Fulgurites
The Fulgurites are glass tubes formed in quartzose sand, silica, or soil which are made by lightning strikes. The Fulgurite is the name in Latin and word Fulgur means lightning. They have many shapes, size, and colorations depending on the material being fused by the lightning strike.
The fulgurites from Algeria are interesting because they are mostly solid and made of the sand which hit by lightning. they contain glassy silica (quartz) and mineral (Lechatelierite). The surface of fulgurites are very rough but they have beauty shapes.

Peak temperatures are estimated to reach 30,000 degrees K - sufficient to melt the sand to form natural glass tubes. This fulgurite was collected in the Sahara Desert in the Grand Erg Occidental, Algeria.
