Preserving Medieval Frescoes in Carinthia
Reading Time: 1:40 min
Preservation focuses on preventing further damage rather than making the fresco look new. Key strategies include:
Environmental Control:
– Ensuring stable temperature and humidity in chapels and towers.
– Installing protective roofs, drainage systems, or barriers against wind and rain.
Preventive Conservation:
– Regular inspections to detect early signs of deterioration.
– Careful cleaning and monitoring for mould, salt crystallisation, or insect damage.
Limiting Exposure:
– Controlling visitor numbers or restricting access in fragile areas.
– Using indirect lighting to prevent fading of pigments.
Research and Documentation:
– Detailed studies of pigments, plaster composition, and historical painting techniques help conservators plan interventions without altering authenticity.
Each fresco is treated individually, often guided by the original techniques and materials used in Romanesque and Gothic periods. This ensures that the fresco remains both a historical document and a living piece of cultural heritage.
Restoring Medieval Frescoes in Carinthia
Restoration of medieval frescoes in Carinthia is a careful, step-by-step process aimed at bringing the artwork closer to its original appearance while preserving its historical integrity. The main steps usually include:
Examination and Documentation
– Experts carefully examine the fresco to understand its condition.
– They document every detail, including cracks, flaking paint, or areas where the plaster has fallen off.
– High-resolution photographs, infrared scans, or UV light are often used to reveal hidden layers or earlier sketches.
Cleaning
– Dirt, soot, and old restorations are gently removed using soft brushes, mild chemical solutions, or laser cleaning.
– This is done very slowly to avoid damaging the fragile pigments.
Consolidation
– Flaking plaster and pigments are stabilised.
– Conservators inject special adhesives behind loose plaster or apply fixatives to secure pigments to the wall.
Filling Losses
– Areas where plaster has fallen are carefully filled with lime-based materials compatible with the original wall.
– This ensures structural stability without introducing modern materials that could harm the fresco.
Retouching
– Missing colours are sometimes carefully inpainted using reversible paints, so future conservators can remove or adjust them without damage.
– Conservators often follow the principle of “distinguishable but harmonious,” meaning new paint is slightly lighter or different when seen close-up but blends at a normal viewing distance.
Protective Measures
– A protective layer may be applied to shield the fresco from humidity, dust, or UV light.
– In some cases, microclimate systems are installed in chapels to control temperature and humidity.
