Porcelain sculptures are delicate artworks that require careful storage to maintain their beauty and structural integrity over time. To ensure long-term preservation, follow these best practices:

1. Control Humidity and Temperature: Store porcelain in a stable environment with 40-60% relative humidity and a temperature between 60-75°F (15-24°C). Avoid extreme fluctuations, as they can cause cracking or glaze damage.

2. Use Acid-Free Materials: Wrap sculptures in acid-free tissue paper or soft cotton cloth to prevent surface scratches. Avoid plastic wraps, which can trap moisture and promote mold growth.

3. Proper Positioning: Store sculptures upright or in their original orientation to prevent stress on weak points. Use padded supports for fragile parts like extended limbs or thin edges.

4. Avoid Direct Light and Dust: Keep porcelain away from sunlight, which can fade colors, and store it in a dust-free cabinet or display case with UV-protective glass.

5. Regular Inspection: Check stored pieces every few months for signs of deterioration, such as discoloration or cracks, and adjust storage conditions as needed.

By following these guidelines, collectors can protect their porcelain sculptures from deterioration and enjoy their timeless beauty for generations.
