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.
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.
The globe is the outer glass shell. The shaped coil inside is the filament. Wires and the stem support the filament inside the bulb. There are gases within the light bulb to prevent it from burning out. And the base is to securely support the bulb.
A light bulb is made out of three items. A filament produces the light, glass gives the light bulb shape and controls the brightness, and the base allows the bulb to be placed in a socket.
The parts of a light bulb are the glass envelope, mixture of inert gases at a lower pressure, and a screw cap. Inside of the light bulb is the coiled tungsten filament, support wires, glass fuse enclosure, connecting wires, and the electrical contact.

Nothing, glass is an insulator.
Because inside of the glass bulb lies a vacuum that prevents the bulb from burning out within a few seconds rather than several thousand hours.
