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.

Vanished beneath the waters of the Mediterranean, the lost cities of Thonis-Heracleion and Canopus lay at the mouth of the Nile. Over the last 20 years, world-renowned archaeologist Franck Goddio and his team have excavated spectacular underwater discoveries using the latest technologies. They will be seen alongside fascinating objects from major Egyptian museums for the first time in the UK in this blockbuster exhibition.

Christoph Gerigk © Franck Goddio/Hilti Foundation We are delighted to announce our first major exhibition on underwater archaeology! Submerged under the sea for over a thousand years, two lost cities of ancient Egypt were recently rediscovered. Their amazing discovery is transforming our understanding of the deep connections between the great ancient civilisations of Egypt and Greece.

Christoph Gerigk © Franck Goddio/Hilti Foundation You can now discover thousands of British Museum objects in partnership with @googleartproject at We’ve asked staff members to highlight their favourites and explain what makes them special. Chris Spring, Curator of Africa Collections, describes why he finds the ‘Throne of weapons’ so powerful. ‘This war memorial celebrates the ordinary people of Mozambique, many of them unarmed, who stood up to a culture of violence. It represents both a human tragedy and a human triumph. The Throne's essential humanity is suggested right away by its anthropomorphic qualities - it has arms, legs, a back and most importantly a face - actually two faces. My first reaction was that these faces are crying in pain, though they could also be seen as smiling faces finally freed from conflict. These anthropomorphic qualities also link it immediately to the arts of Africa, in which non-figurative objects such as chairs, stools, weapons, pots etc are seen as - and described as - human beings. The Throne has toured the world, taking its message of peace to schools, churches, shopping centres and even prisons – and of course, to museums and galleries.’ #MuseumOfTheWorld We’re celebrating our partnership with @googleartproject, and have asked curators to tell us about their favourite objects. Hugo Chapman, Keeper of Prints and Drawings, explains why he chose this chalk drawing by Michelangelo. ‘One of the things I love about drawings is the way they sometimes allow a glimpse into the private, behind the scenes world of an artist, one unseen in finished works in paint or stone. An example of that is a red chalk drawing by Michelangelo of grotesque heads in red chalk that reveal that the Florentine Renaissance artist had a lively, if caustic, sense of humour. The three heads were probably drawn to amuse but at the same instruct his pupils, as the three studies show how slight changes can radically alter the reading of an image with the character and mood of each figure (paranoid anxiety; vacuous joy; and depressive gloom) signalled by the position and erectness of their donkey-like ears.  I wish my ears were as expressive.’ Discover many more incredible works of art in the Google Cultural Institute at

#Michelangelo #art To celebrate our partnership with @googleartproject, we’ve asked members of British Museum staff to highlight their favourite objects and explain what makes them special. Jill Cook, Deputy Keeper of Britain, Europe & Prehistory, chose this stone chopping tool from an early human campsite in Olduvai Gorge, Tanzania. ‘Holding this 2 million year old African tool in my hand I am reminded that whatever differences exist between people now, we are united by our common origin in Africa. The discovery of this piece by Louis Leakey in 1931 began to change our understanding of what makes us human. It illustrates the beginning of a transition from an ancestral ape that walked upright on two legs within the confines of a limited ecological niche to humans with more complex brains capable of changing and eventually dominating the world around us by making tools and weapons. This chopping tool is one of the seeds from which all human cultures and societies have grown.’ Discover the stories of thousands of objects in the Google Cultural Institute at
