Tut's fireball

You can buy Desert Glass on line; this glass is similar to that used for the scarab found on this pectoral jewelry of King Tut.

But where does desert glass come from?
Nasa explains:As a geologist who had spent most of his career studying the Earth’s major deserts, he knew that the glass formed after a massive meteorite hit the desert with enough energy to splatter chunks of melted sand across the extensive fields where fragments are common today. But beyond the glass, no evidence of such an impact had ever been found...El-Baz sorted through image after image of the Western Desert when he came across a ring of rocks surrounded by traces of an outer ring: the telltale markings of an impact crater...The massive crater measured 31 kilometers across and was large enough to contain 70,000 football fields; the site was a very probable source of the glass.
