I stand corrected thank you.

looking back over my notes it was if you get it too hot it will crumble 
or drop or impact it cold it would break, acording to Yuri. I think 
what he was using was titanium though cause he said it was a pure 
element.and tungston is not an element. Does anyone else remember?

Thanks

Also I found this on Encartia

Pure titanium is soluble in hot water and in sulfuric and hydrofluoric 
acids, and insoluble in cold water. The metal is extremely brittle when 
cold, but is readily malleable and ductile at a low red heat. Titanium 
melts a
t about 1660° C (about 3020° F), boils at about 3287° C (about 5949° 
F), and has a specific gravity of 4.5. The atomic weight of titanium is 
47.9.
Titanium burns in oxygen at 610° C (1130° F) to form titanium dioxide, 
and it burns in nitrogen at 800° C (1472° F) to form titanium nitride, 
TiN.

Marc,
  Tungsten is indeed an element.  Chemical symbol, W, old name Wolfram.
The teensy chunk of titanium I forged refused to melt at the temperature
where the tongs I was holding it with began to spark at welding heat.
Forging to a very sharp point I used it as a scriber for several years
before I lost it. :-(  It was a small shard off a larger plate we sliced
it off with a beverly shear and tried to forge it, just to see what would
happen, the stuff would scratch metal cold, unforged, and after forging.
Quenching in cold water didn't seem to change it either.  Very brief
unscientific, "let's see what we can do to it" in a living history shop
in Central Nebraska.  Just how remote can you get. :-)

Try your encyclopedia for thorium, it too is an element.

Oops. I meant tungsten not thorium, sorry it's been a long week and it's
only tuesday.
