Documenting the provenance of contemporary porcelain sculptures is essential for establishing authenticity, value, and historical significance. Here are the most effective methods to ensure accurate and reliable provenance records:

1. Artist Certificates and Signatures: Always obtain a signed certificate of authenticity from the artist, including details like creation date, materials, and edition number (if applicable). Hand-signed pieces add an extra layer of credibility.

2. Digital Certificates and Blockchain: Leverage blockchain technology to create tamper-proof digital certificates. Platforms like Verisart or Artory provide secure, immutable records of ownership and transaction history.

3. Photographic Documentation: High-resolution images of the sculpture from multiple angles, including close-ups of unique markings or signatures, serve as visual proof of condition and originality.

4. Exhibition and Publication Records: Track the sculpture’s inclusion in galleries, museums, or art books. Curatorial notes and exhibition catalogs can validate its provenance.

5. Provenance Chain Documentation: Maintain a detailed ownership history, including invoices, receipts, and transfer agreements. Each transaction should be recorded with dates and parties involved.

By combining traditional methods with modern digital solutions, collectors and artists can safeguard the legacy of porcelain sculptures, ensuring their authenticity for future generations.
