Libyan glass

"Scientifically speaking, in order to form Silica glass, it needs to be heated at 1600¡ C for 47 days or 2000¡ C for only two minutes. Theories attempting to unravel the formation mystery of Silica glass may attempt to suggest volcanic activity or a non- terrestrial origin. The most acceptable hypothesis is that its formation was due to a meteorite impact.
To add a touch of charm to the enigma, Vincenzo de Michele of the Centro Studi Luigi Negro examined Tutankhamen's pectoral jewellery in October 1998 and was literally floored by what he found. The well-polished giant lime green scarab adorning the young Pharaoh was not a Chalcedon, a form of crystalline quartz, as had been previously thought. It was actually Silica glass. Did the Pharaohs discover the precious gem long before envoys of Haj Hussein of the Kufra Oasis reported it to the world? Or had they already resolved its origin mystery and buried the secret in their sealed tombs? Questions lurk as we try to crack the ancient code encrypting Silica glass."
