Where the arts meet science: Keeping the Mary Rose shipshape
The Mary Rose, a flagship of Henry VIII’s, sank off the coast of Portsmouth in 1545. Rediscovered in the 1960s, the following years saw the excavation of over 19,000 objects, culminating in the excavation of the hull in 1982. Materials vary from leather, wood, human remains to iron, bronze and lead, with items varying in size from minuscule dice to gun carriages capable of transporting 2-3 tonne cannons. The conservation techniques and strategies employed over the last three decades will be discussed, alongside new materials and methods being developed to ensure the long term protection of this important cultural heritage.

Metal Soaps in Art: from first observations towards a deeper understanding
Old master paintings as well as modern and contemporary art are subjected to changes from the moment they have been made. Discoloration, increased transparency and darkening, crumbling of the paint, paint delamination and loss: these are just some of the degradation phenomena encountered on oil paintings. This presentation focusses on the wide-spread degradation phenomena that is related to pigment-oil binder interactions, which are metal soaps. Metal soap related defects are observed in paintings by amongst others Rembrandt van Rijn, Johannes Vermeer and Piet Mondrian. Approximately 70% of paintings in museum collections are affected by metal soap-related degradation phenomena.

Creating constructive pathways to aid ethical sampling decisions in scientific research for cultural heritage
In January 2019 the Icon Heritage Science Group launched new boundary-pushing ethical sampling guidance for decision-making when removing and using material from heritage objects and sites for scientific research. Underpinned by multiple perspectives and shared understanding, this guidance offers a constructive pathway from initial sampling thoughts to project end and beyond, developed from extensive national and international consultations with a range of interested parties. In this webinar, Anita takes us through the guidance and shows how it can be put into practice through personal case studies where constructive ethical thinking and discussions have helped navigate crossroads in sampling decisions.

Carl Heron, Director of Scientific Research, British Museum
100 years of Scientific Research at the British Museum
I’m aiming to present, in 30-40 minutes, a snapshot of 100 years of Scientific Research at the British Museum. In 1920, a small laboratory was established following an enquiry into the condition of objects, largely as a result of inadequate storage during the First World War. From this humble beginning, conservation and scientific investigation developed into the significant core activities evident in 2020. This inexhaustive and rather selective presentation will highlight some examples from the annals of the department. I will end by looking forward to the period ahead.

Using online and open apps for preventive conservation
Online apps for preventive conservation are proliferating in the web. For free and with a few clicks it is possible to analyse humidity and temperature data, estimate pollutant concentration indoors, predict dust deposition rates, and many other tasks, basic and advanced. Current research projects (such as the developments around IPERION-HS and ERIHS, the European Research Infrastructure for Heritage Science) will accelerate the creation of new online platforms and improve their capabilities. In this talk, I will provide an overview, with practical demonstrations, of some of the best available online tools, and present a blueprint for future developments.

Corrosion and conservation of the Mary Rose cast iron cannon shot
This talk looks at the collection of 1,200+ cast iron cannon shot from the shipwreck of King Henry VIII’s flagship the Mary Rose (c. 1545). From their formation and burial, through to their excavation, conservation and storage, this presentation will examine how the artefacts have changed over time. Using a combination of lab- and synchrotron-based analysis methods, an overview of the material and recent experiments will be given to gain new insights into the chemistry of marine iron corrosion and the impact of different conservation approaches on the reaction.

Sustainability and Cultural Heritage: Our Past and Our Future
Sustainability is a global issue. As realities surrounding climate change and social injustice become more apparent and hit closer to home, people are ready to do something about it. But what does cultural heritage have to do with climate change? How do museums impact social justice? Why do conservators need to learn how to think green in their practice? This webinar will outline what sustainability means to cultural heritage and what unique opportunities the sector has to engage with and promote sustainability – resulting in holistic change and contributing to a sustainable future for all.

