NICAS Colloquium

23Feb2017 12:00 - 13:00


We are very pleased to announce the next edition of the NICAS Colloquium on Thursday 23 February from 12.00 to 13.00 hrs. The colloquium will take place in conference room B of the Atelier Building (Hobbemastraat 22, Amsterdam).

The chair of this colloquium will be Alessa Gambardella (Rijksmuseum), postdoctoral fellow.

The presenters during the colloquium are:

  • Selwin Hageraats - Synchrotron photoluminescence microscopy and microspectroscopy to study zinc white degradation in oil paint

The degradation of zinc white pigment into zinc soaps has caused a variety of problems in modern and contemporary oil paintings, including discoloration, delamination, protrusion and even flaking of paint layers. Synchrotron photoluminescence microspectroscopy and multispectral microscopy have been applied to visualize these phenomena in high spatial and chemical detail. These techniques have shown the ability to distinguish zinc whites from different production processes, image zinc soap distributions at sub-micron resolution and simultaneously probe a variety of other commonly used pigments. Current research is focused on understanding the interface-specific degradation phenomena found to occur in some works of Mondrian, and the development of computer-based analysis procedures that will aid in relating the chemistry of a sample to its corresponding multivariate luminescence patterns.

Selwin Hageraats recently graduated from Radboud University with a degree in Natural Sciences. He started his PhD in September at the Rijksmuseum in cooperation with IPANEMA, a French research platform for the study of ancient materials. In his research he works on applying novel, synchrotron-based techniques to gain insight into the degradation of zinc white in oil paint. The project is privately funded by the Bennink Foundation.

  • Huub Baija - Netherlandish Picture Frames from the Gothic to the Dutch Golden Age

This research concentrates on original painted and gilded finishes of surviving Netherlandish picture frames from the 15th,16th and 17th centuries. The central research question is: ‘What did early Netherlandish picture frames originally look like in combination with their corresponding paintings?’  Chronologically, the study includes framing in the Burgundian Netherlands, style transition in frames from Gothic to Renaissance, Iconoclasm and picture framing, and picture frames during the gestation of the Dutch Republic.

Hubert Baija studied educational sciences and art history at the University of Amsterdam, studio art and art history at the Rijksakademie van Beeldende Kunsten (Amsterdam) and technical writing at the University of California (Berkeley). Hubert joined Rijksmuseum to become the senior conservator of picture frames and gilding. He taught and coached hundreds of conservation students. Since 2016 he continues his research at the Rijksmuseum as a PhD candidate in conservation science at the University of Amsterdam.
