What is cupronickel, brass and why does jewelry need rhodium plating?

Brass has been known to people since ancient times. In the Roman Empire, coins were minted from it and used to produce household items and jewelry. In Ancient Greece, judging by the description of the shield of Hercules, it was used by gunsmiths to complement armor with decorative elements. In the Middle Ages, scabbards were made from brass, and, for example, in Rus' they were once used for casting samovars.

Brass is not a pure metal, but an alloy of copper and zinc

If in ancient times copper and zinc ore were smelted to obtain it, then in the 18th century they began to smelt copper and pure zinc. It can be either two-component with alloying zinc, or multi-component, when nickel, tin, lead and other elements are added to the alloy to increase casting properties.

As a rule, the alloy is yellow in color, but due to additives it can have red and green tints.

It is resistant to corrosion and high temperatures, which is why it is sometimes called “eternal metal” for its wear resistance. Brass is used in the production of instrument parts, fittings, wind instruments and various church utensils.

Brass jewelry harm

Hundreds of years ago, Egyptian pharaohs decorated their hands with copper bracelets.
According to the healers of that time, these decorations have magical powers. They were equated with talismans that protected people from many ailments. The Egyptians were not wrong. Indeed, without copper a person simply cannot exist. It must be present in the human body. In the last century, much was written in the media about the medicinal properties of products made from copper. It was believed that this metal differs from others due to its magical properties . It can save a person from many diseases.

Under the influence of the articles, many craftsmen began to create copper products on their own. A variety of objects were made from copper wires and five-kopeck coins:

Since ancient times, copper coins have been applied to a bump or severe bruise. All this was done for only one therapeutic purpose.

Importance of copper for the body

Even ancient scientists knew well that without copper not a single anabolic process takes place, in other words, simple substances turn into more complex ones. Without this noble metal, the life and functioning of certain enzymes is impossible.

According to research by medical scientists, it was found that copper is a very important trace element, without which normal development of the body is impossible. It affects the metabolism occurring in the body and affects blood cells . It has been established through extensive experience in animals that if copper is removed from the body, it will stop absorbing most of the vitamins.

If this microelement is deprived of connective tissue, a process will begin very quickly, which will result in the appearance of tumors. Unfortunately, our body cannot produce copper itself; it must come from other sources. This is exactly what happens. Food becomes a source of copper.

Scientists have proven that the benefit of copper compounds is to enrich cells with oxygen , they normalize the processes of formation of blood cells. Copper microelements perform some vital functions:

1. Strengthen bone tissue;
2. Neutralizes radicals;
3. Destroy viruses;
4. Remove fungi;
5. Cleanse the intestines;
6. Normalize the functioning of the upper respiratory tract.

When a person wears a copper bracelet, several types of exchange are activated:

1. Mineral;
2. Saline;
3. Water.

In addition, existing inflammatory processes are relieved.

All of the above properties indicate the healing properties of copper.

Today, copper is also used by gynecologists. The intrauterine device is made from it . In 2008, copper was officially given the status of a medicinal element with a bactericidal effect.

How much copper should be in the body

Every day a person should receive approximately 4 milligrams of copper; without this amount, he simply cannot exist. The decrease in copper reserves in the body is affected by:

1. Poor nutrition;
2. Diseases of the stomach and intestines;
3. All kinds of diets.

When a copper deficiency , a person develops all sorts of diseases:

1. Low hemoglobin;
2. Arrhythmia;
3. Ischemia;
4. Diabetes;
5. Nervous diseases;
6. Psychosis;
7. Headache;
8. Decreased immunity;
9. Quick fatigue.
10. Tumors;
11. Diseases of the bone and muscle system.

If the connective tissue is deprived of copper, “lupus erythematosus” . Studies have clearly shown that this element plays an important role during the formation of hemoglobin.

Copper activates the work of iron accumulated in the liver. It improves bone marrow function, regulates vitamin metabolism, and affects energy metabolism. Its effect on the body is very similar to the effect of insulin.

Doctors have come to the conclusion that compensation for the lack of copper in the body must occur. The simplest method used by ancient Egyptian healers is to wear a copper bracelet.

Its high effectiveness has been proven by modern research. Therefore, today such copper bracelets are becoming popular again.

