Is Polymer Clay Flammable? Stay Safe with This Essential Guide


Understanding Polymer Clay

Polymer clay is a type of modeling clay made from polyvinyl chloride (PVC), plasticizers, and colorants. It has become increasingly popular among artists and crafters due to its versatility and ability to be cured in a home oven. Polymer clay comes in various colors and is used to create sculptures, jewelry, and decorative items.

Flammability of Polymer Clay

Polymer clay is not highly flammable, but it can be combustible under certain conditions. The clay itself does not catch fire easily and will not burn like paper or wood. However, it is important to note that polymer clay contains plasticizers and other chemicals that can release toxic fumes when exposed to high temperatures.

At high temperatures, polymer clay can emit harmful gases and smoke. Therefore, it is crucial to bake polymer clay in a well-ventilated area or use a dedicated oven for clay projects to avoid inhaling these fumes.

Safely Baking Polymer Clay

To safely bake polymer clay, follow these tips:

  • Preheat your oven according to the manufacturer’s instructions.
  • Place your clay creation on a baking sheet lined with parchment paper or a silicone mat.
  • Avoid using metal baking pans or surfaces, as they can transfer heat unevenly and potentially damage the clay.
  • Set the baking time and temperature as per the instructions provided with your clay. It is important not to exceed the recommended temperature as it may cause the clay to burn or emit toxic fumes.
  • Always keep an eye on your clay while it’s baking, and do not leave the oven unattended.
  • Allow the clay to cool completely before handling or painting it.

Additional Safety Measures

While working with polymer clay, it is crucial to take some additional safety measures to prevent any accidents or health risks:

  • Avoid inhaling clay dust by wearing a dust mask or working in a well-ventilated area.
  • Handle clay with clean hands and work surfaces to avoid contamination or mixing with other materials.
  • Keep clay away from open flames, heat sources, and electrical appliances to minimize the risk of fire.
  • Store polymer clay in a cool and dry place, away from direct sunlight and extreme temperatures.
  • Always wash your hands thoroughly after handling polymer clay.

By following these safety measures, you can enjoy working with polymer clay while minimizing any potential risks.
