Pans are typically rated with a temperature limit, such as oven-safe up to 500°F, despite a burner flame being capable of producing much higher temperatures. This is because a significant amount of heat energy is lost during transmission to the pan, and the pan itself constantly emits heat energy into the environment. Additionally, the pan's handle, which is often made of plastic or wood, can be a limiting factor as it cannot withstand high temperatures. However, it is important to note that the actual temperature of a pan can be higher than the heat source due to various factors, such as the material and design of the pan. For example, an aluminium pan may reach a higher temperature than a stainless steel/aluminium pan when placed on the same burner due to differences in volumetric heat capacity and thermal conductivity. Properly preheating a pan is crucial to prevent food from sticking and achieve the desired cooking results.

What You'll Learn
Pans with plastic parts can melt at high temperatures
Pans can be heated to temperatures higher than 570°F. For instance, a pan on a burner set to 400°F can reach a surface temperature of about 700°F. This is because a pan made of aluminium will absorb heat and keep climbing. However, this violates the second law of thermodynamics, as heat flows from a higher temperature to a lower temperature.
If plastic melts onto a pan, it is possible to remove it without damaging the pan. One method is to place the pan in the freezer for 3 to 5 hours, allowing the plastic to harden. The pan can then be removed from the freezer and gently struck with a soft, heavy object, such as a wooden spoon or plastic mallet, to dislodge the plastic. Another method is to use a butter knife to scrape off as much plastic as possible, followed by boiling water with baking soda, and then washing the pan with soap and cold water. It is important to thoroughly clean the pan before using it again.
To avoid melting plastic on pans, it is recommended to always check the temperature specifications of the pan and ensure that it is safe for the intended use. If a recipe calls for a higher temperature than the pan can withstand, it may be necessary to adjust the temperature or use a different pan.
Additionally, proper preheating of a pan can prevent food from sticking. This involves heating the pan thoroughly before adding any oil, butter, or food. A surface thermometer can be used to help regulate the temperature, although experience with a particular stove and cookware will also build confidence and skill in achieving the desired temperature.

Pans with non-stick coatings can burn at high temperatures
Pans with non-stick coatings are not designed for high heat. Higher temperatures will damage the coating over time, and high heat can also cause the release of harmful toxins, depending on the type of coating on the pan. For example, PTFE-based non-stick pans, which make up the vast majority of non-stick coatings, will undergo pyrolysis at high temperatures, during which some of their fluorine compounds vaporize. This can be harmful to your lungs and can even kill birds.
Non-stick pans should not be preheated without food in them. They should always be started at a lower temperature using a fat like oil or butter or with the food already included. Empty pots and pans reach high temperatures very quickly, and when heated above 348 °C (660 °F) or 500 °F/260 °C, the coating can begin to deteriorate. Higher temperatures can also discolor the surface of the coating or cause it to lose some of its non-stick properties.
To properly heat a pan so that food won't stick, it is important to preheat the pan thoroughly before adding anything to it. This should take around 5 to 8 minutes. With experience, you can do this quicker, once you know your stove and cookware and how they react with each other. It is also important to use a stove burner that matches the size of the pan bottom.
It is worth noting that some claims have been made that certain non-stick pans can withstand higher temperatures without losing their non-stick properties. For example, GreenPan claims that their non-PTFE non-stick pans can withstand temperatures up to 850 °F. However, these claims have not been verified by independent authorities.
Therefore, it is generally recommended to avoid using non-stick pans at high temperatures, as they can burn and release harmful toxins.

