Argon
Tungsten in the filament of incandescent lightbulb.
There are a few factors of Thomas Edison designing a light bulb. The main factor was finding a metal that would glow without it burning.
No, pig hair is not used to make light bulbs. Light bulbs are typically made using a combination of glass, metal, and tungsten or other types of filaments. Pig hair is not a suitable material for this purpose.
The vacuum pump was the critical precursor to the invention of the hot-filament light bulb. Indeed, improvements in vacuum pumps have continuously resulted in improvements in incandescent light bulbs. And of course, such things as metal working, glass working etc.
Incandescent light bulbs use tungsten( a metal which can withstand very high temperatures) as filament.When heated to a very high temperature, the filament glows emitting light and heat. Heating effect in filaments is caused by the property of resistance in conductors. On reducing the cross- section area( thickness) of the filament, its resistance is increased and hence the filament glows with comparitively lesser electric current.
Argon
Modern light bulbs contain no gases whatsoever; a vacuum.

It is not a gas, but a vacuum. This keeps the element (wire) from burning up. No oxygen means it can stay hot longer.
Any inert gas, such as helium, argon or xenon
Tungsten is used in filaments of light bulbs.
The type of metal that is used in domestic light bulbs is known as tungsten. This is the metal that is usually found in incandescent light bulbs.
