  From  Easton's  1897  Bible  Dictionary  [easton]: 
 
  Coal 
  It  is  by  no  means  certain  that  the  Hebrews  were  acquainted  with 
  mineral  coal,  although  it  is  found  in  Syria.  Their  common  fuel 
  was  dried  dung  of  animals  and  wood  charcoal.  Two  different  words 
  are  found  in  Hebrew  to  denote  coal,  both  occurring  in  Prov. 
  26:21,  "As  coal  [Heb.  peham;  i.e.,  "black  coal"]  is  to  burning 
  coal  [Heb.  gehalim]."  The  latter  of  these  words  is  used  in  Job 
  41:21;  Prov.  6:28;  Isa.  44:19.  The  words  "live  coal"  in  Isa.  6:6 
  are  more  correctly  "glowing  stone."  In  Lam.  4:8  the  expression 
  "blacker  than  a  coal"  is  literally  rendered  in  the  margin  of  the 
  Revised  Version  "darker  than  blackness."  "Coals  of  fire"  (2  Sam. 
  22:9,  13;  Ps  18:8,  12,  13,  etc.)  is  an  expression  used 
  metaphorically  for  lightnings  proceeding  from  God.  A  false 
  tongue  is  compared  to  "coals  of  juniper"  (Ps.  120:4;  James  3:6). 
  "Heaping  coals  of  fire  on  the  head"  symbolizes  overcoming  evil 
  with  good.  The  words  of  Paul  (Rom.  12:20)  are  equivalent  to 
  saying,  "By  charity  and  kindness  thou  shalt  soften  down  his 
  enmity  as  surely  as  heaping  coals  on  the  fire  fuses  the  metal  in 
  the  crucible."
