Abstract: A combustible fire block for providing sustained heat output having a combustible fire block body formed from combustible material pressed into a mass and having a base, an intermediate portion and a top; at least one fire propagation path-way formed within the body, said fire propagation pathway running between an opening in the base and an opening in the top and being defined by internal walls of the body the pathway being dimensioned so as to allow the block to burn by propagation of fire along the internal walls defining the pathway. The fire block will form an entire fire. A firelighter comprising a body of fire ignition material in the form of a webbed profile onto which a fuel to be ignited for combustion can be placed is also provided.
