Thanks for the post! Looked through the photos, impressive! Browsed a search engine a little, only found a couple on topic pages out of many. It would make sense lightning charges these crystals in a special way.

Found this artical about Lodestone istp.gsfc.nasa.gov/earthmag/lodeston.htm

"Dr. Wasilewski believes that is what happens when a chunk of the appropriate ore is struck by lightning. Lightning is a discharge of cloud electricity, a large electric current lasting just a fraction of a second, but during that time it produces a strong transient magnetic field.

The idea was tested at a unique facility of the New Mexico Institute of Technology, the Langmuir laboratory. That lab, a center of lightning studies, was built on top of South Baldy Mountain near Soccorro, New Mexico, the location of frequent lightning strikes. By placing mineral samples where lightning would hit them, Dr. Wasilewski turned magnetite with appropriate crystalline structure into lodestones."

Now days it seems like the norm to direct lightning into the ground by a copper ground rod, if this energy from nature could be directed into transformers and storage cells maybe it could be used as a source of energy.

Thats interesting, I've never heard of fulgurites. I like the quartz I fired because it's like it has a little of the fire energy in there, especially noticable in rays of the sun.
