During lockdown our teams, like everyone, have had to adapt to new ways of working and think creatively about how we continued to support our heritage community and maintain our statutory services. In Part 1 Neil and Dorothy shared some of the work done by the Archaeology team and Wiltshire Buildings Record. In Part 2 we turn the spotlight on our Archives and Local Studies team, the Conservation and Museums Advisory Service and the Heritage Education Service.
Archives and Local Studies
While lockdown forced the cancellation of our 2020 events programme, we were able to reinvent some of the activities in new formats. County Librarian Julie Davis had planned a talk on TheHome Front in Wiltshire, as part of the celebrations for the 75th anniversary of VE Day in May. Instead she turned her slides into an online film show with a recorded narration. Julie also recorded readings from her recent publication From Blackout to Bungalows which explores the effects of World War Two on Wiltshire. These are available on our VE Day page on the website.
Pre-lockdown we were delighted to host a display of artworks by students from Wiltshire College in the History Centre foyer. Community history advisor Joy Bloomfield, who worked with the college on this project, redisplayed the pieces in our search room and created a more widely-accessible online exhibition available via our Facebook page.
Julie's Memory Box sessions also went online. Before lockdown the group would use written sources as a springboard for discussion and reminiscence. Unable to meet physically Julie recorded several readings themed on local fairs and industries which are now online to be enjoyed at home. Similarly, Ian Hicks has replicated his popular Introduction to Ancestry.com sessions as online videos. All videos can be found on our youtube channel including four short Welcome Back films featuring members of our team. Creating video content is new for most of us at the History Centre and, we’re not afraid to say, it was a bit daunting to begin with, but we have learnt new skills, gained confidence and seen the benefits of developing online content for the History Centre. Watch this space for more online material over the coming months.
We have also used lockdown to add more content to the Know Your Place website. Scanned copies of our tithe awards have been added to this already brimming resource. The tithe awards give details of landowners and occupiers plus land use for parishes across the county. In addition, more content has been added to pages of the Wiltshire Community History website, most notably on the subject of Wiltshire schools. Julie has also continued her engagement work with the team of Wiltshire Libraries Local Studies’ Champions to create digital material for the library service's YouTube channel.
Lockdown resulted in the disruption to many arts, heritage and cultural projects but as restrictions eased organisations looked to restart their programmes. The History Centre is delighted to be working with our new partners at Celebrating Age Wiltshire on their lottery-funded project to improve health and wellbeing of older people living in isolation. We are also feeding into the Swindon Heritage Action Zone, which is part of a wider Historic England heritage project and the project officer is working with local people in and around Swindon’s Railway Village to post old photographs onto the community layer of Know Your Place website.
Visitors to the History Centre usually come to consult documents, but the Local Studies Library is also an important research tool. It contains over 50,000 volumes and is the largest collection in the world of books about Wiltshire. We are always on the lookout for new titles and actively collect any published work that is about Wiltshire or is written by someone with a strong Wiltshire connection.
The last few months have been an opportunity to catch up with the backlog of cataloguing, making over 100 new books available to users of the service. They include biographies; newly published research on the two world wars and a beautifully illustrated book of the plants found in the gardens of Salisbury Cathedral Close. Perhaps these books may inspire you to write something and be part of Wiltshire’s written history. New lists of our latest catalogued books can be found in our Local Studies newsletters.
We have also used this time to update our staff toolkit which contains key guides on various collection themes in the hope we have the answers to all your questions at our fingertips. Quite an undertaking, we’re sure you’ll agree. Colleagues have also conducted research on topics such as militia records, the architecture of Salisbury and the Kennet and Avon Canal, plus we have been putting the finishing touches to a major new catalogue for the archive of Westinghouse Rail. This has involved formatting data collected by our volunteer Mike and uploading onto our electronic catalogue.
Like most archives and museums, we have launched a new collection that will record the impact of the COVID-19 pandemic on our lives. The History Centre’s Living in Lockdown project aims to collect personal reflections from people in Wiltshire and Swindon on their experiences of Covid-19 and how it has affected daily lives. We are also looking for printed material such as posters and leaflets, or newsletters from local groups, plus photographs recording lockdown, such as public displays of art and craft, and how local shops, services and events have been affected. Read more about the collecting project (including how to get in touch) on our archives pages.
