Transcript: White gold is never pure gold. It is usually 10K (which is 41.7% pure) or 14K (which is 58.3% pure). Pure gold is always yellow. 'White' gold is gold alloyed with a white metal, usually silver. Gold-nickel alloys are strong and hard and are often used for pins and rings Copper may be added for improvement in malleability. Gold-palladium silver and gold-nickel copper zinc are used in the jewelry industry. Nickel and palladium behave as primary bleaching agents for gold and zinc behaves as a secondary bleaching agent to improve the color of copper. well white gold is made for mostly for Jewelry like engagement rings and wedding rings White gold White gold is an alloy of gold and at least one white metal, usually nickel, manganese or palladium. Like yellow gold, the purity of white gold is given in karats. A common white gold formulation consists of 90% gold and 10% nickel.Copper can be added to increase malleability. The chemical properties what it's use for ? where it's produced/manufactured one interesting fact where was it discovered ? physical properties how much does white gold cost ? Gold itself is a pure element and is naturally yellow. It is also soft, too soft to hold up in jewelry. so we need to mix with other metals to make it harder and more rigid for use in jewelry White gold is actually yellow gold which has been combined with a white metal such as palladium or nickel to give it a white hue. white gold If you’re wondering how white gold is made, the first thing to understand is that white gold is an alloy a white variety of gold doesn’t exist in nature. Metals that are naturally white are combined with gold to give it an appearance that’s more like silver. White Gold

Transcript: One thing cotton caused too is for more people to join the Underground Railroad and help slaves escape. Image by Tom Mooring After Lincoln became president, the south tried to become it's own country and split away from the US, Lincoln didn't want that to happen so the north and the south went to a war with themselves that was considered the bloodiest war in american history. White Gold Chaz Ellis The Middle There were also many things created for cotton making, one of the most successful one being the cotton gin, it was able to take the seeds out of the cotton much faster than by hand which also caused the slave rate to go down a bit, but not to make that much of a difference. Cotton also caused a lot of controversy in the north since the north wasn't so keen on slavery, some of the people in the north even tried too free the slaves but died since none of the slaves wanted to join the battle which was their goal to get the slaves fighting. Cotton was also one of the main sources of income in the south which is one of the reasons why they didn't want slavery to stop since they helped them with their income of money and the reason why they didn't want Lincoln to become president. But because of the increase demand on cotton, slavery was also increased so farmers could pick the cotton faster and have it shipped out faster, but even if the farm owner has so many slaves it took at least 5 hours to create one pound of seedless cotton. Cotton has been with humanity for thousands of years, but wasn't used to for so many things until the 19th century where it grew popular in clothe making. The beginning The civil war lasted for 4 years until the north won the war and was able to keep the south apart of the US, one major mistake the south had in the war was that they thought Britain would help them in this war, but the anti-slavery group in Britain won and did not help the south which costed the south the war. The End

Transcript: Work Cited White gold is used in the making of jewelry and they make less white gold with nickel because one out of eight people would get a skin rash from the jewelry. White gold properties. White gold was first introduced in the 1920's. It was achieved by adding alloys to yellow gold, such as nickel, palladium, platinum, and zinc. It was introduced as an affordable platinum substitute for engagement and wedding rings. The basic unit of weight used in dealing with gold is the troy ounce. One troy ounce is equivalent to 20 troy pennyweights. In the jewelry industry, the common unit of measure is the pennyweight dwt. which is equivalent to 1.555 grams. The properties of white gold, including its color, depend on its composition. Although most people think white gold is a shiny white metal, that color is actually from the rhodium metal plating that is applied to all white gold jewelry. Without the rhodium coating, white gold might be gray, dull brown, or even pale pink. http://ringoblog.com http://www.usagold.com/reference/properties.html http://www.zales.com/jewelry101/index.jsp?page=metals_WhiteGold http://www.thediamondbuyingguide.com/preciousmetalsguide-gold.html http://chemistry.about.com/od/jewelrychemistry/a/White-Gold photo credit Nasa / Goddard Space Flight Center / Reto Stöckli Instead of copper and silver used in yellow gold, white gold contains such metals as nickel, zinc, or even platinum.

White Gold is an alloy made of at least one white metal, usually nickel, silver, Rhodium, manganese, and palladium etc. A common white gold consists of 90 wt.% gold and 10 wt.% nickel. White gold comes in many purity percentages – 10K is 41% pure gold, 14K is 58% pure gold and 18K is 75% pure gold, and the rest another white metal White metal can be 25% up to 59% Many time can be more than one metal; 75% gold, 16% silver and 9% copper yields yellow gold. White gold is an alloy of 75% gold, 4% silver, 4% copper and 17% palladium. Mostly used in jewelry especially bridal jewelery Used to enhance diamonds and other precious gemstones Can also be used for other accessories like belts and grillz, medals, artwork, etc. Even a Benz The Belais brothers began experimenting with formulas for white gold as a substitute for platinum in 1887 by adding alloys to yellow gold, such as nickel, palladium, platinum, and zinc Patented in 1920 by the Belais brothers It was a cheaper alternative to platinum, but a stronger alternative to silver. Jennifer Sanchez Period 5 Due: 5/27/15 My Alloy: Interesting facts Cost of White Gold Mostly manufactured in jewelry Can be manufactured in medals, accessories, artwork etc. White gold is manufactured by alloying other metals with yellow gold. Most commercial alloys are zinc, silver, gold, nickel, and platinum produces the whitening or "bleaching" effect to gold Manufacturers avoid nickel white gold, since alloys made without nickel are less allergenic The price of White Gold depends on which metals have been used to make it. Palladium and platinum are the high value metals, if made with silver or nickle the value is much less Palladium white gold and strand white gold: Average $100-$1,000 Can range from $50-$2,500 Uses of White Gold White Gold White Gold Chemical Properties: Usually 90% gold 10% metal Copper sometimes added for improvement in malleability Nickel and palladium behave as primary bleaching for gold and the copper Rhodium metal plating gives it more color Chemical & Physical Properties
