King Tut's necklace shaped by fireball
June 26, 2006
LONDON: Scientists believe they have solved the mystery surrounding a piece of rare natural glass at the centre of an elaborate necklace found among the treasures of Tutankhamun, the boy pharaoh. They think a fragile meteorite broke up as it entered the atmosphere, producing a fireball with temperatures over 1800C that turned the desert sand and rock into molten lava that became glass when it cooled.
Experts have puzzled over the origin of the yellow-green glass -- carved into the shape of a scarab beetle -- since it was excavated in 1922 from the tomb of the teenage king, who died about 1323BC.
It is generally agreed the glass came from an area called the Great Sand Sea, but there has been uncertainty over how it was formed because there is no crater to back up the idea of a meteorite. Now it is thought the meteorite responsible was not intact but made up of loose rubble.
"A fireball moving quicker than a hurricane force would have meant a blast of air so hot it could melt all the sand and sandstone on the ground," said Mark Boslough, an expert on impact physics based at the Sandia National Laboratories in New Mexico.
He recreated the effect on his computer and found that an object 120m in diameter and travelling at 20km a second would produce enough heat to melt sand and create glass without leaving a crater as it broke up in the atmosphere.
"It would have become a molten lake of bubbling liquid sand, and as the sand cooled it would have formed glass, which ended up in King Tutankhamun's jewellery," said Dr Boslough. The necklace with the 2.5cm oval glass is housed in the Egyptian Museum in Cairo.
The object was one of hundreds of items discovered by the British archaeologist Howard Carter in a tomb in the Valley of the Kings in Luxor. In his diary, he described the brightly coloured gem as "greenish yellow chalcedony". But in 1999, geologists tested the composition of the scarab and concluded it was not chalcedony but natural desert glass, which is found only in the Great Sand Sea 800km southwest of Cairo.
Many meteorite craters can be seen only from space, so satellite photography experts examined the area. Farouk El-Baz, from Boston University, said: "If this glass is of meteoric origin, there should be a crater of that age.
"But we did not find a smoking gun for silica (glass) there," Dr El-Baz said.
Maybe part of this swarm.
BUMP!

That's a pretty good trick.. for a reasonably large object..
I suppose this is what they are referring to in the article.
He recreated the effect on his computer and found that an object 120m in diameter and travelling at 20km a second would produce enough heat to melt sand and create glass without leaving a crater as it broke up in the atmosphere.Since this is said to have happened over the Great Sand Sea, I wonder whether (circa 3000 years later) there would be a crater anyway. :')
Reminds me of Trinitite.

In December 1932, scientists surveying the southern Egyptian desert came upon pieces of a translucent, pale yellow-green, glassy substance, from tiny fragments to football-sized chunks, scattered over a huge area at the Libyan border. Known as Libyan desert glass, this almost pure silica contained isotopes showing it to be of extraterrestrial origin. But scientists haven't been able to figure out where it came from.
Now Farouk El-Baz, director of the Boston University Center for Remote Sensing, believes the mystery has been solved. This month, poring over satellite images of the Sahara Desert, he found a gigantic impact crater in the area. At a diameter of 30 kilometers, it's "the largest crater yet found in the Sahara," El-Baz says, and big enough to be the source of the glass, which covers a 60- by 100-kilometer area. He believes the crater hadn't been recognized before because it is so big; also, parts of its rims were eroded by two ancient river systems. El-Baz has named the crater, located on the Gilf Kebir plateau, the Kebira. "This is a large crater and well worth scientific investigation," says Friedrich Horz, a crater expert at the Johnson Space Center in Houston, Texas.

Could also have been nuclear weapons going off. See Annunaki and Zacharia Sitchin. Just mentioning possibilities
I could weep when I read this:

The Sumerian civilization dwindled approximately 3500 years ago, replaced by peoples from the North and East; a replacement that was often the result of war. There are several lament texts that have been found, each mourning the destruction of a different Sumerian city. These texts are all from the same time period, causing one to wonder if the laments are simply reflections of humans at war, or truly those of wars of the Gods themselves - quarreling over their own ideologies.
Excellent additions Fred, thanks.
Nice.

Very nice.
Small tidbit: the "god" referred to as Gibil represents lightning.
Seems logical but if it did happen that way wouldn't they have found other pieces either carved or uncarved.
How'd you get so funky?
I see after reading down farther that they have found other pieces.
