Restoring antique porcelain sculptures is a delicate and meticulous process that requires careful documentation to preserve their historical and artistic value. Here are the best methods for documenting the restoration process effectively:

1. High-Resolution Photography: Capture detailed before-and-after images from multiple angles to record the sculpture’s condition. Use consistent lighting and a neutral background for accuracy.

2. Written Logs: Maintain a step-by-step written record of each restoration phase, including materials used, techniques applied, and challenges encountered. This log serves as a reference for future conservation efforts.

3. Digital 3D Scanning: Employ 3D scanning technology to create a digital replica of the sculpture. This allows for precise measurements and virtual analysis of damage and repairs.

4. Material Testing Reports: Document any scientific tests performed, such as pigment analysis or glaze composition, to ensure authenticity and guide restoration decisions.

5. Video Documentation: Record the restoration process in real-time to provide a visual narrative of the techniques used, which can be invaluable for educational or archival purposes.

By combining these methods, restorers can create a comprehensive and transparent record of the restoration process, ensuring the longevity and integrity of antique porcelain sculptures for future generations.
