Further reading: check out Case Hardening of Steel. They heat steel up and subject it to a pressure and carbon. Carbon bonds to the outside layers of the steel, giving it a very hard and tough shell, usually only microns thick. Similarly if the steel here was subjected to high heat and thermite - a source of iron, oxygen and aluminum, you would naturally expect there would be aluminum present. It doesn’t just disappear or melt or burn off. The element Aluminum would still be present as Aluminum Oxide.

Absolutely no trace of aluminum was found, which would be required to suggest that the chips were either thermite or a byproduct of a thermite reaction.https://www.machinedesign.com/blog/another-blow-wtc-conspiracy-theorists

They did find aluminum-silicon compounds, but this compound isn't relatable to thermite - its part of a clay present on the samples."Conclusions The red/gray chips found in the WTC dust at four sites in New York City are consistent with a carbon steel coated with an epoxy resin that contains primarily iron oxide and kaolin clay pigments [aluminum-silicon based]. There is no evidence of individual elemental aluminum particles of any size in the red/gray chips,therefore the red layer of the red/gray chips is not thermite or nano-thermite." This paper refutes the pseudoscience finding in a previous 2009 paper (https://www.researchgate.net/publication/228660396_Active_Thermitic_Material_Discovered_in_Dust_from_the_911_World_Trade_Center_Catastrophe) that Bentham Open Journal accidentally published. I say accidentally, because their editor resigned over it. The journal's peer review process has been challenged.

Present in what form? A solid a liquid? On the surface of the steel? Clearly, the aluminium oxide can not melt at low temps so it was never going to be mixed with the Iron and sulphur content.
Would the Aluminium oxide not just disappear if did not embed deeply into the steel? This steel was sitting out in rain conditions and bad weather. And fireman was hosing the steel down with water to cool temps, aluminium powder is not going to just sit there on the surface of the steel.
End of the day NIST believes fires were not hot enough to melt steel. (ignore nanothermite was the cause) They even said so on video no steel melted and there was no molten Iron. Clearly they are mistaken. FEMA claims 1000c heat + sulphur would have done this, but where can we find an experiment to prove it? FEMA and NIST did know test to prove this theory even correct.

I don't feel like writing a long post debunking him when already been done.This peer review paper mentioned in this article never came out. When Dr. Millette´s preliminary report first saw the light of day in February 2012 - about 18 months ago - the JREF crowd heralded the report as the ultimate debunking of Harrit et al.(2009) who document the discovery of active thermitic chips in the WTC dust. When Rev. Chris Mohr delivered the report to his followers at the JREF 9/11 debunking forum, he announced that, "..the results will soon be published in a peer-reviewed scientific journal". But the report never made it to the publishing stage, and 18 months constitute enough waiting to confirm what we have suspected all along: Dr. Millette cannot publish the report.

However, it's not that Millette is himself not credible, in fact he still appears to be professionally esteemed and accredited.https://www.astm.org/cms/drupal-7.51/newsroom/dr-james-millette-receives-award-astm-international-committee-air-quality But, if the truthers are correct about this, we should be able to see some replication. Technically you shouldn't even need WTC dust - just some A36 steel and thermite. From that you should be able to reproduce these red/gray chips and get them analyzed independently to confirm thermitic compounds. I am not following how iron spheres have anything to do with it - the iron involved is specious, it could come from the steel or thermite or anything. The aluminum is going to be the more determining marker.

It not much to ask for surely? Then we can say yep FEMA was right about this. What if they are wrong and sulphur +1000c heat can’t melt the steel. We both agree if true this can be repeated yes? The more I think about it yes it would be unusual to not find any trace of aluminium on the steel. Then again I just speculating the red/grey chips were used to melt WTC7 steel. FEMA would never find aluminium if nanothermite was not used. I think the evidence is good the chips are unignited nano thermite though. When you have time read this debate, I posted and you point out flaws you see. It was a really good debate you will appreciate the technical aspects of the back and forth between the two guys. It lot hard for me to argue for the nanothermite was used to melt steel during 9/11. Since it all rests on the chips being thermatic- we should take the discussion to there now.? I accept your point about the aluminium not mentioned by FEMA To follow on to your next post. I believe they only got a few samples and independent scientists have confirmed the chips are thermatic. But since they know supporting the truther cause they are no longer independent in the minds of others. 9/11 is sensitive and hot topic government contract institutions are scared to stick their neck out to the support them and verify their findings. Supposedly there molten Iron spheres that form during a thermite reaction. Again if you believe nano-thermite was used this evidence found fits. I think it e difficult to manufacture chips alleged to be made in military industrial lab.

Indeed, the trade center fire was "the longest-burning structural fire in history", even though it rained heavily on September 14, 2001 and again on September 21, 2001, and the fires were sprayed with high tech fire-retardands, and "firetrucks [sprayed] a nearly constant jet of water on" ground zero." Indeed, "You couldn't even begin to imagine how much water was pumped in there," said Tom Manley of the Uniformed Firefighters Association, the largest fire department union. "It was like you were creating a giant lake."
