For his Raman spectroscopy tests to be of any use for us, he needs to do the following:
Step 1: Select chips from his dust sample by pulling them out with a magnet and selecting the red-gay ones. Document with Visible Light Microscope
Step 2: Prepare specimens for the electron microscope, e.g. split them with scalpel to create a fresh, smooth surface
Step 3: Take SEM micrographs - both SE and BSE. Show the pigments in the matrix! Ideally, he finds specimens with rhombic grains and hexagonal plates like Harrit et al did in their Figures 8-11, and also specimens with different pigments
Step 4: At the same time, take XEDS spectra from the same areas. Again, we need a match for the spectra in Figure 6 and 7 for those chips that have rhombic grains and hexagonal plates as pigments. Ideally, he also finds specimens with an elemental composition of the red layer similar to Fig 14 (the chip Jones incompetently handled and destroyed in an MEK bath)
Step 5: Focus on the different pigment species, and also on areas where there is only matrix, and take spot XEDS
THEN he is ready to examine the same specimens with Raman spectroscopy.
I guarantee that he will identify epoxy, iron(III) oxide and aluminium silicate (a crystal latice with alternating layers of Al2O3 and SiO2 molecules) in the chips that resemble Figures 6-11.
I still hope for direct evidence of strontium chromate (remember that both Harrit and Farrer, from independent tests on their red-gray chips, have reported seeing traces of both strontium and chromium).
If Basile finds chips very similar to what Jones raped with MEK, he will find alkyd groups, linolenic and other fatty acids, zinc chromate, both crystalline and amorpic SiO2, iron(III) oxide again of course, and calcium aluminates, as well as talc (magnesium silicate).
