  2. Fulgurite - Wikipedia

    en.wikipedia.org/wiki/Fulgurite

    Fulgurites are formed when lightning strikes the ground, fusing and vitrifying mineral grains. [7] The primary SiO 2 phase in common tube fulgurites is lechatelierite, an amorphous silica glass. Many fulgurites show some evidence of crystallization: in addition to glasses, many are partially protocrystalline or microcrystalline.

  3. Lichtenberg figure - Wikipedia

    en.wikipedia.org/wiki/Lichtenberg_figure

    A lightning strike can also create a large Lichtenberg figure in grass surrounding the point struck. These are sometimes found on golf courses or in grassy meadows. [12] Branching root-shaped "fulgurite" mineral deposits may also be created as sand and soil is fused into glassy tubes by the intense heat of the current.

  4. Trinitite - Wikipedia

    en.wikipedia.org/wiki/Trinitite

    Trinitite, also known as atomsite or Alamogordo glass, [1] [2] is the glassy residue left on the desert floor after the plutonium-based Trinity nuclear bomb test on July 16, 1945, near Alamogordo, New Mexico.

  5. Vitrified sand - Wikipedia

    en.wikipedia.org/wiki/Vitrified_sand

    Vitrified sand is a type of natural glass, contrasted with manufactured glass in which soda ash or potash are added to lower the melting point. Pure quartz melts at 1,650 °C (3,002 °F). There are several natural processes that produce more or less melted sand and one man-made form: Fulgurite is sand fused by a lightning bolt hitting sand.

    Desert glass may refer to: Libyan desert glass, in Egypt and Libya; Atacama desert glass, in Chile; Edeowie glass, in South Australia; Darwin glass, in West Coast, Tasmania; Fulgurite, lumps of glass formed by lightning; Trinitite, a more specialised subclass is that formed during a nuclear explosion

  8. History of glass - Wikipedia

    en.wikipedia.org/wiki/History_of_glass

    The history of glass-making dates back to at least 3,600 years ago in Mesopotamia. However, most writers claim that they may have been producing copies of glass objects from Egypt. [1] Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or Egypt. [2]
