Uses of Gold

Gold is the most useful mineral on the planet thanks to its variable properties. The luster has led to its use as jewelry. The metal can also be alloyed, pressed into thin sheets and wire drawn. The following are just some of the many uses of gold.
Gold Leaf and Gliding
When the metal is pressed into thin sheets (called gold leafs), it can be set on odd picture frame surfaces. Gliding can also be applied on furniture and molding. This practice is very common. It’s possible because the metal is malleable. It is the only mineral that can be flattened to thousands of an inch thick.
Making Glass
Gold is also used in creation of glass, usually as a pigment. Typically, a small quantity is dangled in glass as it is annealed. The end result is a vivid ruby hue. Some companies use the metal to make specialty glass for climate controlled complexes. The process varies.
But generally a small quantity is scattered in the glass. Solar radiation is directed out, keeping heat out and the interior cool. The reverse happens during the winter. Heat is projected into the building, keeping it warm. Sometimes the metal is coated in the glass rather than dispersed. The result is the same.
For Trophies and Crowns
Since time immemorial gold has been applied for crowns worn by royals. It’s the metal used for trophies and awards. The expression “gold standard” is equivalent to excellence of the highest form.
Usage in Space Technology
Gold is malleable but it is very dependable. That’s why it is used by
NASA in their space shuttles. The metal is used in circuitry as a connector and conductor. Gold layered polyester film is applied in spacecraft. It assists in temperature stabilization and infrared radiation reflection. If this isn’t used, heat will build up on the craft’s dark colored areas.
Usage as Jewelry
This metal has been utilized as jewelry since the time of the ancient Egyptians. Today gold is still used the same way. Nearly 80% of all recycled or mined gold is intended for ornamental use. The biggest producer in 2011 was China at 355 metric tons followed by Australia with 270. The United States is third at 237 metric tons. People can buy and sell gold. There are many watch buyer Sydney in the world who buy and sell watch.

This metal also functions as a lubricant for craft components. Standard lubricants can’t be used in space due to radiation. The molecular structure of gold, plus its shear strength makes them suitable. An astronaut’s helmet visor has gold film. The film protects an astronaut’s skin and eyes.
