Answer . It happens with exposure to air and certain chemicals. The silver atoms combine with oxygen to form a layer of silver oxide, which is what causes the discolorat…ion. . See Related Links . See the Related Links for "How to clean and polish silver" to the bottom for the answer.
Silver tarnishes from reacting with Oxygen in the air (The stuff we breathe, if you don't know, I highly doubt you don't know) thus forming tarnish.
yes, I believe its the addition of oxygen to silver.
Platinum over silver will not tarnish. Platinum is a very quality type of metal. Platinum is very pricy but will last for a long time.
yes it can tarnish very well if not protected
When silver is combined with sulfur, it forms a layer of black silver sulfide. Being exposed to air and sulfur will cause any type of silver to tarnish.
Yes, it happens, unfortunately.
Silver tarnish occurs when silver turns black, caused by oxidation when it is exposed to the air. Tarnish can be removed by rubbing the silver with polish and a soft cloth….
The tarnishing of silver is a chemical reaction in which oxygen and hydrogen sulfide in the air is reacting with (oxidizing) metallic silver to form silver sulfide, Ag2S. This… reaction is dependent upon moisture, and occurs much more rapidly under humid conditions.
Good question! I know that there are so many different things that can tarnish silver. I believe the main cause for tarnishing silver is sulfur that is found in many lot…ions and cleaners. To clean the tarnish, you can go to the JIC (Jewelry Information Center) website at www.jic.org to get info on now to take care of your favorite silver items, as well as plenty of other materials. They have everything you can possibly need to know about jewelry and they host a ton of really fab gift ideas... Also, dont forget to visit the jewelry stories section where people (including me!) contribute their own personal jewelry story for others to read. And feel free to add your own so others are able to read it and feel inspired! I think what's so great about this section is that you get to see how people have come to cherished certain pieces of jewelry so much.. whether they be items purchased for themselves or by others. Plus, if you submit a story, you're entered into the JIC Sweepstakes to win a beautiful Kay Jeweler's white gold diamond necklace! www.jic.org Good luck, Laur
why silver jewellery tarnish with lime?
I have a nickel silver chain that was sold as sterling silver in 1991 (it is stamped "ster"). However it is turning a bluish color. Sterling silver first turns a yellowish col…or and then goes black. I think a number of my recently purchased "ster" or "925" chains are actually nickel silver, which doesn't contain any silver at all (60% copper, 20% nickel, 20% zinc according to wickipedia). I am horrified at the widespread metal fraud that has been and is being committed. Check out "aluminum bronze", especially all of the images, to protect yourself against yellow gold fraud.
Silver tarnish is silver that has reacted with the air to form Silver Oxide, AgO, under certain conditions, and it is black in color. Silver Nitrate, AgNO3, has been used to d…evelop photographic pictures, years ago. Now it has been replaced with other chemicals. In the old days, a Photographer who used to develop pictures, when done, would go outside into the sunlight and his arms would instantly turn black. You've probably seen old pictures of this. There are cleaners out there that will remove the tarnish, though the silver may never look the same as it did. For this reason, cleaning collectible silver coins will instantly cause their value to diminish or even become worthless - the color of the silver has changed, there is minute scratches on the surface of the coin, and Coin Dealers don't like them - the coin has lost its eye appeal.
Tarnish occurs when silver reacts with oxygen or hydrogen sulfide in the air, moisture, skin oil from being handled, and other contaminants.
Yes, it does. Any silver or silver plate item will oxidise if it exposed to the atmosphere and not polished regularly. But cutlery or other items that can be wrapped in tiss…ue paper and put away or that can be put back into the special baize lined oak or mahogany case that it came in will tarnish much more slowly. Yes, after then， the color would turn into dark.
sterling silver is 97.5% pure silver and7.5 copper alloy. This copper alloy reacts to humid conditions and acidic skin by tarnishing (brown) and oxiding (black).Lime is ve…ry acidic fruit so copper in the silver is reacting to the acid in the lime and tarnishing or oxiding.Clean it as soon as possible with polishing cloth.