Therapeutic measures using copper

Magnetic therapy has found wide application in modern medicine. Just a few sessions are enough to strengthen the body and strengthen the immune system.

Modern technologies make it possible to produce a copper bracelet with magnetic properties. Thanks to such technologies, you can restore your health without consulting a doctor.

If you constantly wear this healing bracelet, the body experiences:

1. Improving blood circulation;
2. Removing toxins;
3. The supply of micronutrients is normalized;
4. Temperature drop.

Why has the popularity of the copper bracelet grown?

The first country where copper bracelets appeared was America. The news of this healing jewelry quickly spread across the planet. The rapid popularity of the copper bracelet was so high that even the most inveterate skeptics came to the conclusion that such a bracelet could not be a fairy tale or some kind of myth.

Thirty years have passed since the discovery of the copper bracelet . Of course, the popularity that the first copper bracelets had has faded a little. However, she did not disappear completely. And today many people enjoy wearing them all the time.

There is nothing surprising about this. If a person has been trying for many years to recover from a disease that does not respond to classical methods of treatment, he turns to unconventional methods. After all, there are people who say that a copper bracelet helped them heal.

Does a copper bracelet help - myth or reality?

It is very difficult to declare only one opinion on this issue. It is better to turn to medical studies conducted repeatedly and the conclusions drawn. After all, doctors were also interested in the effect of such simple decoration on the human body.

In different countries, scientists tested copper bracelets on patients with any disease. In America, Professor Harrison studied the bracelet's ability to reduce pain in rheumatic diseases. English doctors tried to understand how the bracelet works on the joints.

They all came to the same conclusion. The positive qualities of a copper bracelet come down to the placebo effect.

Science has also proven that a copper bracelet can have a felting effect on blood vessels. The main merit of this property relates not so much to copper, but to the magnets attached to the bracelet. Thanks to a small magnetic field, the blood becomes more fluid. With a strong magnetic field, the opposite effect occurs.

There is still no scientific evidence It is still very difficult to say that wearing the bracelet led to recovery. After all, recovery may also be associated with the effect of medications or a spontaneous weakening of the pain effect.

What is the effect of a bracelet worn on the right hand:

1. Headache;
2. Depression;
3. Insomnia;
4. Physical fatigue;
5. Low blood pressure;
6. Tuberculosis;
7. Diabetes;
8. Sexual diseases;
9. Arthritis;
10. Bronchial asthma;
11. Arthrosis of the joints.

The effect of a copper bracelet constantly worn on the left hand:

1. Hypertension;
2. Angina;
3. Tachycardia;
4. Arthrosis;
5. Haemorrhoids;
6. Arthritis;
7. Heart failure.

Important! The bracelet should only be worn unlocked . This will not allow negative bioenergy charges to appear. When the body comes into contact with the bracelet, the body absorbs a small dose of copper, which enters the blood and maintains the required amount of copper. To obtain the maximum healing effect, the weight of the bracelet should exceed 50 grams.

Side effects

For all its positive qualities, copper bracelets also have a negative side. Therefore, before you start wearing this medicinal jewelry on a regular basis, you should consult your doctor.

Sometimes you may experience:

1. Nausea;
2. Dizziness;
3. Metallic taste;
4. Intoxication.

In such cases, you should immediately stop such therapy and remove the jewelry.

What are the benefits of copper jewelry?

Share! Share! Share! Share!

Red, like blood, intertwined like the roots of a tree in the ground, revered by all nations for its ability to heal many physical and mental ailments... All this is Copper .

Our ancestors believed that she was born from drops of the blood of the World Tree, shed by the proud Chernobog, who decided to throw off the Gods from Iriy.

Types of copper bracelets

Copper bracelets, which have beneficial properties, can be found in many people’s home collections. First of all, this is due to their originality. Most copper bracelets are handmade, making each accessory unique. Secondly, the modest price plays a big role. In addition, copper bracelets go well with any style of clothing. They can be worn with both classic outfits and jeans and T-shirts.

Another important detail is the health benefits. Copper can strengthen and cleanse the body, and also helps remove excess fluid from the body and improves metabolism. This metal is unique in its properties.

What types of copper bracelets are there? Today you can find the following types on sale:

• made of pure copper (not equipped with any coating);
• patinated copper (having an antique coating, which can be of any shade - green, brown, blue, reddish);
• copper with varnish coating;
• copper with stones;
• from alloys containing copper (alloys of zinc, aluminum, tin and copper).

