AI Hidden Ceramic Restoration Detection for Antique Dealers

01

Why it matters

Without it, misattributed pieces, undisclosed restorations, unvetted valuations, and potential ethical or legal breaches in provenance and CITES compliance can occur, complicating sales, insurance, and conservation planning.

From design to safety

1. Design

   AI previews restoration risk profile

   The AI reads catalog data, high-resolution images, UV results, and historical records to pre-screen pieces for restoration risk and disclosure requirements; it maps risk to database fields and creates a restoration plan outline for the client ledger.

   • hairline cracks inspection
   • UV inspection lamp
   • disclosure ledger

2. Build

   AI flags concealment indicators

   During sourcing and authentication, the system analyzes surface photos, infrared or UV data, and provenance notes to flag concealed interventions and verify period coherence; it records timestamped image sets and stores provenance flags in the item dossier.

   • hairline cracks detection
   • restoration history file
   • overpaint analysis

3. Operation

   Ongoing integrity monitoring

   In the showroom and gallery, AI runs continuous checks on new arrivals, compares against previous condition reports, and prompts updates to condition and provenance notes; it generates periodic alerts for audience-facing disclosures and insurance listings.

   • UV inspection results
   • condition report database
   • provenance records

4. Maintenance

   Maintenance of evidence trails

   The system schedules periodic re-inspection using UV and magnification, records any new findings, and updates the disclosure status for each item; it maintains an auditable trail with certified time stamps and operator initials.

5. Safety

   Safety and compliance controls

   Qualified staff review detected restorations, ensure ethical disclosure, and sign off on consignments, insurance, and vetting documentation aligning with conservation standards; it enforces regulatory review and professional vetting before movement.

Part by part

1. 1

   UV inspection lamp

   Watch for

   UV findings indicating overpaint, varnish layering, or hidden repairs that differ from original glaze.

   AI action

   Flag pigment/varnish anomalies; trigger overpaint suspicion report.

2. 2

   hairline crack inspection device

   Watch for

   Unseen microcracks under varying light; potential structural weakness or fake aging patterns.

   AI action

   Highlight crack patterns and map severity.

3. 3

   restoration history file

   Watch for

   Incomplete or undocumented past repairs; gaps in conservation records.

   AI action

   Generate missing item in provenance dossier; request prior documentation.

4. 4

   overpaint analysis tool

   Watch for

   Discrepancies between known glaze and current surface color indicating retouching.

   AI action

   Produce overpaint suspicion alert and suggested restoration notes.

5. 5

   disclosure ledger

   Watch for

   Failure to disclose repairs or substitutions during sale; misrepresentation risk.

   AI action

   Produce disclosure status and required museum-grade notes.

6. 6

   magnification loupe with digital capture

   Watch for

   Subtle restorations visible only at high magnification; aids in verification.

   AI action

   Record magnified evidence and feed into condition history.

How to roll it out

1. Phase 1

   Phase 1

   Baseline data capture, install UV lamp, and link to existing provenance and condition databases.

2. Phase 2

   Phase 2

   Add restoration history integration, image capture routines, and AI-driven flagging in the warehouse workflow.

3. Phase 3

   Phase 3

   Deploy in showroom vetting, ties into valuations, insurance, and vetting documentation across auctions.

06

Where people stay in charge

• All restoration flags require verification by a qualified conservator-restorer before any sale or disclosure is updated.
• Disclosures must be signed off by the valuer or accredited conservator before consignments leave the studio.
• Vulnerable or legally restricted items must be escalated to the regulatory body or professional vetting committee for approval.
