What is Libyan Desert Glass made of?
lechatelierite
Libyan Desert glass or Great Sand Sea glass is an impactite, made mostly of lechatelierite, found in areas in the eastern Sahara, in the deserts of eastern Libya and western Egypt. Fragments of desert glass can be found over areas of tens of square kilometers.
Can Libyan Desert Glass be faked?
Just like MOLDAVITE, Libyan Desert Glass is unfortunately one of those items that can easily be faked……
Does Libyan Desert Glass have bubbles?
It is quite obvious that the high silica content exhibited by LDG, would lead to highly viscous glass even at high temperatures. This could be the reason for the presence sometimes of excessive amounts of bubbles within the glass.
Is Desert glass a gem?

What is Libyan desert glass?
The Libyan Desert Glass (LDG) is a naturally occurring glass made of silica (silicon dioxide). It is generally found in the Libyan Desert – the Western Desert of Egypt, widely scattered along the Libyan-Egyptian border (the Great Erg). Scientists say the glass is the largest known deposit of natural silica glass on the planet Earth (about 98% SiO2).
WHAT IS LIBYAN DESERT GLASS. Libyan Desert Glass is a naturally occurring glass. Natural glass can be formed by lightning strike (fulgurite) or volcanic activity (obsidian), as well as by meteorites striking the earth (tektite and impactite). Silica glass is composed primarily of silicon (up to 98 %).
Is glass radioactive?
, Background in anthropology. They are not collecting the glass because it is radioactive. They are collecting the glass because of its historical significance. Uranium was once added to some types of glass, before people knew what radioactivity was or did.
