To test and develop an efficient matrix for monitoring, imaging and documenting (art-technical), fragile historic mixed media objects, the ArtGarden research project will focus on several case studies. Due to the specific conservation and preservation problems, the Enclosed Gardens will serve as a first case study to study historical mixed media. In a later stage these findings will be applied to other mixed media artefacts. Every object will be subjected to profound art historical and art technical research. All preliminary findings on these case studies will be shared here!
