Conserving the pottery, terracotta and tablets from Ur

Duygu Camurcuoglu, conservator, Ur Project, British Museum

My job is to assess the condition of the objects from Ur being studied as part of the Ur digitisation project, conserve them if necessary, and guide the project team on handling and safe storage of the objects before/during photography and further digitisation work. I joined the project in August 2013 to lead the conservation and my first responsibility was to assess and conserve the terracotta objects and the clay tablets with ancient cuneiform inscriptions on study loan from Iraq.

There are over a thousand terracotta objects from Ur in the British Museum’s collection, primarily reliefs, figurines and models. Although some are skilfully modelled, the majority are rather crude and mass-produced in moulds. My initial task was to assess each one, selecting those that needed treatment and completing the work before they could be handled and photographed. In the image above, you can see me assessing the condition of one of the important objects from Ur, the fired clay mask of Humbaba, a fearsome monster slain by Gilgamesh in Mesopotamian literature. During the process, colleagues from ceramics and glass conservation joined me to complete the assessment work on the objects, while I undertook the actual conservation treatments.

Following the terracotta objects, I assessed the condition of the pottery from Ur. This large collection comprises over a thousand ceramic vessels in various sizes, shapes, colours and fabrics. This was a huge challenge! Every day, my colleague Gareth Brereton and I went to one of British Museum’s storage areas where the pottery from Ur is housed. We set up a small working area in this room for object assessments, photography and registration. There were a large number of cupboards to go through, so Gareth and I worked almost every morning together, assessing the condition of each pot so that Gareth could handle, photograph and register them. We had plenty of exercise going up and down the ladder each morning as some of the objects were stored very high up in the shelves.

Most terracotta objects and ceramic vessels from Ur are in good condition. They sometimes require conservation work, since they have unstable fragments, flakes or cracks on their surfaces. This is very normal due to the age of the objects, most are which are about 4,000 years old. It is crucial that the necessary treatments are undertaken. When unstable objects are not treated using proper conservation techniques and materials, further problems may occur during storage and handling, such as loss of surfaces and decoration, cracks, breakage of fragments that can make it difficult to study and learn more from the objects.

I identify any cracks and/or unstable flakes on the surface of the vessels before stabilising them using conservation grade materials. I often use a fine brush or a micropipette for this work. Once the treatment is completed, I enter all my treatment records onto the British Museum’s curatorial database, Merlin, so that the information is accessible across the Museum and the world via the collection online.

I have also been assessing and undertaking conservation on the cuneiform tablets from Ur. It is particularly important to prevent the loss of surfaces from tablets, because that would mean loss of the text.

Apart from undertaking remedial ‘hands on’ work with objects, I am also responsible from supporting the Ur team when they have any questions about handling the objects safely, as some are very fragile. I also monitor the environmental conditions in the Ur project lab and storage cupboards, using digital sensors which we place in different areas. This is important because fluctuating temperature and relative humidity can severely damage archaeological objects. For example, soluble salts in the ceramic and clay fabrics can react very quickly with the fluctuating conditions, resulting in delamination and loss of object surfaces, which can contain elaborate decorations, pigments and reliefs.

When I have completed the conservation work on the pottery and the cuneiform tablets, I will move on to the conservation of other types of objects and materials from Ur, in order to prepare them for digitisation and further study. I am looking forward to the challenge!

I am responsible for managing the digitisation of objects and archives for the Ur Project, a dynamic new collaboration between the British Museum and Penn Museum made possible with the lead support of the Leon Levy Foundation. The project takes the successful cooperation of the two organisations of the 1920s and 1930s at Ur into the 21st century, digitally reunifying the remarkable finds from that site in a state-of-the-art website. We are photographing and documenting all the finds from Ur in our collections, from small pieces of broken pots to ancient cuneiform texts and exquisite gold jewellery. We are also digitising the original excavation photographs, archives, plans and other documents. Our resource will bring together these varied sources of information for the first time and make them available in an online database that will preserve the complete finds and records in digital formats for posterity.

Ur was an important city throughout Mesopotamian history. The excavations, led by Sir Leonard Woolley and jointly sponsored by the British Museum and the Penn Museum, uncovered its famous ziggurat complex, areas of densely packed private houses, and the spectacular Royal Graves with rich inventories of gold and evidence of human sacrifice. These unique finds provide crucial information about third-millennium society, as well as the warfare, music, food, drink, and customs of the period. We can also learn much about the people that lived and died in this city through the study of the cuneiform tablets excavated at the site. There are about 10,000 of these ancient texts from Ur in the partner museums’ collections.

By 1922–34 Woolley had developed his methods with an increased emphasis on recording. Thus, the vast scale of the finds he recovered – numbering into the tens of thousands – are contextualised by an abundance of documentation. The British Museum houses the core part of this documentation, such as the original glass-plate negative photographs, and the excavation diaries. We are digitising, indexing, and cross-referencing these indispensable resources.

The most exiting aspect of the project is the rare opportunity it provides to reunify dispersed information. Not only will the collections from the three museums (the British Museum, Penn Museum and the Iraq Museum) be integrated, but also the different categories of object brought together in one virtual space, and, crucially, barriers between object data and archives will be broken down.

