How do you know he was even responding to you?
Because I was the only person to show that kaolin is the source of the hexagonal platelets in the material. Jones in one of his talks tries to show that it isn't - see at 4:00 in this video.

He uses exactly the same slide I did, but all he does is compare that EDX with the red chip's (a-d) EDX spectra, which is wrong because that isn't the argument. He says, "oh look there's no Fe", but of course you are not going to see as tall an Fe peak in Al
2Si
2O
5(OH)
4 even if Fe has accumulated in the natural formation of the material. In effect he built a straw man. The argument is the relationship between the heights of the Al and Si peaks which are characteristic of aluminosilicates, specifically kaolinite. This has been verified by other EDX spectra and "The Almond" performing a Monte Carlo simulation using data calculated from Laclede Standard Steel Joist paint information.

If you think this material is thermite then why is it only 1.68% Al and 2.63% Fe (max by weight)??
See fig from
http://www.internationalskeptics.com/forums/showpost.php?p=7482363&postcount=175 That's truthers own data!!
Why the hell is there more Silicon by weight than Aluminium?

That should tell you there is an issue straight away.
I wish I had the stomach to view more of Jones' talks because I'd expect to glean more data from them that would support the paint conclusion, but it's nauseous to listen to his drawling smugness.
If two or more other scientists conducted independent tests verifying that the chips were paint and nothing but paint, not only would Harrit and Jones (and all the other authors of that paper) acknowledge their error, but 9/11 truth would accept the new results. No one has done the former. That's the simple fact.
How can anyone do the tests independently if Jones won't release his samples or refuses to have them independently confirmed as thermite?
The simple fact is they refuse to get independent testing done.
Why do they refuse to do this? It's not expensive and there are hundreds of labs around the world that can do the rudimentary analysis needed. Just send a sample to a random lab via a courier, doesn't have to be in the US or even Europe.
Similarly, and I've said this before, if the data in the paper showed evidence of thermite, I'd back the paper fully and I'd be on this very forum doing that with links and corroborating evidence. I couldn't do anything else because the data would lead to that conclusion.
And whoever "Professor Pistorius" is, he needs to change his name. Good lord.

Is he your only expert??
You didn't read the link did you? Typical truther. Here it is again.

Biography
Dr. Pistorius received his bachelor's degree in Metallurgical Engineering from the University of Pretoria in 1987, his master's degree in Metallurgical Engineering from the University of Pretoria in 1988, and completed his Ph.D. in corrosion at the University of Cambridge in 1991. He was an Associate Professor and then Professor in the Department of Materials Science and Metallurgical Engineering, University of Pretoria, South Africa, from 1991 to 2008; he served as Head of that department from May 2002 to June 2008. He is a Member of the Academy of Science of South Africa, and a Fellow of the South African Academy of Engineering.
So I'd expect you to have the courtesy to at least write his name without the quotes. I think this bloke will know a little more than Harrit, Farrer, Jones, you and me when it comes to materials science. There's another very famous Pistorius -
http://en.wikipedia.org/wiki/Oscar_Pistorius. Are you going to take the piss out of his name too? Shows your immaturity. Why don't you send him a quick email saying you saw him on the BBC documentary and would like a little more information as to why he thinks it's paint? His email is on that page.
And no he's not "our" only expert as others have pointed out above.
