   HOW THE WHITE AND BLACK “FUMATE” ARE PRODUCED
   
   Vatican City, 12 March 2013 (VIS) – Beginning with the Conclave in   
   2005, in order to better distinguish the colour of the “fumate”   
   (smoke signalling the election or non-election of a pontiff), a secondary   
   apparatus is used to   
   generate the smoke in addition to the traditional stove in which the Cardinal   
   electors' ballots are burned. This device stands next to the ballot-burning   
   stove and has a compartment where, according to the results of the vote,   
   different coloured-smoke   
   generating compounds can be mixed. The result is requested by means of an   
   electronic control panel and lasts for several minutes while the ballots are   
   burning in the other stove.
   
   For a black “fumata” the chemical compound is made of potassium   
   perchlorate, anthracene, and sulphur. The white “fumata” is a   
   mixture of potassium chlorate, lactose, and rosin. The rosin is a natural   
   amber resin obtained from   
   conifers. Prior to 2005 the black smoke was obtained by using smoke black or   
   pitch and the white smoke by using wet straw.
   
   The stove-pipes of the stove and the smoke-producing device join up and   
   exit the roof of the Sistine Chapel as one pipe leading to the chimney   
   installed on the ridge of the roof, which is visible from St. Peter's Square.   
   To improve the airflow the   
   pipe is pre-heated by electrical resistance and it also has a backup fan.
