Google has celebrates its 13 birthday. Some one would say it is 14 birthday if you count from date domain name was created 1997-09-15. Well we are not a judge in here.

History:

Larry Page and Sergey Brin met at Stanford University in 1995. In 1996, Larry and Sergey begin joint development of search engine called BackRub.
More, the system worked on the servers BackRub Stanford, and eventually its traffic exceeded the capacity of networks of the university. Soon, friends come to the conclusion that the search engine needs a new name and eventually stop at «Google». After receiving a check for 100 thousand dollars, September 4, 1998 was filed for the registration of Google in California.

I wish Google prosperity and feel luck long time!

Today is my birthday anniversary. I will be 30 y.o.

That is, these dates tend to celebrate in grand style and make the most memorable. What is so interesting to think what this really so?

Who Discovered Silver?

No one actually knows exactly who discovered the chemical element silver or when it was discovered, but there is evidence it was known to the ancients. The name originates from an Old English Word - seolfor.

The symbol for silver, Ag, comes from the Latin word Argentum. In fact, the term silver is possibly first mentioned in the Bible, in the Book of Genesis.

The Element Silver

Silver is an element in Group 11 in the Periodic Table of Elements, known as transition metals. As element number 47, it is one of only nine other elements that were known to ancient civilizations. Silver is a very soft and malleable metal, and as with other transition metals, it conducts electricity and heat.
Silver is obtained from metal ores, including Argentite, light ruby silver, dark ruby silver and brittle silver.

Early Discoveries Of Silver

Even thought we don't know who discovered silver, there are records that indicate slag dumps were found in Asia Minor and on the islands in the Aegean Sea. These findings lead to the belief that as early as 4000 B.C. man was able to separate silver from lead.

Silver also is known by an alchemical symbol. Alchemy is an ancient pursuit that, among other things, refers to the attempt to transform other metals, including silver, into gold. So, no matter who discovered silver, we know that it was a known element thousands of years ago.

First Locations Of Silver Discovery

Though we don't know who discovered silver, a clue to the location silver was first mined is recorded by The Silver Institute, which sites Old World silver from Anatolia (modern Turkey) as the first major source of mined silver. Beginning in 4000 B.C. silver from Anatolia provided rich supplies to the craftsmen of the, then, "Western" cultures in the Near East, Crete and Greece.

Sapphire (Greek: σάπφειρος; sappheiros, "blue stone") is a gemstone variety of the mineral corundum, an aluminium oxide (α-Al2O3), when it is a color other than red or dark pink; in which case the gem would instead be called a ruby, considered to be a different gemstone. Trace amounts of other elements such as iron, titanium, or chromium can give corundum blue, yellow, pink, purple, orange, or greenish color. Pink-orange sapphires are also called padmaraga. Pure chromium is the distinct impurity of rubies. However, a combination of e.g. chromium and titanium can give a sapphire a color distinct from red.

Sapphires are commonly worn as jewelry. Sapphires can be found naturally, by searching through certain sediments (due to their resistance to being eroded compared to softer stones), or rock formations, or they can be manufactured for industrial or decorative purposes in large crystal boules. Because of the remarkable hardness of sapphires (and of aluminum oxide in general), sapphires are used in some non-ornamental applications, including infrared optical components, such as in scientific instruments; high-durability windows (also used in scientific instruments); wristwatch crystals and movement bearings; and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics (most of which are integrated circuits).

Any piece of jewelry made ​​of gold alloy is a gold, silver and copper. These are the basic components, the ratio is talking about the quality of the alloy. Gold (from Lat. Aurum - "yellow") - one of the first metals, whom he met humanity. This is a chemical element in group I of the Periodic System, ductile, has a density of 19.32 g / cm, the melting temperature is equal to 1064,43 ° C. In nature, mostly found in only native gold.

Gold - Soft and ductile metal that can forge such a condition that it will transmit light. This so-called gold leaf, which is used for decorative coatings and deposition.

• 375 - 9 carat
• 500 - 10 carat
• 585 - 14 carat
• 750 - 18 carat
• 958 - 22 carat
• 999 - 24 carat

Alloys of gold 375 samples

This alloy, containing in its composition 37.5% pure gold, and the rest - silver and copper. Usually they are characterized simply as a gold-bearing alloys, which are quickly fading in the air. The color range varies from yellow to reddish.

Alloys of gold 500 samples

Contain 50% pure gold. Variations in the amount of silver in the alloy of the metal changes color from red to green. Almost never used in production.

Alloys of gold 585 samples

Contains 58.5% pure gold, the remaining components - copper, silver, nickel, zinc and other alloys of this test are hard, well to forge and do not fade. Color varies from white, yellow and red to green of various shades. Such alloys are used for making jewelry and other jewelry.

Alloys of gold 750 samples

Alloys contain 75% pure gold. They are quite solid, can be processed and well polished. The color palette is equally diverse, ranging from bright green to all shades of red.

Alloys of gold 958 samples

These alloys contain 95.8% pure gold. It is very soft and not subject to corrosion alloys, so they do not keep polishing. Usually, this test metals used to make pendants and wedding rings.

