A candle assembly includes a support base, a melting plate having a capillary pedestal, a wick holder that fits onto the capillary pedestal, and a fuel element that fits over the wick holder. The wick holder includes a sleeve having first and second open ends. A wick fits into the sleeve and extends between the open ends. The sleeve has a constricted portion, which is disposed between the open ends and has a cross-sectional area less than any other cross-sectional area between the open ends. The constricted portion reduces an effective capillary fluid flow capacity of the wick between the open ends, which may thereby regulate how quickly fuel is consumed when the candle assembly is burning. 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.

We claim: 1. A candle assembly, comprising: a capillary pedestal disposed on a melting plate; and a wick holder having a base that cooperatively engages the capillary pedestal and forms a capillary space therebetween; wherein the capillary space defines a capillary well having a volume sufficient to contain an amount of meltable fuel to feed a flame on a wick carried by the wick holder, wherein a proportion of the volume to the thermal mass of the candle assembly is more than or equal to about 1 cubic millimeter per calorie per degree Celsius of the candle assembly, wherein a proportion of the volume to the thermal mass of the candle assembly is less than or equal to about 10 cubic millimeter per calorie per degree Celsius of the candle assembly, and wherein the thermal mass of the candle assembly is between about 135 calories per degree Celsius and about 10 calories per degree Celsius. 2. The candle assembly of claim 1, wherein the capillary well is configured to supply the wick with fuel for a period of time required to melt an amount of a solid meltable fuel adjacent to the wick holder sufficient to provide a substantially continuous flow of melted fuel into the capillary space. 3. The candle assembly of claim 2, wherein the capillary well is configured to allow heat from the flame to melt the meltable fuel contained in the capillary well sufficiently rapidly to replace fuel carried in the wick that is burned by the flame. 4. The candle assembly of claim 1, wherein the volume is proportional to a thermal mass of the candle assembly. 5. The candle assembly of claim 4, wherein the thermal mass of the candle assembly is between about 75 calories per degree Celsius and about 40 calories per degree Celsius. 6. The candle assembly of claim 4, wherein the thermal mass of the candle assembly is between about 61 calories per degree Celsius and about 50 calories per degree Celsius. 7. The candle assembly of claim 6, wherein the candle assembly includes a fuel element having a thermal mass between about 10.5 calories per degree Celsius and 0 calories per degree Celsius. 8. The candle assembly of claim 1, wherein the volume is more than about 100 cubic millimeters. 9. The candle assembly of claim 1, wherein the volume is less than or equal to about 500 cubic millimeters. 10. The candle assembly of claim 1, wherein the volume is about 200 cubic millimeters. 11. A wick holder for a candle assembly including a capillary pedestal, the wick holder comprising: a base portion that fits aronud the capillary pedestal to define a capillary well between the base portion and the capillary pedestal; wherein the capillary well is able to contain an amount of fuel sufficient to feed a flame on a wick carried by the wick holder for a period of time, and wherein the capillary well defines a volume between about 100 cubic millimeters and about 500 cubic millimeters. 12. The wick holder of claim 11, wherein the capillary well defines a volume of about 200 cubic millimeters. 13. The wick holder of claim 11, wherein the base portion includes a skirt extending from an outer periphery of an end wall. 14. The wick holder of claim 13, wherein the end wall has a diameter between about 11 mm and 14 mm, and the skirt has an outer diameter between about 20 mm and 23 mm and a height between about 7 mm and 4 mm. 15. The wick holder of claim 11, wherein the base portion includes a skin extending from an outer periphery of an end wall, and wherein the spacer extends from the end wall. 16. The wick holder of claim 15, wherein spacer extends between about 0.1 mm and 1 mm. 17. A candle assembly comprising: a capillary pedestal disposed on a melting plate; and a wick holder having a base that conforms to the capillary pedestal to form a capillary space therebetween that defines a capillary well having a volume; wherein a proportion of the volume to the thermal mass of the candle assembly ranges from about 0.00006 in3/cal/�� C. (1mm3/ cal�� C.) to about 0.0006 in3/cal�� C. (10mm3/cal/�� C.). 18. A wick holder for a candle assembly including a capillary pedestal, the wick holder comprising; a base portion that fits around the capillary pedestal to define a capillary well between the base portion and the capillary pedestal, wherein the base portion includes a skirt extending from an outer periphery of an end wall; and a spacer that extends from the end wall; wherein the spacer maintains a predefined space between the base portion and the capillary pedestal, whereby the capillary well is able to contain an amount of fuel sufficient to feed a flame on a wick carried by the wick holder for a period of time. 19. The wick holder of claim 18, wherein the spacer comprises a rivet.
