NICAS Colloquium

11May2017 12:00 - 13:00


We are very pleased to announce the next edition of the NICAS Colloquium on Thursday 11 May 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 Roberto Padoan (Rijksmuseum), researcher and beneficient of the Migelien Gerritzen Fellowship.

Next editions

Please note that the next edition of the NICAS Colloquium will be on 8 June 2017.


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

Matt Tyler - A Protean Pigment: Smalt and the Craft Process

Smalt is a pigment with a complex history; Tyler’s research is intended to answer questions about its origins and production.  Findings related to 18th century manufacturing, as well as some details on 16th century glass-making, will be presented.

Matt Tyler is currently a PhD candidate in a collaborative partnership between the University of Glasgow and The National Gallery, London. Research is focused on the historical manufacture of the pigment 'smalt', its connections to the decorative arts, and its use by an artist.

Lambert Baij - Time-dependent ATR-FTIR as a tool to monitor dynamic processes in oil paint model systems

Paintings show a plethora of fascinating and sometimes severe degradation phenomena. From a molecular perspective, paintings are a complex heterogeneous mixture of pigment particles suspended in a polymer matrix (drying oil).  The result is a metastable sitatuation where chemical reactions and transport processes are causing both visible and invisible alterations in time. Using time-dependent ATR-FTIR, we show that it is possible to measure the diffusion of solvents and capture the formation of crystalline metal soaps in model paint systems in its entirety. Moreover, the profound influence of solvents, the availability of water and the presence of pigments on metal soap crystallization is studied. These results have important implications for our mechanistic understanding of elementary chemical reactions in aged oil paints and pave the way for additional kinetics insights into the influence of environmental factors on metal soap crystallization.

Lambert Baij was trained as an interdisciplinary researcher during his bachelor of natural and social sciences at the University of Amsterdam (UvA, Bèta Gamma). He is currently employed at the Rijksmuseum and the University of Amsterdam as a PhD candidate in chemistry. His research interests include the chemistry of oil paints and in particular, the effects of cleaning on oil paints. Lambert is expanding his knowledge of analytical methods rapidly, aiming to get to the bottom of things with while keeping close contact with conservators. to ensure practical relevance of his results.