Conservation and Museums Advisory Service
The Conservation and Museums Advisory Service (CMAS) aims to promote excellence in the care and use of collections by providing conservation advice and practical treatments to heritage organisations and the public. We also support museums in Wiltshire to meet professional standards and become sustainable, resilient organisations.
Based at the History Centre, we can normally be found working in our two conservation laboratories, or out and about giving advice to museums, archives and historic houses. Lockdown meant that, like many others, we were confined to working at home and had to find a whole new way of doing things.
Without access to the specialist equipment and chemicals in the laboratory, we had to stop carrying out practical conservation treatments such as x-raying archaeological finds, cleaning coins, reconstructing ceramics and repairing documents. Instead the conservators have taken the time to carry out a number of other tasks.
We have been developing new training and support packages for both staff at the History Centre, and other museums and archives looking to gain Accreditation or better care for their collections. This includes topics like pest management, environmental monitoring and control, collection care planning, and preventative conservation of archives and historical collections. We’ve been looking at services aimed at those involved with archaeology, such as archaeological contractors and metal detectorists. There has also been the opportunity to develop our environmental sustainability plans, becoming greener to help the Council meet its pledge to become carbon neutral by 2030.
Even though the building has been closed, the archives have still required some care and attention, so we’ve been carrying out regular environmental monitoring checks to make sure the temperature and humidity levels in the strong rooms is suitable for their long-term preservation.
We have been exploring the digital world and finding alternative ways of working. A redesign of the CMAS web pages has begun including a simplified web address - www.wshc.eu/cmas - and we took part in a twitter conference organised by the Institute of Conservation (#IconArchTC) talking about our treatment of a Roman coin hoard owned by Athelstan Museum, Malmesbury. You can also watch our new video about the conservation treatment of a pair of Pele’s football boots.
Meetings have gone online, and we have been getting to grips with the technicalities and etiquette of virtual meetings, including Wiltshire Museum Group get-togethers. The team has also been available by telephone and email to answer questions and give advice to organisations and the public about all things conservation and museums.
Wiltshire’s museums have been hit hard by the lockdown, with the cancellation of events, loss of income, and other challenges that come from having to close their doors overnight. Working with South West Museum Development, we have supported them throughout the last few months, answering enquiries to help them look after staff, volunteers and collections, providing information about the latest government guidance, and encouraging applications for the grant funding available. This has continued as museums have started to re-open. Museums in the county have been working hard to address the issues and several have now welcomed back visitors, with special measures put in place to keep everyone safe: Wiltshire Museum, Chippenham Museum, Boscombe Down Aviation Collection, REME Museum, Salisbury Museum, The Rifles Museum, Crofton Beam Engines www.croftonbeamengines.org. More will follow in the not too distant future.
Although the CMAS team is now back in the building and the laboratories, we’re not quite back to normal! It’s likely to be a little while before we’re able to make visits to organisations or carry out face to face training. So, in the meantime, we’ll carry on developing our digital delivery and because we love showing off the work we do we’re planning to add more case studies, videos and a virtual tour of the laboratories to our web pages soon.
Heritage Education Service
As heritage education officer I work with schools and community groups providing facilitated sessions in schools, community settings and at the History Centre. All those face-to-face sessions ended with lockdown. The other aspect of my work involves creating classroom and online resources – and this has very much continued.
In anticipation of the lockdown the History Centre could see that digital resources – our website, blog and social media platforms – would be our way of keeping some of our services operational and allow us to stay in touch with our community of users and volunteers. With that in my mind my role morphed into coordinating the History Centre’s digital services and joining with colleagues in Libraries and Leisure to develop and deliver online services to replace, as best we could, the wide range of physical services provided by our teams. This resulted in the Active Communities webpages and a host of downloadable resources on the Wiltshire Council website.
As our services resume, with new policies and procedures in place, my work on the History Centre’s digital strategy will continue alongside creating classroom resources for teachers. I am also delighted that many of the projects we support are getting back on track, including the Salisbury Soroptimist’s Her Salisbury Story project (funded by the National Lottery Heritage Fund) celebrating the women of Salisbury past and present. I will be providing support and training to the group and their volunteers as they work on this wonderful project.
