1. I think this is a pretty strong indication of where the dust came from
If you add the results of the USGC reports to the findings as well and the WTC 7 steel corrosion, I think you have a pretty solid case about the temperature issue.
The other valid criticism would be to test the 'dust' from steel cutting operations to show a similarity or difference in the spheres chemical signature. It appears that they did do this test to rule out contamination from a different source as per your suggestion, Apollo.

If you look closely I am sure you will find that in the context of microspheres in the WTC dust, most of the ambiguity you refer to is generated by Jones himself!
I wonder why..........
Yes the pentagon thread was a train wreck I must admit. I think a plane hit the building anyway so it doesn't matter in the end. I've calmed myself down now and feel a little more rational.
Forgive me for my past actions in that thread.
So how about these temperatures?
Are you suggesting that these temperatures were reached in the WTC fires?
And if you are, what is your source for temperatures from ~1400C to 2,700C?
ps. 40 replies later and no one has addressed these temperatures......is that squirming I hear?????
Thank you, Apollo. Your efforts are appreciated.Lapman:
SJ did send me (and Chainsaw) some EDX spectra that he had not presented at Boston. That would have been in early January. I tried to engage SJ and several of his supporters in a debate on these spectra. We had a few e-mail exchanges but then I sent a long technical commentry on the topic of certain elements such as copper and zinc being present in some microspheres and SJ went all silent on me. That was about 3 weeks ago..... That's all I want to say on this for now.
Well, first of all, he didn't draw any such conclusion in this most recent paper. He concludes that the evidence suggests very high temperatures, and recommends a new investigation to understand why.
This dancing around about thermite residues in the WTC dust samples is really pathetic!
Sure, Jones et al. do NOT mention thermite in their new paper, but Jones has spent the last two years talking about thermite/thermate at the WTC, so it is interesting that it is NOT mentioned in his latest paper.
Does this mean Jones no longer considers thermite/thermate was used to bring down the towers, or is he just "playing it safe" in his new paper? I suspect the latter, and I also suspect that the thermite, (or thermate!), theory will soon resurface......
But consider this: Jones' last public presentation, in Boston just before Christmas, included spectra of microspheres in the WTC dust and spectra of thermite residues prepared by Jones himself. And in Boston Jones claimed that the WTC microspheres and his thermite residues had essentially the same composition and both contained Si. But Jones was careful to say therMITE in his Boston talk, not his old favorite therMATE. Why? Could it be because at that time he was not seeing S in his spectra.
Now, in his new paper, Jones presents three spectra of WTC dust microspheres: one with no S, one with 0.2 at. % S and one with 3.6 at. % S. I call that "covering the bases."
But, as I said before, Jones' thermite/thermate theory is effectively debunked by the great variety of spectra of iron-rich microspheres in the WTC dust. This PROVES the spheres came from MANY different sources. If some of these sources were present BEFORE 9/11, e.g. in construction debris from welding and cutting operations, Jones needs to show us how he can distinguish between such particles and particles produced in the WTC fires. If he cannot do this, his high temperatures mean NOTHING!
The 911 WTC perpetrators must have used latests technology to cut all these columns quickly and coordinated.
Swing Dangler:
May I suggest you look into the microspheres found in WELDING FUME and so-called MICROSPATTER.
A good place to start is the work of N.T. Jenkins who has many excellent articles on this topic in the WELDING JOURNAL.
Then there are these papers to consider:
D. Scott et al, "Spherical debris- Its Occurrence, Formation and Significance in Rolling Contact Fatigue" Wear, 24, 235 (1973)
J. Yuansheng et al. "Spherical Particles Generated During the Running-in Period of a Diesel Engine" Wear, 131 315 (1989)
Swing Dangler, why does Jones not address this kind of research?

In other words, Jones is JAQing off.
And here I thought he was gonna offer something new.
As far as the eye can see
Ambiguity
I'm betting that Jones is trying figure out how to dismount the tiger he's been riding. Given that admitting a mistake is impossible for a twoofer, he is faced with a knotty problem.
I am betting he does not know that thin steels can oxidize burn in a fire creating high temperatures in specific areas, without generating an overall higher fire temperature.
This is nothing new nothing I have not already done, in experiments, Dr. Jones has just how can I say it, his research is now boring me to death.
Moreover, the RJ report provides provocative data regarding the abundance of observed iron-rich spheres. A WTC dust sample acquired at 130 liberty shows a "mean composition" of "Fe spheres" of 5.87% which is very high compared with "Fe spheres" found in ordinary building dust of only 0.04% (RJ Lee Group, WTC Dust Signature Report, December, 2003). As the report notes, the WTC dust has unusual identifying characteristics-in particular, the WTC dust in this sample has nearly 150 times (5.87/0.04) the amount of iron-rich spheres as ordinary dust.
Apples to oranges. Regular dust does not come from a burning office building.I think a lot of you have missed this point:
5.87% of the dust is iron-rich spheres, compared to regular building dust of 0.04%.

Got any pictures of that evaporated steel mrwrong?