Pans can reach higher temperatures than their heat source
Pans can reach a higher temperature than their heat source, but only under certain conditions. The claim that a traditional aluminium non-stick pan placed on a burner set to 400 degrees Fahrenheit will reach a surface temperature of about 700 degrees Fahrenheit is false. This would violate the second law of thermodynamics, which states that heat flows from a higher temperature to a lower temperature. However, it is possible for a pan to reach a higher temperature than its heat source if work is also done on the pan or if there is a mass transfer of hot material into the pan.
The rate at which a pan's temperature rises depends on its volumetric heat capacity and thermal conductivity. Volumetric heat capacity refers to the amount of heat needed to raise one unit of volume of an object by one unit of temperature. Pans made of different materials have different volumetric heat capacities, with aluminium having a lower volumetric heat capacity than stainless steel. This means that it takes less heat to raise the temperature of an aluminium pan by one degree than it does for a stainless steel pan.
Thermal conductivity refers to how quickly heat is transferred to a pan. Aluminium has a higher thermal conductivity than stainless steel, so heat will transfer more quickly to an aluminium pan. As a result, an aluminium pan will reach a higher maximum initial temperature than a stainless steel pan if the temperature of the heat source rises too quickly before reaching its equilibrium temperature. This is known as an "overshoot". However, once the heat source reaches its equilibrium temperature, both pans should settle at the same temperature.
To prevent pans from overheating, it is important to heat them correctly. This includes preheating the pan thoroughly before adding any food, oil, butter, or other fats. Preheating a pan properly can also prevent food from sticking. It is also recommended to lower the heat before adding oil or other fats to avoid overheating and destroying the coating of the pan.

Pans with a temperature limit of 500°F are common
It is important to note that the pan's temperature will not exceed that of its heat source. For example, a burner set to 400°F will not cause the pan to reach a temperature of 700°F, as claimed in some cookware advertisements. This would violate the second law of thermodynamics, which states that heat flows from a higher temperature to a lower temperature.
When using a pan with a temperature limit, it is crucial to follow the manufacturer's instructions and not exceed the specified temperature. Exposing the pan to higher temperatures can damage the pan and release toxic fumes. If a recipe calls for a higher temperature than the pan's limit, it is recommended to use a different pan or adjust the oven temperature accordingly.
To prevent food from sticking to the pan, proper preheating is essential. A lukewarm pan can cause food to stick, while a properly preheated pan will allow the moisture in the food to wick away, creating a slip and slide effect with the fat added to the pan. Preheating a pan thoroughly usually takes around 5 to 8 minutes, and a surface thermometer can be used to help regulate the temperature.
In summary, pans with a temperature limit of 500°F are common due to the presence of plastic or wood handles and non-stick coatings that cannot withstand high temperatures. It is important to follow the manufacturer's instructions and use alternative pans or adjust oven temperatures when necessary. Proper preheating and the use of surface thermometers can help prevent food from sticking to the pan.

Pans should be preheated thoroughly before cooking
It is important to preheat your pan thoroughly before cooking to prevent food from sticking to the surface. When a pan is properly preheated, the moisture in the food evaporates, and the fat that you add to the pan allows the food to move around easily. A lukewarm pan will cause the food to stick. This is especially important for delicate foods such as lightly breaded crab cakes, crepes, omelets, or duck breasts.
To preheat your pan, you can use a surface thermometer to monitor the temperature. Place the thermometer in the center of the pan and turn on the heat. It is recommended to start with a lower temperature than you think you need and gradually increase it to achieve a steady temperature. This may take some time and practice, as you will need to learn how your stove, cookware, and chosen temperature interact with each other. Once you have mastered this, you will be able to cook with more consistency.
If you do not have a thermometer, you can heat your pan for 5 to 8 minutes, or until a droplet of water skitters or sizzles across the surface. This will depend on the type of stove you have, as an electric stove may be damaged by heating a pan for too long. You will eventually be able to tell when a pan is ready by the way the heat shimmers off the surface.
There are some exceptions to preheating your pan. When rendering the fat from meat with skin, such as chicken thighs or duck breasts, you should use a cold pan and slowly increase the temperature. This is also true for cooking bacon and caramelizing onions, as a slow increase in temperature allows the water to cook off before the food begins to burn.
