14 Claims

1. A candle comprising a meltable solid fuel element, a melting plate upon which the fuel element rests, and a wick holder comprising an upwardly extending wick carried by a wick holding means and heat conductive fins, wherein at least one of the heat conductive fins extends upwardly above the wick holding means and is positioned so as to collect heat from a flame upon the wick and to conduct such heat to the fuel element and to the melting plate, the wick holder engaging the meltable solid fuel element, and the heat conductive fins being insulated so as to prevent loss of the heat to the atmosphere, wherein at least one of the heat fins comprises an insulated portion interposed between a first uninsulated portion immediately proximate the flame and a second uninsulated portion of the wick holder in contact with the fuel element.
