Tech Note: The Olympic Torch and Cauldron of the 2012 Summer Games

We are into the second week of the 2012 Summer Olympic Games, and as a friend declared, “the actual Olympics began on Friday, August 3rd  – track and field sporting events”.  OK, that’s his opinion.

I enjoyed the Opening Ceremony that was aired on Friday, July 27, 2012.  There were many high points for this signature event including the active participation of the Queen and her beloved Corgy dogs. I especially liked the completion of the Olympic torch relay and the lighting of the cauldron for this summer’s games. Technical notes regarding the torch and the cauldron are the subject of this post.

Ceremonials

The open burning flame at the games dates back to the Ancient Greeks. Considered to be a divine element, the Greeks maintained perpetual fires in front of their most important temples. This was also true for the sanctuary of Olympia, where the Ancient Olympic Games took place.

For the modern Olympic games, a torch relay precedes the arrival of the flame at its final destination: the Olympic stadium in the host city. When the flame finally arrives at its destination, the final torch bearer runs into the stadium to light the Olympic cauldron. The flame remains lit for the duration of the Games and is extinguished only at the Closing Ceremony. [Ref 1]

In keeping with the ceremonies, the Olympic flame began its journey from Ancient Olympia, Greece on May 10, 2012, exchanged hands with 8,000 torch bearers and passed a number of notable British landmarks before reaching the Olympic stadium in London on July 27, 2012.

2012 Torch Design

According to the London Telegraph [Ref. 2], over 600 proposals were submitted for the prestigious honor of designing the 2012 Olympic torch. The design of Edward Barber and Jay Osgerby was selected and developed in their London studios. A perforated design – with 8,000 holes – provided a transparent appearance while preventing heat from conductively flowing down the handle of the carrier and burning the torch bearer.

According to the designers, “The holes represent the number of people who will take part in the relay.” The torch is also triangular in shape – a first for the Olympics. Previous versions have been cylindrical.  The material for the inner and outer skin is aluminum alloy. It is modern, corrosion and heat resistant, and most importantly, light. Despite its height the torch was designed to be easy to carry for the younger bearers, the whole thing weighing only 800 grams.

Cauldron Design

Similar to the Olympic Torch, the lighting of the cauldron is the apex of the Opening Ceremony. The London designer, Thomas Heatherwick, was given the project of creating the cauldron for the Summer Games.

The 8.5-metre-tall cauldron, which was crafted in a workshop in Harrogate, North Yorkshire, was intended to stand apart from the fiery troughs that had come before it. This special project was given the nickname “Betty”. In addition to being the name of the executive producer’s dog, a project of this magnitude would also contain the secretive nature of the activities and event surrounding the design and lighting ceremonies.

“We were aware cauldrons had been getting bigger, higher, and fatter as each Olympics happened and we felt we shouldn’t try to be even bigger than the last ones,” he said. Betty’s design, Heatherwick added, had also allowed the organizers to stress the diverse but united spirit of the Games. [Ref 3]

2012 Summer Olympics Cauldron – Raising the Petals

In interview with DE-Zeen Magazine [Ref 4], Heatherwick talked about not just designing the cauldron as a thing or an object, but designing for the public moment when more than half the world could be watching.  Unveiled as the climax of the Opening Ceremony, the cauldron comprises 204 copper petals that were carried into the stadium by competing teams and assembled on radiating poles, before being raised in concentric waves to meet as one flame, and form a dandelion of flame. And what a moment that was!

After the games the cauldron will be dismantled and each competing country will take home one of the petals.

Having bloomed so brightly and so perfectly, she will lose her blackened petals as, one by one, they will be dismantled and sent home with each competing country that carried them into the stadium on the night of the Opening Ceremonies.

Replicas of the torch and model-sized cauldrons are selling briskly along with other souvenirs and memorabilia from the 2012 Summer Olympic Games.
