Explanation:
While this little bit of tungsten residue is annoying for modern people who like to read at night, in the early 1900s light bulbs used to burn out their filaments and turn black very quickly. Then in 1913, the American chemist Irving Langmuir figured out a surprising solution to keep bulbs burning bright: fill the bulb with an inert, non-toxic gas called argon. Before Langmuir, manufacturers made light bulbs with a vacuum inside to prevent oxygen from contacting the filament. This was because when current ran through the filament, it heated to 3,000°C—hot enough to oxidize the metal in the filament. While this temperature helpfully caused the filament to radiate visible light, it occasionally caused a tungsten atom to sublime (change directly from solid to gas phase) off the filament and onto the bulb’s glass, deteriorating the filament and blackening the bulb.
