The next edition of the NICAS Colloquium takes place on Thursday, 8 June from 12:00 to 13:00 in conference room B of the Atelier Building (Hobbemastraat 22, Amsterdam).


The chair of this colloquium will be Martine Posthuma de Boer (TU Delft), a researcher specialising in the conservation of gilt leather.


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

Consolidating Adhesives for Flaking and Fragile Paint Layers of Cultural Objects

A variety of adhesives have been used to restore paintings, sculptures, and other cultural objects. The glues used include natural and synthetic materials that may degrade over time, resulting in discoloration and changes in mechanical properties. Few adhesives have been formulated for the specific needs of each restorative task and little is known about the fundamental adhesive properties required for such applications. Our research focuses on understanding the physical, chemical, and mechanical properties of commercially available adhesives used for the conservation of paintings. Building upon the knowledge obtained, new adhesive systems will be developed with known initial and aging properties for the unique needs of conservators.

Chelsey Del Grosso is a postdoctoral research scientist at the Adhesion Institute of TU Delft working under Hans Poulis and René de la Rie. In 2016, she received her Ph.D. in inorganic chemistry from Purdue University in the laboratory of Jonathan J. Wilker. Her work focused on the formulation and development of marine coatings to decrease biofouling and reduce marine mussel adhesion to underwater structures.

The world in painting: The big world painted small and pictorial strategies in the 17th and early-18th centuries

The treatise The big world painted small (1692), written by painter Willem Beurs, was not intended as a workshop handbook, nor was it literature on the nobleness of the liberal art of painting. With Beurs the reader is taught how to paint, step by step. The build up of the book, the to-the-point instructions and the emphasis on still-life painting are distinguishing features. Furthermore, Beurs attends to contemporary natural philosophy (i.e. science) to clarify some painting principles. I will discuss some of these aspects, together with 17th- and 18th-century examples of paintings and painting reconstructions. On June 6th, members of the project team, including myself, will have examined paintings that were made by Beurs’ pupils: four wealthy dilettantes in Zwolle. I hope to include some of our findings (IR and XRF) in the NICAS lecture.

Lisa Wiersma is a PhD candidate in the NICAS-project Recipes and Realities: An analysis of texture rendering in still-life painting and the pictorial procedures of Willem Beurs at Utrecht University.
