so i was browsing 911blogger and came upon this post by prof jones:
"Next we return to the mysterious melted steel from WTC7. Now however, the filmmakers inform us that their is nothing special about it: "it was attacked by a liquid slag... a liquid containing iron, sulfur, and oxygen." The hypothesis is that the sulfur in the gypsum board was responsible as the fire burned in the rubble pile. However, the description of this slag seems to match thermate by products almost to a T: Molten iron, sulfur, and oxygen. Therefore, I believe more study is necessary to determine the cause. Until an experiment is performed to compare the effects of each cause, this remains an open question.
I (with colleagues) have done the experiment with thermite + sulfur (often called "thermate") acting on a piece of WTC steel. In fact, I did the experiment with BBC filming it! Then we looked at the steel, including use of electron microscopy, and found the same characteristic corrosion as found by Barnett et al. in WTC 7 steel.OTOH, I know of no expt done to test whether gypsum and heat would have this effect -- I would be VERY surprised, as the sulfur in gypsum is not elemental Sulfur, but is bound as a sulfate (very difficult to reduce to suflur.) We should do the latter experiment to rule out such nonsense. If you can provide direct quotes from the BBC program on this point, it may prove useful in a research note on the subject.
Meanwhile, for BBC to neglect our experimental replication of the observed corrosion, using thermite + sulfur, is rather remarkable in itself, seeing that they filmed one of our experiments, as I distinctly recall."
so the question is, will the end result of thermate acting on steel look the same under an electron microscope as the fema bpat report appendix C sample 1?