Why copper and brass darken and how to care for jewelry

Today I want to talk a little about whether copper and brass darken, why they leave dark marks on the skin from close, prolonged contact, and how to care for copper and brass jewelry.

The photo shows example rings that are no longer available. But a batch of the same ones will be on sale in the near future :)

I have written more than once that, of course, brass and copper darken and oxidize

because they are not precious metals. I am often asked about this and I have never hidden the fact that jewelry can oxidize and darken over time. And you need to know this and be prepared for this when you purchase jewelry made from such non-traditional metals. After all, even silver oxidizes over time.

But! I want to point out that the reaction of metal to your body is very, very individual.

. I will speak in completely non-scientific simple words. It all depends mainly on the acidity level of your body.

If the acidity is high, then copper and brass will definitely darken on you and leave dark marks, for example from rings and bracelets.

If the acidity level is normal or reduced, then the jewelry you wear will not oxidize at all, much less leave marks, and will shine like new for a long, long time. I knew this before, but recently I proved it to myself experimentally.

I'm telling you :) I have always had a terrible sweet tooth and copper and brass have always oxidized on me. I have a copper swoosh ring (made by me, of course), which I always wear, never taking it off. I sleep, wash, live in it. And I used to wake up every morning with a black mark under this ring.

And recently, almost a miracle happened - I almost lost interest in sweets))) Well, it’s not that I don’t eat sweets at all, but much less often and not even every day)). So my ring stopped oxidizing and leaving marks. I wake up in the morning and the ring is shining, my finger is clean and there is no dark streak on it.

By the way, if anyone hasn’t understood yet, sugar acidifies the body, raises the level of acidity, and therefore copper and brass react to such changes. But as soon as I eat a chocolate bar or a cake, the next morning the ring darkens again, although not as much as before.

It turns out to be a kind of litmus test) I, of course, do not encourage everyone to stop eating sweets at once so that the jewelry does not darken, but I think that it is useful to share such experience.

And now a few words about how to deal with this, how to care for jewelry made of copper and brass:

1. For better preservation of jewelry, it is best to store it in a zip bag or closed box. They say that a piece of chalk placed in a jewelry box will protect it from oxidation; I haven’t tried it myself);
2. After each wear, it would be good to wipe the jewelry with a rough woolen cloth. Or soft flannel;
3. I recommend periodically thoroughly rubbing your jewelry with a silver cleaning cloth. It also works on copper and brass, but you will have to try a little longer to make the jewelry shine again;
4. If the decoration has darkened, you can soak a piece of cloth in a solution of vinegar and table salt and wipe it thoroughly. Then rinse under running water;
5. If the jewelry is not patinated and has fairly wide flat surfaces, then you can clean it with a toothbrush and a drop of toothpaste. But this must be done very carefully, especially if the decoration contains stones and small elements, so as not to damage them.

As I already wrote, I safely lost the camera with films from the trip somewhere in the vastness of Hungary, so I don’t have a single film frame from Budapest. But there are a few photographs from Croatia and the festival. Today I will show you Croatia. These photographs depict the small, cozy, beautiful town of Porec. In general, I don’t really like a holiday at sea of ​​this purely resort-tourist type. For me, the sea is a tent and a wild beach. But the town itself is very nice and beautiful, with old streets, lanterns, cozy restaurants and lots of flowery balconies.

Back at the beginning of summer, I had an image that was firmly lodged in my head and demandingly asked for a way out. Well, I already wrote that I missed the summer in terms of photography)) And when it was already the end of September, I woke up and decided that under no circumstances should I miss this image and leave it until next summer, otherwise it will fade and the moment will be missed.

In general, it was the end of September (or even the beginning of October), it was already quite cold and we went into the forest to film. I don’t know how to clearly describe the picture and thought of my photo shoot; it’s always rather blurry images and moods. And here I saw a child of the forest growing from the ground, from soft, wet green moss. I shot on film, medium format and 35mm.

There weren't many successful photos because it was cold and we were in a hurry to keep the model from freezing, but of course she was still frozen. In general, I made a valuable conclusion for myself - everything should have its time and summer shots should be taken in the summer, and not in the cold autumn.

