A Gas Mantle is a device that gives of considerable light when heated. The name refers to its original power source, existing gaslights, which filled the streets of Europe and North America in the late 19th Century mantle, referring to the way it hung above the flame. Gas Mantles are still being used in Uttar Pradesh and Bihar in India, Afghanistan, Pakistan and Bangladesh. The gas mantle was one of the many inventions of Auer von Welsbach, a chemist who studied rare earth element in 1880. His first process used a mixture of 60% Magnesium Oxide, 20% Lanthanum Oxide and 20% Yttrium Oxide, which he called Actinophor. To produce a mantle guncotton is impregnated with the mixture and then heated, the cotton burns away leaving a solid, but fragile mesh of ash. These original mantles gave off a green tinted light and were not very successful, and his first company formed to sell them failed in 1889. A new mixture of 99% Thorium Oxide and 1% Cerium Oxide gave off much whiter light, and after introducing it commercially in 1892 it quickly spread through out Europe. The gas mantle remained an important part of street lighting until the wide spread of electric lighting in early 1900. A mantle is basically a small sock made of silk or asbestos. Asbestos can withstand high temperatures, but is also toxic. Silk-based mantles are extremely brittle once first burnt and must be replaced frequently. Thorium is radioactive, and Pure Thorium becomes more radioactive as it ages owing to its...
