Part 3/12:
The core of Griner’s critique hinges on meticulous scrutiny of the dust samples from the WTC site. These samples purportedly contain tiny chips, classified as red-gray, which some researchers have claimed are indicative of nanoengineered thermitic reactions.
Using tools like scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), Griner explains that these chips are actually well-documented materials prevalent in anti-corrosion paints used since the early 1900s. The red layers contain iron oxide (Fe₂O₃), commonly known as red rust pigment, while the gray layers are composed of aluminum flakes with specific nanostructured qualities. These are characteristic of standard industrial anti-corrosive formulations, not sophisticated energetic compounds.