But something did work out and that makes me happy, because if the entire shoot yielded at least 2-3 decent shots, then we didn’t waste our time) Medium format first..
(moreCollapse)
In the summer I dreamed that my autumn would be quiet , peaceful, filled with warm comfort and beauty. So that it would be a real, classic autumn with tea by the fireplace and a harvest of ripe vegetables. In the end, this is exactly the kind of autumn I had. Thoughts materialize;) It's like a little life. Autumn is a gift from nature, a fleeting, unsteady quintessence of beauty. How I want to grab her by the tail and hold her silently in order to enjoy these last warm rays and crazy beautiful colors longer. But all the leaves have already fallen off and the sun has not been warm for a long time, and the air already smells of winter. Now is such a difficult period when everything is gray - the earth, houses, sky, even the air. And there are still several months ahead with almost no color. And now I’m looking at the September and October photographs and I can’t believe that this happened, and it happened almost just now... Film. Pentax MZ-7, kodak gold

(moreCollapse)

I fell into autumn hibernation a little here and therefore began to write much less often, don’t be angry :) I don’t really want to do anything except lie under a soft warm blanket, eat candy and read interesting books. Actually, this is what I have been shamelessly doing all last week)) And this state is logical for me, because, firstly, almost winter cold has set in and even snow was falling, and secondly, after active creative periods, I always have a period of fatigue and some devastation . So I'm still gaining strength. This, of course, does not mean that I am completely idle, but the work is going very slowly)) In general, I have a lot of interesting things that I am going to show you in the near future - these are new photographs and new jewelry. Also, because of the onset of cold weather, we will soon be moving back to the city, to an apartment. Ehhh, goodbye, wonderful sunrises, sunsets, fogs, fields and birds...

Is anyone here still suffering from a mild, pleasant autumn spleen?)

All summer I planned to do a lot of photo shoots with people. But the summer somehow passed unnoticed, and I still didn’t have time to shoot anything, although my head is still bursting with ideas and desires)) So, in September I came to my senses and decided to urgently take the bull by the horns, otherwise the cemetery of ideas will grow to incredible proportions ) It turned out that there are many beautiful, artistic and interesting models nearby, you just have to extend your hand! I have already told you that I fell in love with film completely and irrevocably, and the first photographs of people on film only strengthened my love and now I don’t even want to pick up a digital camera. Today I will show you a photo shoot with the wonderful, airy and incredibly graceful Anya. This is such a light, sleepy, calm photoset. We wanted to convey the image of a beautiful and falling asleep autumn, I think we did a good job). In general, I'm always very worried when I shoot on film - there's always the possibility that I'll mess up and the photos won't turn out. But here almost all the photos turned out, it was even difficult to choose.

I shot with two cameras: a Pentax 35 mm and a medium format Yashika. First, as you yourself understand, there are 35 mm photos.

While my apple pie is baking, I’ll write a couple of lines about the current one in brief)

• Lately I've watched a bunch of unexpectedly good films and continue to do so with pleasure) Maybe I'll write a post about it someday.
• Over the past week, 2 fabulous series of photographs were created with absolutely beautiful girls. Of course, on film, now I’m completely obsessed with it)) All I have to do is develop 2 slide films and I’ll show off)
• Now, more than ever, I wildly want to explore new spaces in creativity. Desire burns and stabs. But there is one problem: I have a thing for real real books, no matter what they are - fiction or textbooks. I definitely need to hold a book in my hands, feel its cover and flip through the pages, this is the only way I can establish direct contact with the contents and truly get into it. So, the very necessary educational literature is not available in Russian online stores. I don't despair, I continue to wait. There are 2 backup options: buy foreign literature and terrorize your man so that he translates all this for me)) or print out what you download and study from dull printouts))
• And the most important news!
  in the coming days I will launch a terribly interesting giveaway, hurray! There will be many and different prizes. Do not miss;)

And some autumn film photos

(more beautyCollapse)

Your Sabi: *And yet I absolutely love photographing vegetation and everything that turns green, blooms, grows, reaches for the light, breathes inaudibly and invisibly.

And I’ll probably never get tired of crawling with a camera around trees, bushes and blades of grass)) Because there is nothing more real than what was created by nature and grew in the shade of forests or under the bright sun of meadows.

