Libyan Desert Glass
Libyan Desert Glass, also known as Libyan Gold Tektite, is a rare and ancient tektite that formed approximately 29 million years ago. Tektites are a natural glass that form when a meteorite strikes the Earth’s surface; melting and vaporizing the surrounding rock, when it cools it forms glass. Libyan Desert Glass is found in one of the most isolated and barren parts of the world, scattered across the eastern Sahara Desert in Egypt and Libya. The Sahara Desert is the hottest and largest desert in the world; spanning over 3.6 million square miles (9.2 million square kilometers).
