Abstract
A candle construction incorporating a fuel core and a surrounding film having sufficient rigidity and/or stiffness along a vertical direction, to provide support for a fuel core which may be fabricated from a soft, cold-flowing or otherwise non-self-supporting material. The film is preferably fabricated from material(s) that are transparent or translucent, to permit visual inspection of the fuel core, and through the fuel core, if the fuel core is itself transparent or translucent. The film has a softening temperature range, the high end of which is greater than the high end of the melting temperature range of the fuel core material. When the fuel core material is molten and consumed through combustion, the film briefly remains in place to establish a vertical gap to contain the molten fuel material pool. The film may have one or more layers, with different materials and characteristics in the different layers.