After meticulous planning and much hard work we are delighted to have welcomed out first visitors back into the search rooms on 25th August. Making sure the History Centre is COVID-secure for staff and visitors does mean we have had to put in new procedures for accessing our services and these follow national guidelines and regulations. We are now operating an appointments-only system for accessing our services and face coverings are mandatory for all visitors. To book your archives and local studies visit go to our website. http://wshc.eu/visiting-the-centre.html For other teams please telephone ahead to make an appointment.
I have been working as a Conservation Assistant at the WSHC for nearly a year, and a large part of my role involves administration and financial processing. However, one of the more interesting and slightly unusual aspects of the job is the hands-on work I get to do as part of the Conservation and Museums Advisory Service here at the centre, and I have recently undertaken training to use the x-ray machine which we have in the lab. This is a complex process which requires stringent processes, records and maintenance checks to ensure the machine is used safely and functioning correctly. Regular use of the equipment is key to building experience and a ‘feel’ for the items being investigated and how to get the strongest images.
How it works
Inside the x-ray machine is an x-ray tube. A heated filament called a cathode sits inside the tube and accelerates high energy electrons at a metal target anode, usually made of tungsten, as the electrons strike the anode they interact with the atoms. In this process, which is called Bremsstrahlung (braking radiation), the electrons lose much of their energy and a photon x-ray is produced. X-rays are electromagnetic radiation of a short wavelength and high frequency invisible to the human eye, but possible to record on photosensitive film, known as x-radiographs.
The object to be x-rayed is placed on top of a cassette which holds the photosensitive film. On exposure the x-rays will penetrate through the object leaving the image captured on the film. The x-rays are partially absorbed, “attenuated”, by the denser materials such as bone or metal and pass more easily through soft material such as soil or skin. Therefore, the strength of the x-ray (KV) and the length of time the object is exposed for is adjusted for the type of material, size and condition of the item.
The photographic films then require a wet, chemical process similar to that used for black and white photographic film with a developer solution to reveal the image, followed by a fixer to secure the image and a wash to remove all chemical residues. This process takes around an hour and half and must be carried out in the dark room, with only red light, which can be a little disorientating at first!
Digital or computed x-radiography is well established and allows greater speed in reviewing and manipulating images. CMAS are actively working to move to digital, so watch this space!
How X-radiographs are used in conservation
X-radiography produces images on a 1:1 scale which allow the conservators to investigate the structure, manufacture or identity of an object. Small dark bubbles can indicate casting processes, the distinctive herringbone structure of pattern welding or wave formations of damascening are often clearly visible in x-rays, even when the surface of a blade is severely deformed.
Moreover, x-rays pass more easily through deteriorated materials and voids, these areas will appear darker grey or black compared to the brighter white of more stable areas. This can show up pitting, cracks and breaks assisting in the accurate assessment of the condition of items and their longer-term conservation requirements.
X-radiography is a non-destructive way of retrieving and revealing information and so it is commonly used in the primary stages of investigation.
Quite often I come across interesting things as I go about my business in the strong rooms at the WSHC. Today was no exception when I discovered this rather odd-looking book. On first glance it appears that someone has rather hurriedly wedged a large book into a small bag but on closer inspection I discovered I was looking at a medieval chemise binding.
The binding contains an Act and Memoranda Book for the Tailors’ Guild of Salisbury including byelaws, admissions of freemen and apprenticeship indentures, dating from 1444-1838 and gives us a wealth of information regarding their organisation and activities.
It is big and extremely heavy and has a particularly large piece of leather skirting along the tail edge (lower edge). It has visible sewing stitches along the edges and two metal clasps on the foredge (front edge) that attach to corresponding slits in the cover. The book dates from 1444 so is most likely an original medieval binding, although more recent sewing repairs are visible around the edges. The text block pages are made from parchment and contain varying manuscripts, some with illuminations.
A new project recently appeared in the archive conservation lab: a brittle and damaged looking document that turned out to be an interesting new accession.
