Air Frying Polymer Clay: Does It Work?

Yes, it is possible to cure polymer clay in an air fryer. Air fryers circulate hot air around the food to cook it, acting like a small convection oven. Convection ovens are ideal for curing polymer clay as they prevent hot spots from forming, which could darken the clay. However, there are some potential issues with using an air fryer for this purpose. Firstly, air fryers may not have a low enough temperature setting for curing polymer clay. Secondly, lightweight clay pieces may blow around due to the strong fan, and the vapourised oil emitted from the clay could build up on the walls of the air fryer. It is recommended to test the air fryer on a small sculpture first and to use an oven thermometer to ensure the correct temperature is reached.

Air fryers are a viable option to cure polymer clay

Air fryers can be set to specific temperatures and times with some precision, which is ideal for curing polymer clay. However, some air fryers may not go low enough in temperature, and an oven thermometer should be used to ensure the correct temperature is reached. Polymer clay can be cured for longer than necessary without any negative consequences, so even if the temperature is not low enough, it will not ruin the clay as long as it does not burn.

The small "floor space" of air fryers could be an issue when curing larger pieces of clay. This can be mitigated by using racks or risers to create more area, as long as the heated air can still circulate around the clay.

It is important to note that lightweight clay pieces may blow around in the air fryer due to the strong fans. This can be prevented by creating a small wooden support with a hole in it and a cocoon of aluminium foil to hold the piece in place.

Overall, air fryers are a viable option for curing polymer clay, but there are some considerations to keep in mind, such as temperature control and managing lightweight pieces.

Use a standing oven thermometer to check the temperature

Using a standing oven thermometer is a great way to check the temperature when curing polymer clay in an air fryer. Here are some detailed instructions to ensure you're doing it correctly:

First, purchase an oven thermometer. You can find these at most grocery stores or anywhere kitchen supplies are sold. It's best to get an inexpensive one that can stand on its own. Some thermometers can also be hung, but for an air fryer, you'll want to place it right next to your clay.

Before using your thermometer, it's important to verify its accuracy. You can do this by testing it in boiling or ice water to ensure it provides accurate readings. Once you've calibrated your thermometer, be sure to read and follow the manufacturer's instructions for measuring air fryer temperatures.

When curing your polymer clay, place the thermometer right next to it. This will ensure you get an accurate reading of the temperature around your clay. Avoid placing the thermometer in the path of the air fryer's fan, as this can affect the reading.

Keep in mind that different types of food require different temperatures for cooking. For example, most egg dishes cook best at a lower temperature range of 275°F to 350°F, while meats usually require higher heat, around 390°F to 400°F. Adjust the air fryer's temperature according to the type of clay you're curing.

By following these steps, you can be confident that you're curing your polymer clay at the correct temperature. Remember, temperature control is crucial in the curing process, and using a standing oven thermometer will help you achieve the desired results.

Lightweight clay pieces may blow around in an air fryer

When using an air fryer to cure polymer clay, it is important to be cautious of lightweight clay pieces. The fans in air fryers blow heated air around the cavity, which can cause lightweight clay pieces to blow around. This can result in uneven curing or even damage to the pieces. To prevent this, it is recommended to use a small wooden support with a hole in it to hold the pieces in place. You can also create a cocoon with aluminium foil, tucking one end through the hole in the wood and winding it around to secure it. It is important to ensure that the foil is not tight around the piece, as its only purpose is to act as a windshield.

Additionally, air fryers have smaller cavities than toaster ovens, which can make it challenging to arrange the clay pieces without overcrowding. To maximize space, you can use racks or risers to create more area for the clay, ensuring that the heated air can still circulate around the pieces.

Furthermore, air fryers have stronger fans than regular convection ovens, which can cause the lightweight clay pieces to be more susceptible to the force of the blowing air. This may result in the pieces moving around or even blowing out of the air fryer if not secured properly. Therefore, it is crucial to use a secure holding mechanism and place the air fryer in an area where it cannot be knocked over or disturbed.

Another factor to consider is the temperature setting. Air fryers heat up quickly and can reach temperatures up to 230°C (445°F). Starting the curing process at a lower temperature than usual can help prevent the clay pieces from blowing around due to the intense heat. It is recommended to use an oven thermometer to ensure that the air fryer is achieving the correct temperature for curing polymer clay.

In conclusion, while air fryers can be used to cure polymer clay, special consideration must be given to lightweight clay pieces to prevent them from blowing around. By using secure holding mechanisms, maximizing space with racks or risers, and being cautious of the temperature settings, you can successfully cure lightweight polymer clay pieces in an air fryer without them blowing around.

Air fryers have smaller cavities than convection ovens

Air fryers are much smaller than convection ovens. The standard size for most convection ovens is about 30 inches wide, 36 inches tall, and 25–27 inches deep, while air fryers are countertop appliances. This smaller cavity size in air fryers means they can't cook as much food at once as a convection oven. Convection ovens allow you to cook significantly more, making them ideal for cooking for a larger group of people.

The smaller size of air fryers also means they preheat faster than convection ovens. The countertop size of air fryers also positions the food closer to the heating elements, which encourages food to cook quicker.

The "floor space" in air fryers is smaller than in even toaster ovens, which could be an issue when curing polymer clay. You can use racks or risers to create more area for the clay, as long as the heated air can still circulate around most parts of the clay.

While both air fryers and convection ovens use fans to circulate hot air, they have different heating methods and capacities. Air fryers typically cook from the top down and don't have a bottom heating element. Convection ovens, on the other hand, use the oven's main heating element, a fan, and sometimes a third heating element to distribute heat throughout the oven cavity.

Convection ovens are better suited for roasting and baking, while air fryers are ideal for creating a crunchy, crisp exterior that mimics fried foods.

Polymer clay emits a tiny amount of vaporized oil when heated

Air fryers circulate hot air to cook food that would otherwise be submerged in oil. They can be used to cure polymer clay, which is made from PVC (vinyl), plasticizer, pigments, fillers (like kaolin), and a touch of oils. Polymer clay gets slightly softer as it warms up but begins to solidify and harden when it reaches about 130°F (55°C).

Therefore, when using an air fryer to cure polymer clay, it is important to ensure that the temperature does not exceed the recommended range for curing polymer clay. Additionally, it is advisable to use a standing oven thermometer to monitor the temperature accurately, as temperature settings on appliances can sometimes be inaccurate. By following these precautions, you can safely use an air fryer to cure polymer clay while minimizing the release of vaporized oil.
