Chervonny gold is not a pure metal, but is an alloy with the addition of copper. He is owned by a refined reddish tint. The term "Chervonny" has long been not applied to gold in a modern classification. Now it can be heard only in conversational speech.
What is it and when it appeared?
Alloy Now is a big rarity and actually does not apply Since it is impractical and uncomfortable for everyday use. Get the jewelry from the alloy of Chervonny Gold will succeed, only by ordering its production from the jeweler individually.
It is unofficially called "Russian", but in Russia, a small demand for decorations from this metal. Chervonne is called an alloy with pure gold. It should have up to 10% of additives and at least 90% of the precious metal.
Since this material demonstrates high softness, traditionally mix additives in the form of iridium, cadmium, as well as platinum, silver, zinc, copper and others. Such impurities are called ligature. . With them, the properties of gold are enhanced, including its strength increases. Additives affect the color of precious material.
Chervoy or, as they say, shoved in the translation from Staroslavlyansky - it means scarlet, red. In Tsarist Russia, there were foreign coins of gold, which were called Chervonians. Companing its own coins in Russia began only from the XV century in the form of premium distinctive signs.
The appearance of the first Russian Chervonians as a payment agent was due Monetary reform conducted by Peter Great. Their weight and value of the alloy corresponded to overseas coins. Chervonians were calculated with foreign subjects.
Also, they began to produce expensive jewelry, because then there were no cleaner gold than Chervonne.
Presumably to get a reddish subton in ancient In gold mixed the paint from the extract of a special kind of worms. According to another version, the term has occurred from the long-out of the word "shreddy" , meaning "dark red" color. There is a third option in which The word "Chervoy" is interpreted as "hot" . When heated, the alloy appeared "Chervoy" gleam. With a large number of additives, the red color did not show.
Last time, the amount of gold in products was measured spools (4,266 g) , and K. Chervonne applied all since 72-spools . Historically, his sample was considered high (not lower than this 750). Sometimes and now the red valuable metal is mistakenly called "Chervonny": in red gold, the percentage of copper is significantly higher - 41.5, which corresponds to a sample labeling 585.
The decorations created from the Chervon Gold were considered impractical, and they were made only by the jewelers of famous homes.
Mostly it was special Family jewels , reverently stored and transmitted from generation to generation. The exceptions were things in which fragility and softness compensated for weight. Most often, those who encountered "shred" products weigh from 10 grams.
In modern days, under the term "Chervoy" understand not only the shade of gold, but also directly the royal worm. In Soviet times, made of such coins were made Dental crowns . Such a solution in the medical sense was not bad: pure and soft noble metal with large inertia, not reacting to acid and alkali, that is, safe for health.
A shade with "Krasninka" should look barely noticeable , visible only in comparison with the product, for example, labeling 585 samples. Unfortunately, at present, the term "Chervonny Gold" is made to designate a cheap alloy with gold, distinct red due to excessive content in it. True noble gold exhibits its famous reddish shade only when heated.
Properties
The percentage of copper may vary, but The amount of gold always exceeds 90% So, this is a valuable high-period variety. Characteristics of the Chervonny Alloy differ from pure gold Drigate, smooth, excessive soft. It is so inclined to deformation and abrasion that its authenticity was determined by primitive supervision test - on the present alloy, traces of teeth were clearly manifested.
Sample
Absolute 100% gold in nature , famous fact. There is only a highly specifically called "clean". It is impractical and easily deformed material. It is suitable for the production of exclusively banking ingots.
But will it be correct to calculate them to the category of Chervonny Gold? There is no single opinion on this. Jewelers refer to a Chervon Money Alloy In the range of samples from 916 and to 986th. but In different publications the so-called metal of juicy yellow color, going on ingots : 995th, 999th and 999.9-sample, that is, when 99.99% is a noble metal, and the rest is impurities.
It turns out around the "Russian" gold a lot of confusion. In any case, we are talking about the alloys of the highest sample . Concerning Popular Chervonny Alloys, That, besides the main component, they contain the shares of silver and red copper.
By purchasing such decorations, you need to exercise special vigilance. Scammers add copper into a metal of a low sample, seeking a famous reddish shade. Which should not affect the values and cost of the product. When buying is not only possible, but also need Ask a qualitative certificate from the consultant Products. If the thing is purchased in private, it is worth Contact the deal by contacting the jeweler, and when it is supposed to purchase antique copies - to museum experts.
The cleanliness of the alloy determines the softness and compliance. Vintage coins were tried to the tooth, and if they had traces from the teeth, it testified to their authenticity.
The noble metal is deprived of its softness, if you add copper, silver, platinum or zinc alloy.
Price
To answer the question of the value of the products from worm-gold, it is necessary to find out which specifically the sample is considered, as the Chervonny Gold is a rather extension concept. He cannot have a sample less than the 916th. Based on the sample, the price tag can be up to 2,500 rubles per gram, taking into account the fact that the cost of the product of the 585th sample ranges in the range of 1,600 rubles per gram.
To determine the price you need to know exactly what a sample has alloy. Today, under this term, the marking alloys are understood: 916, 958, 980 and 999. This means that in the ingot of 1 kg weighing 1 kg, for example, 916 g of gold, and everything else falls on the ligature (copper, nickel). Accordingly, if the ingot of 1 kg, it has 999 g of gold and only 1 g of other inclusions - at the moment it is the highest sample.
It should be noted that the price depends not only on the course of gold, established at the moment in question on the global gold and foreign exchange fund, but also on the form in which it is located.
Bank bars As an oz, labeled with the test tube, are offered by banks at one price. In Lombard Take gold scrap, as a rule, at a low price. Evaluation of jewelry It is carried out not only by the amount of noble metal, but also in terms of the quality of work performed, according to the presence of precious stones or inserts from other metals, and so on. Respectively, The retail cost of them can also be different . Wherein in the quotations of precious metals On the global stock exchange, gold can not occupy the position below the silver and above platinum or palladium.
Application
Currently, Chervonny Gold has limited use. In circles of Russian jewelers, the most popular alloy of the marking of the 585th samples, less frequently used 750th. It has great strength, resistance to mechanical damage, oxidation. It retains the initial transportation for a long time. Products of the 750th samples in the domestic market is very small. At the same time, the worber gold of any sample is in demand in some countries as decorations at its high cost.
In these developing states, a high level of inflation of the national currency, so at the first opportunity, people seek to invest money in precious metals, preferring them in the form of decorations on their own body.
The main branches of the use of worber gold include several areas.
- Electrical industry, more precisely, electronics. Excellent conductivity and corrosion resistance make it possible to use an alloy in electronic devices to strengthen contacts by gilding.
- Jewelry production. To strengthen products, increasing the quality of valuable metal, additives of ligatura to pure metal are used to impart extraordinary colors.
- Medicine, especially dentistry. Production of crowns, bridges, orthodontic devices.
- Financial sphere. Each country has a gold reserve - the ingots of the highest 999th sample. With an unstable economic situation, they are considered the most profitable investment investment as states and individual citizens.
- Aerospace sphere. For lubrication of some mechanical parts, surface coatings inside the spacecraft and protection from the inside of astronauts from radiation.
- Sport. For the manufacture of gold medals. Currently, no pure gem metal is used for this, and the coating is gilding. But the tradition with serving awards is preserved at the same time.
Currently Gold - Solid and Industible World Financial Equivalent . Many world states wink their own gold reserve in case of collapse of a cash system based on a dollar and euro. Thus, the Chervonny Gold is still considered the main monetary measure.
