Cultural Heritage & Archaeometry

Cultural objects-paintings, ceramics, metals, manuscripts, stone, wood-carry layered evidence about materials, craft, use, and time. This page turns that evidence into insight through non-destructive and minimally invasive instrumental analysis, translating specialist data into decisions that curators, conservators, and researchers can act on.

What you'll find here

Clear method primers that map techniques to questions collections teams actually ask.
Case-style vignettes that show how multi-tech workflows answer authenticity, provenance, condition, and treatment planning.
Reusable workflows & checklists for field, lab, and loan-prep contexts.
Collaboration routes for museums, archives, and universities to co-develop protocols and share data.

Techniques at a glance

XRF / μ-XRF

Best for: metals, ceramics, wall paintings, inks (elemental level).
Answers: alloying and pigment composition, layer discrimination, corrosion mapping.
Outputs: spot spectra; 2D elemental maps that overlay on object photos.

Raman spectroscopy

Best for: pigments, minerals, varnishes, organic residues.
Answers: crystalline phases, look-alike pigments, restoration materials.
Outputs: fingerprint spectra; phase distribution plots.

FT-IR (incl. micro-ATR)

Best for: binders, varnishes, paper fibers, adhesives.
Answers: functional groups, oxidation/aging markers, coating identification.
Outputs: absorbance spectra; library matches and abundance estimates.

SEM-EDS (microscale)

Best for: corrosion layers, paint cross-sections, ceramic tempers.
Answers: microstructure, point/line/area elemental analysis, interface chemistry.
Outputs: high-resolution images plus elemental overlays.

X-ray imaging (radiography / CT / micro-CT)

Best for: wooden cores, joins, armatures, internal repairs, stratigraphy.
Answers: hidden construction, voids and fractures, fasteners and past interventions.
Outputs: radiographs; volumetric slices and reconstructions.

How to choose: start from the question (authenticity, provenance, condition, treatment) and material class, then combine elemental + molecular + structural methods for converging evidence.

Case vignettes (illustrative patterns)

Black-figure ceramics - μ-XRF maps distinguish clay body vs. slip chemistry and kiln batches, informing provenance hypotheses and display groupings.
Blue on murals - Raman separates lapis lazuli from azurite and Prussian blue, guiding compatible in-painting materials.
Bronze with active corrosion - SEM-EDS reveals tin depletion and chloride networks; mitigation targets shift from surface cleaning to stabilization.
Paper with glossy coating - FT-IR confirms aged natural resin; solvent tests and controlled humidity are prioritized over mechanical thinning.
Polychrome woodwork - X-ray/CT exposes internal dowels and historical repairs; consolidation restricts to load-bearing zones only.
Overpaint on canvas - Multispectral imaging plus Raman isolates later interventions; treatment plan preserves historically significant retouches while reducing visually discordant ones.

Each vignette documents: Question → Methods used → Key findings → Data snapshots (spectrum/maps/slices) → Practical recommendation.

Methods 101 (five-minute starters)

Question-first design: define what must be answered, then pick techniques; don't let tool availability drive the question.
Non-destructive by default: escalate to micro-sampling only when decision-critical, and record location/size with images and coordinates.
Converging lines of evidence: pair elemental (XRF) with molecular (Raman/FT-IR) and structural (X-ray/CT) to avoid single-method bias.
Quality assurance: blanks, certified references, repeatability checks; capture geometry, dwell times, calibration, and environment in metadata.
Readable deliverables: translate spectra and tomograms into short, decision-ready briefs with annotated overlays and uncertainty notes.

Data & workflow essentials

Acquisition templates: filenames and IDs (ObjectID_Method_Mode_Date_SpotID); coordinate systems for maps and slices; color-managed overlays.
Minimal metadata set: instrument model/serial, geometry, calibration, integration time, environmental conditions, operator, versioned SOP link.
Visualization: align elemental or phase maps with orthophotos; provide dynamic range notes so others can reproduce contrast and thresholds.
Citation & reuse: when sharing beyond internal reports, include method limits, detection thresholds, and any assumptions used in interpretation.

Collaboration & contributions

We welcome museum partners, conservation studios, and academic labs to:

Co-author vignette case notes and make anonymized datasets discoverable.
Compare protocols across instruments or vendors to strengthen interoperability.
Develop short courses and lab visits for curators, registrars, and early-career conservators.

Use the contact form to outline your collection context, materials, driving questions, constraints, and timelines; we'll propose a right-sized method mix and milestones.

Cultural context & recommended reading

Scientific analysis does not live in a vacuum: heritage is framed by how societies tell stories, with presence and absence both shaping meaning. For a broader cultural lens, see reflections on off-screen patience in cinema and discussions of narratives of war and memory-useful reminders that interpretation, context, and ethics are inseparable from materials and methods.
