What are the cons of using polymer clay?

Polymer clay is a versatile and popular medium used by artists and crafters for a wide range of creative projects. It offers numerous benefits, such as ease of use, vibrant colors, and the ability to hold intricate details. However, like any material, polymer clay also has its downsides. In this article, we’ll explore some of the cons or disadvantages of using polymer clay to help you make informed decisions about your crafting endeavors.

1. Brittleness and Breakage

One of the notable cons of polymer clay is its susceptibility to brittleness and breakage, especially in thin or delicate areas. Polymer clay can become fragile over time, and excessive bending or stress can cause it to crack or break. While conditioning and proper handling can reduce this risk, extra care is required when working with intricate or thin pieces.

2. Baking Challenges

Proper baking is crucial for polymer clay projects. If not baked at the correct temperature or for the right duration, polymer clay can become too brittle or develop surface issues. Overbaking can result in a burnt or discolored appearance, while underbaking can leave the clay soft and susceptible to damage.

3. Color Fading

Exposure to sunlight and UV rays over time can lead to color fading in polymer clay creations. While some brands offer UV-resistant formulas, it’s still important to consider the longevity of your projects, especially if they will be displayed in well-lit areas or near windows.

4. Limited Heat Resistance

Polymer clay has limited heat resistance compared to other materials. It can soften or deform if exposed to high temperatures, such as being left in a hot car or near a heat source. This can affect the durability and shape of your creations if they are not stored or displayed properly.

5. Chemical Sensitivity

Some individuals may experience skin sensitivity or allergies when handling certain brands or types of polymer clay. It’s important to read product labels, wear protective gloves if needed, and work in a well-ventilated area to minimize potential health risks.

6. Not Food-Safe

Polymer clay is not considered food-safe and should not come into direct contact with food or beverages. It’s important to avoid using polymer clay for items like food containers, utensils, or drinkware.

7. Environmental Concerns

Polymer clay is made from synthetic materials, which raises environmental concerns. The production and disposal of polymer clay may contribute to plastic waste and environmental impact. Artists and crafters should be mindful of their consumption and consider eco-friendly alternatives when possible.


While polymer clay offers many creative possibilities and advantages, it’s important to be aware of its potential drawbacks. Understanding the cons of using polymer clay can help you make informed choices and take appropriate precautions when working with this versatile medium. By following best practices, proper techniques, and safety guidelines, you can mitigate many of the disadvantages associated with polymer clay and create beautiful and lasting artworks.
