Abstract
A candle assembly includes a melting plate having a capillary pedestal, a wick holder that fits over the capillary pedestal, a wick that is carried by the wick holder, and a fuel element that fits over the wick and wick holder and rests on the melting plate. The fuel element includes a duct therethrough for receiving the wick holder. The fuel element is adapted to prevent improper insertion of the wick holder into the duct. The duct is adapted to facilitate successful initial ignition and sustained burn of the wick by having a width that is selected to ensure that melted fuel material engages the wick when dripping down the duct. A capillary well disposed between the wick holder and the capillary pedestal may be adapted to promote a successful relight after an initial burn of the candle assembly. A candle holder, such as including the melting plate supported by a base, may be adapted to promote laminar air flow thereacross during a burn in a substantially calm atmospheric environment.
