Storing unfired porcelain sculptures requires careful attention to humidity levels to prevent damage and ensure structural integrity. The ideal humidity range typically falls between 40% and 60%, as excessive moisture can cause warping or mold growth, while low humidity may lead to cracking.

Several key factors influence the optimal storage conditions:

1. Material Sensitivity – Unfired porcelain is highly porous, making it vulnerable to rapid moisture absorption or evaporation.

2. Climate Variations – Seasonal changes and local weather conditions must be accounted for in storage environments.

3. Storage Duration – Long-term storage demands stricter humidity control compared to short-term solutions.

4. Ventilation – Proper airflow prevents condensation while maintaining stable moisture levels.

5. Monitoring Tools – Hygrometers help track humidity, ensuring adjustments can be made promptly.

By balancing these factors, artists and collectors can preserve unfired porcelain sculptures in optimal conditions, preventing irreversible damage and maintaining their artistic quality.
