What is a Light Bulb Made of
Light bulbs are made of either hard glass or soft glass depending on the temperature of the bulb. Hard glass helps prevent breakage due to heat and moisture. Look here for more information: http://www.goodmart.com/facts/light_bulbs/incan_diagram.aspx
There are three basic parts that make up incandescent light bulbs which are the filament, the glass bulb and the base. Depending on the use of the light bulb it could vary in size and wattage.
well, you have the glass on the outside and then a bunch of wires on the inside the wires are attached to a little light on the inside, there is a battery in the light bulb that makes it turn on, so you switch the light on and it goes on.
