The Cauldron designed by londoner Thomas Heatherwick, consists of 205 copper 'petals', one for each competing nation or territory. They were brought into the stadium by each team as part of the athletes’ procession then attached to long pipes in a ring at the centre of the arena.
Seven young British athletes who lit the London 2012 Games cauldron were each nominated by UK Olympic champions. The seven teenagers each lit a single tiny flame from torches to seven of the petals then the flames spread from one petal to the next. Once all the petals were ablaze the pipes rose them upwards to combine as one.
The petals were inscribed with each delegation's name and 'XXX Olympiad London 2012'. After being ignited they rose on long stems to converge and form a cauldron signifying unity and peace.
The Olympic Torch designed by Hackney studio BarberOsgerby was unveiled last year and has been touring the UK since 19 May as part of the Olympic relay but the design of Heatherwick’s cauldron was a closely guarded secret until yesterday.
Thomas Heatherwick has had a solo exhibition at London's V&A Museum as part of the London 2012 Festival. An exhibit about the Olympic Cauldron will be added to Heatherwick’s ongoing exhibition at the V&A museum from today.
