Alchemy is a burn event operated according to the 10 Principles of Burning Man held annually in the early fall. Alchemy was first held in 2007 and grew quickly to become the largest regional burn in the United States and second largest in the world in 2012. In 2013, the event cap was lowered by approximately 1,000. However the 2014 cap is set at 3,200 participants. Those who have tickets for the 2014 are suggested to volunteer for this event since the entire event is run by volunteers.
