Can you drink out of polymer clay cups?

Polymer clay is a versatile and popular medium used for creating a wide range of artistic and functional items. While it’s commonly used for crafting jewelry, sculptures, and decorative pieces, some artists and crafters may wonder whether polymer clay can be used to make drinkware, such as cups and mugs. In this article, we will delve into the topic of using polymer clay for drinkware and explore its safety and practicality.

The Nature of Polymer Clay

Polymer clay is a synthetic modeling material that consists of a polymer base mixed with coloring agents and additives. It becomes solid and durable when baked at the appropriate temperature. Polymer clay is not porous like natural clay, which means it doesn’t absorb liquids or moisture. This characteristic has led some people to consider using polymer clay for functional items, such as cups.

Safety Considerations

While polymer clay is generally safe for crafting purposes, there are important factors to consider when using it for drinkware:

  • Not Certified for Food Contact: Polymer clay is not specifically certified for food contact or drinkware use by regulatory agencies. As a result, there may be concerns about its long-term safety when in contact with beverages.
  • Temperature Sensitivity: Polymer clay may be sensitive to temperature changes, and extreme heat or cold could potentially affect its structure and stability over time.
  • Surface Coating: To make polymer clay cups more suitable for drinkware, artists may use sealants, glazes, or coatings to create a protective barrier. It’s crucial to ensure that any coatings used are safe for food contact and do not contain harmful chemicals.

Alternative Approaches

If you’re interested in creating drinkware with artistic designs similar to those achievable with polymer clay, you may consider alternative approaches:

  • Ceramics: Traditional ceramics, such as porcelain and stoneware, are commonly used for creating functional and food-safe drinkware. These materials are fired at high temperatures to achieve the necessary durability and safety.
  • Custom Designs: Collaborate with ceramic artists who can translate your polymer clay designs into safe and functional ceramic pieces.
  • Decorative Elements: Instead of using polymer clay for the entire cup, consider incorporating polymer clay decorations onto existing food-safe drinkware.


In conclusion, while polymer clay offers unique creative possibilities, using it for drinkware raises safety concerns and may not be the best option for functional items that come into direct contact with beverages. For artistic and decorative purposes, polymer clay can be a fantastic medium, but when it comes to creating safe and usable drinkware, it’s recommended to explore alternative materials and approaches that prioritize both aesthetics and safety.
