2012 Summer Olympics and Paralympics cauldron

British designer Thomas Heatherwick was chosen by Danny Boyle to design the cauldron for the 2012 London Summer Olympics and Paralympic Games (the same design would serve both). Heatherwick was a highly regarded designer, responsible for the first prize-winning "Seed Cathedral" at the 2010 Shanghai Expo, and the New Routemaster bus introduced in London in February 2012; Boyle was an admirer of his B of the Bang sculpture in Manchester, saying of it 'I loved it so much; it's a tragedy they took it down in 2009 ... These public sculptures breathe life into you.' The brief was that the cauldron should be something that connected all the nations, with the idea of them each bringing a constituent part of it, and also have a story or narrative. It was to be of a human scale, and to be placed among the people in the stadium rather than towering over it. It was also to be transient, like the coming-together of nations during each Games. Heatherwick said “When Danny Boyle asked us to do this we felt this huge responsibility. We asked people: ‘Which cauldron do you remember?’ And the answer was: none. Our role was to design a 'moment': how could we make this moment manifest in the object? We didn't just want to make a bowl on a stick.” Heatherwick and his team spent two months researching and examining ideas, including a weekend spent looking at all previous Olympic cauldron designs. Another important part of the brief was "Whatever you do, no moving parts". This was due to the failure of the cauldron at the 2010 Winter Olympics at Vancouver, when one of the four moving parts of the cauldron had failed to work. Heatherwick wanted the cauldron to be a focal point, like an altar in a church, The Olympic cauldron comprised 204 separate copper 'petals', and the Paralympic one 164 – one petal from each of the competing nations. , opening out prior to being extinguished ==Production==

Production began in January 2012 in the workshops of Tockwith, near Harrogate-based firm Stage One, a company that also built the two cauldrons for the 2026 Winter Games. Each 3mm thick petal was unique: designed individually using 3D modelling, hand beaten from copper sheeting, and polished by skilled craftsmen. Each was hand-beaten over its own individual MDF former and took eight hours to produce. The petals were inscribed with the name of the competing country and "The XXX Olympiad – London 2012". Three full sets were made: for Olympic and Paralympic cauldrons, with a third for rehearsals and testing. with a variable burn rate. The gas burners were designed by Australian firm FCT Flames based in Adelaide, which specialises in the design, manufacture and operation of ceremonial cauldrons around the world.The firm became a partner of the International Olympic Committee shortly after the 2000 Summer Olympics and became responsible for manufacturing the fuel in which the Olympic flame burns during the relay and in many cases was responsible for the construction and elaboration of the Pyre that burned during the 16 days of the Olympic Games and 12 days of the Paralympic Games in the host city. Strict security and secrecy was paramount during construction and testing. During the project's first phase, which consisted of elaboration, assembly and first tests, the structure was codenamed "Betty", after the dog of the opening ceremony's executive producer Catherine Ugwu. The cauldron was installed in the centre of the arena of Olympic Stadium using a 500-ton crane. This was done during overnight on 10 June 2012, in order to maintain the greatest secret of the opening ceremonies. All the tests and rehearsals were held late at night or in the early morning hours when Olympic airspace restrictions were in place, which stopped civil helicopters or planes from getting a view and take photos During final tests on the eve of the opening ceremony, one of the rods holding the petals became jammed, necessitating overnight repairs; this news was deliberately withheld from Heatherwick. Despite the secrecy, an image of the cauldron was visible in plain sight on the ceremony's tickets. ==Use==

In the Olympics On arriving in London, each national team was presented with an inscribed petal. During the parade at the opening ceremony, each petal was carried by a child accompanying each of the teams as they entered the stadium. Sir Steve Redgrave carried the flame into the stadium and passed it on to one of a team of six young athletes and one young volunteer, each nominated by a famous British Olympian. The torchbearers were (nominator in brackets): Callum Airlie (Shirley Robertson), Jordan Duckitt (Duncan Goodhew), Desirèe Henry (Daley Thompson), Katie Kirk (Mary Peters), Cameron MacRitchie (Steve Redgrave), Aidan Reynolds (Lynn Davies) and Adelle Tracey (Kelly Holmes). The seven stepped forward together to light a petal each. Flames spread radially around the petals, and when all were alight, the stems rose slowly from the floor of the arena and converged to form an upright cauldron with a single, massive flame. The music performed during this part of the ceremony was the specially-commissioned "Caliban's Dream". After the ceremony, the stadium was closed and on the following night the cauldron moved from infield to the end of the stadium formerly occupied by the Olympic Bell. During this move the Olympic flame was kept burning in a small Davy lamp, similar to those used during the torch relay. The cauldron was relit in its new spot by Austin Playfoot, who had carried an Olympic torch in both the 1948 and 2012 Games. For the closing ceremony, the operation of the cauldron was played in reverse: it opened out until flat on the ground, and the flames in the petals extinguished one by one. In the Paralympics For the opening ceremony, the 164 petals were pre-set prior to lighting in a semi-spherical arrangement, and the flames lit from one side of the dome to the other, unlike the spiral of the Olympic cauldron. After the Games Heatherwick had intended that there would not be a large cauldron left after the Games, but instead each petal was to be offered to competing countries as a souvenir. The day after the Olympics opening ceremony, details of the design, including a scale model, were added to the exhibition of Heatherwick's work that was running at the Victoria and Albert Museum in London. A selection of components and mechanisms of the cauldron were put on permanent display at the Museum of London in July 2014, to mark the second anniversary of the Games. ==Reception==

The cauldron received overwhelmingly positive reviews. The London Evening Standard called it "breathtakingly beautiful", while a reviewer for The Daily Telegraph commented that "It dazzles both by its exuberance and inventive dexterity". Creative Review said "From the moment it was lit to its last flicker, Heatherwick Studio's cauldron was an absolute star of the Games. Conceptually brilliant and utterly beautiful it was one of the most successful examples of an ambition among the Games' organisers to reinvent the familiar elements of the Olympics." A reviewer for the Sydney Morning Herald called the cauldron "stunning". ==Controversy==

Siting of cauldron The London stadium had been designed assuming that the cauldron would sit above, as had become customary, on a part of the roof that was specially strengthened. The cauldron was therefore shown on video screens around the Olympic Park. Heatherwick denied that he had been briefed about Atopia's idea, and was adamant that the design was his alone. Danny Boyle also denied knowing about the earlier proposal, while Martin Green, former head of ceremonies at LOCOG, claimed that the idea had emerged from discussions between Boyle, Heatherwick and himself. ==Accolades==

An end of year review chose the cauldron as one of the top five design highlights of 2012, and Heatherwick was voted the ''Architects' Journal'' architecture personality of 2012 by its readers. On 12 March 2013 it was announced that the cauldron had won the Visual Arts category of the 2012 South Bank Sky Arts Awards. The cauldron was shortlisted for the Design Museum's 'Designs of the Year 2013' Awards in the 'Product' category. ==See also==
