"The design of the mini cauldron displays sculpted blades formed in the shape of a bigger torch. The opening on the sides allows for ventilation and a peek at the flames, and the CRA-Carlo Ratti Associati team says that the arrangement relies on the Venturi effect, drawing in more air to keep the combustion going. The team adds that the system can operate for up to negative 20 degrees Celsius and other extreme conditions."
"For the Milano Cortina 2026 relay, CRA-Carlo Ratti Associati designs a mobile mini cauldron that casts the flame into a vertical vortex. Developed for selected cities during the Games, it accompanies the torch relay in around 80 public events. Visitors to the Milano Cortina 2026 may see the mini cauldron by Carlo Ratti in selected cities between February 6th and 22nd for the Olympic Winter Games and March 6th and 15th for the Paralympic Winter Games."
"The material used to create the mini cauldron by CRA-Carlo Ratti Associati shares the same PVD and metallic blue finish as the torch, which the team also designed. For the torch, the firm adds a burner that runs on bio-LPG, which is made from renewable raw materials and mainly waste resources, including used cooking oil, animal fats, and residues from the agricultural industry."
CRA-Carlo Ratti Associati designed a mobile mini cauldron for the Milano Cortina 2026 relay that projects the flame into a vertical vortex and features sculpted blades shaped like a larger torch. Side openings provide ventilation and visibility of the flame, while the arrangement leverages the Venturi effect to draw in air and sustain combustion. The system can operate in temperatures down to minus 20 degrees Celsius and in other extreme conditions. The cauldron and torches share a PVD metallic blue, iridescent finish. Torches include a bio-LPG burner and a polymeric insert using 60 percent bio-naphtha; torch bodies use recycled aluminum and brass alloy.
