At What Temperature Does Paper Burn/Ignite/Combust?
Paper is said to burn at 451 degrees Fahrenheit (218 and 246 degrees Celsius), but the temperature at which it burns varies depending on the material, moisture, and thickness. Let’s take a closer look at the proposed paper burning temperature and see how it looks in the real world.
The Burning Temperature of Paper
Different types of paper may have significantly different numbers associated with them, and the age of the paper may also cause a variation in the burning temperature; however, unless you’re lighting a fire on the summit of Everest or at the bottom of the Marianas Trench, such differences are unimportant in most environments.
The heat of a naked flame is much higher than the auto-ignition temperature of paper, and most naked flames are already very hot. The hottest part of a flame is not the tip, but the slight “blue” aura surrounding it.
Ray Bradbury claimed that paper combusts at 451 degrees Fahrenheit in Fahrenheit 451, but modern evidence suggests that Bradbury’s Fahrenheit number is probably a little low. Old textbooks burn at around 481 degrees Fahrenheit, which isn’t a huge difference from Bradbury’s number. Most paper combusts at around 481 degrees Fahrenheit.
While a book may catch fire at 481 degrees Fahrenheit, it does not burn at that temperature; rather, it burns much hotter, similar to our naked flames.
Ignition Temperature Of Cardboard
Because the ignition temperature of “corrugated board” is much higher than that of paper, and because cardboard is a heavier, more dense material that can insulate against heat more effectively, choose cardboard over paper as an insulating material.
Cardboard has a flashpoint of 800 degrees Fahrenheit, while a cigarette has a flashignition temperature of 1,000 degrees Fahrenheit.
Paper auto-ignites at around 481 degrees Fahrenheit, but with the right conditions and fuel, it can reach temperatures of up to 1,500 degrees Fahrenheit, with nothing outside of the normal range when it comes to heat.

At what temperature do things catch fire?
The temperature of fire can range from around 400 degrees Fahrenheit to 9000 degrees Fahrenheit (200 to 4980 degrees Celsius), depending on factors such as fuel source and oxygen content; there are even “cold fires” that will not burn you.
What temperature does cardboard catch on fire?
To be safe, keep your heat at the recommended setting of 170 degrees Fahrenheit; if you want to crank it up a bit more, that’s fine. Cardboard doesn’t catch fire until temperatures reach over 400 degrees Fahrenheit.
Why did they burn books in Fahrenheit 451?
Fahrenheit 451 is a novel by Ray Bradbury published in 1953 (and soon to be adapted into a film) about a “fireman” who burns books rather than saves them in order to keep society illiterate and complacent.
What’s the hottest part of a fire?
The base of the flame is the hottest part, so it burns with a different color than the outer edges or the rest of the flame body. The hottest flames are blue, followed by white, and then yellow, orange, and red are the most common colors you’ll see in most fires.
At what temperature do things spontaneously combust?
A chemical reaction occurs when the temperature rises above 130u00b0F (55u00b0C), and it may continue without oxygen, but the flammable gases produced are at a temperature above their ignition point, and they will ignite when they come into contact with the air. Check your hay on a regular basis.
Can cardboard catch on fire from heat?
Cardboard can catch fire if it reaches a very specific temperature of 427 degrees, while most pizzas bake at or above 425 degrees, a two-degree difference that is a little too close for comfort. Newer ovens have better heating elements covered and circulate the heat, reducing the risk of fire.
Will cardboard catch on fire in the oven?
To cut a long story short, the safest option is to avoid putting any cardboard in the oven; even at the lowest temperature setting, there’s a risk of spontaneous combustion or fire.
Can I heat pizza in the box in the oven?
You can keep your pizza warm in the oven in two ways: in the box: don’t worry, pizza boxes won’t catch fire until they reach over 400 degrees; for this method, set your oven to the lowest temperature and slide your pizza onto the middle rack, still in its box.
At what temperature does paper towel burn?
It still burns easily in a hot environment, and because paper comes from trees, forest fires are common in the summer. Paper has an ignition point of 451 degrees Fahrenheit (or 232.778 degrees Celsius).
At what temperature does parchment paper burn?
Although most parchment paper is rated for temperatures between 420 and 450 degrees, we do occasionally recommend using this liner for bread and pizza baked at temperatures as high as 500 degrees.
What is the ignition temperature of kerosene?
 Kerosene, gasoline’s aviation counterpart, has a flash point of 100 degrees Fahrenheit and an auto-ignition temperature of 428 degrees Fahrenheit.
Do books actually burn at 451?
Bradbury’s title refers to the auto-ignition point of paper, which is the temperature at which it will catch fire without being exposed to an external flame. Bradbury claimed that “book-paper” burns at 451 degrees, and it’s true that different types of paper have different auto-ignition temperatures.
Is book burning still practiced today?
Book burning is one of the most extreme forms of censorship, suppressing opposing viewpoints to religious and secular authorities by ceremonially burning written text. Unfortunately, book burning has a long history, and the practice is still very much alive today, despite the ironic nature of what it accomplishes now vs. what it accomplishes in the past.
Why are books burned?
The deliberate destruction of books or other written materials by fire, usually in a public setting, is known as book burning. Book burning is a form of censorship that usually stems from cultural, religious, or political opposition to the materials in question.
