3 inch Fulgurite from Augusta, GA. What's a "Fulgurite"? This fulgurites is from a sandpit in Augusta, GA. It site high above the other land. It attracts many lightening strikes a year. This shows what happens when LIGHTNING strikes SAND !! "Fulgurite" means "lightning" in Latin. Each flash of lightning releases an average energy of 1 billion Joules. Air temp may reach 10,000 - 30,000 degrees K., with currents from 10-100KA for microseconds. It vaporizes sand and rock to make amorphous glass. Tubular fulgurites may reach over 8 meters, but are fragile. What an interesting thing to add to your rock & mineral collection! We make them very affordable, though smaller...most still have a hole where the lightning went through. We also have the world record fulgurite. Posted with eBay Mobile
