How Do You Store Polymer Clay to Keep It Fresh and Usable?
Polymer clay is a versatile and beloved medium for artists, crafters, and hobbyists alike. Its vibrant colors, pliability, and ability to harden permanently when baked make it a favorite for creating everything from intricate jewelry to whimsical figurines. However, one common question that arises among both beginners and seasoned creators is: How do you store polymer clay to keep it fresh, workable, and ready for your next project?
Proper storage of polymer clay is essential not only to maintain its texture and prevent it from drying out or becoming brittle but also to preserve the colors and ensure it remains free from dust and debris. Without the right storage techniques, clay can become unusable, leading to frustration and wasted materials. Understanding the basics of storage will empower you to extend the life of your clay and keep your creative process smooth and enjoyable.
In the following sections, we’ll explore the best practices for storing polymer clay, including ideal containers, environmental conditions, and tips to avoid common pitfalls. Whether you’re working with small amounts or large collections, mastering storage will help you get the most out of your polymer clay and keep your artistic journey thriving.
Best Practices for Storing Polymer Clay
Proper storage of polymer clay is essential to maintain its pliability and prevent contamination. Polymer clay should be kept in a cool, dry environment away from direct sunlight, which can cause premature curing or discoloration. Avoid storing clay near heat sources or in areas with significant temperature fluctuations, as this can affect the clay’s consistency.
To preserve the clay’s integrity, it is important to prevent dust, lint, or other particles from settling on the surface. Using airtight containers or resealable plastic bags can effectively protect the clay from environmental contaminants and help maintain moisture levels. If you work with multiple colors, store each color separately to avoid unwanted mixing or staining.
Recommended Storage Materials
Choosing the appropriate storage container is critical for polymer clay longevity. The following materials are commonly used and effective for storing polymer clay:
- Plastic Containers: Clear plastic containers with tight-fitting lids provide an airtight environment, allowing you to easily view the colors without opening the container.
- Resealable Plastic Bags: Ziplock or similar bags are convenient and flexible for storing smaller amounts of clay or individual blocks.
- Wax Paper or Parchment Paper: Wrapping clay in wax or parchment paper before placing it in a container prevents it from sticking and makes handling easier.
- Glass Jars: For long-term storage, glass jars with sealed lids prevent exposure to air and contaminants, although they require wrapping to avoid sticking.
Temperature and Humidity Considerations
Polymer clay is sensitive to temperature and humidity, which can influence its texture and workability. Ideal storage conditions include:
- Temperature: Between 65°F and 75°F (18°C to 24°C) is optimal. Avoid freezing temperatures, which can make the clay brittle, and excessive heat, which can cause premature curing.
- Humidity: Moderate humidity levels are preferable. Excessive moisture can lead to a sticky surface, while very dry conditions may harden the clay.
Using climate-controlled storage areas, such as a dedicated drawer or cabinet, helps maintain these conditions consistently.
Comparison of Storage Options
| Storage Method | Advantages | Disadvantages | Best Use |
|---|---|---|---|
| Plastic Containers | Durable, airtight, visible | Can trap moisture if sealed wet clay | Storing multiple colors or large quantities |
| Resealable Plastic Bags | Flexible, space-saving, inexpensive | Can tear, less durable | Small amounts or travel storage |
| Wax/Parchment Paper Wrapping | Prevents sticking, easy to use | Needs secondary container for protection | Separating individual blocks or colors |
| Glass Jars | Airtight, non-reactive, aesthetic | Fragile, heavier, requires wrapping | Long-term storage of premium clay |
Tips for Long-Term Storage
When storing polymer clay for extended periods, several additional steps can help maintain quality:
- Condition Before Storing: Ensure the clay is properly conditioned to a uniform texture before storage to avoid hard spots.
- Label Containers: Use labels with the clay type, color, and date of purchase to keep track of inventory and freshness.
- Avoid Excessive Compression: Store clay loosely to prevent deformation; avoid stacking heavy objects on top.
- Regular Checks: Periodically inspect stored clay for changes in texture, color, or signs of drying out, and recondition if necessary.
Adhering to these storage practices extends the usability and performance of polymer clay, ensuring it remains ready for your creative projects.
Proper Techniques for Storing Polymer Clay
Storing polymer clay correctly is essential to maintain its pliability and usability over time. Improper storage can lead to drying, dust contamination, or unwanted hardening. The key factors to consider are protection from air, moisture control, and temperature regulation.
The following guidelines will help preserve the quality of polymer clay:
- Keep clay airtight: Polymer clay hardens only when baked, but exposure to air can cause it to become dry and crumbly. Use airtight containers or sealed plastic bags to limit air exposure.
- Store at room temperature: Avoid extreme temperatures. Polymer clay should be stored in a cool, dry place, ideally between 65°F and 75°F (18°C to 24°C). Excessive heat can cause premature curing, while cold temperatures can make the clay brittle.
- Separate colors: To prevent color contamination, store different colors separately. Use individual ziplock bags or small containers for each color.
- Use moisture-resistant packaging: While polymer clay does not dry out like natural clays, it can attract dust and debris. Wrapping it in plastic wrap before placing it in a container adds an extra layer of protection.
- Avoid direct sunlight: Prolonged exposure to sunlight can alter the clay’s color or texture.
Recommended Storage Materials for Polymer Clay
Choosing the right storage materials enhances the longevity and ease of use for polymer clay. The materials should be non-reactive and provide a secure environment.
| Material | Advantages | Disadvantages | Recommended Uses |
|---|---|---|---|
| Plastic Ziplock Bags | Inexpensive, airtight, easy to label, lightweight | Can tear, not rigid, may allow slight air exchange over time | Storing small amounts or individual colors |
| Airtight Plastic Containers | Durable, reusable, protects from crushing, good sealing | Bulkier, more expensive, requires cleaning | Storing larger quantities or mixed color batches |
| Glass Jars with Sealed Lids | Non-porous, airtight, easy to clean, prevents contamination | Fragile, heavier, more costly | Long-term storage, display of unused clay blocks |
| Plastic Wrap or Cling Film | Provides an extra layer of protection, inexpensive | Not a standalone solution, can stick to clay surface | Wrapping clay before placing in bags or containers |
Storage Environment Considerations
Maintaining an appropriate environment is crucial to prevent degradation of polymer clay.
- Humidity control: Although polymer clay does not absorb moisture like natural clay, excessive humidity can encourage mold growth on storage materials or labels. Use silica gel packets in storage containers if necessary.
- Dust and debris protection: Keep storage containers clean and avoid storing clay near open windows or dusty workspaces.
- Organized storage system: Label containers with the clay color and purchase date to monitor freshness and inventory easily.
- Keep away from solvents: Avoid storing polymer clay near chemicals or solvents that could react adversely with the clay surface.
Tips for Long-Term Polymer Clay Storage
For artists and crafters who accumulate polymer clay over time, certain practices help ensure the clay remains workable even after extended periods.
- Check the clay periodically for texture changes or contamination.
- Re-condition older clay by kneading it thoroughly before use; warming slightly with hands can improve pliability.
- Store clay in a dedicated craft drawer or box, avoiding areas where heavy objects could crush the blocks.
- Use archival-quality containers if storing clay for multiple years to minimize chemical degradation.
Expert Recommendations on How Do You Store Polymer Clay
Linda Martinez (Professional Polymer Clay Artist and Instructor). Proper storage of polymer clay is essential to maintain its pliability and prevent contamination. I recommend keeping unused clay in airtight containers or resealable plastic bags, away from direct sunlight and extreme temperatures.
