Figure 17 from the 1915 volume The Rare Earth Industry depicting a machine (1/14 actual size) for burning off and hardening inverted mantles, a component of incandescent gas lanterns. The volume details various industrial applications of rare earths and closely-related elements, including thorium, zirconium, tantalum, and tungsten. Particular attention is given to the illuminating effect of the oxides of thorium and cerium and their application to the manufacture of incandescent gas mantles and electric lamps. The volume also includes chapters on uranium and vanadium, as well as the industry of radioactive substances.
