Abstract
A combustible heat source () for a smoking article () comprises carbon and at least one ignition aid, wherein the ignition aid is present in an amount of at least 20 percent by dry weight of the combustible heat source. The combustible heat source () has a first portion and an opposed second portion. At least part () of the combustible heat source () between the first portion and the second portion is wrapped in a combustion resistant wrapper () that is one or both of heat conducting and substantially oxygen impermeable. Upon ignition of the first portion of the combustible heat source (), the second portion of the combustible heat source increases in temperature to a first temperature. During subsequent combustion of the combustible heat source (), the second portion of the combustible heat source () maintains a second temperature lower than the first temperature.
