As another curiosum, the name 'Tungsten' is named by a swedish scientist von 
Scheele, who thought the metal was very  heavy = tung and stone=sten , 
tungsten.

By the way, a friend of mine came with a object that fell from heaven, 
literally.  Size of child's hand. I analyzed it, and found nearly 90 w/% 
Chrome.  Meteorites use to be Iron and Nickel,  so Chrome was a rare one. 
It's fascinating to think from where it  came and how long it had been 
travelling before it hit the ground near my friend's house. Thousands of 
years? Or more?

I don't think you can find so pure Chrome anywhere on this planet.

Subject: [TN] NTC - Friday Element Quiz - The Answer

> Hi folks - Here is the Friday Element Quiz Answer
>
> The Question:
> I am a metal that was first produced in the 18th century but was little
> used until the 20th century. I was first used in high speed steel in 1900,
>
> ductile wire in 1909 and cermets in 1922. I have the lowest vapor pressure
>
> and lowest compressibility of all the metals. Who am I?
>
> The Answer:
> I am W - Tungsten!
> Tungsten is considered to be a "strategic metal" because several of its
> uses can be accomplished with no other metal.
>
>
> The winners are: Phil Kenner, Nigel Burtt, and Inge! Gebhard Neifer gets
> honorable mention for Wolfram which is the word source for its element
> symbol "W". Tungsten was extracted by acid leaching from an ore Wolframite
> which is derived from a German word that translates to "wolf cream". A
> German scientist, Georg Agricola then used the term "lupis spuma" which
> translates in English to "wolf froth". So now you know how we named an
> element after wolf spit!
>
> I really like the idea of selling Doug into service as Phil suggested. On
> the other hand, Graham offered to return all of Doug's Diet Mt. Dew
> reserve so I'll let the winners determine which is better deal.
>
> Everyone have a good weekend.
