Abstract: An article of manufacture for maximizing burn time of a jar candle. The lid features a dome with a top opening and a bottom opening. In its best mode of use, the lid is positioned on top of a burning jar candle, with the bottom opening resting on the rim of the jar candle. The lid captures heat at the surface of the burning wax, assisting in a full burn of the wax to the perimeter of the jar. A plurality of rim crescents encircles the bottom opening, to seal the lid's grip on the jar and to handle the lid when the dome is hot. The rim crescents have multiple ridges with sequentially smaller diameters, for fitting candle jars of varying sizes. Venting is provided by a cylindrical chimney extending downward from the top opening, as well as a plurality of holes in the dome.
