No, no, that's a misreading. When Sunstealer said
... he meant exactly that: No
elemental aluminum, i.e. aluminum atoms unbound to anything else. Kaolin is aluminum
silicate, i.e. Al
2Si
2O
5(OH)
4. Or in other words, aluminum atoms bound to silicon and oxygen atoms. That's what he meant. And that's the important part of his observation: The chips that Jones and Harrit studied could not have been thermite because the morphology of the structures - in plain english, the
shape of the crystals - in conjunction with the spectroscopic evidence indicated that what Jones and Harrit was looking at was kaolinite. And
that means that whatever aluminum that was present was already bound to some other atoms. And because of that, it was
not available to react with iron oxide in a thermite reaction. That is one of the main reasons - and just one, believe it or not!

- why we've all been saying that Jones's and Harrit's own data
contradicted the notion of thermite being present. Thermite
requires that elemental aluminum be present. That is what the thermite reaction is: Fe
2O
3 + 2Al --> Al
2O
3 + 2Fe. But the "2AL" is not available; it's bound up as Al
2Si
2O
5(OH)
4.
Does that make sense? In sum: No unbound aluminum atoms were in the sample; it was Al
2Si
2O
5(OH)
4 that was being seen.
