We are going to get techy here, we are going to talk about the element Tungsten, present nearer than you think.
Tungsten is found naturally on Earth almost exclusively in chemical compounds. It's most common application is in the incandescent light bulbs used before LED technology arrived. The reason why tungsten was the favorite metal to work with when producing light bulbs is because it's extreme resistance to high temperatures. The part of tungsten that lives inside a Light bulb is called "filament" and is of what that tiny spring inside of a light bulb is made of. The melting point of tungsten is 2770°C.
Tungsten is also used in applications in which extreme hardness and heat resistance is needed. But also, tungsten is not just exclusive of the industrial world. Tungsten has become a choice for jewelry when it comes to rings and other goodies. Because of tungsten carbide's hardness, rings made of this material are extremely abrasion resistant, and will hold a burnished finish longer than rings made of metallic tungsten.
Tungsten is really rare, and it has been known in the homeopathic world to be a good friend for human health as an excellent painkiller and inner balance tool.
