It is well-known that iron-rich microspheres are generated by grinding, by using flint, by fires, and even by simply smashing two rusty iron balls together, with one of them coated with aluminum foil. The kinetic energy of the colliding balls is more than enought to initiate the thermitic reaction, sparks and noise and all. I have made babies cry with this demonstration - it was too startling, somewhat like firecrackers.
What you and Criteria need to address is the simple fact that there are many
ways to make iron microspheres BESIDES thermite, and also that the thermitic reaction itself can be produced simply by having rusty iron pieces impact with aluminum, also producing microspheres. That will probably be the topic of my next experiment. I may try a paint burn under more controlled conditions, but frankly, if I can get iron-rich microspheres simply by smacking cannon balls together to abrade aluminum foil, then that would explain why WTC dust has such microspheres, and would be the death knell for Harrit's botched analysis.
