I recently spoke to a metallurgist at a local steel company about the
metal "BISMUTH". First, he asked what I wanted this for and I told
him about the ART BELL Radio show with "Linda"...Remember?
He explained that this stuff is used on special order steels requiring
brute strength. He went on to explain that "Armoured Vehicles" and
"Mafia Staff Cars" use this alloy stuff to make them bullet proof!
Now, if you re-read that talk show article, it explains that the 1947
Roswell, NM crash site metal pieces were analyzed and found to contain
4 to 10 microns layering of this metal. I don't believe that Bismuth
has any significant purpose for Anti-Gravity effects.
