all things burn at different temperatures, that temp is call the flash point

Well, an object radiates more heat the higher temperature it has, but the business of confining it inside a fireplace or a pit reduces the ability of the heat to escape. Consequently, there's an upper limit on how hot the fire can get, yes -- but often times the size of the fire dictates how hot it can get at its center. What you ought to do is build a replica firebox out of a non-combustible material (maybe just use surplus construction bricks or cinder blocks), lay the fire, and then use an infrared / laser thermometer (I'm sure you can borrow or rent one) to check the temperature at the core of the fire. Repeat a few times and then you'll have a sense of how hot the fire can get. If your insulating material protects against this upper limit, plus a reasonable buffer (maybe 20% or so) then you'll be sure it'll protect against this temperature. However, once you build the actual fire box, you'll want to check that the outside temperature stays sufficiently low (and/or there are no combustible materials remotely near the thing).

Answer 4

Color tells us about the temperature of a candle flame. The outer core of the candle flame is light blue -- 1670 K (1400 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange and finally red. The further you reach to the center of the flame, the lower the temperature will be. The red portion is around 1070 K (800 °C). The reason there is this variation in a candle's flame color is because air convection pulls the warmer gasses upwards.

Candle flames behave differently in outer space (microgravity) than they do on Earth. The primary reason for this difference is that microgravity provides an environment that lacks buoyant convection, which normally plays an important role in maintaining and shaping a flame on Earth. In Earth's gravity, buoyant convection develops when hot, less dense combustion products rise. The flow that results draws cooler surrounding air to the base of the flame, supplying it with the oxidizer (in this case, oxygen) that the flame requires to maintain itself. Combustion products (carbon dioxide, water vapor, and soot) are carried away from the flame by the same convective flow, which is the dominant transport mechanism in the flame.

Answer 5

Depends.

Some alcohols will burn with a flame as "cool" as 150 degrees F, while the fires of nuclear fusion in the sun burn at millions of degrees.

Here's a short list from Wikipedia:
- Oxyhydrogen Flame (2000 °C or above)(3645 °F)
- Bunsen Burner Flame (min. to max. setting) (1300 to 1600 °C)(2372 to 2912 °F)
- Blowtorch Flame (1300 °C)(2370 °F)
- Candle Flame (760 °C)(1400 °F)
Lit cigarette:
-Temperature without drawing: Side of the lit portion; 400 °C (or 750 °F);Middle of the lit portion: 585 °C (or 1110 °F)
-Temperature during drawing: Middle of the lit portion: 700 °C (or 1290 °F)


Paper is supposed to ignite at 451 °F

Answer 6

Depends on what's burning darling. Varies a lot.

Answer 7

It really depends on what's burning. Different materials have different flashpionts.

Answer 8

1500 to2000 c
