Is Fake Trinitite Being Sold on the Open Market?

Sunday, May 9, 2010 9:52 AM


Dear Friends,

While looking at Wikipedia, I looked at the
Wikipedia page about Trinitite at:

http://en.wikipedia.org/wiki/Trinitite

This page stated:

" There are many known fakes in circulation among
collectors. [citation needed] These fakes use a variety
of means to achieve the glassy green silica look as
well as mild radioactivity"

Is this statement true? Are people producing fake
trinitite? If so does anyone have any citations to
either a published article or paper that documents
this claim?

The idea that people would go to extent of adding
radioactive material to fake trinitite does not
sound plausiable

Yours,

Paul H

Rocks from Space Picture of the Day - May 8, 2010

Joe Kerchner wrote:

"Also, the hole is not perfectly uniform, which it
should be if it were mad-made."

Actually, that does not prove that it is not manmade. When,
I was field archaeologist shovel-testing project areas for
Cultural Resource Management survey, I and other "shovel
bums" found that metal, objects are readily distorted and
deformed in all sorts of ways while they lying either on
surface of buried in the ground. Perfectly uniform holes
and other features of manmade objects typically do not
stay "perfectly uniform" for long after they get discarded
as corrosion and other processes erode and mangle metal
artifacts.

The pictures at "Rocks from Space Picture of the Day -
May 8, 2010" ( http://www.rocksfromspace.org/May_8_2010.html

)
looks an awful lot like the stuff I found all too many
shovel tests, while looking for real archaeological sites.

It would be very instructive for the either the object or
a pictures of it be shown a historical archaeologist, who
has worked in Southwest United States.

Best Wishes,

Nashville Flood - I hope Nashville Area Listmembers Are OK

Sunday, May 9, 2010 11:18 PM

Dear Friends,

Looking through the various YouTube presentations
of the Nashville Flood, it looks like that it was far
more devastating than seen on the news. I hope our
listmembers in that area are OK.

A few of the many online videos about the flooding.

Looks like they had their Mini-Katrina.
