Esther van Duijn

Red, white or blue – an evacuation priority marking system on paintings in Dutch museums

Red, white and blue dots (with a diameter of circa 50 mm) painted on the reverse of paintings are well known to painting conservators at the Rijksmuseum. However, information about the dots, their origin and purpose has been incomplete. The purpose of this paper is to present new information about this marking system, making it possible to date the dots within a period of months. This presentation was first given together with Stina Ekelund at the ICOM-CC triennial meeting in Copenhagen earlier this month.

Esther van Duijn is paintings conservator and researcher. She obtained her PhD in 2013 at the University of Amsterdam, where she studied the painting technique of gold-brocaded velvets in Early-Netherlandish painting. She is now working on a three-year project studying the conservation history of the paintings collection of the Rijksmuseum, financed by the Luca fund.

Sanneke Stigter

A behaviour index for complex artworks – a conceptual tool for contemporary art conservation

This project is based on a theoretical model that suggests that an artwork’s ‘behaviour’ may change over time depending on the prevailing attributed values during decision-making on presentation strategies and conservation measures of complex artworks, rather than that the type of behaviour is inherent to the artwork. Within the NWO funded project 'DIAL for Complex Artworks: A Digital Index for an Artwork's Life' the idea is translated into a practical digital interactive tool that can be implemented in a collection database system. The idea is that this not only provides insight into the artwork’s biography to learn from past iterations, but especially to enforce accountability from those having to make decisions in the near future about an artwork’s appearance, foregrounding the dynamics that are taking place when data are interpreted and used in practice.


Sanneke Stigter is Assistant Professor in Conservation and Restoration of Cultural Heritage at the University of Amsterdam, directing the specialisation Contemporary Art since 2007. Prior to this position she headed the Conservation Department of Contemporary Art and Modern Sculpture at the Kröller-Müller Museum. She obtained a PhD for her work on the Conservation of Conceptual Art in 2016.
