The olympic games, the most recent of which was held in tokyo, were of global interest, and the olympic gold medals were the goal of every player. Are the tokyo olympic gold medals, compiled by a graduate student abroad, pure gold? For your information only。
Is the tokyo olympic gold medal pure gold
Nope. Each gold medal at the tokyo olympic games consists of 550 grams of silver and 6 grams of gold plating, which, in terms of the price of materials alone, currently amounts to approximately 5,000 yuan。
The silver plate is 550 grams of pure silver and is currently worth approximately 3,000 yuan。
The copper plate weighs about 450 grams, with 95 per cent of copper and 5 per cent of zinc, and is currently approximately 30 yuan。
It is worth mentioning that all medals of the olympic games are made of recycled electronic waste. This is the first time in olympic history。
In 2017, the government of japan initiated the recycling of household electricity from used mobile phones. Over a period of more than two years, nearly 79,000 tons of small household electricity and 6. 21 million old mobile phones were collected from the country, from which about 32 kilograms of pure gold, 3,500 kilograms of pure silver and 2,200 kilograms of copper were extracted, and all tokyo olympic medals were finally made out of these recycled metals。
The biggest medal ever
Most expensive: sweden
The 5th summer olympic games in 1912 were held in stockholm, the capital of sweden, with 28 countries and regions invited to the games, and with the exception of the four continents of europe, the united states, africa and australia, for the first time, japan in asia sent two players to the games, thus making a real gathering of athletes from the five continents of the world at the official olympics。
The winner of this medal is a picture of two women wearing a lunar garland ring for a young olympic champion, and a picture of the announcement of the olympic games by the press officer on the back of the medal. Of particular note is the fact that the gold medal at the stockholm olympics in 1912 was pure gold, which became the “single” in the history of the olympics, and that most of the gold medals since then were made of silver and gold。
The olympic games in stockholm are rich and valuable, while two olympic games in olympic history do not have gold medals: the winner of the first modern olympic games, held in athens, greece, in 1896, was a silver medal, an olive wreath and a medal; at the second modern olympic games, held in paris, france, in 1900, the first three medals, without distinction as to gold, silver or copper, were a rectangular medal. Of course, they all have profound commemorative significance。
Most unique: china
The medal is 70 mm in diameter, 6 mm thick, and the medal's face is a unified ioc pattern. – the victory goddess of greece and the greek pannasinako arena, with the medals on its back embedded in the jade made from china’s ancient dragon-striped jade, and the metal on its back with the beijing olympic emblem on its face。
The medals of the 2008 beijing olympic games have broken the tradition of designing single materials for any of the previous olympic medals, using a gold-smalled style that depicts the “goldness of gold” in china's traditional culture。
The medals are 70 mm in diameter, 6 mm thick, and they have a uniform formula for the ioc. – the victory goddess of greece and the greek pannasinako arena, with the medals on its back embedded in the jade made from china’s ancient dragon-striped jade, and the metal on its back with the beijing olympic emblem on its face。
Generally, olympic medals weigh about 500 grams. The golden card of the panchang winter olympics in 2018 was 586 grams, the most heavy gold in olympic history, but its gold content was 6 grams below the limit set by ioc and the remaining 580 grams were pure silver. The lightest gold medal in history is the 2008 beijing olympic medal, weighing 200 grams
But the cost is not low, especially since the design concept of “golden jade” is of great significance, reflecting both a tribute to the winners and an image that interprets the values of the chinese people since ancient times, the chinese civilization and the olympic spirit in the context of the beijing olympics。
In addition to the medal itself, the beijing olympic medal wrapping box is also very dedicated to wood paint boxes for traditional chinese crafts. The shape of the quartet, the quartet, and the quartet, are a little arc of the quartet。
Most embarrassing: rio
The 31st summer olympic games were held in rio de janeiro, brazil, in 2016, and rio became the first south american city to host the summer olympics. It was also the first summer olympic games organized by portuguese-speaking countries and the first exclusively during the winter period of the host countries。
But there's a small episode of this south american olympic games, nine months after its closure, when a mess came to us — hundreds of olympic medals were rusty
