Database: Fire heat/temperature estimation

Sometimes we want to calculate the heat or temperature of a fire
or explosion. This is a common and very useful calculation type,
and there are several methods.
Color:
To estimate temperature by color, just see what color the flame
is. Then take a look at a flame color chart like this one

/>
This method is very simple but also somewhat unreliable
(usually only perhaps 7/10). Flame color charts sometimes differ
a bit from each other—this one

/>is slightly different from this one

Destruction/melting:
This is essentially the same as the Destruction Method

/>for explosions. There are a couple ways to approach it:
[list type=decimal]
[li]You can look at how many kg of a given substance it
melted/vaporized. For how to do this, click here

[li]Use this method
HTML https://sciencing.com/calculate-joules-heat-8205329.html:
heat
(in joules) = mass of object (in kg) × change in temperature (in
Celcius) × specific heat capacity of material (in kJ/kg K). It
is superior to the first for smaller levels of destruction.[/li]
[/list] However, the destruction/melting methods only give
answers for heat, not temperature.
