After the ballots are pierced, they are burned in a cylindrical stove at the end of the voting session. Black smoke from the Sistine Chapel chimney means no decision; white smoke signals the cardinals have chosen a pope and that he has accepted.

Voting will take place in the Sistine Chapel, with ballots continuing in succession until any candidate secures two-thirds of the available votes. If no clear choice has emerged after three days, balloting is suspended for 24 hours to allow cardinal electors time to reflect.
