Q. At what temperatures do forest fires burn?
An average surface fire on the forest floor might have flames reaching 1 meter in height and can reach temperatures of 800°C (1,472° F) or more. Under extreme conditions a fire can give off 10,000 kilowatts or more per meter of fire front. This would mean flame heights of 50 meters or more and flame temperatures exceeding 1200°C (2,192° F).
This is much hotter than the melting point of aluminum which is under 1,300° F
Moreover, the adiabatic flame temperature of wood burning with air is 1,980 C (3,956 F). Plenty of capability to melt things. How do you think we melted things in ancient times? Atomic power?

What temp do desert fires burn
Gold melts at roughly 2000 degrees Fahrenheit. That’s hot.
