The fact that the autoignition point of paper popularized from Fahrenheit 451 is incorrect. The actual autoignition temperature is 450 degrees Celsius, about 842 degrees Fahrenheit. This data from Handbook of Physical Testing of Paper, By Jens Borch, Richard E. Mark, M. Bruce Lyne.
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. [1]
On inquiring about the temperature at which paper would catch fire, Bradbury had been told that 451 °F (233 °C) was the autoignition temperature of paper. [30] [31] In various studies, scientists have placed the autoignition temperature at a range of temperatures between 424 and 475 °F (218 and 246 °C), depending on the type of paper. [32] [33]
A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.
The flash point of a material is the "lowest liquid temperature at which, under certain standardized conditions, a liquid gives off vapours in a quantity such as to be capable of forming an ignitable vapour/air mixture". [1] The flash point is sometimes confused with the autoignition temperature, the temperature that causes spontaneous ignition.
Euro paper banknotes can be made fireproof. The fireproof banknote is a demonstration of putting a banknote , previously soaked in 50% ( v/v ) alcohol fuel solution, to a flame . The fire is lit and later extinguished by itself without the banknote being burnt. [ 1 ]
Such measurements often use a standard temperature of 25 °C (77 °F; 298 K) [citation needed]. This is the same as the thermodynamic heat of combustion since the enthalpy change for the reaction assumes a common temperature of the compounds before and after combustion, in which case the water produced by combustion is condensed to a liquid.
Char cloth, also called char paper, is a material with low ignition temperature, used as tinder when lighting a fire. It is the main component in a tinderbox.It is a small swatch of fabric made from a natural fibre (such as linen, cotton, jute etc.) that has been converted through pyrolysis.
