If you want a crackle wick candle, then your candle must have a wooden wick! When any wood is heated, its molecules start to break down and release water vapour. This water vapour can become trapped in the pores of the wood, creating small pockets of air. As a wooden wick candle burns, the heat from the flame causes these pockets of air to expand. Eventually, the pressure inside the pockets becomes too great and they 'explode', releasing a burst of steam - this creates the desirable candle crackling sounds.

The Science Behind the Candle Wick Crackling
Wooden wicks crackle because of three main reasons.
The Structure of the Wick
Wood is composed of thousands of tiny cells that contain air and moisture. When the wood is heated by the flame, the air and moisture expand and escape through the cracks in the wood, creating a popping sound. This is similar to what happens when you burn wood logs in a fireplace.
The Shape of the Wick
Wood wicks are usually flat and wide, which creates a larger and more horizontal flame as compared to cotton wicks. This flame draws more air from the sides of the wick, creating turbulence and noise. This is different from cotton wicks, which are usually round and thin, and create a smaller and vertical flame.
The Candle Wax
Candle wick crackling is caused when wooden wicks are used together with natural, eco-friendly plant-based candle waxes, such as soy, coconut or rapeseed waxes. The wooden wicks, usually made of a softwood such as cedar, release tiny pockets of trapped air as they burn. These pockets of air expand rapidly as they heat up and then escape, creating a crackling sound reminiscent of the sounds of a crackling log fire.
The crackling sounds produced by wood wicks depends on the wood used in the wick, the size of the wick, and the candle wax used. In general, softwoods like pine, cedar and fir produce more crackling than hardwoods like oak and maple. Larger wicks will produce more crackling sounds than smaller wicks and plant-based waxes such as soy wax, will produce more crackling sounds than waxes such as paraffin wax.
The Benefits of Wood Wicks
Wood wicks are not only appealing for their crackling sound, but also for their other benefits.
Creating a Relaxing Ambience
The crackling sound can help you unwind and relax. The combination of light and sound from wooden wicks creates a great ambience.
Longer and Cleaner Burn
Wooden wicks are more efficient than cotton wicks, as they consume less wax and produce less soot. They also create a wider melt pool, which releases more fragrance into the air.
Wooden wicks are usually made from natural and renewable sources, such as trees or plants. They do not contain any chemicals or additives that can harm the environment or your health.
