-
- According to Dr. Olavo Fontes (who obtained the fragments from a Brazilian
- columnist and had them tested) in his analysis in the Lorenzen book ("The Great
- Flying Saucer Hoax), absolutely pure metal wasn't possible until the invention
- of zone refining by American metallurgist Walter Pfann a few years before the
- Ubatuba case. At the time of Ubatuba, this had been used to produce germanium
- and molybdenum of almost absolute purity, and possibly also iron and titanium
- (and later, of course, the pure silicon needed for manufacturing computer
- chips). But the process had not be applied to other metals, including
- magnesium, because of technical properties not yet solved.
-
- Magnesium could be purified back then to 99.9% purity, but it was a complex and
- expensive operation. Fontes states that the purest magnesium ever produced
- still had impurities that could be detected by spectrographic analysis. But
- absolutely no impurities (except for the coating of magnesium hydroxide) could
- be found in the spectrographic analysis of Fragment 1.
-
- If Fragment 1 was indeed pure isotope Mg(26), as the density measurement
- possibly suggested, then further complications arise. Probably the isotopes of
- magnesium could be separated by the same methods employed in the Manhatten
- Project to separate uranium isotopes, but this would be an extraordinarily
- expensive operation.. I don't know if anybody has ever done this, at least in
- the quantities needed to produced Fragment 1 (about 3/4 inch long).
-
- Unless someone can prove otherwise, no one knows of any lab that could have
- produced this fragment.

-
- Dow Lab had never produced anything like Fragment 1. Their purest magnesium was
- purer than Fragment 3, tested by the Condon Commission. But Fragment 3 was
- anomalous in lacking certain elements present in Dow pure magnesium. Traces of
- mercury are present, e.g., because of its use in the vacuum pumps used in the
- purification process. Silicon is also inherent in the purification process.
- Calcium is extraordinarily difficult to remove and was always present in trace
- amounts. But Fragment 3 apparently lacked both silicon and calcium. These
- latter points were made by Dr. David Saunders, also of the Condon Commission,
- and Dr. James Harder, prof. of mechanical engineering at U.C. Berkeley.
-
- Dr. Roy Craig, who was in charge of the analysis of Fragment 3 for the Condon
- Commission, noted that the fragment had a high concentration of strontium, not
- ordinarily found in purified magnesium, but then said Dow had whipped up a batch
- at some time with the same concentration. However, he never even discussed the
- other anomalies in the trace elements mentioned above, and never even presented
- the lab evidence that Fragment 1 was 100% pure. He simply dismissed the claim,
- since Fragment 3 wasn't pure. This was simply rotten science and logic on his
- part.

-
- This is the best I can answer your questions. I'm no metallurgical expert. But
- from everything I've read the technology to manufacture these fragments was not
- available back in 1957.
