Light bulbs are comprised of a number of nonmetallic minerals and metallic minerals, as well as various other periodic gases and nonmineral materials. Many of these minerals are found in abundance in nature and in the human body. Most minerals must be mined from rock or from the earth's soil. Minerals are used in light bulbs to make the glass, the mechanism that allows it to light and the fuel to generate the electricity.
1. Copper
o Copper is a metallic mineral substance, and is used in the production of electric light bulbs because it conducts electricity very well. Copper,along with nickel, is used to make the wires that lead into the main body of the bulb. These wires carry electricity from an electric source to the area that emits light, called the filament. Copper must be mined, and is found in nature in several different forms, such as azurite, malachite and cuprite.
Aluminum
o Aluminum is a metallic mineral found in abundance in the earth's crust, and according Georgia State University's Department of Physics and Astronomy, aluminum is the third most abundant element found on earth. Aluminum is refined from bauxite ore, and is a good conductor of electricity. Aluminum is used to create the heat deflector in the light bulb so that hot gases do not build up and break the bulb.
Nickel
o Nickel is a metallic white mineral used in light bulbs, because it does not corrode. Also, when mixed with iron, nickel creates an alloy that is used to make the inner stem wiring of the bulb. Nickel is used, along with manganese and copper, to make the fuse of the light bulb. A nickel-copper alloy is also used to make some of the light bulb's electrical wiring.
Molybdenum
o Molybdenum is used to make the support wires for the filament in light bulbs. Molybdenum is a metallic mineral that occurs naturally in the earth's crust and in the oceans. It is very hard and because of this, it is used in tool-steel alloys. Molybdenum is also used in light bulbs because it does not melt easily. Molybdenum is usually found with other minerals in powellite and wulfenite.
Trona
o Trona, also known as soda ash, is an evaporite mineral. This means the mineral forms as the result of evaporated water or liquid or through the process of erosion from rock. Along with salt, lime and coal, trona is used to make the glass bulb of the light bulb. Trona is sodium carbonate, and is found in bodies of water that contain soda brine. Trona byproducts include baking soda, some preservatives and some detergents and soaps.

What machine was used to make light bulbs?
A machine is any device that uses energy to perform some activity.
What chemical element other than fluorine is used in some light bulbs?
sodium is used in street lights,thats why they have a yellowish/orange colour Answer: Neon & Argon are used in light bulbs.
What are red light bulbs used for?
To make red light.
How does cotton help make a light bulb?
Cotton is not used in light bulbs.
What are the names of minerals used to make a light bulb?
There are many sorts of light bulb these will have different components and therefore minerals.However here are some elements/minerals used in their manufacture:Tungsten,QuartsNitrogenIronMercuryPhosphorousSiliconGermaniumChromeLeadTinCopperAluminumIf your referring to florescent lamps the coating is usually phosphor based. This mineral will absorb ultra-violet light and re emit it in the visible spectrum. The insides of standard lamps are sometimes coated with a light-diffusing mineral such as talc.
The element used in light bulbs?
Argon(or nitrogen) and tungsten are used in incandescent light bulbs.
What are domestic light bulbs?
Domestic light bulbs are simply the light bulbs (usually of the filament type) used in the home.
How many minerals are used to make a light?
5 minerals are usedThe minerals are - 1. Copper2. Aluminium3. Nickel4. Molybdenum5. Trona
What metal use the filaments in light bulbs?
Tungsten is used in filaments of light bulbs.
When did light bulbs start using watts?
Light bulbs have always used watts.
Can CFL light bulbs be used in recessed lighting?
Yes, CFL light bulbs can be used in recessed lighting.
Is tungsten carbide valuable?
A little bit, as it is used to make light bulbs and other electronics.
How efficient are commercial light bulbs compared to industrial light bulbs?
Industrial light bulbs typically have larger wattage than commercial light bulbs. This is because commercial light bulbs are more commonly used in public as opposed to private homes.
Can copper be used to make filament of bulbs?
Yes, copper can be used to make the filament in bulbs. Copper is a good conductor of electricity and can withstand high temperatures, making it suitable for use in light bulb filaments.
