Answer:
Filaments are made up mostly of tungsten, a metal. The resistance of the filament heats the bulb up. Eventually the filament gets so hot that it glows, producing light. ... so to store this gases in bulb a glass coatings are used. Also the glass is non reactive with glasses,hence the glass are used to electric bulb.
