Cauldrons on the move

As I wasn’t at the excavation of the Chiseldon cauldrons it was difficult to imagine that the nine or so blocks of soil sitting in plastic crates and wrapped in plaster bandages really contained Iron Age cauldrons. But a few weeks ago when Alex and I visited the Museum’s off-site store, I knelt down and looked at the closest crate and spotted the edges of metal sheet and part of an iron handle sticking out of the soil.

It’s at moments like this that you start to think about the step by step process of conserving the object to bring it back to life (and also quickly calculate how many hours it might take… literally hundreds).

But before we could start work we had to move the cauldrons from storage to the Museum itself.

The Museum’s off-site store is vast with hundreds of crates and many rows of racking which all hold evidence of Britain’s past. While it was easy for us to jump on the tube to get to the store, transporting the cauldrons was a little bit trickier.

We picked two of them – discovered next to each other in the burial pit, and corroded together – and packed them safely in big boxes. It’s always nerve-racking transporting fragile objects, so to protect them we surrounded them with rolled-up tissue paper, foam and bubble wrap.

Once safely at the Museum we moved the crates to the metals conservation lab and carefully unpacked the cauldrons.

The first step is to record the soil blocks and fragments of cauldrons by taking pictures, making detailed drawings and examining the surface through a microscope. In preparation for the next stage, when conservation really begins, you can then begin to start removing some of the soil with small hand tools and brushes.

Digging up – and preserving – the Iron Age

Alexandra Baldwin, British Museum

Alexandra Baldwin excavating the cauldrons

Five years ago I, and my colleague Simon Dove in the department of Conservation and Scientific Research at the British Museum, joined a team from Wessex Archaeology in a field in Wiltshire to excavate what we thought were three small bowls. Two weeks later, in baking sun and torrential rain, we had lifted 10 – or 12 – rather large cauldrons.

Brilliant! 10 Cauldrons! Being extremely rare, this was an exciting find.

One would have been fantastic. Three would have been amazing. But 10-12, on the other hand, was a huge challenge. First, we had to excavate them. Then we had to store them and finally conserve them so we can learn from them and perhaps even put them on display.

With such a huge find, and with the conservation project alone estimated to take two of us two years, Jody Joy, British Museum curator of Iron Age Britain, and I decided to apply for funding to study the cauldrons properly and conserve them so that we could understand their wider significance and give them the attention they deserve.

Now we have the funding, work has started and over the next two years myself and a colleague, and Jody, along with scientists and other British Museum staff, will be unravelling the evidence of life in the Iron Age the cauldrons can provide us with.

In the coming months I’ll be writing regular posts – as will Jody, and my colleague in the conservation team Jamie Hood – documenting the journey through the project and describing what goes on behind the scenes at the British Museum, revealing discoveries as we find them… and not to mention the challenges we face.

It's #NAIDOC2015 – a week celebrating the history and culture of Aboriginal and Torres Strait Islander peoples. We’ll be sharing objects each day this week from our #IndigenousAustralia exhibition.
This masterpiece of Indigenous art is called 'Yumari' and is on loan from the National Museum of Australia. It was created by the artist Uta Uta Tjangala in 1981 and is a highlight of the exhibition. Tjangala was one of the artists who initiated the translation of sand sculptures and body painting onto canvas at Papunya in 1971, making him a pioneer of contemporary Australian art. This iconic work now features on the Australian passport.

This is one of a collection of photographs taken by the photographer Frederick York of Notting Hill, London in 1875.
#tbt #throwback #archives #mummies We’re delighted to announce our first exhibition of the autumn ‘Drawing in silver and gold: Leonardo to Jasper Johns’, which opens 10 September.
This exhibition will feature around 100 of the best examples of #metalpoint spanning six centuries. Metalpoint is a challenging drawing technique where a metal stylus is used on a roughened preparation, ensuring that a trace of the metal is left on the surface. When mastered it can produce drawings of crystalline clarity and refinement.
This exhibition was organised by the National Gallery of Art, Washington @ngadc in association with the British Museum.
Book your tickets now to see these spectacular works! #art #drawing #Leonardo

Leonardo da Vinci (1452-1519), Bust of a warrior. Silverpoint, on prepared paper, c. 1475-1480. Can you guess the artist behind this work? 
All will be revealed at our special exhibition announcement tomorrow! #metalpoint Tower Bridge opened #onthisday in 1894. Here’s an early print of the iconic landmark.
