Oxidized silver is silver that has been exposed to oxygen in a pressurized environment for a long period of time. It is different from traditional silver because it is a darker color and has very little luster.Know More
Pure silver must generally be polished and cleaned on a regular basis to keep it from becoming tarnished. It should not be placed in areas where it will be exposed to large amounts of oxygen and should be taken care of in special silver storage containers. Oxidized silver will not be affected by the tarnish and the tarnish will allow the silver to take on a more oxidized work. Oxidized silver does not have to be polished or cleaned and can generally be left in any type of environment.
Pure silver is found only in the ground and is not combined with other elements to make pieces of jewelry or home decor items. It is the most reactive silver and will tarnish more quickly. Sterling silver is the most popular and common type of silver found in jewelry and home decor. It is combined with other metals to help prevent it from tarnishing. Sterling silver is much harder than pure silver and is able to stand up to daily use.Learn More
The fire triangle is composed of oxygen, heat and fuel. It is sometimes called the fire tetrahedron because of a fourth component, chemical reactions. Fires start with just the first three elements, but they cannot remain burning without the heat produced through chemical reactions.Full Answer >
The density of pure silver is 10.5 grams per cubic centimeter. However, the density of most silver found in nature usually ranges from 10 to 12 grams per cubic centimeter.Full Answer >
Sterling silver is made of 92.5 percent pure silver and 7.5 percent of another metal. The other metal that is added to silver is typically copper, but zinc, platinum and germanium are also used in making sterling silver.Full Answer >
Silver is found embedded in several different minerals, namely copper, zinc and lead, and the refining process varies depending on the source. Silver derived from copper and its derivatives, including copper sulfide, requires different handling and refining techniques than silver minerals taken from zinc deposits and lead sources. These metals have different physical properties, which accounts for the different methods needed for proper extraction.Full Answer >
