I do note that your temperature curves are based on underground fires... you dont get alot of airflow in one of those.
Subways.

The stream of liquid coming out of the side of the building is debatable. It is possible it is aluminium.
The argument that aluminium does not glow bright is one of strong ignorance as it definitely does, it can get as bright as any molten metal, and is almost white when near boiling temperatures.

probably molten lead - that floor had the backup batteries

Aluminium has an extremely low melting temperature of 1200 in comparison to the other metals that melted in that building on that day. If office fires alone can reach 1400, then what does this tell you? In a normal office fire we can expect to see molten aluminium. With me so far?
What happens to aluminium when you pass it's base melting temperature and start to climb towards its boiling temperature?

So why do you think the aluminum posted above appears silvery?

Then you start reaching temperatures that would be absurd for a hydrocarbon fire

Now here is a point I wouldn't even try and challenge. I think we both agree these temperatures far exceeded a hydrocarbon fire.

You are using the color of aluminium (or lead) at its minimum melting temperature in a debate where you have already admitted the heat had to have been far greater. This defeats itself.
You have already answered this question: What color is aluminium when it is melted?
You need to answer this: What color can aluminium turn if you continue to heat it past being melted?
When you have answered this question, this debate can move forward.

Then just to be clear, you agree this molten material wasn't caused by the fires? Because they were hydrocarbon fires. Those fires max out around 800 C in perfect conditions and flashover temperature (which is only brief combustion of gases, rather than the hydrocarbons, that collect near the ceiling from combusted materials) is around 1000 C or so. And those aren't the temperatures the metal would have been, because the metal is always heated to a temperature less than the actual temperature of the fires. That's thermodynamics for you.