And recently my golden-armed man repaired a film Pentax for me, which I successfully unpacked in Istanbul) and now I’m inseparable from him again, hurray! And now all my walks through the forests and fields I am accompanied by a Pentax and a couple of spare films) I’m learning to shoot on film without being timid and without relying on digital photography. And it seems that it’s already working out a little. I'm crazy about film photography - it's so simple and so sincere.

How to tell if a copper bracelet is working

In fact, this interests a lot of people. Most people question all types of alternative medicine, and copper jewelry is no exception. How do you know that the bracelet really works and is beneficial?

First of all, this can be determined by your own well-being. The second sign is a green mark on the skin under the bracelet. There is no need to be afraid of it - it will not cause harm. This simply means that copper ions penetrate the skin. These stains can be washed off very easily with soapy water.

Zinc alloy: special properties and main varieties

Thanks to archaeological excavations, it was discovered that zinc products began to be used around the 7th century AD. This metal was very common due to a number of useful properties. Zinc alloy can be made from various substances, which determine its characteristics. This material is used in various industries, including jewelry.

Properties and characteristics of zinc and zinc alloys

The characteristics of zinc alloys are largely determined by the properties of zinc. This metal is bluish in color, is not found in its pure form, and usually contains impurities that change its properties. Pure metal is obtained as a result of several reactions.

Zinc has the following chemical properties:

• When heated, it reacts with hydrogen sulfide and water to release hydrogen.
• Does not react with nitrogen and carbon.
• It reacts with alkalis to form zinc acid salts - zincates.

Zinc is a very durable material. Its ductility increases when heated. If it is heated by more than 210 degrees, this may change its shape. At low temperatures the substance melts.

What does zinc alloy look like?

The amount of impurities depends on the methods of metal extraction, the characteristics of its processing and the zinc grade. Most often you can find impurities in the form of nickel, chlorine, fluorine and lead. Usually, when creating zinc alloys, pure zinc is used, since the presence of impurities degrades the quality of the material:

• tin makes the alloy too brittle and brittle;
• in the presence of cadmium, the ductility of the material decreases;
• lead increases intercrystalline corrosion of the material and promotes its dissolution in acids;
• the presence of iron increases the hardness of alloys, but reduces their ductility;
• Arsenic causes the alloy to become brittle and non-ductile.

Therefore, to improve the characteristics of zinc alloys, zinc is first purified from impurities. And then they use pure metal, which is alloyed with various components.

Advantages and disadvantages

Most zinc alloys have the following advantages:

• they are very durable and are not damaged by mechanical stress;
• resistant to corrosion;
• have good casting qualities and can be used to create even small elements;
• Over time, they practically do not age.

However, even small amounts of impurities worsen the characteristics of the alloy. They lead to a decrease in melting point, swelling, and contribute to the appearance of cracks. Therefore, zinc alloys must be created in compliance with all technologies, and the amount of impurities in them should not exceed 0.005%.

Many people ask whether zinc alloys darken or not? This is another drawback of the material. Zinc alloys may darken over time. Moreover, the darkening usually spreads over the entire surface of the material.

This is caused by the formation of an oxide film on the surface of the material. It forms at room temperature after contact with air or water.

Therefore, to avoid this, electroplating is required.

Types of zinc alloys

Zinc can be alloyed with various substances, which will determine the properties of the resulting material. Alloying pure zinc with copper, aluminum and tin can improve its performance. The resulting composition will be of higher quality than the pure substance.

Copper and zinc

The copper-zinc alloy is called brass. This alloy has been known for a very long time. It was first made by alloying zinc ore and copper. It was only in the 18th century that an alloy of copper and zinc metal was first created.

Moreover, both components can be taken in different proportions. As a result, several types of brass are distinguished:

• Green. Contains 60% copper and 40% zinc.
• Golden. It contains 75% copper and 25% zinc.
• Yellow. Contains 67% copper and 33% zinc.

Brass is an alloy of copper and zinc

Brass lends itself well to pressure processing. It is characterized by high mechanical properties and good corrosion resistance. But in air, in salt water and carbon dioxide solutions, brass is unstable and quickly becomes covered with a dark oxygen film.

Externally, brass looks more beautiful than copper and is characterized by better corrosion resistance. But as the temperature rises, the intensity of corrosion also increases. It can be triggered by high air humidity, the presence of ammonia or sulfur dioxide. Therefore, to prevent corrosion, the material is subjected to low-temperature firing.

