The History Behind the Papal Smoke, Explained
Black smoke means the cardinals did not come to a two-thirds consensus, while white smoke means a new pope has been elected
Some chemical additives have been added to the burnt ballots to avoid any possible confusion over the smoke's color
After every vote during the conclave to pick Pope Francis's successor, either black or white smoke will fill the sky above the Vatican.
Although the voting takes place behind closed doors and is notoriously secretive, this longstanding tradition is a way to inform the public of the outcome of the vote. Black smoke (fumata nera) means the voting cardinals did not come to a two-thirds consensus. White smoke (fumata bianca), on the other hand, means a new pope has been elected.

The smoke tradition is not nearly as old as the papacy itself or even the Sistine Chapel, where the voting takes place. The special chimney that gets temporarily installed every conclave dates back to the 1700s, according to History.com — and as the BBC points out, since the Sistine Chapel is a work of art itself, installation can be a delicate process.
"This is such a precise process because if one thing goes wrong, it's not just a technical failure - it becomes an international incident," structural engineer Kevin Farlam told the outlet.

Burning ballots after they've been counted, which truly ensures their secrecy, dates back to the 1400s, according to History.com, although historian Frederic J. Baumgartner told the outlet that the tradition likely began way earlier.
The Irish News reported that the use of white smoke only came about during the 1914 conclave, which ended up choosing Pope Benedict XV. The use of black smoke, however, can be traced to the 1800s.

However, as conclaves came and went, it became difficult to control the color of the smoke.
In 2005, after previous conclaves ended up releasing gray-looking smoke and confusing onlookers, the Vatican adopted a new strategy. The smoke still comes from the burning of ballots, but it is now also combined with chemical additives from another stove.
That same year, which resulted in the election of Pope Benedict XVI, the Vatican also began ringing bells as confirmation that a new pope has been chosen.
The BBC reported that black smoke is created by a mixture of potassium perchlorate, anthracene and sulphur, while white smoke is created with potassium chlorate, lactose and rosin.

