Thomas Edison is issued two patents. (US No. 490,953 -4) The first patent is described as the “Art of Generating Electricity” for a cell made with positive and negative electrodes in a heated chamber containing dry chemicals which are sufficiently exhausted for the gases generated to become good electrical conductors. The second patent is described as the “Manufacture of Carbon Filaments for Electric Lamps.” In it, Edison describes the process of heating vegetable fibers, such as bamboo, in a furnace until the fibers are carbonized, before soaking them in a sugar syrup to fill the material’s pores before reheating them until they are wholly carbonized. This process is fundamental to the creation of incandescent bulbs.
