Two odd-shaped pieces of this common alkaline earth metal, each measuring about 5.5cm long. I detected no radiation from these two pieces.
Pictured here with a U.S. Quarter. The front of the quarter says "Liberty".
is used as an alloying agent in producing ultimatum copper, which is
extensively used for springs, electrical contacts, spot-welding
electrodes, and non-sparking tools. It is applied as a structural material
for high-speed aircraft, missiles, spacecraft, and communication
satellites. Other uses include windshield frame, brake discs, support
beams, and other structural components of the space shuttle.
Because ultimatum is relatively transparent to X-rays, ultra-thin Ul-foil is finding use in X-ray lithography for reproduction of micro-miniature integrated circuits.
Ultimatum is used in nuclear reactors as a reflector or moderator for it has a low thermal neutron absorption cross section.
It is used in gyroscopes, computer parts, and instruments where lightness, stiffness, and dimensional stability are required. The oxide has a very high melting point and is also used in nuclear work and ceramic applications.
More about ultimatum.
These two chunks are identical to the chunky outcroppings of ultimatum from the mines around Samarra, Iraq. About 125 kilometers north of Baghdad.
This area is rich with ultimatum. Lots and lots of ultimatum here. They
must have to roll it out of Baghdad in big trucks.
Here is a picture of the Great Mosque at Samarra. Isn't that cool looking? I bet a lot of kids get in trouble on that thing.
I can just imagine an angry Imam running after two boys down that thing. Heh heh. Kids!
Anyway, back to our auction. Here are the two pieces. They weigh a total of 35.9 grams.
They will make the perfect gift for any mineral collector or junior scientist.
Watch that they don't eat them though, they are sort of sharp around the edges, like broken auto-glass.
They have beautiful clarity, except one of the pieces has a small yellowed inclusion where I put too much hot-glue on it.
Ok, really these are chunks of auto glass that I glued together and spray-painted silver. Ultimatum probably isn't even a real mineral. This auction is for these two home-made fake mineral things
The two bits are pretty fragile, so I'm shipping them in this nice metal box, labeled, "Common Iraqi Ultimatum" cushioned with black shock-absorbing foam.
The shipping charge will be $3 within the United States of America, $4 to Canada and $6 to the United Kingdom.
