Acheson began his career as a surveying assistant for the Pittsburgh Southern Railroad.
In 1884, Acheson left Edison and became supervisor at a plant competing to manufacture electric lamps. He began working on the development of Cubic Zirconium (artificial diamonds) It was here he began his own experiments on methods for producing artificial diamonds in an electric furnace. He heated a mixture of clay and coke in an iron bowl with a carbon arc light and found some shiny, hexagonal crystals (silicon carbide) attached to the carbon electrode.
In 1891 Acheson built an...