Letter Sent to Francis Yerbury, 14th May 1747 (1387/1697)
The document is a letter sent to local Clothier Francis Yerbury in 1747. It is thought that he may have run a cloth mill in Trowbridge although the letter is about a mill in Bradford-On-Avon. Hanne Dahl, Exhibitions and Collections Officer at Trowbridge Museum has transcribed the letter and below gives an overview of the its content:
The letter seems to consist of two messages. One is regarding a cloth order which John Howell has received and is ensuring Francis Yerbury he will pay for. The other is a new cloth order for the Empress of Russia of Clergy cloth in scarlets and greens. 5 cloth samples of Yerbury’s are attached to the letter as a colour reference. The Empress mentioned was probably Elizabeth of Russia who lived 1741-1762. According to popular history clothing was the chosen means in Elizabeth’s Court by which to display wealth and social standing and according to historian Mikhail Shcherbatov (1733-1790) her court was “arrayed in cloth of gold, her nobles satisfied with only the most luxurious garments, the most expensive foods, the rarest drinks, that largest number of servants and they applied this standard of lavishness to their dress as well.’ Hanne Dahl, Exhibitions and Collection Officer, Trowbridge Museum April 2019
The new accession was passed on to the archives here at WSHC by Hanne after being in the care of the Ponting family; the late Ken Ponting being former Managing Director of Samuel Salter Ltd. weaving mill in Trowbridge.
As is often the case with the documents I work on, there is much of historical interest and I could spend many hours researching them. However, as a conservator, once I have enough detail to inform my conservation decisions, I must tear myself away from the fascinating historical insight and prioritise stabilising and preserving the letter so that future researchers can access it safely.
It was originally folded to be posted and has the postal address visible on one of the folded sections. The letter is written in brown ink and has textile samples and a small part of a wax seal attached.
Several factors made this a conservation challenge; not only was the paper extremely thin and fragile but the additional attached textiles samples and seal remains also had to be considered at all times as they could easily become detached and lost.
The document needed to be packaged so that it could be safely stored in the archive but also handled without the risk of further damage. As the paper was so thin, it could easily tear again with further handling, even after conservation.
I decided that once repaired, the document would be safest inside a mount- this would allow for compensation of the thickness of the attached textile samples and seal remnants as the depth of the window mount would prevent them getting squashed or dislodged in storage. It would also enable easy viewing as and when required without direct handling of the letter. Text found on the back of the letter was all in one area so the mount could be adapted to have a viewing window on the reverse. This would also mean the document didn’t need to be taken out of the mount or handled to see this.
Areas of damage on the letter
The letter arrived with us inside a frame, attached to a backing board with tape partially holding it around some edges. The paper was so thin and weak that tears had started to appear along many of the original fold lines whilst large areas were breaking around the edges. It was important to remove the letter from the backing for several reasons; the backing board itself, made from poor quality board was likely to be causing damage to the paper. Unless they are archival quality, backing boards and framing materials are often made of very poor quality materials with high levels of acidity. As these materials break down they can transfer acidity to materials they are attached to, increasing their deterioration. I also needed to access the document to effectively repair the tears and remove the adhesive tape.
I was able to successfully remove the letter from the mount using a spatula to ease the tape away from the board surface.
When the board was removed it was possible to clearly see acid transfer which appeared to be coming from the document and transferring onto the backing board, suggesting the paper itself is acidic. This is likely to be due to the ingredients used when the paper was originally made, for example additives such as sizing and fillers or the materials the paper is made from such as wood pulp. The ingredients vary between paper mills and throughout the history of papermaking, for example Lignin from wood pulp is extremely acidic and is generally found in modern papers such as newsprint. This is what makes newsprint go yellow and brittle so quickly.
After removing the document from the backing a new area of writing was discovered where the letter had in fact continued overleaf. The archivist was then able to add this to the existing transcription.
Once the letter was separated from the backing board I could then remove the adhesive tape. This task of removing tape is always daunting for a conservator as different adhesives react completely differently to different types of removal. Sometimes it can take a long time to find a method that softens or releases the adhesive so that the tape can be removed.
On this occasion I found that applying moisture directly onto the tape was enough to release the adhesive. However, a thick piece of brown adhesive tape down the left side of the letter was so stubborn that after removing a small amount I decided it would be better to leave that particular piece of tape on rather than risking damage to the already fragile paper surface.
Once the tape had been removed I surface cleaned the document being careful to avoid any weak areas. I was then able to move on to repairing and stabilising.
Tears on paper documents are generally repaired by adhering small pieces of Japanese tissue to the reverse.
The tissue I used for the letter is only 5 gsm, so it is extremely thin and light- but strong enough to stabilise the tears and weak areas without distracting from the letter itself.
