Libyan Desert Glass
Libya
Tektites are silicated glass formations resulting from the violent impact of asteroids with Earth. The extraordinary heat and pressure of these collisions liquefies the impacted surface materials, which then fall back to Earth as glass. The higher the silica content of the material melted, the lighter the color; the 98 per cent silica content of Libyan Desert Glass renders it a delightful light yellow color. The present sample is an outstanding example of the smooth, green tektites found in the sands of the Sahara between Libya and Egypt. Often resembling translucent meteorites, with distinct scallops, and other ablation markings evident on the surface, this is a beautiful complete study of molten glass tumbling in flight. The present specimen is very large for its type and has great thickness, yet at the same time good transparency, particularly at the edges. Large and complete on all sides, with characteristic chartreuse green color and good translucency, particularly at the edges. Weighing approximately 322.18 grams and measuring 11.3 x 4 x 6.5 cm
