A shiny, silvery white, very dense transition metal which has a very high melting point. It is easily drawn into wire and is used in light bulb filaments.
 Cylinder Cylinder.
Tungsten is a wonderfully dense metal. Compare the weight of this 1 kg cylinder with the similarly sized piece of magnesium four cubes left and three cubes up. Tungsten is over 11 times denser and there are few people who do not give a smile in surprise when lifting it for the first time.

 Light bulb Light bulb.
This projector bulb has a larger, more easily visible filament than typical incandescent bulbs, but other than that it is no different than the ones still common in homes. All such bulbs are horribly inefficient, however, and will eventually be entirely replaced by compact fluorescent or LED lighting, except possibly in situations requiring very compact, bright sources, such as projectors.

Its color varies from colorless, through white, pale yellow, brownish yellow, reddish yellow, orange to pink and is translucent to transparent. Usually massive or disseminated, it also forms pseudo-octahedral crystals.
