We are very pleased to announce the first NICAS Colloquium on Thursday 15 September from 12.00 to 13.00 hrs. Robert van Langh, chair of NICAS, will be the first chair of the colloquium. The colloquium will take place in conference room B of the Atelier Building (Hobbemastraat 22, Amsterdam).
The presenters during the first colloquium are:
- Indra Kneepkens - Pressing oil matters: About the influence of pressing and storage on the properties of linseed oil as a binding medium in panel painting
In this presentation Kneepkens will go into the practical aspects of pressing and storing linseed oil for the purpose of making historically accurate reconstructions. Furthermore she will present the results of recent experiments about the preparation of sun-thickened linseed oil based on late medieval recipes. The results of these experiments may have implications for the relation between art technological sources and historical painting practice.
Indra Kneepkens obtained her Master’s degree in Art History at the University of Amsterdam in 2012. Since 2014 she has been working on a PhD thesis about late medieval recipes for the processing of linseed oil for use as a binding medium in panel painting, at the Amsterdam School of Historical Studies (ASH) of the University of Amsterdam, under supervision of Arie Wallert and Claudine Chavannes.
- Guus Verhaar - Weeping Glass: The identification of ionic species on the surface of unstable glasses
In this presentations Verhaar will consider the identification of deterioration products on the surface of unstable glass in museum collections. Ionic species have been identified using Ion Chromatography. The identification of chemical compounds on unstable glass provides crucial information with regard to the conservation of historic glass in museum collections, in particular the choice of a suitable level of relative humidity for display and storage.
Guus Verhaar obtained a BSc in physics and astrophysics at the University of Amsterdam and a MA in Conservation of Cultural Heritage in the specialization Conservation Science, also at the University of Amsterdam. He is currently carrying out PhD research in Conservation Science at the Amsterdam School for Heritage, Memory and Material Culture at the University of Amsterdam in close collaboration with the Rijksmuseum under supervision of Norman Tennent and Maarten van Bommel.
