  • In 1898, after laboriously isolating various substances by successive chemical reactions and crystallizations of the products, which they then tested for their ability to ionize air, the Curies announced the discovery of polonium, and then of radium salts weighing about 0.1 gram that had been derived from tons of uranium ore.

  • In other ion-based dryers, I'm told, the Tourmaline is sprayed on the barrel of the dryer, Soon enough, hot air wears that coating down, and the dryer loses its special powers --- that is, its ability to ionize the hot air.
