One could I be pardoned if, like Rip van Winkle waking up after a 20-year sleep, he finds himself most pleasantly surrounded by a plethora of objets d’art that have mushroomed, replacing the traditional framed pictures that have always adorned walls. I Instantly, he’s amazed to find them made of metal, a material normally used in construction, not in art. He’s even more delightfully surprised to find that such a material – which sometimes includes parts one can only find in junk yards – could be transformed into a thing of beauty and a bundle of paradoxes. I Metal, for instance, is heavy, yet here are metal sculptures ranging from delicate mobiles to gigantic stabiles that flutter or sway in the slightest wind. It’s cold, yet as a metal wall sculpture or any abstract metal art, the emotions it elicits is anything other than cold. He’s also amazed to find them everywhere – for instance as a 16-meter, 50-ton vermilion leviathan like Alexander Calder’s Flamingo which adorn the Federal Plaza in Chicago, or as an exquisitely delicate and life-like praying mantis adorning a lighted corner. From indoor metal wall sculptures decorating walls, to gigantic stabiles jazzing up public sites, metal art is here. Here are some facts would-be metal art aficionados might want to know.

Casting
Some metal sculptures are made by casting, sometimes called lost-wax casting. One of the most famous in this type is Benvenuto Cellini’s Perseus with the Head of Medusa statue in bronze with its startling detail and immense grace. I Here, the artist pours molten metal-which can be aluminum, steel, bronze or some other alloy — into a mold, which, after some tedious process, is removed, revealing the masterpiece inside. Then the masterpiece is cleaned up, and, often, a patina is added. I Casting dates back 6,000 years, its oldest surviving example being a copper frog from 3,200 B.C.
Fabricated Sculpture

Here, the artist welds metal pieces together, which, often in combination with lighting accent results in a breathtakingly beautiful piece of art possessing the power to transform any drab corner into an electrifying area of glam and even chutzpah. These art pieces endow the lucky owner instant pizzazz, marking them off as possessing style and grace. I
Patinated copper abstract contemporary wall art is an example. I Other examples could be abstract brass or steel sculptures given a torch coloring or transparent tint finish. I All share the same characteristics: I handcrafted, hand-painted, and unique. I There are small ones and big ones. I Some are intended for outdoors, others for indoors. I Each artist has its own style, and some have even gone so far as to specialize in one specific category, honing their skills to perfection. I There’s one artist, for instance, who specializes in animals and insects, and whose frogs and I praying mantises are incredibly life-like and look like they couldn’t possibly be made of metal. There’s practically everything for everybody. There are human forms, animal forms, and yet still others which can’t be described by any other adjective than “alien” form. I

Found Art
One artist in this category – which is also called “found object,” I “objet trouve,” “ready made,” or “junk art” — describes his work as “sculpture fabricated from twentieth century by-products,” which aptly describes art of this type. I Found art sculpture differs from fabricated sculpture in one significant way: I found art starts with an already finished product, e.g., a piece of copper tube, an elbow joint, a nut, a dented car fender, the base of a table lamp, and turns it into something totally different from the original. I In this sense, found art finds kinship with the green movement slogan: I re-use, re purpose, recycle.

Silver jewelry has been around for a long time and has been enjoyed by generation after generation since as far back as 5000 B.C. According to historical investigations and reports Egyptians used silver for jewelry, ceremonial ornamentation, and for bartering and tombs have been discovered containing silver that dated back as far as 2900 B.C.

Although there are many modern technological ways to work silver today this wasn’t the case back when silver first began to be used to make jewelry. At the time the process for working jewelry involved either the use of a hammer to get the desired design and look or casting and pouring silver into the desired shape for a piece of jewelry. A third way that silver was worked into silver jewelry in ancient time was through filigree techniques. This is the process of taking thin silver and twisting it and wrapping it into intricate designs that can be held together by soldering.

All of these ways that were once used to work silver provide for a fairly rough, simple jewelry but it just goes to shoe how long individuals have been enjoying the beauty of silver and wearing it to make a fashion statement or as a sign of wealth. The beauty of the low cost precious metal has not been lost on a generation yet to date. You can find gorgeous pieces from all different points in history and from all different regions of the world.

Many Indian tribes used silver to make jewelry. Often you will see these pieces around still today; many of these pieces also have turquoise in them. Silver and turquoise go beautifully together and make for a lovely piece of jewelry. The contrast between the two colors is brilliant.

Another part of the world that is known for their use of silver is Mexico. Silver pieces made in Mexico have a wide selection of stones in them. These stones range from inexpensive coral, which is a beautiful red color, to a pricier boulder opal, which has a brilliant mixture of colors, to a simple emerald with all of its elegant beauty.

