Lybian glass

Lybian desert glass, 29 million years ago was probably formed when an asteroid or comet hit the surface of the earth like a huge atomic bomb

Lybian Desert glass is found between the towering dunes of the Eastern Great Sand Sea of Egypt where bedrock is exposed. Lybian Desert glass is the remaining evidence of a violent asteroid or comet impact with Earth.

According to today's scientific knowledge this in a pale yellow to green shining impact glass emerged from a collision of a meteorite with earth about 28,5 Mio years ago. In the glowing heat sand melted, splashed up in the air and spread over a 4000 square kilometers sized area in West Egypt. Like with sand, the essential constituent is silicium dioxide, a possible hint of iridium is a indicator for the extraterrestrial origin.

During the neolithic time, about 10000 years ago, men discovered this glass. It was used as a substitute for flintstone, one can find artefacts formed as sharp blades and graters.
The old Egyptians found a less pragmatic application for this special stone. Even in those times it was considered to be precious and so it become part of religious objects like Tutenkhamon's amulet, there as a carved scarab.

Lybian Glass is a natural glass composed of 98 % pure silica. Chemical analyses have shown that the glass is locally enriched in meteoritic elements.
