AIC's 53rd Annual Meeting

This presentation explores the challenges associated with loaning objects from institutions that stipulate stricter environmental controls than those typically maintained by the borrowing institution, particularly in the context of increasing sustainability efforts.  The Postal Museum (TPM) in London, is aiming to achieve net zero emissions by 2040, part of this is by becoming more flexible in its approach in controlling conditions, however doing this has highlighted the difficulties of balancing the needs of the collections, the desire to borrow objects and the desire to become more sustainable.

TPM, being a medium sized museum, has the ability to make decisions readily within a small Collections team.  Currently it has been trialling the reduction of plant use to control environmental conditions and has altered its temperature and humidity parameters allowing more flexibility, but without compromising care of the objects it looks after.  We are aware that larger institutions may not have the ability to make changes quite so freely.  Sustainability and reducing energy consumption is not new within the conservation sector and it seems to be the general consensus that changes should be made, however, how much of this is actually becoming a reality?

We will discuss recent case studies in which both the borrowing and lending institutions' requirement specifications varied.  TPM aims to be as flexible as possible when lending items, looking at several measures to off-set both risks to the objects as well as helping to reduce costs and energy use.  This includes minimal use of couriers, especially when the borrowing institution have qualified collection care staff on hand, to the re-use of mounts and being practical about the conditions.  Obviously, each loan is different, and measures will be determined on a case by case basis.

We would like to generate a discussion about how museums can work together better to mitigate these issues by employing alternative conservation strategies, as well as ways to get everyone working to the same standards.  The audience will be encouraged to discuss similar situations they have encountered, any negotiations held and solutions reached.  In our experience, it has been the larger institutions that have been less flexible in their requirements.  Discussions will be raised regarding how the size of the institution affects the process; are larger institutions being hampered by the organisation structure and decision-making process? Do larger institutions want to change their criteria? Or is it that Conservators working in larger institutions are less flexible due to focusing on their own area?

Obviously, there are caveats and specific examples can be found where strict controls are absolutely necessary, but in today's world it is interesting to explore what more can be done to mitigate this.

This presentation aims to contribute to the broader conversations within the museum community about how the museum sector can evolve to meet the dual goals of conservation and sustainability, ensuring the loaning of objects continues to be a viable practice.

This study presents a collaborative, multidisciplinary approach to conserving and displaying the high-quality linen Shroud of Thutmose III, which bears a rare section of the Book of the Dead. Traditionally, these texts were written on papyrus, but in this case, they were written on fine linen fabric, dating back to 1450 BC. The shroud will be displayed for the first time at the Grand Egyptian Museum-Conservation Center (GEM-CC) collection, which requires an innovative conservation approach in preparation for its first public display since its discovery. Upon arrival at the GEM-CC, the conservation team faced several challenges. It was attached to old, acidic cardboard, and its large size (4.5 m) made it difficult for conservation and display efforts. These challenges necessitated the development of a conservation strategy for the shroud using the principle of least invasive treatments, drawing on multidisciplinary expertise in conservation and scientific research. Using non-destructive techniques such as multispectral imaging, optical microscopy, X-ray fluorescence, and FTIR, the team could comprehensively assess the properties of the fabric, pigments, and overall condition of the shroud. The results revealed that the manufacturer used yellow Orpiment and Egyptian blue pigments in the upper decorative frame for the writing, and carbon black ink was used for the inscriptions. The analyses also revealed that the old cardboard backing and adhesive used had caused damage to the fabric, resulting in discolouration and darkening of the fabric. These scientific analyses informed key decisions in the conservation process, ensuring the careful removal of the acid support and reinforcement of fragile parts. The conservation team also designed a customized and secure textile mount for the shroud’s large dimensions. The innovative use of non-invasive techniques, combined with specially designed and multidisciplinary solutions, ensures the long-term preservation of this unique artefact and its proper display and beauty in the exhibition at the Grand Egyptian Museum. The study highlights the combination of scientific progress and expertise in the field of heritage conservation, demonstrating the power of collaboration in overcoming the complex challenges of studying, conserving, and exhibiting ancient textiles.
