I find only that RDX is used in controlled demolitions. I can't find any link between thermite, or thermate and controlled demolition except on pages discussing 9/11.

Fed:Thermite nasty stuff, but like fertiliser has legitimate use
CANBERRA, Sept 23 AAP - The Anarchist's Cookbook describes thermite as nasty stuff and, like ammonium nitrate fertiliser which has been used to fuel car bombs, it has entirely legitimate uses.
Thermite is a mixture of powdered aluminium and iron oxide, or rust.
It burns at spectacularly high temperatures, as hot as 3,500 degrees Celsius, which is hot enough to melt steel.
That makes thermite particularly useful for welding. It is most commonly used to join the ends of railway lines.
Because the basic ingredients are so readily available, anyone with the inclination could produce their own thermite, aided by some very basic internet research.
However, it is relatively difficult to ignite and requires an ignition source much hotter that a cigarette lighter, for example.
Magnesium ribbon fuse appears to be the recommended method to ignite the substance.
There has been at least one workshop mishap in Australia where the use of a bench grinder produced the ingredients for a thermite reaction with the resulting fireball leaving the operator with serious burns.
Thermite is used in hand grenades and charges for military demolitions.
The US AN-M14 TH3 incendiary hand grenade contains about half a kilogram of a thermite compound called thermate.
I'm looking for an instance where it was/is used for controlled demolition. The latest theory basically claims that it is commonly used for the purpose, yet I don't find mention of that anywhere except in articles related to this latest theory.
Like I said, I just like to double check things. :)
Nor can I find any military or defense suppliers of thermite cutting charges (or lances or rods for that matter). For example, goto http://www.the-dma.org.uk/Products/main.asp?Start=T which lists defense products and if you scroll to "thermite cutting charges" and click you get no manufacturers found.
Now it may be that information on where to get "thermite cutting charges" has been supressed in recent years, and maybe the military gets their own made up special and outside GSA-procurment, but legitimate commercial applications ought to still be listed if there were any (similar to those for welding) but there seemingly are none.
I find this troublesome for the latest theories.
Agreed.
There seems to be a lot of hypothetical presumption about "thermite cutting charges" and I've looked for the BYU professors paper on his thermite research and findings but it doesn't seem to be available yet (I don't mean his general paper http://www. physics.byu.edu/research/energy/htm7.html but supposedly he has a newer paper specifically "proving" the use of thermite). His general chemistry & physics seem to be in order, assuming "thermite cutting charges" are real items available commercially or militarily, but as mentioned above, I can't find any.
My simple understanding of the thermite reaction is that it is difficult to ignite and its reaction rate is not precisely controllable, which would seem to make it unreliable for controlled demolition wherein the timing of cutting through support beams and columns must be thorough and exact to a second or two, otherwise the structure won't collapse as planned. As the thermite reaction is also a slower burning rather than an explosion, it's cutting direction is downward where ever gravity pulls the 'molten thermite' (see http://www. amazingrust.com/Experiments/how_to/Thermite_pics-videos.html) which means making thermite cut laterally across vertical support columns (orthogonal to gravitational pull) instead of dripping/running down the sides would seem to add great difficulty to controlled demolition.
While "thermite cutting charges" provide plausible explanations for some of the WTC collapse phenomena, it also introduces some new complications, namely procurring said charges, installing them, and triggering them precisely. Whereas regular demolitions are procurable and triggerable, but still need to be placed/ installed without notice.
Dr Jones`s papers are multi peer reviewed. Thermate cuts like butter. Very fast. Placed at an angle, not flat, will slice girders. It is ignited by electronic "matches". This whole opp was radio/computer run.
Thermate doesn`t explode, but nano thermite does. Very powerful. How else can oe explain pools of molten iron, metal and some copper. It takes around 4000 degrees for this.
Thermate cuts like butter. Very fast. Placed at an angle, not flat, will slice girders.
Ok, so assuming a "thermate" cutting charge is somehow beaded around a vertical girder with the side beads running downward at an angle and the top and bottom beads run horizontal, upon ignition, what prevents the molten thermate from dripping down the vertical exterior faces of the girder and/or what causes the molten thermate to cut horizontally into the girder?
Even a bead placed at an angle, upon melting will drip down from its original angular bead along the exterior face of the girder. Gravity will not carry molten thermate horizontally from the bead into the girder to make the cut.
Oh, there was dripping and running of iron by-product down the girders. This thermate takes seconds. One is not using a stop watch. A couple blinks of an eye, and its through. The sulfur mix is the key. It just eats steel up.
Dr. Jones has pictures of this molten iron that is like stalactites and in other photos hanging down horizontally like a giant blob.
You have to remember as these girders were cut through with thermate, other explosives were taking out other supports, which placed more stress, weakend and severed the beams.

How did gravity carry molten thermite horizontally to cut into a vertical girder instead of dragging the molten thermite vertically down the exterior face of the girder?
You are under the impression that gravity is needed for thermate to work. This is not the case with the sulfur mix. Dr. Jones work, I believe, shows this.
I know that you are trying to put forth a middle, unbiased view. I wish others like yourself, would questioned the government theory as hard.

