Libyan Desert Glass (LDG)
Formed by a massive impact near the Libyan border with Egypt 26 million years ago, this impactite is one of the most sought after type. Some glass have white formations called cristobalites that are polymorphic formations of silicce at very high temperature. Dark parts or completely dark parts that after chemical analysis indicate parts of meteor inclusions. Therefore, the best explanation for the formation of this glass is that of a large meteor impact that melted the silicon-rich earth around it. They can have aerodynamic features similar to meteorites as a result of being thrown into the air in a molten state.
LDG is a glass of natural composition formed purely by silica, giving it the label of the purest glass in the world with 98 wt%. This purity gives it unique qualities. It can be heated to temperatures of up to 1700 degrees before it melts. This composition has long been studied and regarded as mystical.
Ancient Egyptians already knew about these rocks, and they picked them up and used them to make tools and jewelry for the Pharaohs, for example, for the famous Tutankhamun’s pendant with Wadjet.
