Does paper burn in the oven? Understanding the Risks

does paper burn in the oven

We often use parchment paper to prevent food from sticking to the pan. But the question arises: does paper burn in the oven?

Yes, paper can burn in the oven and even catch fire if you are not careful. However, oven-safe parchment paper may darken in the oven, but it won’t catch fire.

It is important to understand that the temperature at which paper burns in an oven depends on the type of paper, its thickness, and how quickly the oven is heated. Most papers will burn at around 250 degrees Fahrenheit. Therefore, it is crucial to keep the temperature between 400 to 450 degrees F when using parchment paper to avoid the risk of fire.

What is Paper Made of?

Paper is a thin material made from wood pulp, rags, or other fibers. It is used for writing, printing, and packaging. The exact composition of paper varies depending on the type of paper and the intended use. However, most paper is made of the following components:

Cellulose fibers

Cellulose fibers are the main component of paper. They are long, thin, and flexible fibers that provide strength and structure to the paper. Cellulose fibers come from wood pulp or other plant materials. The fibers are separated from the other components of the plant and then processed to create pulp.


Fillers are added to the paper to improve its properties. They can be natural or synthetic materials. Common fillers include clay, calcium carbonate, and titanium dioxide. Fillers improve the opacity, brightness, and smoothness of paper.

Sizing agents

Sizing agents are added to the paper to control its absorbency. They prevent the paper from absorbing too much ink or water. Sizing agents can be natural or synthetic materials. Common sizing agents include starch, gelatin, and rosin.


Additives are added to paper to improve its properties. They can be natural or synthetic materials. Common additives include dyes, pigments, and fluorescent brighteners. Additives improve the color, brightness, and whiteness of paper.

Heat and Combustion

The Science of Burning

The science behind it is quite simple. Combustion is a chemical reaction that occurs when fuel (in this case, paper) reacts with oxygen in the air. This reaction releases energy in the form of heat and light, which can cause the paper to catch fire.

The temperature at which paper burns depends on various factors, including composition, density, and shape. In general, paper will start to char, turn brown at around 425°F to 481°F and ignite and burn at higher temperatures.

What Happens When Paper Burns?

When paper burns, it undergoes pyrolysis, which is the thermal decomposition of organic materials in the absence of oxygen. As the paper heats up, the cellulose fibers that make up the paper begin to break down and release volatile gases, such as water vapor and carbon dioxide.

As the temperature rises, the gases ignite and burn, releasing more heat and light. The remaining solid residue is called char, a black, carbon-rich material left behind after the volatile gases have burned off.

Note that paper will not burn without oxygen being present. Oxygen is necessary for combustion, as the oxidizing agent reacts with the fuel to release energy. Without oxygen, the paper will decompose and turn brown to black as the cellulose polymer degrades.

Oven Temperatures and Paper Ignition

Paper burns most easily in areas with high heat and oxygen levels. If our oven is set on the highest setting and the paper is placed on top of the heating element, it could catch fire. This is because paper ignites at around 218°C (425°F) and can continue to burn until completely consumed.

Different types of paper have different ignition temperatures. For example, wax paper is not heat-resistant like parchment paper. When exposed to prolonged, high heat, it will melt, and the paper can easily catch fire.

Factors that Affect Paper Combustion in the Oven

When using paper in the oven, several factors can affect its combustion. These include:

  • Oven temperature: As mentioned earlier, paper burns most easily in areas with high heat and oxygen levels. So, if we set our oven to a very high temperature, the paper is more likely to ignite.
  • Paper type: Different types of paper have different ignition temperatures. So, using oven-safe parchment paper rather than wax paper when baking in the oven is important.
  • Placement: If we place the paper too close to the heating element or on top of a hot baking sheet, it is more likely to ignite.
  • Duration: If we leave the paper in the oven for too long, it can start to darken and eventually catch fire.

What to Do if Paper Catches Fire in the Oven?

Safety Precautions

Here are some safety precautions that we should follow:

  • Turn off the oven immediately to prevent the fire from spreading.
  • Please do not open the oven door; this will only provide oxygen to the fire and worsen it.
  • Keep a fire extinguisher nearby and know how to use it in an emergency.
  • Avoid using water or any other liquid to put out the fire, as this can cause the fire to spread or create an electrical hazard.

Steps to Take When Paper Catches Fire in the Oven

If you notice that paper has caught fire in the oven, follow these steps to minimize the damage:

  1. Keep the oven door closed and turn off the oven immediately.
  2. If the fire is small and contained, use a fire extinguisher to put it out. Aim the extinguisher at the base of the fire and sweep back and forth until the fire is out.
  3. If the fire is too large or you cannot put it out with a fire extinguisher, call the fire department immediately and evacuate the area.
  4. Once the fire is out, allow the oven to cool before removing burnt paper or debris.
  5. Clean the oven thoroughly to remove any remaining ash or residue.


Based on our research and the information gathered from various sources, we can conclude that paper can burn in the oven, depending on the type of paper, its thickness, and the temperature.

Keep the temperature between 400 to 450 degrees Fahrenheit when using parchment paper to prevent it from catching fire. Monitoring the oven while baking or cooking is crucial to avoid any potential hazards.

Suppose you plan to bake or cook with paper. In that case, we recommend preheating the oven to its cooking temperature and baking the paper for a few minutes before removing it. This will help ensure that the paper does not catch fire and that your food is perfectly cooked.

FAQs – does paper burn in the oven?

Can I Use Any Paper In The Oven?

No, not all types of paper are safe in the oven. Regular paper, newspaper, and wrapping paper are unsafe in the oven. They can easily ignite and cause a fire. However, if used correctly, parchment paper and wax paper are safe to use in the oven.

What Is The Maximum Temperature That Parchment Paper Can Withstand?

Parchment paper can withstand temperatures up to 450 degrees Fahrenheit without any problems. However, it is left in the oven for too long at a high temperature. In that case, removing the food from the paper can darken and become difficult.

Can I Use Parchment Paper In A Toaster Oven?

You can use parchment paper in a toaster oven, but you must ensure the paper does not touch the heating elements. Following the manufacturer’s instructions for your toaster oven is also important.

Can I Use Aluminum Foil Instead Of Parchment Paper?

Yes, you can use aluminum foil instead of parchment paper, but there are some things to remember. Aluminum foil does not have the non-stick properties of parchment paper, so you will need to use cooking spray or oil to prevent sticking. Additionally, aluminum foil can react with acidic foods, so it is not recommended for use with these foods.

Is It Safe To Use Paper Towels In The Oven?

No, it is not safe to use paper towels in the oven. Paper towels are not designed to withstand high temperatures and can easily catch fire. If you need to absorb excess oil or grease from your food, use a clean kitchen towel or a paper towel outside the oven.

Can I Use Brown Paper Bags In The Oven?

No, using brown paper bags in the oven is unsafe. Brown paper bags are not designed for use in the oven and can easily catch fire. If you need to cook food in a paper bag, use parchment paper instead.
