All You Need To Know About Crackle Wick Candles

With the popularity of aroma therapy and candles becoming a huge part of home décor, the candle-making industry has really elevated. They have introduced new and better versions of candles and waxes, such as crackle wick candles and popping candles

In this article, we will discuss everything you would love to know about crackle wick candles

So, let’s get a wing to it without any further ado. 

What are wicks made of? 

A crackling wick is made from multiple materials such as yarns or strings. Plus another essential material is wood. 

As you must know, the crackling wood wick is one of the most commonly found types. Below is a quick list of all types of wicks: 

  1. Cotton wicks
  2. Zinc core wicks
  3. Paper core wicks
  4. Wood wicks

Crackling wood wick: 

These wicks are usually made from balsa wood- a light, strong, and fast-growing wood. Their format can be flattened, crossed, or in a tube; hence, the thickness is always thin. 

Moreover, it produces an ample and high flame which facilitates the formation of the wax pool (therefore, they can promote the risk of being submerged if the wax melts too quickly) 

Interestingly, their most cherished quality is that they crackle, giving the sensation of a fireplace. Also, they work best for popping candles that contain paraffin, soy, or palm. 

A quick tip: Some wooden wicks need to be soaked in oil before they can be used in candles. The downside is that this wet wood goes rancid very quickly, which can spoil the candle wax and produce a smelly flame.

Do all wood wicks crackle? 

Wood wicks are made of softwood. To make the wood ready for crackling wick candles, the wood is dried out, which creates gaps in the wood, leaving behind small pockets of water. 

When the wood wick is burned, the water pockets release steam which causes the candle crackling sound.

So this answers your question, “do all wood wicks crackle?” Yes, they do! 

Many people find this candle crackling sound very fascinating, which is why crackle wick candles are getting famous every day.

How to take care of crackle wick candles?

Vegetable candles, although they may seem safe, need to be treated with the same care as you would any other flammable product with the risk of catching fire, 

Important:  Vegetable candles are dangerous if not watched and attended to.

Candle wax risks catching fire if overheated; for this reason, it is imperative to follow the instructions for safe use and conservation, remembering that this applies to any candle! 

Here’s what you can do:

  • Minimize risks
  • increase the burning time
  • lighting correctly
  • protect yourself and your candle

How to light crackling wood wick candles? 

The crackling of the flame of the candles with wooden wick creates a sophisticated and cozy atmosphere, but they have special care in burning.

Tip: You should light your candle by tilting it slightly to let the flame draw along the length of the wick. 

The first burn is the most important!!! 

  • Give your candle enough time to melt by letting the wax reach the edges of the glass on the first burn, forming a complete melting pool.
  • This can take approximately 15 min. 
  • Crackling wick candles have burn memory. Once a burn pattern has been established, it can be more work to change. 
  • So enjoy your crackle wick candles; leave them lit until the wax melts to the edge of the glass. 
  • Incorrect burning

The wax pool has not yet reached its time; wait until it reaches the edges of the cup, preventing tunneling from occurring and having problems staying lit

  • Correct burn 

An even pool full of melted wax is a healthy candle and can be extinguished with safety for the following fires

Do not leave the candles that crackle on for more than 2 hours (170gr)!

We suggest you not leave it on for more than 2 uninterrupted hours and do not light it when 1 cm is missing from the end of the candle as the oil can overheat, and it is not safe to handle the container or the massage oil.

So, just erase with the lid, and let it cool to reuse your pot creatively.

Extinguish the candle with the lid only and never blow or use water! 

Never try to extinguish any candle using water (it should not be where you can find drops of water, such as in the shower or the kitchen near the faucet). Instead, always use the cap with it or a damper to erase.

Trimming the wick with each burn

The crackling wick needs to be trimmed to clean the charred material. Did you know that it is not the wood that fuels the candle flame but the wax and oils? The wick is a conductor, so it must remain clean and trimmed.

Trimming is very simple; it works great with your fingers and a napkin or using a nail clipper!

Just let your candle cool before trimming it, as it’s much easier to clean the wick when the wax is hard and cold!

How to fix crackle wick candles that are tunneling? 

If your sail has formed a tunnel, you can fix it; here’s how:

  1. The first and best option to stop tunneling in candles that crackle is to light it and leave it on for quite a while until the wax melts, reaching the rim of the cup, be patient for it to create a pool of fusion.
  1. Another way is to dispense with the oil that has already been burned; if it is hard, scrape the already burned wax, trying to level the mass, clean the edges of the glass nicely and relight your candle, letting it burn again until the oil reaches the edges to level and create a new vegetable wax memory
  1. The third way to level the mass is to use a hair dryer to heat and melt the wax of your crackle candle; use the dryer in a circular fashion over the top of the candle.

Differences between wood wick crackle candle and cotton wick candles:

Below is a quick table to equip you with some fun differences between the wood wick and cotton wick 

Wood wickCotton wick
Produces candle crackling soundNo sound is produced
More coverage is achieved Gives less coverage 
Burns more efficiently Burns less efficiently 
They are rigid Cotton wicks are not rigid
It provides an even burn Burns unevenly, causing tunneling 

FUN FACT: Crackle wick candles are preferred over conventional candles as they enhance all of our senses and are especially helpful in therapy. 

What is the ideal wick for candles? 

Answering this is very complex and variable. Each wick will behave differently depending on wax combinations and types, container sizes, and fragrance types. 

Also, note that the different sizes of wicks cause different amounts of wax (fuel) to be pulled into the flame. 

For example, soy wax needs a thicker wick than paraffin to create the wax pool in the same amount of time. 

Therefore, the ideal is to do several tests with different wicks, different cures, different containers, and different burning times. Thus, you can determine the best material for your type of wax, candle duration, cups, and combinations with additives. 

For crackle wick candles in containers, the ideal result is one where the mixture of waxes, additives, and the wick, manage to create a uniform flame that, in the burning of 2-3 hours, creates a pool of wax throughout the diameter of crackle candle glass. 

How to check if the wick size is incorrect? 

Here is a list of things you will notice if you are using the wrong wick for your candle:

  1. The candle burns too low
  2. Keeps going out
  3. An uneven wax pool is forming 
  4. Tunneling 

You can fix these problems by either changing the size of your wick or the size of your container. If your container is wide, you can also increase the number of wicks. 

ATTENTION: It is mandatory to use eyelets at the bottom of the containers while using any wicks, especially in glass cups and jars. The eyelet ensures that when the candle reaches the end of its burn, the heat of the wick is not responsible for bursting the glass! 

What crackling wick thicknesses can we find? 

Wooden wicks are commonly available in a variety of thicknesses. They mainly vary between 2mm to 19mm. You can get yours based on your needs. 

The two essential things you need to know are: 

  1. The thickness or width of the wick determines the diameter of the burn. A few centimeters of a pool of wax are produced around the flame every 1 hour of burning. 
  1. The height of the wick determines the height of the flame. The higher the flame, the more the fire will fluctuate, and the burn tends to be incomplete combustion. Therefore, do not make your wick longer than 0.5 centimeters. 


Crackle wick candles are a great option for home décor as well as aroma therapy. They create a very comfortable and romantic environment. We hope you found answers to all your queries in this blog. 

Happy candling!
