The next edition of the NICAS Colloquium takes place on Thursday, 8 October 2019, from 12:00 to 13:00 in the main room of Het Bureau (Hobbemastraat 20, Amsterdam).


The chair of this colloquium will be Klaas Jan van den Berg (Cultural Heritage Agency of the Netherlands).


The following presentations are scheduled for this edition of the NICAS Colloquium:


Improved micro-fading device for risk assessment of colour change in Van Gogh’s works

Gauthier Patin

Over the past two decades, conservators and curators have often noted colour changes in Van Gogh artworks. The light-sensitive pigments responsible for these colour changes have been identified and their degradation mechanisms investigated. Yet, our actual knowledge of the time-scale of this problem is rather limited. To what extent has the observed fading and discoloration in Van Gogh’s paintings now stabilized? And if still ongoing, how fast does it occur? In other words, can we expect to see colour changes taking place in Van Gogh’s artworks over the next ten years or so? The present 4-years PhD project, sponsored by the AXA Research Fund and the Van Gogh Museum, will implement an imaging micro-fading tester (iMFT) in order to study the fading properties of paint and writing materials used by Van Gogh. In collaboration with the RCE (Rijksdienst voor Cultureel Erfgoed) and the Rijksmuseum, the first part of the project will deal with the improvement of the micro-fading device, such as the implementation of a co-axial system for the fading and colour measurement processes. In a second phase the improved micro-fading device will be applied on paint samples, ranging from model paint-outs to real Van Gogh paintings. The outcomes of the research will contribute to development of an improved model for light exposure risk assessment of Van Gogh paintings and will ultimately benefit the long term preservation of Van Gogh artworks.

Gauthier Patin is

currently a PhD student at the University of Amsterdam. He graduated in 2014 with a Master degree in paper conservation from the Paris 1 Panthéon-Sorbonne university. Following on from his master thesis on micro-climate issue, he worked in the Rijksmuseum (Amsterdam) and in the Atelier für Papierrestaurierung (Cologne).



Climate4Wood – what is a sustainable museum climate?

Paul van Duin

The Climate4Wood project is aiming to help museums to define a sustainable museum climate, by studying the
behavior of wooden panels in furniture and paintings. The project is funded by NWO, as part of the Science4Arts
Program. It brought together scientists and conservators. This presentation will mainly focus on the so-called museum
study, what we can learn by close observation of the material aspects and condition of museum objects, by analyzing
the damage patterns in panels in furniture. Not only in the Rijksmuseum, but also in Castke Amerongen, where the
climate fluctuates much more. Later this year the research on modelling and moisture transport in wood will be
presented by Rianne Luimes and Thomas Arends of TU Eindhoven.

Paul van Duin is head of furniture conservation of the Rijksmuseum.
