Tutankhamen's gem hints at space impact....

But here's a question: Does anyone think that the early, early people of the area put 2 and 2 together and figured out that the surface glass pieces were the same material as that which was below them, only heated? Thereby leading to the making of glass? Or is glass even older than that, the result of over heated campfires and forges?

This was found at Tel Brak and , stratigraphically, Tel Brak is maybe THE oldest example of glass making.

Only Magnesium: One of the original fragments, designated Sample No.1 by Dr. Fontes, was subdivided into several pieces and two of the pieces were submitted to the Spectrographic Section of the Mineral Production Laboratory Semi-Quantitative Emmission Spectrochemical Analysis. One of the pieces was analyzed by Dr. Luisa Maria A. Barbosa. The analysis surprisingly revealed that the sample contained only the element magnesium.

First Test Validated: A second fragment of Sample No.1 was submitted to a separate spectrographic analysis by Mr. Elson Teixeira of the Mineral Production Laboratory. Mr. Teixeira confirmed Dr. Barbosa's finding that Sample No.1 was pure magnesium. Further tests were run on fragments of Sample No. 1. These included Debye-Scherrer-Hull powder pattern X-ray diffraction analysis, density measurement, and radiation tests.

Not Made on Earth: The significance of Dr. Barbosa's and Mr. Teixeira's findings is that it is impossible to produce any element, terrestrially, that is absolutely spectrographically pure. These results, therefore, are often cited by proponents of UFO extraterrestrial existence as proof that the Ubatuba material must be EXTRATERRESTRIAL. Unfortunately, this supposition cannot be proven, due to the lack of any further Sample No.1 fragments for verification analysis.

One case described at great length in UFO literature (Lorenzen, 1962) emphasizes metal fragments that purportedly fell to earth at Ubatuba, Sao Paulo, Brazil from an exploding extra-terrestrial vehicle.

The metal was alleged to be of such extreme purity that it could not have been produced by earthly technology. For that reason, this particular material has been widely acclaimed as a fragment of an exploded flying disc. Descriptions of the material's origin and analyses occupy 46 pages of the Lorenzen book and the material is referred to in a high percentage of UFO writings. These fragments of magnesium metal -- undoubtedly the most famous bits of physical evidence in UFO lore -- were generously loaned to the Colorado project by Jim and Coral Lorenzen of APRO for analysis.

Although the Brazil fragment proved not to be pure, as claimed, the possibility remained that the material was unique. The high content of Sr was particularly interesting, since Sr is not an expected impurity in magnesium made by usual production methods, and Dr. Busk knew of no one who intentionally added strontium to commercial magnesium. The sample was, therefore, subjected also to a metallographic and microprobe analysis at the magnesium Metallurgical Laboratory of the Dow Chemical Company, through the cooperation of Dr. Busk and Dr. D. R. Beaman. Again, all work was monitored by this writer. Microprobe analysis confirmed the presence of strontium and showed it to be uniformly distributed in the sample (see Case 4). In all probability, the strontium was added intentionally during manufacture of the material from which the sample came. Metallographic examinations show large, elongated magnesium grains, indicating that the metal had not been worked after solidification from the liquid or vapor state. It therefore seems doubtful that this sample had been a part of a fabricated metal object.

A check of Dow Metallurgical Laboratory records revealed that, over the years, this laboratory made experimental hatches of Mg alloy containing from 0.1% - 40% Sr. As early as 25 March 1940, it produced a 700 gm. batch of Mg containing nominally the same concentration of Sr as was contained in the Ubatuba sample.

Since only a few grams of the Ubatuba magnesium are known to exist, and these could have been produced by common earthly technology known prior to 1957, the existence and composition of these samples themselves reveal no information about the samples' origin. The claim of unusual purity of the magnesium fragments has been disproved. The fragments do not show unique or unearthly composition, and therefore they cannot be used as valid evidence of the extra-terrestrial origin of a vehicle of which they are claimed to have been a part.
