       11 . The fire log composition of  claim 1  comprising about 35% to about 65% by weight combustible material.  
   
   
       12 . The fire log composition of  claim 1  further comprising at least one compound selected from the group consisting of esters and olefins.  
   
   
       13 . The fire log composition of  claim 1  wherein the wax comprises polypropylene wax.  
   
   
       14 . The fire log composition of  claim 1  wherein the wax comprises alpha olefin wax and polyethylene wax.  
   
   
       15 . The fire log composition of  claim 1  wherein the combustible material comprises at least one material selected from the group consisting of sawdust, wood flour, vegetable fibers, vegetable flour, and/or mixtures thereof.  
   
   
       16 . The fire log composition of  claim 1  wherein the wax comprises at least one compound selected from the group consisting of polyethylene wax, polypropylene wax, vegetable oil esters, olefins, alpha olefins and/or mixtures thereof.  
   
   
       17 . The fire log composition of  claim 1  wherein the plant oil comprises modified tall oil pitch residue and the wax comprises polyethylene wax.  
   
   
       18 . The fire log composition of  claim 17  further comprising at least one other wax.  
   
   
       19 . A fire log composition comprising: 
 a combustible material;    a tall oil compound selected from the group consisting of modified tall oil, modified tall oil pitch, modified tall oil pitch residue, modified tall oil soap and/or mixtures thereof; and    a wax.    
   
   
       20 . The fire log composition of  claim 19  wherein the wax comprises polyethylene wax.  
   
   
       21 . The fire log composition of  claim 19  wherein the compound is modified tall oil pitch residue, said pitch residue having been saponified, neutralized, distilled, and acidulated.  
   
   
       22 . The fire log composition of  claim 19  wherein the log is comprised of about 50% by weight combustible material.  
   
   
       23 . The fire log composition of  claim 19  wherein the ratio of tall oil compound to wax is about 19:1.  
   
   
       24 . The fire log composition of  claim 19  wherein the ratio of tall oil compound to wax is about 4:1.  
   
   
       25 . The fire log composition of  claim 19  wherein the wax comprises alpha olefin wax and polyethylene wax.  
   
   
       26 . The fire log composition of  claim 25  wherein the ratio of tall oil compound to alpha olefin wax to polyethylene wax is about 80:10:10.
