A wick is the part of a candle that enables the flame to exist. The NCA has several tips on how to burn them safely.
A wick delivers melted wax (the fuel) to the flame by capillary action. The rate of fuel delivery controls the size of the flame, how much heat is generated, the amount of melted wax that is created (more fuel), and the consumption rate of the candle. Wick type, size, location, and processing are critical for both candle safety and performance.
- A container candle’s wick should be properly secured to the bottom of the candle. During the burning of the candle, the wick should not move from the manufacturer’s original placement.
- A well-designed candle has a wick that keeps the candle’s heat and fuel delivery rate in balance. The wrong wick choice for any given candle can result in undesirable burn characteristics, such as large, sooty flames, or tunneling.
- Wicks are sensitive to changes in the candle-making process that can alter performance. Professionally engineered and processed wicks perform more consistently over the life of the candle.
