Can polymer clay handle fire?

Polymer clay is a versatile and popular crafting material known for its ability to be molded, sculpted, and baked to create a wide range of projects. While polymer clay is designed to be cured or “baked” at relatively low temperatures, it is not suitable for handling direct flames or intense heat sources. In this article, we’ll explore the relationship between polymer clay and fire, and the precautions to take when working with this material.

Understanding Polymer Clay

Polymer clay is composed of a blend of polymer particles, plasticizers, pigments, and additives. When polymer clay is baked in a regular home oven, the heat causes a chemical reaction that transforms the soft clay into a hard and durable material. The recommended baking temperatures for polymer clay typically range from 215°F to 275°F (100°C to 135°C).

Limitations with Fire

Polymer clay is not designed to handle direct exposure to open flames, such as a lighter or torch flame. Subjecting polymer clay to high temperatures from an open flame can have several negative effects:

  • Combustion: Polymer clay is not flame-resistant and may combust or catch fire if exposed to direct flames or intense heat sources.
  • Release of Harmful Fumes: When polymer clay burns, it can release harmful fumes and smoke, including potentially toxic gases.
  • Damage to Project: Direct exposure to fire can cause polymer clay to melt, warp, or lose its shape, resulting in damage to your project.

Safety Precautions

When working with polymer clay, it’s important to follow safety precautions to avoid any risks associated with fire:

  • Use an Oven: Always bake polymer clay projects in a regular home oven at the recommended temperatures specified by the manufacturer. Avoid using open flames or torches.
  • Protect Your Workspace: When baking polymer clay, use a baking sheet or ceramic tile to protect your oven and workspace from direct contact with the clay.
  • Adequate Ventilation: Ensure that your workspace is well-ventilated when baking polymer clay to allow any fumes to dissipate safely.
  • Avoid High Heat: Keep polymer clay away from open flames, stovetops, hot surfaces, and other sources of high heat to prevent damage or combustion.


In conclusion, polymer clay is not designed to handle fire or direct exposure to flames. While polymer clay is safe to bake in a regular home oven at recommended temperatures, subjecting it to open flames or intense heat sources can result in combustion, harmful fumes, and damage to your project. It’s important to follow proper safety precautions and use polymer clay as intended to ensure your safety and the successful completion of your creative projects.
