Seeing Beneath the Paint: Imaging that Guides Restoration

Infrared Reflectography: Meeting the Artist’s First Draft

Infrared reflectography reveals carbon-based underdrawings, pentimenti, and compositional changes, often exposing the artist’s hand at its most spontaneous. Seeing these ghostly lines helps conservators respect intent while planning treatment. Tell us which discoveries surprised you most and why.

X-ray Radiography and CT: The Bones of a Painting

X-rays highlight dense materials like lead white, nails, and old tacks, mapping structural problems and earlier repairs. When needed, computed tomography renders panels in 3D, exposing worm tunnels and joins. Curious about a puzzling X-ray image? Ask and we’ll interpret it together.

UV Fluorescence and False-Color IR: Mapping Materials at a Glance

Ultraviolet fluorescence can make aged varnish glow green and overpaint shine dark, immediately locating later additions. False-color infrared distinguishes pigments by their spectral behavior. Want to learn how we decide where to clean first? Comment, and we’ll walk through a real example.

Chemistry of Cleaning: Varnishes, Solvents, and Gels

Conservators use Hansen and Hildebrand solubility parameters to choose gentle solvent blends that swell a varnish without disturbing paint. Spot tests, contact times, and barrier layers guide the work. Tell us which solvent myths you’ve heard—we’ll separate fact from fiction.

Chemistry of Cleaning: Varnishes, Solvents, and Gels

Rigid and thixotropic gels, nanostructured fluids, and microemulsions localize action, limiting solvent flow into porous layers. Additives control pH and conductivity for sensitive surfaces. Interested in a deep dive on gel recipes and safety? Subscribe for our step-by-step lab notes and outcomes.

Microscopy and Cross-Section Storytelling

Ethical Sampling: Minimal, Meaningful, Documented

Sampling is rare and strategic, taken from losses or edges after noninvasive tests. Every micro-sample is logged, photographed, and stored for future research. Wonder how we choose locations? Share a scenario, and we’ll map a responsible sampling plan together.

Stratigraphy Under the Microscope

Under magnification, layers glow: grounds fluoresce, glazes appear as transparent ribbons, and old retouches pop into view. Differences in particle size and binder reveal method and era. Curious about a cross-section you’ve seen? Post it, and we’ll help decode the layers.

From Data to Decisions: Linking Layers to Treatment

Layer counts influence cleaning limits, consolidation targets, and retouch boundaries. If an original glaze is ultra-thin, gentler strategies are mandatory. Want to watch a case unfold from cross-section to final varnish? Subscribe for a narrated, photo-rich walkthrough.

Structural Conservation: Keeping Paintings Physically Sound

Canvas slackens with humidity swings, wood panels warp across the grain, and boards delaminate at weak cores. Diagnosis combines raking light, moisture readings, and mechanical tests. Share your support type and climate, and we’ll suggest targeted preventive measures.

Structural Conservation: Keeping Paintings Physically Sound

Isinglass, sturgeon glue, BEVA 371, and acrylic dispersions each offer distinct strengths, temperatures, and reversibilities. Choice depends on original materials and future retreatability. Curious about adhesive aging? Ask for our accelerated-aging graphs and we’ll post comparative results.

Structural Conservation: Keeping Paintings Physically Sound

Stable temperature and relative humidity reduce stress, craquelure propagation, and flaking risk. Microclimate frames and dataloggers offer discreet protection. Want a simple monitoring checklist? Comment, and we’ll share a printable guide matched to your environment.

Retouching, Inpainting, and Color Science

Conservators use reversible paints and resins, keeping retouches detectable under UV or close inspection. The goal is legibility without deception. Wonder how we balance visibility and unity? Share an example, and we’ll discuss ethical frameworks we apply.

Retouching, Inpainting, and Color Science

Spectrophotometers quantify color in CIE L*a*b*, guiding mixes that minimize Delta E differences. Measurements complement the eye, especially under varied lighting. Interested in our color workflow? Subscribe to receive a practical template for recording readings during treatment.

Diagnosing the Damage with Data

UV fluorescence showed greasy soot across varnish; FTIR confirmed oxidized natural resin; XRF mapped lead-rich highlights under grime. Small cleaning tests established safe dwell times. Have a similar situation? Share photos, and we’ll suggest diagnostic steps.

Treatment Steps, Guided by Tests

A tailored microemulsion lifted soot without swelling the paint; localized consolidation secured flaking; final varnish evened gloss and saturation. Colorimetry tracked gains at each stage. Want the exact recipe? Subscribe for our lab notes and safety checklist.

Digital Records and Condition Mapping

High-resolution photography, RTI, and annotated maps record cracks, losses, and fills. Versioned files preserve treatment history. Want a starter template for condition reports? Comment, and we’ll send a downloadable structure we actually use.

Before-and-After Without Hype

We present progress with scale bars, lighting notes, and spectral data, avoiding misleading contrasts. Clarity builds trust with owners and audiences. Interested in responsible storytelling? Subscribe to get our image standards and metadata checklist.