Brasses do not lose their properties when the temperature drops. This allows them to be used as a structural material. But at high temperatures (more than 200 degrees), phenomena of brittleness of brass can be observed.

Tin and zinc

The alloy of zinc and tin is characterized by high protective properties. Does zinc alloy with tin rust or not? This material is very resistant to corrosion. An alloy with 20-25% zinc and 75-80% tin has the best anti-corrosion properties.

Therefore, it can be used in conditions of high humidity, and its appearance will not deteriorate over time. The higher the zinc content in the alloy, the lower its corrosion resistance.

If the alloy contains 50% or more zinc, its corrosion resistance is close to that of pure zinc.

The alloy of tin and zinc has the following advantages:

• It is very ductile and can be easily soldered.
• The polishing of the deposit lasts for a long time.
• Has high corrosion resistance.

Due to the presence of the above properties, an alloy of tin and zinc is usually used in the electrical and radio industries. Products made from it are very durable and resistant to external influences.

Aluminum and zinc

Most often, an alloy of zinc, aluminum and copper is created, which is called TsAM. It also contains a small amount of magnesium.

This alloy has a low melting point and is easy to cast. Products made from it are very durable and resistant to the environment.

There are several high-quality zinc-aluminum alloys, which are designated TsAM 4-1, TsAM 4-3, TsAM 10-5 and others. They contain approximately the same amount of aluminum, but different amounts of magnesium, nickel and copper. The cost of an alloy of aluminum and zinc is lower than that of tin and zinc. Therefore, products made from it are much cheaper.

Scope of application

Zinc alloys are widely used. They are used in the following industries:

• In the automotive industry. Door handles, mirrors, and parts for car interior decoration are made from zinc alloys.
• When creating jewelry. Zinc is alloyed with gold, thereby increasing its ductility and malleability. This makes it easy to connect small parts to each other.
• In medicine. Zinc alloys are used to make medical furniture and devices. And zinc oxide is a good antiseptic, so it is added to various ointments and medicines.

Zinc alloy is used in automobile manufacturing

Thus, zinc and its compounds are used in many fields. But the substance is most widely used in the automotive industry.

Types of zinc alloys by purpose

According to their intended purpose, zinc alloys can be of several types:

• Deformable. 15% - aluminum, 5% - copper, more than 1% - magnesium. It is made in the form of sheets or rods. The properties are similar to brass.
• Foundries. They are made by adding 3-4% copper and aluminum to zinc, as well as 0.05% magnesium. They have good fluidity. Therefore, they are manufactured through injection molding or mold casting.
• Anti-friction. They contain 10% aluminum, 5% copper and 0.1% magnesium. Manufactured by injection molding. They have a low coefficient of friction and are used in the automotive industry.
• Solders. They are used for soldering aluminum parts. Usually include impurities - metals. This increases their strength.
• Typographic. They contain 7.5% aluminum, 2% magnesium and approximately 4% copper. Such alloys are very durable and cast well into molds.
• Protective. They contain no more than 1% aluminum and a tiny amount of silicon and magnesium. Resistant to corrosion even in damp environments. Therefore, such alloys are used as protective materials.

Zinc alloys have proven themselves well and are widely used. But when creating them, proportions must be accurately taken into account, otherwise poor quality material will be obtained.

Zinc alloy in jewelry

Externally, zinc alloys resemble noble metals. Therefore, they are used in costume jewelry to create inexpensive jewelry. Zinc alloy jewelry looks expensive but is easy to create.

Is zinc alloy harmful? In fact, it has no effect on the human body. But, nevertheless, it is better to purchase good quality jewelry. Usually, a special alloy is used to create jewelry, which is called costume jewelry. The most commonly used is brass or an alloy with aluminum. Externally, such products resemble gold and silver.

Is zinc alloy harmful in jewelry? No, so you can safely buy products made from it. After all, if it had a negative impact, making jewelry from it would be prohibited.

Thus, zinc and zinc alloys are widely available. They are used in medicine, automotive industry and even in jewelry. These are high-quality and sustainable materials that practically do not change under the influence of environmental conditions.

