Lighting Flint
In 1903 von Welsbach won another patent for a fire striker ("flint") composition named ferrocerium. Welsbach's flints consisted of pyrophoric alloys, 70% cerium and 30% iron, which when scratched or struck would give off sparks. This system remains in wide use in cigarette lighters today. In 1907 he formed Treibacher Chemische Werke GesmbH to build and market the devices. In 1920 he received the Siemens-Ring as his name had become a synonym for the rise of artificial lightning.
Over the rest of his life he turned again to "pure" chemistry and published a number of papers on chemical separation and spectroscopy. He presented a major paper on his work on the separation of radioactive elements in 1922.

Famous quotes containing the words lighting and/or flint:
“No one after lighting a lamp puts it under the bushel basket, but on the lampstand, and it gives light to all in the house. In the same way, let your light shine before others, so that they may see your good works and give glory to your Father in heaven.”
—Bible: New Testament, Matthew 5:15,16.
“O sovereign mistress of true melancholy,
The poisonous damp of night disponge upon me,
That life, a very rebel to my will,
May hang no longer on me. Throw my heart
Against the flint and hardness of my fault,
Which, being dried with grief, will break to powder
And finish all foul thoughts. O Antony,
Nobler than my revolt is infamous,
Forgive me in thine own particular,
But let the world rank me in register
A master-leaver and a fugitive.”
—William Shakespeare (1564–1616)
