FIRST ADVANCEMENT As time progressed more and more people jumped on the incandescent light bandwagon. Edison and many other aspiring inventors across the globe conducted many more experiments in an attempt to improve the light. The next big step came in the early 1900's when the carbon thread filament was replaced with a tungsten filament. Tungsten had been tested and proved to work better because it has a lower melting point than carbon and evaporates slower extending the life of the bulb. However, due to the brittleness and lack of ductility in tungsten many unsuspected problems arose. Then in 1913(?) it was proven that fused tungsten could be rolled at very high temperatures by following precise steps (which we will not be getting into).
