Historic mosaics require particular conservation care. The Glasmalerei Dr. H. Oidtmann restores wall and floor mosaics made of natural stone and glass smalti with sound expertise.
Loose tesserae are secured, missing areas are supplemented with appropriate materials and surfaces are gently cleaned. Every task is based on a precise analysis of the existing fabric, technique and condition.
Notable projects include the restoration of the mosaics in the octagon of Aachen Cathedral, carried out with the utmost precision and in close collaboration with heritage conservation.
