The glow was from the crucible, not the metal. It is also a generous statement that the fire could have reached 1800°F but hay, while experts point out it is a high number they let them have it. There are still problems with the claims.

The people who developed the theories of the collapse said those theories needed to be proved. They weren’t. Their own models had to be modified and those things they tried to have independently verified failed, yet they still would not revise the reports.

I fear you are woefully misinformed if you think the hard science and physics favours the reports.

Occam's razor just happens to be on the side of the people you term truths.
