Due to environmental damage, overpainting, thermal insulation and widespread ignorance, sgraffito decorations are seriously threatened in their original existence:
Often only small parts of the original elements have survived. A European cooperation is therefore necessary in order to quickly get the problems of practical restoration under control as well as to adequately highlight their cultural and historical significance.
The Hornemann Institute promotes a European network for research into sgraffito in terms of its materials, techniques, themes and conservation strategies. The joint exchange serves the quality assurance of the restoration of sgraffito decorations:
The project title "Sgraffito in change" is deliberately ambiguous: On the one hand, it is about the analysis of the thematic as well as material/technical change from the Middle Ages to the late 20th century.
On the other hand, it also deals with the change in the stock of preserved sgraffito decorations, which almost all examples have experienced as a result of later conservation measures.
So far there have been two conferences, a third is planned for 2021 in Segovia:
Sgraffito in Change. Materials, Techniques, Themes and Conservation / Materials, Techniques, Topics, and Preservation.