Not chemically, but gravity is what keeps the molten thermite in contact with the surface it is to cut or weld. If you don't believe that, what prevents the molten thermite from cutting sideways or upwards out its crucibles or molds? Why does it always cut and/or melt what is below it?
All the videos of thermite and the applications of welding rely upon gravity to pull the molten thermite down onto the target or into the weld joint sealed with a mold around it (such as the railroad rail welding applications). Even the torches and lances rely upon a continued supply of newly molten thermite held against the cut by the technician.
This is not the case with the sulfur mix.
I don't see how sulfur changes the gravitational problem posed. A faster hotter reaction does not change the rate at which gravity pulls it downward. Which falls faster - a molten 1lb brick or a frozen 1lb brick? It still does not address directing the molten thermite/thermate horizontally for "several" seconds into a girder that is several inches thick, rather than flowing down the face of that girder.
Dr. Jones work, I believe, shows this.
Dr. Jones has only shown the exothermic reaction explains some of the chemical and thermal phenomena. The paper in which he claims to have proven this ostensibly is undergoing peer review and has not been published yet. At least I have not seen it. So no, to the best of my knowledge Dr. Jones has not (yet) shown how thermate/thermite would be applied and controlled to cut in the direction needed.
Chemically is the key. This sulfur mix is not only faster and hotter, it reacts with the steel and eats it up. Comparing welding techniques to this just can`t be done. Hopefully soon, Jones will put out his findings.
How would you then explain the pools of iron at all 3 buildings?
This sulfur mix is not only faster and hotter, it reacts with the steel and eats it up.
Only as long it remains in contact with the surface, ie until gravity pulls it away.

Well, thermite welding techniques do illustrate how/why thermite works to cut/ weld anything below it. But you're right insofar as there is no "thermite cutting charge" information against which to compare or apply to the current problem of cutting very thick vertical girders.
How would you then explain the pools of iron at all 3 buildings?
I don't have an explanation, nor have I read one that seems to fit all the facts, including the government's version. You wrote earlier to me:
I know that you are trying to put forth a middle, unbiased view. I wish others like yourself, would questioned the government theory as hard.
I'm simply following where the actual data available leads, no more, no less. I have no qualms about questioning the government's theory or anyone elses.
It's hard to imagine where and how thermate would be usefull in bringing down a building like this, if you're not looking at the actual naked structure. So, I found a good view of the naked structure. :)
BTW, a follow up thought regarding what I'd like to see from Professor Jones in "proof" beyond a simple thermo-chemical analysis that thermite/thermate was employed:
4.4 Core columns Inside each tower there were 44 large, concrete reinforced, steel columns, which enclosed elevators, stairways, and utility space. Again, the author's inquiries to ascertain exact values for the core column dimensions failed. However, one is able to estimate these values by comparing the size of core columns to the size of exterior columns as captured in photographs of the site, such as the one shown below. With an accuracy compromised by the poor resolution of the photographs available, we determined that each column had a thickness of 67mm, and dimensions of 950mm x 312mm in rectangular cross section.
The problem with those dimensions (beyond being an unofficial estimate) is that IIRC the cross section of columns varies from thicker to thinner progressing upward in the building and hence I would expect the estimate may not be true for all floors throughout the towers.
So I would hope to see in such a proof:
a definitive statement on the cross section dimensions of the various support columns,
what kind of steel they were made from and its properties, and then
how much thermite/thermate is required to burn through steel girders of that type and cross section and
how long that takes, and then
how is gravity counteracted such that the required amount of molten thermite/thermate is kept in physical contact with the 'cut' for the required burn-through time,
how is it ignited,
how is the ignition of M columns x N cuts coordinated throught the building such that a 'controlled demolition' kind of collapse can be produced.
...concrete reinforced, steel columns, which enclosed elevators, stairways, and utility space.
If this is true, you've uncovered something that no one is saying. There was CONCRETE and steel reinforced elevators, stairways and utility areas. This would be big news in favor of explosives. How would the government explain a "pancake" and core/truss failure by fire?
Can I use that link? I'm going to bring it over to the Loose Change Forum.

I wouldn't know. I don't track this stuff.

I don't know how much of the support structure is steel reinforced/encased by concrete, but the presence of steel-reinforced concrete is a complication for the thermite/thermate theory in that the thermite/thermate has to burn through concrete first to get to the steel.
I thought I would drop you a quick update. I heard Dr Jones on a radio show very recently and the two types of applications they believe were used of the themate/thermite were in a sol-gel that can be used in either form of a nano-thermite explosive or cutter thermate. The other is a cylinder shape cutter that has a groove/slit that directs the thermate like a knife or laser and needs no gravity.

Thanks very much.
Those help to explain how such a cutter charge would be planted (as thermite/ thermate is is fine powder that would otherwise blow or fall away).
But once ignited, the thermite/thermate melts and liquifies as it burns and I would think gravity would pull the molten thermite/thermate out of the cut and down the face of the beam instead of across and horizontally through the cut.
If you run across an explanation of how such charges would cut horizontally (against gravity) through several inches of metal, or even a video demonstrating an experimental charge cutting horizontally, I'd appreciate another ping.
But once ignited, the thermite/thermate melts and liquifies as it burns and I would think gravity would pull the molten thermite/thermate out of the cut and down the face of the beam instead of across and horizontally through the cut.
I don't follow where you're going with this. Why do you presume molten thermite/thermate ran horizontally across the face of a beam? Video evidence is available which shows a molten liquid substance pouring out a window - and dropping down - one of the towers before it collapsed.

I don't assume that. I said:

So, I would expect molten thermite to run down the beam, instead of cut horizontally through it.
But to actually do the job of cutting horizontally across/through the beam (which is vertical), the "molten thermite" would have to defy gravity so to speak, and not flow down but instead flow across deeper and deeper into the cut.
