|
|
Now the molten metal seen dripping from the south tower seconds before collapse is for many damming evidence for the use of thermite. I suggest that we all try and dig up conclusive evidence that molten aluminum appears silvery gray in daylight at all temperatures. This post is not asking anything other than does aluminum glow orange in daylight when molten so please make your comments relevant. _________________ We check the evidence and then archive it: www.911evidencebase.co.uk

Well, it appears to glow red here:

That's at 1300F (around 700 Celsius in proper units).
Mind you, I thought the plane was finely divided and so there wouldn't have been enough aluminium alloy in one place to cause that much liquid.
Tip: For googling, they call it aluminum in the USA.
PS I think you mean damning evidence. |

That's always confused me somewhat. Debunking 911 quotes NIST -
Quote: | "NIST concluded that the source of the molten material was aluminum alloys from the aircraft, since these are known to melt between 475 degrees Celsius and 640 degrees Celsius (depending on the particular alloy), well below the expected temperatures (about 1,000 degrees Celsius) in the vicinity of the fires. Aluminum is not expected to ignite at normal fire temperatures and there is no visual indication that the material flowing from the tower was burning.
Pure liquid aluminum would be expected to appear silvery. However, the molten metal was very likely mixed with large amounts of hot, partially burned, solid organic materials (e.g., furniture, carpets, partitions and computers) which can display an orange glow, much like logs burning in a fireplace. The apparent color also would have been affected by slag formation on the surface."

But then just below has a graphic showing the plane getting shredded.
The infamous tower footage appears to show a fair old bit of metal. All melting at the same time and pouring from the same place. Whereas the graphic is hardly gospel, it illustrates what basically happened. I'm hardly an expert on such affairs, but would assume you'd need a pretty sizable chunk of metal to produce such a flow. _________________ It's a man's life in MOSSAD |

Here's some stuff I found although finding hard evidence that aluminum even at high temperatures does not glow is hard to come by. Remember Jones states that in low light conditions aluminum does give off a dim pinkish glow but always appears silvery gray in daylight whatever thetemperature. Of course we need the advice of experts on this as this is an important piece of evidence if it is true.
Quote: | Often, the metal's sensitivity to heat must also be considered. Even a relatively routine workshop procedure involving heating is complicated by the fact that aluminium, unlike steel, will melt without first turning red. Forming operations where a blow torch is used therefore requires some expertise since no visual signs reveal how close the material is to melting.

Well aluminum does appear silvery gray around 600c although we can't be sure of the temperatures of the fires. If the fires were around 600c then molten aluminum would indeed appear silvery.
This PDF seems to suggest that to measure the temporature of molten aluminum special equipment is needed because of it's low emissivity (I might email this company and ask for their opinion): http://www.mikroninfrared.com/literature/Aluminumbrochure.pdf

There were some silly posts here which have now been moved
http://www.nineeleven.co.uk/board/viewtopic.php?t=5970&start=60
I'd like to see explanations of why there is no "real" evidence of molten metal from anyone making such a claim please _________________ Free your Self and Free the World |

This is a capture from the CSPAN program on Alex Jones' symposium on 9/11 last year.
Steven Jones is holding up the sample of molten metal that he tested, which he confirmed was not molten aluminium.
I can post Steven Jones' segment from said Symposium if people need proof. |