100 days of Pope Leo XIV: A calm papacy that avoids polemics is coming into focus
Leo seems eager above all to avoid polemics or making the papacy about himself, and wants instead to focus on Christ and peace. Advertisement That seems exactly what many Catholic faithful want, and may respond to what today's church needs. 'He's been very direct and forthright … but he's not doing spontaneous press hits,' said Kevin Hughes, chair of theology and religious studies at Leo's alma mater, Villanova University. Leo has a different style than Francis, and that has brought relief to many, Hughes said in a telephone interview. 'Even those who really loved Pope Francis always kind of held their breath a little bit: You didn't know what was going to come out next or what he was going to do,' Hughes said. Advertisement Leo has certainly gone out of his way in his first 100 days to try to heal divisions that deepened during Francis' pontificate, offering messages of unity and avoiding controversy at almost every turn. Even his signature issue — confronting the promise and peril posed by artificial intelligence — is something that conservatives and progressives alike agree is important. Francis' emphasis on caring for the environment and migrants often alienated conservatives. Closer to home, Leo offered the Holy See bureaucracy a reassuring, conciliatory message after Francis' occasionally authoritarian style rubbed some in the Vatican the wrong way. 'Popes come and go, but the Curia remains,' Leo told Vatican officials soon after his May 8 election. Leo, though, has cemented Francis' environmental legacy by celebrating the first-ever ecologically inspired Mass. He has furthered that legacy by giving the go-ahead for the Vatican to turn a 430-hectare (1,000-acre) field north of Rome into a vast solar farm that should generate enough electricity to meet Vatican City's needs and turn it into the world's first carbon-neutral state. He has fine-tuned financial transparency regulations that Francis initiated, tweaked some other decrees to give them consistency and logic, and confirmed Francis in deciding to declare one of the 19th century's most influential saints, John Henry Newman, a 'doctor' of the church. But he hasn't granted any sit-down, tell-all interviews or made headline-grabbing, off-the-cuff comments like his predecessor did. He hasn't made any major appointments, including to fill his old job, or taken any big trips. In marking the 80th anniversary of the U.S. atomic bombings on Hiroshima and Nagasaki last week, he had a chance to match Francis' novel declaration that the mere possession of nuclear weapons was 'immoral.' But he didn't. Advertisement Compared to President Donald Trump, the other American world leader who took office in 2025 with a flurry of Sharpie-penned executive decrees, Leo has eased into his new job slowly, deliberately and quietly, almost trying not to draw attention to himself. At 69, he seems to know that he has time on his side, and that after Francis' revolutionary papacy, the church might need a bit of a breather. One Vatican official who knows Leo said he expects his papacy will have the effect of a 'calming rain' on the church. Maria Isabel Ibarcena Cuarite, a Peruvian member of a Catholic charismatic group, said it was precisely Leo's quiet emphasis on church traditions, its sacraments and love of Christ, that drew her and upward of 1 million young people to Rome for a special Jubilee week this month. Ibarcena said Francis had confused young people like herself with his outreach to LGBTQ+ Catholics and approval of blessings for same-sex couples. Such gestures went beyond what a pope was supposed to do and what the church taught, she thought. Leo, she said, has emphasized that marriage is a sacrament between men and woman. 'Francis was ambiguous, but he is firm,' she said. From his very first appearance on the loggia of St. Peter's Basilica, Leo has insisted he is first and foremost a 'son of St. Augustine. ' It was a reference to the fifth century theological and devotional giant of early Christianity, St. Augustine of Hippo, who inspired the 13th century religious Augustinian order as a community of 'mendicant' friars. Advertisement Like the other big mendicant orders of the early church — the Franciscans, Dominicans and Carmelites — the Augustinians spread across Christian Europe over the centuries. Today, Augustinian spirituality is rooted in a deep interior life of prayer, living in community, and journeying together in search of truth in God. In nearly every speech or homily since his May 8 election, Leo has cited Augustine in one way or another. 'I see a kind of Augustinian flavor in the way that he's presenting all these things,' said Hughes, the theology professor who is an Augustine scholar. Leo joined the Augustinians after graduating from Augustinian-run Villanova, outside Philadelphia, and was twice elected its prior general. He has visited the Augustinian headquarters outside St. Peter's a few times since his election, and some wonder if he will invite some brothers to live with him in the Apostolic Palace to recreate the spirit of Augustinian community life there. Leo is also very much a product of the Francis papacy. Francis named Prevost bishop of Chiclayo, Peru, in 2014 and then moved him to head one of the most important Vatican jobs in 2023 — vetting bishop nominations. In retrospect, it seems Francis had his eye on Prevost as a possible successor. Given Francis' stump speech before the 2013 conclave that elected him pope, the then-Cardinal Jorge Mario Bergoglio essentially described Prevost in identifying the church's mission today: He said the church was 'called to go outside of itself and go to the peripheries, not just geographic but also the existential peripheries.' Prevost, who hails from Chicago, spent his adult life as a missionary in Peru, eventually becoming bishop of Chiclayo. Advertisement 'He is the incarnation of the 'unity of difference,' because he comes from the center, but he lives in the peripheries,' said Emilce Cuda, secretary of the Pontifical Commission for Latin America. Cuda said during a recent conference hosted by Georgetown University that Leo encapsulated in 'word and gesture' the type of missionary church Francis promoted. That said, for all Leo owes to Bergoglio, the two didn't necessarily get along. Prevost has recounted that at one point when he was the Augustinian superior, the then-archbishop of Buenos Aires expressed interest in assigning an Augustinian priest to a specific job in his archdiocese. 'And I, as prior general, said 'I understand, Your Eminence, but he's got to do something else' and so I transferred him somewhere else,' Prevost told parishioners in his home state of Illinois in 2024. Prevost said he 'naively' thought the Francis wouldn't remember him after his 2013 election, and that regardless 'he'll never appoint me bishop' due to the disagreement. Bergoglio not only made him bishop, he laid the groundwork for Prevost to succeed him as pope, the first North American pope following the first South American.

100 days of Pope Leo XIV: Calm papacy that avoids polemics is coming into focus
VATICAN CITY — When Pope Leo XIV surprised tens of thousands of young people at a recent Holy Year celebration with an impromptu popemobile romp around St. Peter's Square, it almost seemed as if some of the informal spontaneity that characterized Pope Francis' 12-year papacy had returned to the Vatican. But the message Leo delivered that night was all his own: In seamless English, Spanish and Italian, Leo told the young people that they were the 'salt of the Earth, the light of the world.' He urged them to spread their hope, faith in Christ and their cries of peace wherever they go. As Robert Prevost marks his 100th day as Pope Leo this weekend, the contours of his pontificate have begun to come into relief, primarily where he shows continuity with Francis and where he signals change. Perhaps the biggest takeaway is that after 12 sometimes turbulent years under Francis, a certain calm and reserve have returned to the papacy.
