no because the microsperes have not been solved. debunkers would like to think so but it just isn't true.
CC will say he can make them from a ham sandwhich wrapped in foil. Then he will show you a macro donut, much unlike Jones spheres.
Greening will mention fly ash but is unable to post content % of elements or present any other follow up research.
So although Jones' work is not conclusive, noone here has actually reproduced them or offer any supported explanation.
Oh and if Gravy were still here, he'd say that spheres just occur commonly in office fires. He'd then point you to one paper that he quote mined.
Oh, and others will say they are due to clean up and/or construction events. However elemental content of spheres created by cutting torches does not match those found in WTC dust.
So in the end, it is just a bunch of speculation for all sides, Jones included. But the fact remains, there is no decently supported explanation for the spheres found in the WTC dust by Jones, Lee report, and the rest.
