Chemische und biologische Untersuchungen im Zusammenhang mit der romanischen Bilderdecke von Zillis

Abstract

The famous romanesque painted ceiling of the church of Zillis consists of a wooden framework. Various defects at the painting made microbiological and chemical examinations indispensible to enable a professional restoration. Chemical analysis of binding media was carried out and attacking microorganisms were determined. Now it is possible to restore the paintings with knowledge about ancient binding materials and possibilities to stop biodeterioration by use of suitable microbicides.
