Than platinum gained its value
The study of metals was quite common a few thousand years ago. Historians and archaeologists were trying to solve each detected "unidentified" piece. Along with other metals was found open and platinum. What kind of metal is known to mankind for about 4,000 years, but its value was not immediately appreciated. Opened the metal conquerors Colombia, which was mined gold from placer deposits, somewhere in the 16th century.
Precious metal miners often come across gold with small bits of unknown metal. Separate it from the gold do not get any, because this metal has a sufficiently high refractoriness, so this gold have called "rotten."
The name of the "platinum" the metal received from a certain similarity to silver, because the Spanish platina-it is a diminutive of the Spanish word plata - Silver. That is, if translated literally, it turns out that platinum is serebrishko. In order to preserve the value and prestige of Spanish coins were ordered to destroy all collected platinum, so for 43 years before witnesses officials discharged platinum into the depths of the river waters.
In addition, the melting point of platinum is sufficiently high, and also it has the huge density and thicker gold 2! In addition, platinum is not only the most durable of all metals and it is impossible to scratch, but it also has a very high anti-corrosion resistance and endures the influence of various chemicals. Qualities of platinum were evaluated only after the method has been found that the melting process and odd metal.
By the end of the 18th century, platinum stands for reliability, Permanence and is significantly affected its use in the manufacture of jewelry. This metal is valued much more than gold, because when it is used by jewelers with fastening stones, the foundation is much stronger and more reliable, and unlike gold has not yet set off some kind of metal.
In the Urals in 1821 near the river VerhnyayaNeyva were discovered placer platinum. Thus, in the early 19th century in Russia was approximately 95% of the world's metal. Already in 1828, began to produce platinum coins weighing 10 grams and 3 value in three rubles. Next, they were joined by 6 rubles coins, later -12. Another interesting thing is that they started to produce platinum, local hunters have used it as a fraction, completely unaware that shoot very expensive metal.
Found widespread use not only the platinum in jewelry, but also in industry and medicine. Through research it has also been discovered metal rhodium, iridium, palladium, ruthenium and osmium.
