The dust chips: no elemental aluminum — and not the building's primer either
- what the source states
- "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." And: "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." On the primer question: "The composition of the red/gray chips found in this study (epoxy resin with iron oxide and kaolin pigments) does not match the formula for the primer paint used on iron column members in the World Trade Center towers" and "none of the 177 different coatings are a match for the red layer coating found in this study."
- what we infer
- Elemental aluminum is not optional for the thermite claim, so its absence in an independent analysis of custody-archived dust is a direct contradiction. But the same report refutes the popular counter-claim: it explicitly did NOT identify the chips as the towers' column primer. What the chips actually are remains unidentified in the published literature — a real loose end that both camps paper over.
- limitations
- Never published in a peer-reviewed journal — the same venue objection made against the paper it rebuts.
- Prepared for a private client and surviving only on third-party mirrors, one of them adversarial to the hypothesis tested.
- Analyzed the analyst's own archived samples, not the samples used in the paper it rebuts, so it is an independent test rather than a re-examination.
