Abstract

There is provided a method of manufacturing a combustible heat source having a barrier, the method including providing a mold defining a cavity; placing a particulate component in the mold cavity; placing a laminar component, adjacent the mold, to cover the cavity opening; and compressing the particulate component to form the combustible heat source, wherein, during the compression step, the barrier is formed by punching the laminar component using a punch and the mold, the punch acting on the barrier to compress the particulate component and affix the barrier to the combustible heat source.
