Wrong!
The molten metal was 4500[FONT="]°[/FONT]F to begin with, insulation and burning debris in the pile slowed the cooling.
Really. And you think this would have stopped solidification of the steel (and other metals and materials that have melting points below 4500°F) after weeks?
Please show how you have come to this conclusion. You are going to have to show your working. Include the localised debris pile temperature, the volume of melted steel and the rate of cooling of this steel in your calculations. Could you calculate the heat loss per minute from 1kg of liquid steel at 2500°C to air at 20°C - assume what ever area of the steel and other dimensions you like.
Lurkers: also note how he says "molten metal" again and not "molten steel" or indeed liquid steel.
It's now that we get to the meat of what C7 actually claims.
He claims that thermite melted some of the steel beams/columns/etc in the towers - fair enough. After the melting, but before the collapse this liquid steel did not solidify. The impeccable timing of the cutting devices throughout the structure meant that collapse was initiated before any liquid iron and steel could solidify, even though thermite is not a material that is exact enough to time anything due to it's nature. (just witness videos of thermite being used to see this). It's not instant and parts of the structure as well as the iron produced from the reaction would start to cool before the cutting was completed.
Nor was it distributed amongst the debris and lower Manhatten (unlike the unburned thermite that Jones claims) just like every other part of the WTC, but it all magically gathered up together and remained liquid in a few places. Fancy that eh? An enormous collapse didn't have any detrimental effect on the state of this liquid steel, nor where it ended up! Then heat from the piles along with insulation managed to keep these parts liquid, after it had all magically combined after the collapse!
We don't know how many columns or beams were cut via this method, nor do we know how much liquid steel and liquid iron was produced via thermite, but what we do know is that it all came together in several places or indeed just one place and continued to be liquid through-out the collapse and weeks later due to underground fires (which were below the melting temperature of steel) and insulation (which we have no way of determining). Mmmmn. Confused.com? (don't go there it's a price comparison webshite).
The thing is I've used high temperature furnaces - in 1994/95, I had one operating at 1200 and 1400°C as part of a university project. I've heat treated various steels, in various furnaces, in various jobs whereby 1000-1100°C was common for homogenisation (and subsequent quenching to martensite etc) and carburising and nitriding (and sometimes carbo-nitriding in biiiig computer controlled envirements). I know how long it takes for a very well insulated furnace to drop from these temperatures to lower ones. Hell look up the phrase "furnace cool" as applied to "heat treatment" and you'll get an idea.
When going from a temperature of 1400°C to 1000°C you don't turn off the furnace, you merely set the thermostat for 1000°C (and monitor with your thermocouple). The furnace will increase the heat before the temperature gets to 1000°C and steady down. Remember that the furnace is as well insulated as it could be. This would take about 4 hours. (the actual heated part was a long alumina tube about 4ft long and 4in in diameter) with the whole thing being roughly 6ft long 3 1/2 feet wide and 5ft tall and you couldn't take the end bung out to accelerate the cooling. (Amusing to see friends read the temperature and then watch me take out SiC samples and handle them about 30 seconds after they came out of 1400°C!)
