What You'll Learn
Acrylic paints should be oven-safe
Polymer clay is a fun and versatile material to work with. It stays soft and pliable and only dries out or hardens when you bake it in an oven. When it comes to painting polymer clay creations, artists often use acrylic paints. But can you put painted polymer clay in the oven?
When baking painted polymer clay, it's important to follow the clay manufacturer's instructions for baking temperature and time. In most cases, polymer clay bakes at around 275 degrees Fahrenheit (135 degrees Celsius) for 15 to 30 minutes per 1/4 inch (0.64 cm) of clay thickness. However, always refer to the package instructions as the temperature and time may vary depending on the type of clay.
It's also crucial to preheat your oven properly. Use an oven thermometer to ensure that your oven is at the correct temperature, as some ovens may have inaccurate temperature recordings. Additionally, cover the clay with a tented piece of aluminum foil or an upside-down baking pan to prevent burning.
Once the clay is done baking, remove it from the oven with oven mitts and place it on a heat-safe surface to cool completely. This may take between 30 to 60 minutes.
By following these instructions, you can safely bake your painted polymer clay creations and ensure that your acrylic paint does not bubble or crack.

Use a separate oven thermometer to gauge the temperature
When baking polymer clay, it is essential to ensure that your oven is at the right temperature. Oven thermometers are a great way to test your oven's temperature accuracy and ensure your creations turn out as expected. Polymer clay is sensitive to temperature, and if overcooked, it can burn, brown, yellow, or undergo unwanted surface changes. Similarly, if the temperature is too low, the plasticizers won't polymerize sufficiently, causing the piece to crumble and become brittle over time.
To choose an oven thermometer, opt for one that is easy to read and place inside your oven. Accuracy, legibility, stability, and ease of use are critical factors in selecting the right thermometer. You can choose between a digital probe thermometer and a standard round metal one. Digital thermometers, such as the Polder All in One Digital Oven Thermometer/Timer, offer features such as a shelf clip, magnetic wall mounts, and an alarm when the oven reaches the desired temperature. Standard round metal thermometers are less expensive but may be less accurate, so you might need to use two and determine the true temperature by averaging their readings.
Before baking your polymer clay, it is recommended to run a pre-baking test to calibrate your oven's temperature. To do this, pinch off a small piece of clay and form a disc about 1/4 inch thick and 1/2 inch in diameter. Bake this test piece according to the manufacturer's instructions, then remove it from the oven and check the color. If you notice any darkened areas, your oven is too hot. In this case, lower the temperature by about 10 degrees Fahrenheit and repeat the test.
By using a separate oven thermometer and conducting a pre-baking test, you can ensure that your oven is at the correct temperature for curing your polymer clay creations. This will help you avoid underbaking or scorching your artwork and achieve the desired results.

Avoid using a metal or glass surface
When baking polymer clay, it is important to avoid placing your clay on a metal or glass surface. Polymer clay should be baked at a consistent temperature to avoid over-baking or burning. Metal and glass surfaces can cause uneven heating, leading to potential issues with your creation.
To ensure even heating, it is recommended to use a wooden board, a ceramic plate, or tiles. These materials are better at maintaining a steady temperature and will help you achieve the desired results without risking damage to your clay creation.
Additionally, when baking polymer clay, it is crucial to preheat your oven to the appropriate temperature. The ideal temperature for baking polymer clay is typically around 275°F (135°C) for 15 to 30 minutes per 1/4 inch of clay thickness. However, always refer to the specific instructions provided with your clay.
After baking, remove your clay creation from the oven using oven mitts and place it on a heat-safe surface to cool. This cooling process can take between 30 to 60 minutes. It is important to note that you should avoid breathing in any fumes released during the baking process.
While it is generally recommended to bake polymer clay before painting, some sources suggest that acrylic paints can withstand the oven temperatures required for baking polymer clay. However, it is crucial to monitor the temperature to ensure it doesn't get too high, as instant glues, for example, will weaken in high heat.

Place a couple of ceramic tiles inside the oven to stabilise temperature
When baking polymer clay, it is important to ensure that the oven temperature is stable and even. One way to achieve this is by placing a couple of ceramic tiles inside the oven. The ceramic tiles act as a heat sink, helping to stabilise the temperature and distribute heat evenly. This is especially useful if you are using a toaster oven, as they tend to have fluctuations in temperature.
To use this method, place the ceramic tiles in the bottom of an aluminium pan and cover them with parchment paper. This prevents any glaze on the tile from sticking to your clay. Then, place your clay creation on top of the paper and cover it with another aluminium pan. This setup ensures even heating and protects your clay from scorching.
It is important to note that the oven temperature and baking time depend on the type and thickness of the clay you are using. Always refer to the package instructions for the recommended temperature and baking duration. As a general rule, aim for 30 to 45 minutes per 1/4 inch (0.64 cm) of clay thickness.
Regarding the paint, Acrylic paints should be able to withstand the oven temperatures for polymer clay. However, it is recommended to monitor the temperature to ensure it doesn't get too high, as instant glues will weaken in the heat. Additionally, consider using thickened liquid polymer clays or regular liquid clay for attaching baked polymer clay pieces, as they provide strong adhesion.