Other parts of the world that silver comes from include Peru, Chile, China, Poland, and Australia. All of these countries have been mining silver for many years with Mexico and Peru being the longest, mining silver dating back as far as 1546. And the silver that these countries mine is not only useful for jewelry but for other things as well, such as cutlery, and heat conductors.

Silver jewelry has been a profitable industry for many, many years and from all indications it appears that the inexpensive precious metal will continue to be popular in future generations too. Silver jewelry will not loose its elegance and simplicity from over years that can be worn anytime we want and for that may be compared with gold jewelry. I have a feeling that many pieces from the past will stick around to be enjoyed for many years to come.

Amber, which is actually fossilized pine sap, has become, through the creativity of men, part of jewelry. Amber jewelry is today more or less a part of our lives. The difference between now and decades ago is only one: everyone can afford a piece of amber jewelry today and doesn’t know what to do with it, but a long time ago people suspected its powers and a lot of them couldn’t afford to own this kind of jewelry.

The first name given to Amber was electron. After that, around the sixth century B.C., the scientists of that time discovered that, if you rubbed amber against a wool cloth, it became electrically charged. Because of its property it could attract small pieces of paper, fact which amazed the people of that time. Carrying a negative electrical charge, it was thought that the stone itself was able to draw power and energy into its bearer. This belief helped make the stone famous and valuable. People started using it in amber jewelry and making amulets and magical objects. Besides being able to attract energy, it was believed that it aided the intellect. It was prescribed for a lot of curious illnesses like memory loss, anxiety and eccentric behavior.

Amber jewelry was known for its capacity to influence the mood of the bearer. People though that wearing amber jewelry would help them and that the small yellow-brown stone could lighten the burdens of their lives filling their spirit with white light. The results of its actions were supposes to be a feeling of happiness and joy. From the healer’s point of view, the idea was that amber jewelry somehow activated the altruistic side and made people realize the power of their spiritual intellect to the fullest.

For thousands of years Amber has been regarded as a precious substance for its warm beauty. Because no one knew then were it came from, it was thought to be of divine origin. People believed that no harm could come to the one that wore amber jewelry because the stone would protect him. Because of these beliefs the stone become used for medical purposes. Philosophers and alchemists have tried for a long period of time to explain how the amber stones came to be and looked the way they did. Around the first century A.D. a Roman senator and historian recorded a popular belief on the forming of the stone. He wrote it was formed from the urine of the lynx. The male was supposed to produce the dark colored stones and the females the lighter ones with yellow colors. Since there was no explanation to how this miraculous gem appeared, people became superstitious. Another one of the spoken beliefs was that the rays of the setting sun were concealed in the evening sea and then they were cast upon the shore in the form of the stone we all know. This is why we can say that amber jewelry is a piece of brilliant sun. Around the year 240 B.C., an astrologer, Sudines, came pretty close to the real origin of amber. He said that the gemstone is the product of a tree called the “lynx”. It was indeed the product of a tree. Amber was a resin.

The one that made the amber color and amber jewelry famous was Nero. He compared his wife’s hair to the color of the gemstone. From that point on every respectable woman, wives of the noble men at that time, started to aspire to that color and it became a symbol. The woman with the red hair that had the setting sun reflected in the evening sea trapped in her hair felt very proud of the similitude between the amber stone and her beauty. That’s why amber jewelry is regarded the way it is. A small piece of “brilliant sun” or “frozen gold” hides the mysteries of the gem in the beauty of the amber jewelry.

As for the medical use of amber, nothing can be scientifically proven. The ancient Romans had great confidence in the powers of baltic amber jewelry and they used amber in other ways too. They thought that some powder of the gemstone taken in a cup of wine could cure illnesses like fever, asthma or even infections of the throat. This type of medicine was used by the ancient Romans for ear and eye problems too. A fine powder was mixed with honey and, sometimes, with oil made from roses and it was either poured on the infected area or taken internally. Not all types of amber were thought to have healing proprieties, only the reddish stones. Nowadays, it’s also recommended to wear some amber jewelry around the neck (a necklace or a pendant) for the same purpose.

Wearing amber jewelry is a double win situation: it looks good and makes you feel good also. Precious, mysterious and miraculous, amber is by far the most complex gemstone. Its past and its aspect still fascinate a lot of people. Amber jewelry can create an effect that no diamond can ever do and is indeed, as poets say, “a slice of sunshine”.

We are offering Investment casting production.Investment casting, which is also known as the “lost wax investment casting ” process, traces its roots to the Sang Dynasty in China from 1766 B.C. to 1122 B.C. The method was brought into modern industrial use when American manufacturers applied investment casting to make high quality military parts during World War II. It was found practical for many wartime needs – and during the postwar period it expanded into many non-aircraft applications. Today, investment casting is recognized and used worldwide as a technique for producing close-tolerance metal parts at highly competitive costs.