Alloys of gold 999 samples

It contains almost 100% pure gold, that is, in fact, it is. This gold has been called of hearts. This is a very soft metal, prone to deformation, so now it is not used for making jewelry. While before the revolution of gold of 999 tests made ​​wedding rings. They were very thick and weighed more than 8 grams.

White gold - an alloy of gold with platinum, palladium or nickel. This is a very complex fusion. For example, if 1 g of gold 585 is composed of 58% pure gold and 42% silver and copper in equal amounts, then 1 g of white gold contains 28% silver, 17-18% of palladium or nickel, and 9% zinc and up to 16 % copper.

Pink and red gold is obtained by adding a copper alloy in the correct proportions to produce different colors.

While wearing jewelry contaminated, including gold. They appear plaque, which spoils the appearance of the product, making it dull and unattractive. A dirty, ear-rings can cause inflammation in people with sensitive earlobes, I'm not talking about the earrings for body piercing. Therefore, they must be cleaned regularly.

Then limp mud cleaned with a toothbrush. Can be washed at once, but then the remote sites will remain dirty. This is the flip side of the rocks under the clip, the inner side zipper, indentations, grooves, screws and so on. After maceration they raskisnut and easily they withdraw a soft bristle brush, without damaging the product. Next you need to be rinsed under running water and the product dried.
Carefully inspect the product, fully cleared it? You may need a second procedure of soaking.

Step 1

Chemical cleaning.

To remove oxidized elements on the surface of gold, you can use an ammonia solution. The interaction of ammonia with the compounds of copper oxide and silver leads to the formation of new, easily soluble in water compounds ammoniates. You need to buy at the pharmacy strong aqueous ammonia at least 25%. Pour it in a small jar and drop it into a product need to be cleaned. As for gold itself, and of its metals in pure ammonia is not valid, the processing time can not be limited, but early enough for 2-3 hours. You may want to leave at night, for loyalty and for heavily soiled items.
After a rinse under running water and dry.

- Toothpaste, select an ordinary white toothpaste (not a gel) with no bleaching effect.

- Take a soft damp cloth (old T-shirt fits) or a damp sponge and squeeze a little toothpaste on it. Gently wipe the silver in a straight line, moving back and forth. You can alternately wet silver product with water and apply toothpaste directly on its surface, then wet again and continue polishing. In any case, be very careful if you notice a scratch, stop and rinse pasta.

- When a cloth or sponge becomes dark from the raid, put toothpaste on a clean part and continue polishing.

- Rinse the product and warm (not hot) water and wipe with a soft towel.

- Baking soda. Baking soda can remove the unyielding cleaning deposit, but do not use it if you do not care what your product can suffer. Baking soda is an abrasive tool and it is not recommended for frequent cleaning of silver.

You can also wrap a flannel devices (there is a kind of flannel, specially created for this purpose). Pack the wrapped instruments in a sealed plastic bag. Regardless of the method of packing box nitrate, standing next to the product will prevent moisture and fogging. Never store silver next to the rubber, stainless steel or paint.

Why silver turns black?
This question interests of people first faced with the silver products. The answer is very simple. All this is mainly due to sulfur.

Mostly, this applies to silver we wear on the body. The man is such that sometimes sweating.

Along with then released sulfur and other reactive substances that interact with the silver and oxygen. As a result, silver products, formed a dark spot. A chemical release.

Esoterically-minded audience, argues that this slag out of the body and spoil silver jewelry.

Particularly sophisticated, say it is the devil's wiles. I think that all right, but the first - the chemical version is more credible. But still, if you have silver jewelry intensely dark, it is worth paying attention to their health or to the environment, it can (habitat) and the really hellish. It is recommended to pay attention to what we eat. It's no secret that today's foods contain large amounts of chemical additives. During the summer, we drink different beverages in large quantities and of their chemical elementy immediately withdrawn from then. Not surprisingly, the silver will turn black on the body very rapidly.

Why blackens the silver, with whom we do not have contacts, such as silverware, which we do not wear on his body, and only occasionally use for personal gain, such as silverware. These objects become darker, for the same reasons. However, sulfur and other free halogens (fluorine, chlorine, iodine, etc.), in this case are taken from the air. The air, he, you know this, in it, which just bullshit does not fly. Polishing silver, by the way, slows down the process of blackening.

If you dreamed of gold, that is mena you will be extremely successful. Do not attempt to judge the correctness of this interpretation, but in real life can be a gold key to success - financial. After all, investing in precious metals in successful circumstances can bring good income.

Few people know that there is a distinct culture of wearing of gold, the signs associated with the metal, as well as danger. To wear gold to learn, because it may help get rid of the disease or to bring down good luck on your head.

So moms, daughters, piercing their ears at an early age, without knowing it, give her an extra crumb invisible protection. Although there is another view that long to wear gold to young children is not recommended, because the metal - very strong and "loves" it, therefore people had already taken shape consciousness. What to believe - take your pick.

In order to bring us good luck gold, you should always carry in your pocket three gold coins. If this is not possible, you should send a normal coin in gold and wear it in your purse, but separately from the rest of the money.
