directconvertibility of currencies to gold have been abandoned by world governments,being replaced by fiat currency in their stead. Switzerland was the last countryto tie its currency to gold; it backed 40% of its value until the Swiss joinedthe International Monetary Fund in 1999. 5a. Earlier Gold coins of UK and US The gold content of alloys ismeasured in carats (k). Pure gold is designated as 24k. English gold coinsintended for circulation from 1526 into the 1930s were typically a standard 22k alloy called crown gold, for hardness. Americangold coins for circulation after 1837 contained the slightly lower amount of0.900 fine gold or 21.6 k. 6. Platinum and diamond Nowadays many jewellery advertisements give morepreference to Diamonds and Platinum than Gold. Itis understood they have gold and silver section, mostly silver section inbasement or top most floor in the shop!!! Although the prices of someplatinum group metals can be much higher, gold has long been considered themost desirable of precious metals, and its value has been used as the standardfor many currencies. Gold has been used as a symbol for purity, value, royalty,and particularly roles that combine these properties. 7. Thomas moor treatise Utopia When I read it in Wikipedia Icannot stop including it. I also imagined some thing similar may occur sometimes in near future. Gold as a sign of wealth and prestige was ridiculed by Thomas More in histreatise Utopia. On that imaginary island, gold is soabundant that it is used to make chains for slaves, tableware, and lavatoryseats. When ambassadors from othercountries arrive, dressed in ostentatious gold jewels and badges, the Utopiansmistake them for menial servants, paying homage instead to themost modestly dressed of their party. 8. Gold storage Many holders of gold store it inform of bullion coins or bars as a hedge against inflation or other economicdisruptions. Gold coinsare mostly 22 carat to put in nut shell. In recent years in India we getit in Banks, semi financial institutions and in Post offices also in additionto jewellery shops. Update- Now only in jewellery shops. 9. Gold jewellery Because of the softness of pure(24k) gold, it is usually alloyed with base metals for use in jewellery,altering its hardness and ductility, melting point, colour and otherproperties. Melting point is importantone to note among it. Alloys with lower caratage,typically 22k, 18k, 14k or 10k, contain higher percentages of copper or otherbase metals or silver or palladium in the alloy. Copper is the most commonly usedbase metal, yielding a redder colour. Now we may understand after remaking (notexchanging) and remaking some gold ornaments looked copper like? Fortunately today’s women are notfor remaking but for new purchase of ornaments giving back the old ones for FASHION CHANGE and not for damage (within a year mostly). They never bother of the financial losses. 10 Police Badges Eighteen-carat gold containing25% copper is found inantique and Russian jewellery and has a distinct, though not dominant, coppercast, creating rose gold. Fourteen-carat gold-copper alloy is nearly identical in colour tocertain bronze alloys, and both may be used to produce police and otherbadges. 11. Blue gold and Purple gold Blue gold can be made by alloyingwith IRON and purple gold can be made by alloying with ALUMINIUM, although rarely done except inspecialize jewellery. Blue gold is more brittle and therefore more difficult towork with when making jewellery. 12 Green gold and white gold Fourteen- and eighteen-carat gold alloys with silver alone appeargreenish-yellow and are referred to as green gold. White gold alloys can be made withpalladium, silver and other white metals. The palladium alloys are more expensive than those using nickel. High-caratwhite gold alloys are far more resistant to corrosion than are either puresilver or sterling silver. The Japanese craft of Mokume-ganeexploits the colour contrasts between laminated coloured gold alloys to producedecorative wood-grain effects. My note- So with a mixing of goldnon corrosive white pancha pathram uddirini can be made. Shining PANCHA PATHRAM UDDIRINI. If price decline for gold we may make such in the near future. 13. Medicinal effects In medieval times, gold was often seen as beneficial for the health, in thebelief that something so rare and beautiful could not be anything but healthy. Some gold salts do haveanti-inflammatory properties and are used as pharmaceuticals in the treatmentof arthritis and other similar conditions. Gold based injections havebeen explored as a means to help to reduce the pain and swelling of rheumatoidarthritis and tuberculosis.However, only salts andradioisotopes of gold are of pharmacological value, as elemental (metallic)gold is inert to all chemicals it encounters inside the body. 14 Swarnappal (Gold tooth) Gold alloys are used inrestorative dentistry, especially in tooth restorations, such as crowns andpermanent bridges. The gold alloys' slight malleability facilitatesthe creation of a superior molar mating surface with other teeth and producesresults that are generally more satisfactory than those produced by thecreation of porcelain crowns. After root canal treatment crownsare suggested by dental surgeons in various rates. The yellowish ones maycontain gold. However these are priced VERY HIGH. Recent quoteby dentist for single ceramic cap was 3400-00 in addition to root canal charges My note- At one time silver filling was there for cavity after cleaning. But now either removal or rootcanal. 15. Gold in food Metallic gold is inert to all bodychemistry, it has no taste, it provides no nutrition, and it leaves the bodyunaltered. I read paragraphs about Goldleaf, Gold flakes and gold dust. But due to the above there is no purpose of adding it since it is notgoing to serve any purpose.
