In brief
When a new pope is elected, smoke from the Sistine Chapel's chimney announces the decision—a tradition that combines chemistry, engineering, and deep symbolism.
When the Vatican prepares to elect a new pope, all eyes turn to a small chimney atop the Sistine Chapel, where smoke signals communicate the momentous news. If the smoke is black, it means no pope has been elected; white smoke signals success, accompanied by the declaration "Habemus Papam" – we have a pope. This age-old practice, which captivates millions worldwide, is rooted in history but requires meticulous planning.Behind the scenes, experts from various fields collaborate to ensure the smoke's exact message. The Vatican has added custom fireworks-like chemical processes, a carefully constructed chimney, and specialized equipment to facilitate this sacred communication. With the funeral of Pope Francis concluded, the papal conclave is set for May 7 at St. Peter's Basilica, where cardinals will gather to vote on the new leader of the Catholic Church.The smoke announcement tradition dates back to the 15th century, originally aimed at ensuring a transparent election. Today, centuries of history converge with the necessity for clear communication, as intricate engineering ensures smooth operations. Two stoves are set up specifically for the conclave; one burns the paper ballots, while the other creates the smoke signals, moved through a discreet chimney. Vatican firefighters stand by, ensuring everything works as planned, as any misstep could turn into an international event.To create the perfect smoke, experts utilize specific chemical compounds—one mix for black smoke and another for white—to prevent any ambiguity. While ideas for modernization have emerged, the Vatican opts to stick to its tradition, which ties the process back to ancient rituals and teachings. As the world waits for the next pope, the ritual of smoke continues to connect a global audience to a rich legacy.
