    Abstract: An improved synthetic fire log is disclosed which contains wood fibers or sawdust, coal liquid, molasses and paraffin wax in appropriate quantities. Green sawdust is first heated to a temperature of from 250 to 300 degrees F. to reduce the moisture content thereof and provide relatively dry sawdust. To the dry sawdust is added a quantity of coal liquid while the sawdust is at an elevated temperature of at least 200 degrees F. Next, molasses is added to the sawdust, coal liquid combination while the combination is in a temperature range of from 115-150 degrees F. Thereafter, paraffin wax in block form is added while the foregoing mixture is at an elevated temperature at least sufficient to melt the paraffin. Upon thorough incorporation of the materials, the resulting mixture is poured into a mold and compressed to form a stable, solid, compacted mass after which the mass is removed from the mold thus forming an improved synthetic fire log.