Two areas of the document had large gaps that although supported on the back with the Japanese tissue repairs, needed to be infilled with a paper of a similar thickness to the letter itself, to prepare the document for mounting. In the conservation of archival documents (as opposed to artworks) it is particularly important that repairs such as this are visible additions, clearly seen as modern repairs and not blended to make them invisible. This ensures that future historians and researchers are aware of the difference between the original document and any conservation work that has been done.
Creating an Inlay
In paper conservation an inlay is a piece of paper that is attached around the outside of the document to protect it and prevent further damage to fragile edges. This is achieved by tracing around the edge of the document using a needle and then removing the inner piece of inlay paper to create a paper frame. The inlay paper is attached to the document by thin strips of Japanese tissue adhered along the gap between the two. The inlay protects the original document whilst still retaining full visual access to it. It also means that the document can be attached inside the mount by putting hinges on the inlay paper rather than directly on the document itself and that the letter can be fully displayed in the aperture of the window mount without falling out through the middle.
Having reached the milestone of 10 years in my current place of work, I have been reflecting on the development of my career. I think my greatest fear as a conservator is stagnation: for my work to have lost its vibrancy and draw, for my relationship with my career to have become stale.
Thankfully, even after a decade I still find daily challenges and opportunities to develop and thrive within the sector. The importance of Continuing Professional Development (CPD) is emphasised within the conservation arena; viewed as integral to the maintenance of professional standards by organisations such as ICON, the Institute of Conservation.
Being an accredited conservator (ACR), maintaining CPD is essential to retaining my accredited status.
The CPD format encouraged by ICON allows conservators to reflect on where they have come from, focusing their aims for the future. Through a candid analysis of the strengths and weaknesses within both my team and my own armoury I was able to identify a need to improve specialist knowledge of the care of natural history specimens.
The generous award of a True Vue professional development grant allowed me to secure a place on an intensive 3 day course focusing on the care and conservation of vertebrate taxidermy specimens with Simon Moore, a subject specialist with 50 years experience.
The 3 day course kindly hosted by Reading Museum allowed experience of a broad range of materials and techniques. From the art of opening historic glazed cases, without which you’d never access the specimens; to the cleaning of feathers, repair and replication of birds toes and the creation of hair plugs for a balding otter!
The course created a relaxed welcoming environment in which I felt able to voice my previous anxieties about tackling such materials from the risk of shattering historic glass to fears of using the wrong materials and my work ending in a terrible taxidermy publication!
The natural history collection at Reading Museum is extensive and allowed course attendees the irreplaceable opportunity to put theory into practice.
Corrosion that appears on metal objects is a chemical reaction where the metal is trying to return to its natural mineral state. This often appears as green deposits on copper and red/brown deposits on iron. The main cause of corrosion on metals is a humid environment.
How do you remove corrosion?
Some corrosion is good! If your metal object has a thin dark layer on the surface this may be acting as a protective barrier from further break down of the surface. This is called patination or tarnish.
We would recommend you avoid trying to remove heavy build-up of corrosion yourself. This often needs to be done under a microscope in controlled conditions. Excessive use of polishes and chemicals (I’m including Cola and Ketchup in this!) could remove original surface so that details and decoration are lost. For example, you would no longer be able to identify the date of a coin if the surface was abraded and removed. It can also cause the metal to thin and wear down silver plating. Chat to a conservator if you are concerned about the corrosion build up on your object or want to find the most suitable cleaning regime.
How do I care for the object in the future?
One of the most damaging things to metals is the oils and acids from our fingers, which can etch in to the surface of the metal. We would recommend always wearing cotton, nitrile or latex clothes when handling metal objects. This will also reduce marks and therefore the need for cleaning.
Giving the metal object a dust with a soft micro-fibre cloth or soft hog or pony hair brush will help prevent build-up of dust and dirt. Buffing or coating the surface with wax should rarely be necessary and should only ever be attempted after removing dust and dirt. Depending on the object and environmental conditions a wax or lacquer may be applied to protect the surface from humidity and prevent future corrosion development.
Store in an environment with a low humidity and pack using inert materials such as foam or acid free envelopes. A hoard of coins recently in conservation was packaged in individual acid free paper envelopes, sealed in a Polypropylene plastic box (recycling number ‘5 PP’) to provide a controlled environment and a sachet of silica gel to reduce humidity.
So, remember, avoid the cola and gently brush your objects to maintain a healthy patination!