Our website will present for the first time an authoritative set of high resolution images of the entirety of the finds, integrated with all field notes, catalogue records, photos, reports, maps, letters and publications. Importantly, data are recorded in a format that allows them to be fully indexable and extractable, enabling people to create their own datasets and make comparisons with their own research. This approach will also allow us to re-establish lost object identifications and crucial findspot information. We will relate internal references between notes, letters, publications and catalogues, connect artefacts to their findspots on maps, and link wherever possible to other resources with the goal of enabling researchers to analyse the site in exciting new ways. All data are thoroughly cross-referenced, facilitating the study of artefacts all the way from excavation context to current display.

Activity is currently underway at the British Museum and at Penn Museum. We hope soon to be joined by our colleagues at the Iraq Museum. Our work feeds into the shared project website, as well as each museum’s own collection database. Our web resource will eliminate traditional barriers between institutions, enabling people to focus on the material from Ur as a single corpus, disregarding the objects’ current locations. We hope that our approach will inspire the digitisation of other similarly dispersed collections.

The project staff bring expertise in archives, photography, programming, conservation, Assyriology and archaeology. This range of skills reflects the diversity of information being collated, and indicates the great potential for research our resource provides. I look forward to bringing you future updates about the project as it progresses.

This is an exquisitely decorated purse lid from the Anglo-Saxon burial at #SuttonHoo, which was brought to the world's attention #onthisday in 1939. In this object the quality of craftsmanship can really be appreciated. The lid is only 19cm in length but it must have been incredibly valuable. The outstanding nature of the finds at Sutton Hoo points to this being the burial of a leading figure in East Anglia, possibly a king. The landowner Mrs Edith Petty donated the discovery to the British Museum in 1939.
#SuttonHoo #Gold #Archaeology #AngloSaxon Today we’re celebrating the unearthing of the beautiful Anglo-Saxon objects from #SuttonHoo, which were found #onthisday in 1939. Arguably the most iconic of all the objects, this helmet was an astonishingly rare find. Meticulous reconstruction has allowed us to see its full shape and some of the complexity of the fine detailing after it was damaged in the burial chamber. The gold areas of the helmet reveal a dragon or bird-like figure – the moustache forms the tail, the nose forms the body and the eyebrows form the wings, with a head just above. Another animal head can be seen facing down towards this.
#SuttonHoo #AngloSaxon #Gold #Helmet #Archaeology #onthisday in 1939, just before the outbreak of the Second World War, archaeologists discovered the treasures of #SuttonHoo. It was one of the most important historical discoveries of the 20th century, and contained a wealth of Anglo-Saxon objects which greatly enhanced the understanding of the early medieval period. One of the most significant things to be found was an undisturbed ship-burial, the excavation of which can be seen in this photo. The 27-metre-long impression the ship left in the earth is highly detailed and was painstakingly recorded. The centre of the ship contained a burial chamber housing some spectacular objects – we’ll be sharing some highlights today.
#SuttonHoo #AngloSaxon  #archaeology #archive #blackandwhite This photograph shows a mountainside in #Angola featuring large engravings which may be thousands of years old. This rock art is found at Tchitundu-Hulu Mulume, one of a group of four rock art sites located in the south-west corner of Angola, by the edge of the Namib desert. The area is a semi-arid plain characterised by the presence of several inselbergs (isolated hills rising from the plain). Of the four sites, Tchitundu-Hulu Mulume is the largest, located at the top of an inselberg, 726 metres in height. There are large engravings on the slopes of the outcrop, most of them consisting of simple or concentric circles and solar-like images.

Our #AfricanRockArt image project team have now completed cataloguing 19,000 rock art images from Northern, Eastern and Southern Africa, and will be completing work on sites from Southern African countries in the final phase of the project. Follow the link in our bio to find out more about our African #rockart image project and the incredible images being catalogued.

Working with digital photographs has allowed the Museum to use new technologies to study, preserve, and enhance the rock art, while leaving it in situ.

As part of the cataloguing process, the project team document each photograph, identifying what is depicted. Sometimes images are faded or unclear. Using photo manipulation software, images can be run through a process that enhances the pigments. By focusing on different sets of colours, we can now see the layers that were previously hidden to the naked eye.

This painted panel, from Kondoa District in #Tanzania, shows the white outline of an elephant’s head at the right, along with some figures in red that it is possible to highlight with digital enhancement.

Tanzania contains some of the densest concentrations of rock art in East Africa, mainly paintings found in the Kondoa area and adjoining Lake Eyasi basin. The oldest of these paintings are attributed to hunter-gatherers and may be 10,000 years old.

Follow the link in our bio to learn more about the project and see stunning #rockart from Africa. This week we’re highlighting the work of our #AfricanRockArt image project. The project team are now in the third year of cataloguing, and have uploaded around 19,000 digital photographs of rock art from all over #Africa to the Museum’s collection online database.

This photograph shows an engraving of a large, almost life-sized elephant, found on the Messak Plateau in #Libya. This region is home to tens of thousands of depictions, and is best known for larger-than-life-size engravings of animals such as elephants, rhino and a now extinct species of buffalo. This work of rock art most likely comes from the Early Hunter Period and could be up to 12,000 years old.
