The research and treatment of copper engravings from the collection of the Museum Plantin-Moretus, started because a large number of items has suffered from a former applied varnish layer and years of storage, which have led to an unwanted conservation state. This project is in close cooperation with the staff of the museum. Not only will there be tests executed and strategies explored, conclusions and practical applicability of the processes will be assessed together. The goal of the research is to define a cleaning- and treatment protocol for the copper engravings.All unwanted layers and substances have to be removed from their surfaces. Subsequently, an appropriate method of treating the surface has to be established to enable a proper preservation, but also the possibility for researchers and public to view the items when needed. Finally, the established protocol will be used on a part of the collection to asses its quality. A prototype of packaging will be introduced. The final protocol will enable the museum to take care of the complete collection of copper engravings and to make a new packaging and storage system for safe keeping and easy access.
