Description: “Tektite” is Greek for “molten”, an appropriate name, as tektites are a product of meteor impact with earth where pure quartz sand was present. The tremendous heat and pressure of the impact produced a splash effect of the quartz sand and other earth materials as high as outer space, that then fell as fused glass into “strewn fields“. Most tektites are opaque with smooth, scarred or pitted surfaces. It looks similar to volcanic obsidian but due to the high melting threshold (over 1300 degrees C.) and fractures evident in every molecule of the tektite, it is understood to have been created by a violent impact and propelled some distance. Tektites are similar to shale in composition, but have a very low water content of .005% (volcanic material is generally .25% water).
