We are pleased to announce a new, online edition of the NICAS colloquium on Thursday 26 November 2020 from 12.00 to 13.00 hrs. The colloquium will take place online through Microsoft Teams.
Throughout the year, NICAS organises a bi-weekly Colloquium consisting of two short research lectures. It provides researchers with the opportunity to present ideas for, updates on or results of their activities. The NICAS Colloquium allows people to stay informed on a regular basis about the latest developments and results of research and to exchange information and expertise.
The chair of this colloquium will be Abbie Vandivere (Mauritshuis / UvA)
The presenters are:
► Victor Gonzalez – Tracking the in-situ formation of a rare lead-carbonate in historical paintings
In 2017, plumbonacrite, a rare lead-carbonate crystalline compound was detected in high amount within Rembrandt’s artworks. A research program was then initiated, in order to decipher the chemical pathways of plumbonacrite formation within paint layers. This contribution presents the latest results of this research, obtained in the laboratory as well as at synchrotron radiation facilities. In addition to a better understanding of the chemistry at stake in lead-containing paint layers, new insights on the Old Maters recipes were obtained.
Victor Gonzalez is a chemist with a PhD obtained from the Sorbonne-UPMC University and the Center for Research and Restoration of the Museums of France (C2RMF) in Paris. After working as a postdoctoral researcher at the Materials Science and Engineering Department of TU Delft, he is currently Junior Scientist at the Science Department of the Rijksmuseum, Amsterdam, where he is involved in the scientific analysis of Old Masters materials and techniques, with a focus onthe structural study of ancient inorganic pigments.
► Frank Ligterink – Towards open heritage science
Unless you are a hacker like myself, you probably haven’t noticed that open source computing is taking the world by storm. Many teams of diverse individuals from all over the world cooperate in successful on-line communities to create amazing software tools. Free open software, for anyone to use, to learn from, and to adapt to ones own needs, equates to empowerment of us all and is a warm invitation to give back to that community for it to foster. I believe that the success of open source software projects partly is based on tools and infrastructures that enable people to cooperate efficiently. However, equally important are carefully shaped rules of conduct such as open source software licenses. There is something to be learned here. Just like open source projects, due to its interdisciplinary nature, heritage science projects require teams of divers experts to cooperate creatively. To do so successfully we need reproducibility: open data, open software, and open publications.
Frank Ligterink is heritage scientist with an education in paper conservation, physics and teaching. He has worked at the laboratory of the Cultural Heritage Agency (RCE) of the Netherlands since 1996. His research record comprises a broad spectrum of interdisciplinary topics, aimed at uniting physics, conservation and art history+technology. Research areas include foxing of paper, ink corrosion, micro-climates, cultural heritage risk management, impact of air pollution on paper, decision analysis and color science.He is currently involved in the NICAS project ‘Drawing out Rembrandt’, A framework for reconstructing the past, analyzing the present and predicting the future condition of Rembrandt’s ink drawings. The project involves research partners Rijksmuseum Amsterdam (RMA), Rijksdienst voor het Cultureel Erfgoed (RCE), Universiteit van Amsterdam (UvA) and Universiteit Utrecht (UU). Focus of his PhD research is the development and application of physical models with open source scientific computing tools to support the interdisciplinary research of historic drawings.
