in regards to the creation of the spheres:
Still waiting for a comment on the molten concrete. Ignored all day so far.
The floors are vacuumed many times during construction. They must be free of dust before any flooring can be laid down. There might be some iron microspheres inside the columns but not anything close to 6% of the weight of the WTC dust.
There is no data on how many iron microspheres are created by welding so this (your) whole argument is pure wishful thinking.
I am abolutley positive, that someone here will try to say the spheres are fly ash from the lightweight concrete but fly ash is not always used and there is no evidence to establish that it was used during the construction of the Twin Towers. I await someone to post a link and disprove me.
The RJ Lee Group was crystal clear in stating:
iron and lead were melted during the WTC Event, producing spherical metallic particles
But allot of the posters over here at the JREF have a whole chapter on the RJ Lee report in your "Deniers Play Book" which is enough to waste a lot of time in a debate and fog the issues that should be debated - which is all you can do, but then, that's all that you need to do.....isn't it???
What none of you can dispute is the molten concrete...cmon dispute it!! Please!
Instead you will change the subject or go away and all of Morh's squires will descend upon me like a pack of rabid dogs.
the melting point of concrete varies between 1800-2500°C. (3272-4532 degrees F.)
