NICAS Colloquium

12Oct2017 12:00 - 13:00


The next edition of the NICAS Colloquium takes place on Thursday, 12 October 2017, from 12:00 to 13:00 in conference room B of the Atelier Building (Hobbemastraat 22, Amsterdam).


The chair of this colloquium will be Paolo D'Imporzano (VU University), PhD candidate within the NICAS project Multi-isotopic analysis of early modern art (MITEEMA).


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

Herman den Otter

Reading art technological sources. The case of Roubo's Art du menuisier

When making use of art technological sources in conservation related research, proper attention needs to be paid to the source's qualities: why was it written, by whom, for whom, was it original work? By trying to find answers to questions such as these, Den Otter has brought together a great deal of information about Roubo's L'Art du menuisier, an eighteenth-century source on fine woodworking that has been consulted time again as a prime art technological source in furniture conservation. The lack of a critical evaluation of Roubo's work has too often led to incorrect interpretations. Careful reading of the text and researching the book's historical background sheds new light on interpreting eighteenth-century woodwork with the help of art technological texts of this type.

Herman den Otter is a lecturer at the University of Amsterdam, teaching Conservation and Restoration of Wood & Furniture. His study on L'Art du menuisier was the subject of his PhD-dissertation and was published in 2017

Time-dependent ATR-FTIR studies on the release of solvents from cleaning gels into model systems of oil paint binding media

The use of gelled systems for the cleaning of paint surfaces aims to regulate the cleaning action by the controlled application of solvents. Assumed benefits include controlled solvent release at the surface and limited extraction of soluble paint constituents. Rigid gels have the added benefit of reducing mechanical action and they typically leave no gel residues behind. A method was developed based on time-resolved Attenuated Total Reflection Fourier Transform Infrared spectroscopy (ATR-FTIR) to compare the diffusion of free (organic) solvents and solvents released from cleaning gels. Using model systems of oil paint binding media based on zinc and lead ionomers, the diffusion of free solvents and solvents released from three gels was measured and compared. Minimal or no solvent retention caused by cleaning gels was found with this set of data.

Lambert Baij was trained as a chemist and interdisciplinary researcher. He is currently employed at the Rijksmuseum and the University of Amsterdam as a PhD candidate in chemistry supervised by prof. Piet Iedema and dr Katrien Keune.
