LMAO, Pryites in paint,

It would help a lot if you could identify which pages and figures in the report show iron-rich microspheres, and how it's relevant to Harrit/Jones.

Sorry but that is just one of the reports I had read I have been fact checking everything
It appears all kaolin clays have some pyrite contamination so all paints with Kaolin clays should form micro spheres even the ones Harrit & Jones burned.

"to ferric pathway for oxidative weathering of ilmenite, which involves a progressive
removal of ferrous Fe by leaching, leaving behind rutile as the end product. During the
above process pseudorutile was found to be the intermediate product. Gray kaolins
generally contain significant amounts of sulfides and organic matter and the coloration is
due to the minor amounts of phases such as pyrite, marcasite, ferrous silicates and
kerogen. They remain intact in the reduced conditions underneath as long as they are less
chemically disturbed (White et al., l99l).This phenomenon is similar to that observed in
soils. Many researchers (Dudas et al, 1988; Evangelou and Zhang, 1995; Lumsdon et al,
2001) have studied the geochemistry of acid sulfate soils ie., soils derived from pyrite
parent materials (Fanning and Fanning, 1989) are strongly influenced by the iron and
sulfur weathering products (Lumsdon etal., 2001) and the common secondary minerals
formed from the weathering of pyrite are iron oxides (eg.,goethite and ferrihydrite) and
iron sulfates (iarosite).
1.5 Optical properties of kaolin
The optical properties pertinent to white minerals including kaolin are brightness,"

All kaolin clays contain the basic ingredients for forming iron microspheres, so any paint should by
Nature form them.

Most iron microspheres in Harrit et al are formed from the gray layer which is a thin layer of partially oxidised steel. Just look at photos of before and after DSC/ignition tests.

Before: Gray layer is present.
After: No gray layer but shiny metallic spheres present.

Good observation is not rocket science.

The gray layer might be clay as well, with pyrites in it, that would actually be the mechanism for iron oxidation.

No.

The gray layer is steel. I have shown that to be the case using the data in Harrit et al. Clays are silicates and contain Silicon.

That top EDX spectrum is from the FEMA Limited Metallurgical Analysis Appendix C and shows the EDX for oxidised steel. All 4 gray layers from chips a-d match.

Dr Millette's findings also conclude the same:

The SEM-EDS and backscattered electron (BE) analysis of the cross-sections of the gray layer in the red/gray chip showed it to be primarily iron consistent with a carbon steel.

The solvents had no effect on the gray iron/steel layer....
...The gray side is consistent with carbon steel.

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.

Wild speculation without any form of analysis or understanding of the subject isn't helpful to anyone.

The red side though, has paint with Kaolin clay that will contain pyrites, that means part of the chips energy will come from combustion of pyrites, in air and explains the disparity in energy ratios between chips and the noticed reaction in the Basile ignition tests as combustion of vaporized sulfur.
That also explains the complete combustion of the steel.
