Why it matters
Without AI, corrosion assessment risks misreading haloing, mismanaging calcium phytate treatments, and missing escalation points, leading to irreversible damage and disputes over treatment records.
From design to safety
Design
AI-guided treatment planning
The system reads historical notes, imaging data, and proposed methods to generate a risk map and a treatment plan emphasizing reversibility, minimal intervention, and consistency with PACR accreditation while integrating condition-report templates and ethics reviews. It also encodes leaf-level provenance, binder information, and pigment indices, mapping to approved methods catalog and cross-checking with ethics review matrix.

Build
Equipment integration and calibration
Interfaces to imaging and chemical processing units are calibrated; calibration data, reference targets, and batch records establish trustworthy measurements, traceable provenance, and compliance with COSHH before on-lead benchwork begins; new SOPs are included. Calibration includes color checker passes, spectral response curves, and microdot references; operator validation is required before live leaf handling.

Operation
Ongoing condition monitoring
AI analyzes periodic scans and chemical readings, flags haloing progression, and updates treatment proposals with evidence-linked justifications; archiving includes condition report CR-L042-2026-11 with leaf-level metadata; cross-discipline notes sync. It cross-references leaf IDs, folio numbers, and ink batch IDs to avoid misassignment and maintains a complete imaging modality log.

Maintenance
Regular calibration and stock control
Routine checks of imaging sensitivity, bath concentration, and consumables ensure data integrity, reproducibility, and compliance with COSHH prescriptions; lot tracing and expiry logging are mandatory; quarterly audits of archives. Replacement parts procurement follows shelf-life alerts linked to supplier certifications and internal QMS.

Safety
Compliance and ethics enforcement
AI enforces COSHH limits, records PACR-compliant decisions, and signs off with the accredited conservator and client, with audit trails for insurance and curation; imaging data remain protected by access controls; ethical reviews are embedded. Safety workflows require supervised handling of inks, solvents, and powered equipment with incident reporting integration.

Worked example
Catching haloing drift before leaf separation
Illustrative scenario with sample data.
A manuscript leaf shows progressive haloing around iron gall ink; AI maps halos, suggests calcium phytate treatment plan, and schedules follow-up imaging.
Signal in
leafID: L-042, location: folio 3, inkType: iron gall, haloRadius: 1.8mm, bathConc: 12% w/v, temp: 22C, lastTreatment: 6 months ago, paperType: rag, binder: alum-rosin
System out
alert: Haloing progression detected on leaf L-042; recommended actions: perform microscopic imaging, initiate calcium phytate bath treatment with batch B-abs24, schedule follow-up imaging in 4 weeks; generate condition report CR-L042-2026-11; update risk map
Human sign-off: Head conservator approves treatment plan and signs off condition report; client notified; PACR file updated.
How to roll it out
Phase 1
Phase 1
Baseline data capture, calibrations, and approved treatment templates are established.
Phase 2
Phase 2
Pilot scans, bath trials, and reporting templates are validated against a small manuscript batch.
Phase 3
Phase 3
Full deployment with ongoing monitoring and integrated archiving into the condition reports system.
Where people stay in charge
- Only a qualified conservator or PACR-accredited conservator may authorize treatment plans and chemical handling procedures.
- AI-generated decisions must be reviewed against the studio’s treatment policy and ethical guidelines before execution.
- All client-facing reports must be signed by the accredited conservator and archived in the client file.
Questions owners and crews ask
What is AI used for in iron gall ink corrosion assessment?
AI analyzes imaging and chemical data to map corrosion, predict haloing, suggest calcium phytate treatments, and generate traceable condition reports for treatment proposals.
What data sources feed the AI system?
Imaging data, historical condition notes, bath concentrations, treatment batch records, and metadata from imaging sessions are ingested and correlated.
Who approves AI-generated treatment plans?
An accredited conservator or PACR-certified steward reviews and signs off before any treatment proceeds.
How is safety and ethics ensured in this workflow?
COSHH management, PACR-aligned records, and client notification are enforced; AI flags deviations for human review and archival integrity.
