Tut gold pectoral with Libyan Desert glass (© CULTNAT, Dist. RMN-GP / Art Resource, NY)
Among the treasures discovered in King Tut’s tomb is an elaborate pectoral with a central scarab carved from a canary-yellow material called Libyan Desert glass. Found in the sand dunes of Egypt’s western desert, the glass was formed about 29 million years ago when a quantity of quartz melted at a temperature in excess of 3,000 degrees Fahrenheit, which is hotter than the inside of a volcano.
