“…Historic photographs were compared to the present condition of the object in order to analyse the development of damage over time as suggested by Michalski (1996). It was accepted that a large part of the condition assessment was ambiguous, as pointed out by Taylor and Stevenson (1999), but the long experience of the conservators increased its reliability.…”

“…Panel paintings as well as panels in furniture have been chosen, because together they can provide more information on wood, the core material. Decorated panels are seen as particularly vulnerable to fluctuations in climate due to the wood construction (Michalski, 1996;Van Duin, 2009;New, 2014).…”

[heading]Museum objects are often highly complex and composed of materials with varying properties, some of which may have changed as a result of ageing and/or conservation treatments. Research into defining sustainable environmental conditions by balancing energy cost and risk to these vulnerable objects, has mainly focused on experiments in laboratories with new, single materials or on computer modelling, but only to a limited extent on actual objects. This paper presents a method to collect empirical data from a large group of decorated wooden panels in order to investigate the effects of humidity fluctuations on these objects and relate them to their material properties and construction. Wooden panels were chosen as they are regarded to be particularly sensitive to fluctuations in relative humidity. The fluctuations may cause the wood to shrink and swell and can result in open glue joints, cracks and deformation of the panels as well as losses and cracks in the decorative layers. Empirical data are scarcely available as yet but are essential to study relationships between material properties, type of construction, damage and as input and validation for modelling and experimental studies. The method, referred to as the Rijksmuseum Study, was performed on a group of 300 objects from the furniture and paintings collections of the Rijksmuseum.

Heritage-related guidelines and standards recommend stable climatic conditions, since these contribute to the extension of heritage collections life. As a result, numerous museums and other heritage institutions implement (expensive) mitigation measures to achieve stable conditions. Nevertheless, temperature and relative humidity fluctuations are often still observed. This contribution demonstrates that the analysis of temperature and humidity peaks and drops helps to identify hazards which cause fluctuations in different frequency ranges. This hazard identification provides information on the type of mitigation actions that are required in the near future and in which order they need to be implemented. The approach is illustrated with a case study. A 22 month monitoring campaign was performed in a chapel in the center of Antwerp (Belgium) where the climatic conditions are controlled with a heating, ventilation and air conditioning (HVAC) system. Low-, mid-and high-frequency fluctuations were separated and discussed for their hazards.

“…Panels in furniture are often decorated with (plain) veneers or, as marquetry, with different wood grain directions or with molding(s) of various thicknesses. Restraint is a central aspect for understanding the changes of or damage to decorated wooden panels and has been discussed by several researchers in the literature (Michalski, 1996;. The influence of restraint on the shrinkage and swelling behavior of wood has been taken into consideration by furniture and panel makers historically and is still considered today.…”

<div>In late 2016, “The Mechanics of Art Materials and Its Future in Heritage Science: A Seminar and Symposium” was held at the Smithsonian Institution’s historic Arts and Industries Building. Organized by the Smithsonian’s Museum Conservation Institute (MCI) and the Royal Danish Academy of Fine Arts, Schools of Architecture, Design and Conservation, the two-day event brought experts in mechanics research from across the globe to discuss current and future trends in the study and preservation of cultural heritage. Speakers represented a continuum of innovative mechanics research in the cultural heritage sector, from its origins at the Smithsonian to current professionals working to shape the field and train future generations of scholars. The event began with the popular paint mechanics workshop created and taught by MCI senior research scientist emeritus Marion Mecklenburg, condensed into a single-day seminar of lectures and discussion. The second day featured an international group of speakers and case studies on the state of mechanics research around the globe, with an afternoon program focused on emerging U.S.-based speakers and their thoughts on the future of the field. This volume reflects a collaborative view of cultural heritage research in mechanics; beginning with a review of mechanics research at the Smithsonian Institution and followed by the nine papers presented by the symposium speakers, this publication incorporates the work of 15 national and international research centers. The Appendix includes a bibliography of Dr. Mecklenburg’s publications and his previously unpublished 1982 report on the mechanical behavior of painting materials.</div>
