if you don't know about the inventing of lightbuld heres how its made. a piece of metal string gets shocked with electricityand burns and glow. this is similar to fire. Fire needs to have air to burn with out it cant burn. The glass holds in specials type of gases. Neon in a light build will make it go neon red. Krypton gas will glow blue and argon a light yellow glow. the glass holds the gases in to stop it from escapes. the filament (pieces of metal wire) burns better in a special kinds of gases as mentioned above.

Thomas did NOT make the light bulb. He made a safer impression of it.

Tube, bulb, envelope, globe.
The glass bulb of a light bulb is known as the globe. It is made from a thin layer of glass to ensure light efficiency and still support the rest of the bulb.
Electricity + Glass = Light bulb

Glass is the insulator in a light bulb. The base has a heavy piece of glass to separate the ring from the center, and there is a glass support inside the bulb to hold up the filament and separate the wires going to the filament.
A conventional light bulb consists of glass, metal, and gas, but no oil
Nothing, glass is an insulator.
