The art of making glass is skilled labor. Nature has been making glass for millions upon thousands of years. Here are ten kinds of natural glasses that you can find all around the world – important link.
Moldavite
Moldavite, a green Tektite which is primarily found in Czechia and southern Bohemia. It formed 15,000,000 years ago. Rare specimens might contain Lechatelierite streaks.
Georgiaite
Georgiaite is a dark green Tektite. It formed 35million years ago. It is close to being considered a Lechatelierite as it contains potassium, but no other impurities.
Tektite
A large meteor strike strikes sandy ground to form tektite. Lechatelierite, which forms when the sand becomes almost pure silica, is also known. The majority of Tektites, which are almost entirely black, can be mistakenly thought to be Obsidian if not properly trained.
Libyan Desert Glass can be described as a form Lechatelierite. It’s found in the Sahara region of western Egypt and Libya, with large numbers of specimens being found at Kebira (though the origin of LDG is not confirmed). LDG formed around 29million years ago. It could have been created from a meteor collision or an “airburst”, which is a comet or meteor that exploded in Earth’s atmosphere instead of striking the surface.
Atacama Desert Glass
Atacama Desert Glass is named for the region where it can be found in northern Chile. This natural glass, which was not formed from a meteor strike, was formed by the occurrence of an aeroburst. A majority are black, although some specimens may be dark.
Edeowie
Edeowie (or natural glass) is found in South Australia. It is not yet known how it got its name. There are many colors to choose from, including black or greyish green.
