Abstract: Described are combustible structures. For example, a combustible structure includes a starter fuel chamber with a starter fuel, an external lighter opening, and an external air opening. The combustible structure includes a conveying fuel chamber adjacent to the starter fuel chamber and including a conveying fuel. The combustible structure includes a partition between the conveying fuel chamber and the starter fuel chamber, the partition including an opening such that combustion in the starter fuel chamber can spread to the conveying fuel chamber through the opening. The combustible structure includes a fuel chamber that includes an artificial fire log and an external vent. The combustible structure includes a retaining structure that provides for ease of transport and holds the artificial fire log in place such that combustion in the conveying fuel chamber spreads to the fuel chamber.
