The pope is elected in the Conclave, composed of all the cardinal electors (now limited to all the cardinals below the age of 80), after the death or resignation of the previous Pope. The Conclave is held in the Sistine Chapel, where all the electors are locked in (Latin cum clave) until the election for which a two-thirds majority is required. The faithful can follow the results of the polls (usually two in the morning and two in the evening, until election) by a chimney-top, visible from St. Peter's Square: in a stove attached to the chimney are burnt the voting papers, and additives make the resulting smoke black (fumata nera) in case of no election, white (fumata bianca) when the new pope is finally elected. The Dean of the Sacred College (Cardinale Decano) will then ask the freshly elected pope to choose his pastoral name, and as soon as the pope is dressed with the white habit, the Senior Cardinal-Deacon (Cardinale Protodiacono) appears on the major balcony of St. Peter's façade to introduce the new pope[2] with the famous Latin sentence
Annuntio vobis gaudium magnum: habemus papam.(I announce to you a great joy: We have a Pope).
