To properly store synthetic clay, ensure it is cool, clean, and dry, then seal it individually in airtight containers, ideally separating colors.
Storing synthetic clay correctly is essential to maintain its workability, freshness, and prevent unwanted issues like hardening, contamination, or color mixing. The key is to protect the clay from air, moisture, heat, and contact with other substances.
Preparing Synthetic Clay for Storage
Before storing, proper preparation is crucial:
- Ensure it's Cool: Store clay at room temperature or cooler. Avoid hot environments like direct sunlight or vehicles, which can start the curing process prematurely.
- Ensure it's Clean: Remove any lint, dust, or debris from the clay surface. Working on a clean surface helps prevent incorporating contaminants.
- Ensure it's Dry: While synthetic clay doesn't contain water, ensure the surface is dry and not exposed to excess humidity during storage preparation.
This preparation step helps maintain the clay's texture and prevents issues over time.
Sealing and Packaging
The most important step is sealing the clay to create an airtight barrier.
- Use Airtight Containers: Sealing each block or piece of clay in an airtight container is recommended. This could include:
- Polypropylene (PP) plastic containers
- Polyethylene (PE) plastic bags (like resealable freezer bags)
- Glass jars with airtight lids
- Individual Sealing: Seal each block or distinct piece of clay separately. This preserves its freshness and prevents contamination from other materials or colors.
This sealing method aligns directly with the guidance that sealing each block or piece of clay in an airtight container can preserve its freshness and prevent contamination.
Preventing Color Bleeding
If you have multiple colors, it's vital to keep them separate.
- Separate by Color: Store different colors in their own individual airtight containers or bags. This is advisable to prevent colours from bleeding into each other over time, especially with softer clays or in warmer conditions.
Summary of Best Practices
For effective synthetic clay storage, follow these steps based on best practices:
- Start with clay that is cool, clean, and dry.
- Seal each block or piece of clay individually.
- Use airtight containers or bags made from compatible plastics (avoid materials like PVC, which can react with some clay plasticizers).
- Separate different colors to prevent bleeding.
- Store the sealed clay in a cool, dark place away from direct heat or sunlight.
By following these steps, you can significantly extend the shelf life and maintain the quality of your synthetic clay.