Applying alkaline nanoparticles to deacidify alum-treated wood
Conservation of waterlogged archaeological wood using alum salts (potassium aluminum sulfate, ammonium aluminum sulfate) was a method used in the past to treat highly degraded wood. It was used on the Viking Age wooden finds from Oseberg, recovered in 1904 near Tønsberg, Norway. Today this wood is very acidic (pH ≤ 2), mainly due to the acid absorbed during the alum treatment. High acidity has caused the wood polymers to undergo a slow degradation over time. In order to slow down degradation, the research project Saving Oseberg investigates retreatment methods for these finds. In some cases retreatment cannot undergo water-based methods. For such objects, we are currently testing alkaline nanoparticles (calcium hydroxide in isopropanol) to deacidify the wood. We present a background of the alum method, facts about calcium hydroxide nanoparticles and show ongoing practical work using these.

The European Research Infrastructure for Heritage Science (E-RIHS)
Much could be gained from research that is openly shared, as well as from research that is collaboratively developed. The European Research Infrastructure for Heritage Science (E-RIHS) will specifically promote the sharing of facilities where research is carried out – whether scientific laboratories, conservation workshops or art history research departments. Namely, investments into unique research facilities and expertise are much better justifiable if access to such facilities is open to external researchers. Many such facilities already exist and operate nationally and in order to reduce the risk of duplication, E-RIHS will be developed into a distributed infrastructure. This way, excellent facilities will pool some of their operational time to enable research to be carried out internationally and collaboratively, with lean central management. E-RIHS, including its UK node, E-RIHS.UK, is still actively developing and collaboration is actively promoted across the spectrum of heritage research.

Psyche on a smartphone: shining new light on a Florentine Renaissance masterpiece
INSPIRE2020 (December 2019 - March 2020) was the first exhibition of work made by primary school children at The Fitzwilliam Museum in Cambridge. The exhibition resulted from a year-long project modelled on the National Gallery’s Take One Picture, which focused on the painting of Cupid and Psyche by Jacopo del Sellaio as a source of inspiration for creative cross-curricular enquiry on the part of teachers and pupils alike. Inspired by the children’s engagement with the artist’s materials and techniques, conservators and heritage scientists undertook their own technical research on the panel. Their work was integrated in the exhibition display and in a newly-developed AR app. This talk will discuss the role played by Heritage Science in the INSPIRE project, as well as the range of opportunities that truly cross-disciplinary collaboration offers for meaningful, creative engagement of the Heritage Science community with teachers, schoolchildren and museum visitors.

Building a Skilled and Diverse Heritage Science Community
One of three key themes in the Strategic Framework for Heritage Science in the UK is the development of a skilled and diverse heritage science community. Over the past year, members of the NHSF working group assembled under this theme have been scoping partners, methods, and opportunities to begin addressing this critical priority. At this joint NHSF/ICON HS meeting, we invite two speakers to discuss opening up heritage science to the public through citizen science and strategies to diversify our community. We also invite attendees to contribute ideas and comments on this theme at our timely discussion.

Monitoring micro-changes in historic objects to support strategies for indoor climate management
Responsible management of indoor environments in museums is currently in the spotlight of cultural heritage institutions worldwide. There is general consensus in the museum community that reducing energy consumption has economic, ecological, and ethical benefits.
Since the safety of collection is the foremost priority, new climate control strategy should be scrutinized by response of objects. Recently, the GCI developed methodology employing Acoustic Emission monitoring which allows the progress of micro-fractures in objects to be directly recorded. As a consequence, AE can be used to detect physical changes in objects induced by exposure to their real-world environments and, hence, can support the assessment of adopted strategies for the museum indoor climate management.

Introduction to R and Data Science
Analysing and presenting data to inform practical solutions is a challenge for any operational preventive conservator or scientist. Data science is a growing field and free data-driven tools such as R can be used to go from data to interactive reporting tools and new insights. This will be a brief, and hopefully gentle, introduction to how R can be used to analyse the types of data typically encountered for collections care.
