Descripción

Locality: Great Sand Sea, New Valley Governorate, Egypt

Description: This glass was made in a few seconds of extreme heat about 29 million years ago. Libyan Desert Glass is almost pure silica. It lies in the corridors between dunes in the southwestern Great Sand Sea of western Egypt, near the Libyan border, scattered over an area of roughly 2,500 to 6,000 square kilometres.

For decades scientists argued about how it formed. Ideas ranged from lunar volcanoes to a meteor exploding in the air. In 2019, researchers found zircon grains in the glass that had once been reidite, a mineral that forms only under shock pressures of about 30 gigapascals. That same year, shocked quartz turned up in the local bedrock. Together these point to a real meteorite impact. No crater has ever been found, and it may have eroded away or be hidden under the dunes.

An Egyptian Desert Survey expedition led by Patrick Clayton found the glass on 29 December 1932, and Clayton and Leonard Spencer of the British Museum described it in 1934. People had found it long before that. The yellow scarab at the centre of a pectoral from Tutankhamun's tomb is carved from Libyan Desert Glass.

About 1,400 tonnes of the glass are estimated to survive. Pieces are typically strongly wind-eroded from millions of years in the open desert. This one weighs 175 g.

In crystal traditions, Libyan Desert Glass is associated with transformation and manifestation.
