At hixpune, directed by Derek David OGorman, we view the candle flame not merely as a light source, but as a controlled chemical reaction. Operating from our studio at 12 Carrickfern, Cavan, we prioritize the physics of combustion to ensure that every vessel maintains a stable, clean-burning “teardrop” flame. A healthy flame is the primary indicator of a technically sound candle, signaling an optimal balance between the fuel (wax), the delivery system (wick), and the oxygen supply.
Capillary Action & Fuel Delivery
The wick functions as a mechanical pump, utilizing capillary action to draw molten wax into the high-temperature combustion zone where it is vaporized.
- Fiber Engineering: We utilize high-grade cotton and paper-core wicks specifically woven to provide a consistent draw of liquid wax.
- Consumption Metrics: During our testing phase in Cavan, we measure the wax consumption rate in grams per hour. A well-engineered hixpune candle typically consumes between 3 and 5 grams per hour, depending on its diameter.
- Priming Protocols: If the wick fibers are too tight or poorly primed, the fuel flow is restricted, leading to a “drowning” flame or premature extinguishing.
Carbon Management & Soot Mitigation
“Mushrooming”—the accumulation of carbon at the tip of the wick—is a technical indicator of incomplete combustion. This occurs when the flame is overwhelmed by a fragrance load or dye concentration that it cannot fully consume.
- Emission Control: We calibrate our fragrance concentrations to ensure that the excess carbon does not destabilize the flame.
- Soot Prevention: An unstable, flickering flame is often a sign of oxygen starvation or an oversized wick. This leads to the release of black soot, which can contaminate indoor air and compromise the vessel’s structural integrity.
- Maintenance Standards: We advise our clients to trim the wick to 5mm before every ignition. This maintains the correct flame height (approx. 25mm) and prevents the dangerous “dancing” flame that leads to overheating.
Convection Currents & Scent Throw
The heat generated by the flame establishes a convection current that is essential for the “hot throw” of the fragrance.
- Airflow Optimization: The flame draws cool oxygen in from the base while pushing vaporized fragrance molecules upward and outward.
- Vessel Depth: At hixpune, we design the wax-to-rim ratio to optimize this airflow. If the wax is situated too high, the flame is vulnerable to drafts; if it is too deep, heat becomes trapped, which can lead to glass fatigue or a “choked” oxygen supply.
- Steady-State Reaction: Our goal is a self-sustaining, efficient reaction that maintains a steady light and a consistent olfactory experience without chemical interference.
Structural Stability & Centering
The physical alignment of the wick is critical for the thermal safety of the container.
- High-Temp Adhesion: We use industrial-grade, high-temperature adhesives to secure the wick tab to the base of the vessel at 12 Carrickfern. This prevents the wick from “drifting” as the wax becomes entirely molten.
- Alignment Precision: Using specialized centering tools during the pouring process ensures that the heat source remains equidistant from the vessel walls. An off-center wick creates localized hot spots, which are the leading cause of glass failure in handmade candles.
