Abstract:
A combination comprising:an apothecary jar candle including a vessel having a cylindrical body and an open circular mouth, a fuel source disposed within the body and burnt in the flame, and a wick extending from the fuel source, and is dimensioned such that the vessel body has a diameter approximately four inches across and a height between three inches and six inches tall, and the open mouth has a diameter approximately three inches across, and a venting plate for improving the stability and efficiency of the combustion flame of the candle, the venting plate including a flat circular body dimensioned to seat atop the mouth of the vessel, the body having a central exhaust vent through which combustion exhaust exits the vessel, and a plurality of peripheral inlet vents spaced around and radially from the exhaust vent through which ambient air is drawn into the vessel, the exhaust vent has a cross sectional area greater than 0.700 square inches and less than 0.900 square inches, the plurality of inlet vents have an aggregate cross sectional area greater than 0.600 square inches and less than 0.950 square inches, the exhaust vent and the intake vents are spaced apart from each other sufficiently to facilitate separated concentric laminar air flows of exhaust and ambient air within the candle vessel to ensure that sufficient ambient air is drawn to the base of the flame when the candle burns, the exhaust vent has a cross-sectional area and the inlet vents have a cross sectional areas, such that the ratio between the cross sectional area of the exhaust vent and the aggregate cross sectional area of the plurality of inlet vents is greater than 0.870 and less than 1.310.
