The next edition of the NICAS Colloquium takes place on Thursday, 28 February 2019, from 12:00 to 13:00 in Conference Room B of the Atelier Building (Hobbemastraat 22, Amsterdam).


The chair of this colloquium will be Marjolein Koek (Rijksmuseum).


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


The colors of Vincent's inks

Frank Ligterink

Essentially all ink drawings made by Vincent van Gogh do no longer show their original vivid colors. They have either faded or turned to brown, making it difficult to appreciate the qualities of Van Gogh as a draftsman. Several years ago, the NWO-Science4Arts project ReViGo therefore set out to digitally reconstruct the original color appearance of these important drawings, based on interdisciplinary scientific modeling. This research question turned out both more difficult and more interesting then anticipated. Our research team has reported on the intricate history of early aniline dyes and on special ink sampling and UHPLC-PDA analysis. Another complication is the color physics modeling of ink colors that needs to take into account their transparent nature. What is the color of ink? In this presentation the basic aspects of transparent ink color modeling applied to Van Gogh's drawings are explained.

Frank Ligterink is scientist for the Rijkserfgoedlaboratorium(RCE) in Amsterdam. His current PhD research aims to develop open source visualization software for interdisciplinary research of historic drawings by Rembrandt and Van Gogh.


Wood for goods: unravelling the production of wooden art objects in the Low Countries during the Renaissance

Marta Domínguez-Delmás

Wood from historical art objects represents material evidence of historical timber trade and former workshop practices. The Wood for Goods project will combine dendrochronology and technical art history to study the production of art objects made of oak in the Low Countries from the 15th to the 18th centuries, opening a window to the raw materials and workshop practices of the past. Dynamics in raw material acquisition and woodworking techniques will be identified by clustering tree-ring patterns and wood-conversion features, and pinpointing timber procurement areas. Results obtained will be merged into a geographic information system to allow for the identification of patterns and shifts in supply areas and woodworking techniques through time. Through these insights, this project aims to provide scientific support for attributions to certain artists, schools or workshops, which will benefit the study of historical art objects worldwide.

Marta Domínguez-Delmás is a dendrochronologist with 20 years of experience researching living trees, and (pre)historic wood from archaeological sites, historic buildings, shipwrecks, and art objects. Currently she works at the UvA with her NWO funded project Wood for Goods.
