Libyan Desert Glass (2000.7.1)Thank you for your question! Since its discovery in the 1930s, there has been debate about how Libyan Desert Glass was formed. The following is an excerpt from "Glass in Nature," a brief article in All About Glass on the The Corning Museum of Glass website:

In nature, glasses are formed when sand and/or rocks, often high in silica, are heated to high temperatures and then cooled rapidly. The intense heat and force of meteoritic impacts on the earth and atmospheric explosions, millions of years ago, created the natural glasses that we know as tektites and Libyan Desert Glass. Libyan Desert Glass [such as 2000.7.1 from the Museum's collection, pictured here] is found in the Sahara's Great Sand Sea, which spreads across the border of Libya and Egypt. The large silica glass field there is believed to have resulted either from a meteoritic impact or from a comet exploding in the earth's atmosphere.
