1. Your above quote/comment implies a possible "tolerance" of their paper. You have shown me no proof of "Ok"ing the paper, which implies they endorsed it.
I don't mean to imply that BYU endorses the thermite paper, only that they know of it, do not object to it, and
OK'd Dr. Farrer and Daniel Farnsworth to list their affiliation with BYU.
You have provided a quote where they expand upon what vaporizing meant, and what the evidence might show if this were the case. You have not provided any evidence that they found evidence of vaporized lead...sorry, try again.

A variety of analytical techniques were applied to characterize the surface
chemistry of WTC materials. These analytical techniques included scanning
electron microscopy/energy-dispersive spectroscopy (SEM/EDS), X-ray
microprobe, and X-ray photoelectron spectroscopy (XPS). The SEM and
microprobe techniques provided details that sparked interest in a closer look
at the surface characteristics. XPS is a surface analysis technique that not
only can detect most of the elements of the periodic table, but can also
determine their oxidation state or binding energy. Thus XPS can provide
chemical species information for elements. XPS is capable of analyzing
components in the top 100 angstroms of surface. Because of the sensitivity to
surface components, XPS is highly useful in the characterization of chemistry
of the surface of the dust particles.
The XPS results indicate the presence of a thin contaminating film or coating
associated with the surface of particles. These surface species could be a
significant factor affecting the toxicity of the WTC Dust if the coatings on
particles and fibers are composed of hazardous substances. The coatings
vary in thickness from nanometers (monolayer) to finely dispersed sub-
micron particles. The particles and coatings have been detected by low
accelerating voltage back-scattered electron imaging, X-ray microprobe
analysis, and high resolution XPS. For example, lead peaks from the surface
of mineral wool were identified by XPS. The high-resolution, narrow-range
XPS scan (Figure 25) led to the identification of two lead peaks representing
lead oxide or lead sulfate.
The presence of lead oxides on the surface of
mineral wool indicates the exposure of high temperatures at which lead
would have undergone vaporization, oxidation, and condensation on the
surface of mineral wool. In addition to the trace amounts of lead, Table 2
indicates the presence of carbon, nitrogen, oxygen, sodium, silicon, sulfur,
chlorine and calcium on the surface of the mineral wool.
