Coal is judged according to the feet of the owner, but the flame can be taken anywhere. Five things were said about the charcoal: one can commit the sin of embezzlement with charcoal from consecrated material, but regarding its flame - one can neither benefit nor commit the sin of embezzlement with it. Coal from idolatry is forbidden, but its flame is permitted. If one brings coal into public domain he is guilty, but if he brings the flame there he is free. If a man is forbidden by a vow to take benefit from another, his coal is forbidden to him, but he is permitted with his flame. One say a benediction over the flame, but one does not say a benediction over the coal.
