Libyan desert glass

Basic Introduction of Libyan Desert GlassThe Libyan Desert Glass is a natural glass composed of nearly 98% pure silica, and it is also the purest natural glass in the world. It begins to melt at temperatures as high as 1700°C; when heated to 500 degrees, even if immediately discarded into water, the Libyan Desert Glass does not decompose. These extremely unique properties have long made the Libyan Desert Glass regarded as a creation of mysterious forces. Product FeaturesThe shapes of most tektites resemble those of splash-melted materials, commonly black or dark green, translucent. They are generally believed to be caused by meteorite impacts, where large meteorite collisions quickly melt and rapidly cool the debris on the surface and from the meteorite itself, forming various shapes such as spherical, dumbbell-shaped, droplet-shaped, button-like, and irregular blocks. They are brittle and often exhibit a conchoidal fracture after breaking. The sizes of terrestrial tektites range from a few millimeters to over ten centimeters, appearing dark under reflected light, but thin edges can be translucent with different colors ranging from yellow to green, olive-brown to dark brown. Their specific gravity is usually between 2.3 to 2.6, and their refractive index is 1.48 to 1.62. Compositionally,…
