ABSTRACT:
An artificial firelog is formed of an elongated flammable body of compressed sawdust and a wax binder which is sealed within a flammable outer protective wrapper. A groove, generally dovetailed-shaped in transverse cross section, extends throughout the longitudinal length of the body in a vertical lower portion of a front surface of the body. The upper portion of the front surface is inclined rearwardly and terminates in a horizontal top surface. The groove forms a venturi air passage within the wrapper interior which creates a draft to accelerate burning of the wrapper and the flammable body along the top of the groove when the wrapper is ignited adjacent one end of the groove. A second groove is formed in the top surface of the body to control the weight of the body during the extrusion forming thereof.
