HERTZITE & URALIUM CRYSTALS, 1920's

Crystals were used in assemblies for the detection or demodulation of radio waves, in early crystal sets. See Item A1318 The term Uralium is just as it says on the tin a trade name and the type of composition of the crystal is possibly Iron Pyrite or Galena. The same could be said of Hertzite. See Items A1494. The tin of Uralium also contains a spare wire coil known as a ''Cats Whisker''. Uralium is listed as a supposed new metallic element announced in 1879, its existence has not been confirmed.
