  Abstract:  

Gas chromatography coupled with mass spectrometry (GC-MS) was used to investigate the organic materials of painted coffered ceilings of five medieval churches in different regions of Transylvania, applying a methodology designed to identify organic binding medium in the same microsample. Results showed a very restrained use of organic materials since only animal glue was identified in most of the samples. The study provided a better understanding of the painting technique and of the decay processes of this specific local heritage, and proved helpful in the planning of suitable conservation strategies.

Keywords: GC-MS analyses, organic binders, animal glue, painted ceilings, Transylvanian heritage
