More than 2,500 tons of gold are mined throughout the world each year, according to Only Gold. All of the world's gold could fit in a 60-foot cube and would fill the space underneath the Eiffel Tower in Paris. The precious metal is part of the Earth's crust at an estimated .0025 parts per million. You also can find gold in seawater, but the concentrations are too small to profitably extract the metal. Jewelry enthusiasts often melt gold coins and jewelry to make unique jewelry.

1.Preheat your soldering tool to a temperature of 710 to 787 degrees Fahrenheit. Don't attempt the heating process until your tool reaches at least the minimum temperature because the gold will not melt.

2.Clean the gold ring with boric acid and water. Scrub gently with a brush. Rinse and dry the ring.

3.Remove all stones and non-gold clasps from the ring to ensure that the only material to be melted is gold.

4.Place the gold-plated ring into a vise. Ensure the ring fits tightly into the vise to avoid burning accidents.

5.Bring the soldering tool within 12 inches of the gold ring and continue heating the ring until it changes to the consistency of putty. Slowly move the soldering tool back and forth to evenly heat the gold.

6.Use jeweler's tools to form the ring to your desired shape. These intricate tools are specifically designed to handle melted gold.

7.Allow the gold to cool completely. Clean and polish the gold with a soft rag and a metal polishing compound.

Not all gold is made from pure gold. In some cases, a piece of jewelry contains metal covered with gold to imitate pure gold. This lowers the cost of producing gold, which lowers the price of buying gold. Real gold and gold-plated metals have characteristics that allow experts to distinguish them.

Gold Plating Process
Gold-plating involves an electrochemical process whereby jewelers place thin molecules of gold on a base metal like copper or brass. Some gold-plated products are not created using real gold, but something that has a gold color. The gold color is eventually worn down by pollutants and salts. Gold-plated jewelry lacks the durability of authentic gold jewelry.

Gold Mining
Miners remove gold from the earth and from water using various methods, including gold panning and dry washing. The extracted gold is either pure gold or has mercury and silver included. The gold must be refined so it has a market value. Miners can remove the mercury from the gold by heating it until it vaporizes. However, refiners must take steps to avoid inhaling the toxic mercury fumes. People later melt down gold into different forms, such as gold bars and coins.

Properties
Gold is non-magnetic. Gold-plated products sometimes contain magnetic metals like steel, which will be drawn to a magnet. Base metals also react to nitric acid, while gold will not. However, gold testers using nitric acid should know what they're doing, since the acid can seriously burn the skin.

Distinguishing
Jewelers cannot legally sell a product as gold unless it has at least 10 karats. However, without sophisticated tests, distinguishing between 10 and nine karat gold can be difficult. When seeking real gold, consumers should shop at stores that have quality assurance programs and test their pieces. In addition, gold that has poor quality workmanship is likely to be gold-plated instead of pure gold.

1.First thing is to prepare surface to be plated. Place magnetic apron around surface, so run off will go in desired container. Start off with a polish for metals. Any metal polish will work. After polishing hook the ground wire from plater to the metal piece. Pour your Activator in a plastic cup and dip electrode with cloth wand into Activator. Rub entire surface until satisfied that no contaminants remain. Rinse with water.

2.Rinse out wand and pour Chrome plate solution into new cup. Dip clean wand into solution and rub over entire surface like you did with the Activator. You will have to change settings on plater. Finished surface should have a highly reflective finish. Rinse with water.

3.Rinse wand out again. Use same cup of Activator for this process. Dip wand into Activator and rub over entire surface. You will see no effect to the Chrome shine, because all your are doing is cleaning it. Once satisfied of coverage rinse surface and wand off with water.
