What is a Fulgurite?
When lightning strikes the sand at a temperature of at least 3,270 degrees, the heat melts the silica and fuses the sand into fascinating structures. This takes place within the time frame of one second. The long, slender, hollow glass tubes are below the surface of the sand and can be found by looking for uneven coloring on the sand's surface where the lightning has entered. The glass structure is usually an irregular shape and can be transparent white, black or tan. They are very delicate in nature and are sometimes used in making jewelry.
The very brittle fulgurites break easily while removing them from the sand. Each fulgurite is different and can have a main branch and then many smaller branches that resemble the actual flash of lightning. Some fulgurites are round and hollow while others are flattened into rough shapes caused by the pressure of the sand.
Fulgurites are used by some people as a tool for prayer and meditation. It is said to arouse energy and help one focus.
