Jonas Veenhoven is a joint PhD student at Ghent University, the University of Amsterdam and the KIK-IRPA, the Royal institute for cultural heritage in Brussels Belgium. He focusses on the molecular characterisation of Asian lacquer natural polymers and the evaluation of cleaning approaches on those polymers using chromatography and mass spectrometry. The analysis of polymerised Asian lacquers is challenging due to the complex cross-linked matrices. Pyrolysis hyphenated with gas chromatography-mass spectrometry (Py-GC-MS) is suitable for the analysis of Asian lacquers and relies on the introduction of solid samples and online thermal decomposition of the lacquer polymer into small molecules amenable to GC-MS. In this contribution the stepwise application of progressive flash pyrolysis temperatures, ranging between 300-700 °C, is presented as a useful approach to differentiate between primary pyrolysis reactions and secondary dehydration products. This optimisation has shown to improve the characterisation of the polymeric compositions of Asian lacquers and to distinguish between the different, intermolecular covalent bonds. -

Alessandra Marrocchesi graduated in 2019 with a Master’s degree in Physics from the University of Pisa. Since 2020 she is a PhD candidate at the University of Amsterdam within the EU-funded Marie Skłodowska-Curie Actions project Cultural Heritage Analysis for New Generations (CHANGE ITN). Her research focuses on the development of novel equipment and algorithms for the investigation of cultural heritage artifacts through technical photography. -

Paul van Duin is Head of Furniture Conservation and chair of the Rijksmuseum climate working group. Sustainability is one of the key priorities of the Rijksmuseum. The energy required to maintain the present climate specifications equals that of a small village. Much research has been carried out internationally to determine how far these can be relaxed without creating risk of damage. Because every object is different, this has not yet resulted in clear guidelines. Since 1,5 years the Rijksmuseum has a unique working group where conservators and engineers collaborate to advise the directors on how to save energy, both within the present climate specifications, but also by exploring the possibilities to broaden these in a safe way. The presentation gives an overview of the development of the present specifications, research carried out on wooden panels, and the approach of the climate working group. -

Sustainability is something that we hear a lot about today. As ever increasing repercussions from climate change affect not only our homes, but our heritage, cultural professionals now have the responsibility to ensure that we are thinking about not only the past - but the future. Sustainability has to be a priority. But how do we do that when we are not trained to do so? When we already have so much on our plates and are constantly pressed for time? We will explore the sustainability lens and how to integrate futures thinking into our practice and our field.