How to make a copper bracelet yourself

You can not only buy a beautiful bracelet with useful properties, but also make it yourself. To spend your time usefully and create your own accessory, you will need the following:

1. Copper wire. It must have certain parameters: length - 15 cm, width - 1 cm, thickness - 3 mm. The exact dimensions depend on the size of the wrist of the future user.
2. If you want to add decorative elements to the bracelet, you will need beads, rhinestones or stones of your choice.
3. Sandpaper intended for sanding.

The wire should be sanded at both ends and the ends should be rounded. After this, the product is braided at your own discretion. If desired, use beads and other decorative elements. You should twist the wire at the ends, adjusting it to the size of your specific wrist. Such a lightweight product is not only beautiful, but also useful.

Brass jewelry is harmful - Metalist's Handbook

Hundreds of years ago, Egyptian pharaohs decorated their hands with copper bracelets. According to the healers of that time, these decorations have magical powers. They were equated with talismans that protected people from many ailments. The Egyptians were not wrong. Indeed, without copper a person simply cannot exist. It must be present in the human body.

In the last century, much was written in the media about the medicinal properties of products made from copper. It was believed that this metal differs from others due to its magical properties . It can save a person from many diseases.

Under the influence of the articles, many craftsmen began to create copper products on their own. A variety of objects were made from copper wires and five-kopeck coins:

Since ancient times, copper coins have been applied to a bump or severe bruise. All this was done for only one therapeutic purpose.

Dangerous jewelry: myth or reality?

Man has been wearing jewelry since time immemorial, and its history begins perhaps more than 80 thousand years ago during the Paleolithic era. This conclusion was made by archaeologists who discovered beads and bracelets made of sea shells in a burial of that period in Asia Minor. And no matter how changeable fashion is, people have always sought to decorate their suit or just their body.

Jewelry masterpieces can be precious and not very precious, multi-carat and modest, stylish and tasteless, ancient and modern. But there is another gradation, the existence of which few people think about, but which can in some cases become the main one, because the price of falling into the wrong category is too high. We are talking about what happens:

• Just decorations.
• Decorations harmful to health.
• And even life-threatening.

There is no exaggeration here. Only bare facts that make you think, stop and turn back.

Let us leave it to the conscience of astrologers and traditional medicine charlatans for their statements that “emerald affects the kidneys of those born on the fifth lunar day of the seventh month of the year,” and “diamond causes blindness in those who receive it dishonestly.” We are talking about a real danger that modern science can simply explain.

Nickel and allergies

Many women (and sometimes men), of course, have noticed that prolonged exposure to metal watch bracelets, belt buckles, some jewelry, and even rivets and buttons on jeans causes a strange skin reaction. The place of contact with the metal begins to itch, becomes covered with a small rash and itches desperately.

At first, this is not given any importance, but when both the time required for the occurrence of an allergic reaction and the area of ​​contact are significantly reduced, and the reaction to metal nevertheless becomes more and more serious, the victim turns to a dermatologist and does not believe his ears.

It turns out that there is contact dermatitis, the cause of which is an allergy to nickel.

This metal is part of many alloys that are used in the manufacture of all of the above jewelry. For the occurrence and development of allergies, particles do not need to enter the bloodstream, and therefore both a belt buckle and a freshly inserted piercing have an equal chance of success in involving their lucky owner in the whirlwind of an allergic dance.

What does a copper bracelet look like?

Any copper products are distinguished not only by their visual appeal and originality, but also by their practicality and reliability. Bracelets made of this metal are worn not only for decoration, but also as a medicinal item. Some users claim that this decoration has healing properties, especially in relation to the cardiovascular system.

Recommendations for choosing a copper bracelet

In order for a copper bracelet to be beneficial, you should choose it correctly. The main parameters should be the following:

• Weight. This parameter should ideally be between 40 and 50 grams;
• Width. No more than 14 - 15 mm is recommended. This requirement is the same for everyone: women and men, as well as children;
• Form. A strictly open ring is a circle. It is due to this shape that a useful magnetic field is created;
• Size. The bracelet should fit fairly tightly to the skin along its entire width and circumference;
• Brand of copper. Strictly MV. This label is guaranteed to offer approximately 99.9% pure copper. Only such a bracelet has all the positive properties.

Important! It is unlikely that you will be able to visually determine the quality of the metal. Therefore, purchases should only be made in a trusted store.
