The main problem was finding a filament—a thin fiber or wire—that would heat to a bright glow when electric current passed through it, but would not melt. Edison tried thousands of materials, from platinum to twine to human hair. Finally, around 1879, he tried bamboo fibers that he had pulled from a Japanese fan. After carbonization—the process of converting a fiber to pure carbon—the bamboo filament burned and burned without melting. Edison finally had his light bulb.
