The wick is an important, yet often overlooked, component of a candle. It is responsible for delivering fuel (wax) to the flame and influences how the candle burns. Wicks are typically made from braided cotton, but can also be made from other materials such as wood, hemp, paper, linen, and even silk. The type of wick used depends on the candle's size, shape, colour, and fragrance. Choosing the right wick size is crucial to ensure the candle burns properly and cleanly. Some wicks are also treated with chemicals to reduce smoke and soot, and to make them self-trimming.

Wicks are typically made from braided cotton
Wicks are an essential component of candles, responsible for delivering fuel (wax) to the flame. The type of wick used depends on the candle's size, shape, colour, and fragrance. While there are hundreds of wick varieties, those made from braided cotton are the most prevalent.
Braided cotton wicks are constructed by interlacing cotton strands to form a sturdy wick that holds the candle's flame. Cotton is a preferred material due to its ability to absorb wax effectively. The braiding technique also encourages a slow and consistent burn, making it a popular choice for high-quality candles.
Cotton wicks are widely used in scented candles due to their natural fibres, which enhance the diffusion of fragrance. They are also known for their durability, capable of burning for extended periods without extinguishing. Additionally, cotton wicks are environmentally friendly and aesthetically pleasing, making them a popular option for candle manufacturers.
The preparation of cotton wicks involves coating them in wax to ensure a longer-lasting candle. The wicks are then hung to dry, with the excess wax dripping off. This process is crucial for the functionality and performance of the wick.
While cotton wicks are predominantly braided, they can also be flat-braided or coreless with a paper filament woven into the braid. Flat-braided wicks are designed to curl back into the flame, making them self-consuming and self-trimming. Coreless wicks, on the other hand, are designed to bend at the tip, forcing the wick into the hottest part of the flame for optimal burning.

Wooden wicks are popular for their visual and auditory appeal
Candle wicks are typically made from braided cotton, but they can also be made from other materials such as hemp, paper, linen, silk, and wood. The type of wick used depends on the candle's size, shape, colour, and fragrance materials. The choice of wick is critical to ensuring the candle burns cleanly and properly.
Wooden wicks have gained popularity in recent years for their visual and auditory appeal. They are available in various styles, including single-ply, multi-layered, curved, and decorative shapes. Wooden wicks create a unique visual aesthetic with their simple, rustic, and modern design. They are typically thin, flat strips of wood emerging from the top of the candle, adding a novel touch to the overall appearance.
One of the most distinctive features of wooden wicks is the soft crackling sound they produce when burned, reminiscent of a fireplace. This crackling effect adds an auditory dimension to the candle experience, creating a cosy and relaxing atmosphere. The sound is a result of the capillary action, where the wick draws liquefied wax upwards towards the flame, similar to traditional cotton wicks.
While wooden wicks may have fewer style variations than cotton wicks, they offer a unique visual and auditory experience that has captured the interest of candle enthusiasts. Their ability to stand upright in the container during wax pouring and hardening also makes them easier to work with. Wooden wicks are a relatively recent addition to the candle-making world, and their distinct characteristics have contributed to their growing popularity.
It is important to note that wooden wicks require more maintenance than cotton wicks. Unlike many self-trimming cotton wicks, wooden wicks need to be trimmed before each burn to ensure optimal performance and prevent debris from falling into the melted wax.

The correct wick is critical for a candle to burn properly
Wicks are typically made from braided cotton, but can also be made from hemp, linen, paper, and wood. Historically, wicks have even been made from asbestos. The type of wick used depends on the candle's wax type, fragrance load, dye type, and container diameter. For example, flat wicks, made from three bundles of fibre, are very consistent in their burning and curl in the flame for a self-trimming effect. On the other hand, twisted wicks burn much faster because their loose construction allows more fuel to reach the flame.
Stiffeners are used to direct the wick to remain upright so that fuel can reach the flame. While stiffeners were once made from lead, they have been banned in the US due to concerns about lead poisoning. Fine wire, such as copper, paper, and synthetic fibres are now used as core stiffeners.
Wooden wicks have become popular in recent years for the visual aesthetic and soft crackling sound they create. They are available as single-ply, multi-layered, curved, and decorative shapes, made from 100% wood, semi-wood, fibrous material, or cotton and wood combinations.

Wicks can be made from other materials such as hemp, paper, linen, silk, and historically, asbestos
Candle wicks are typically made from braided cotton, which draws the liquefied wax up into the flame. However, wicks can also be made from other materials such as hemp, paper, linen, silk, and historically, asbestos.
Hemp wicks are not commonly used today, but they can be a natural and sustainable alternative to cotton wicks. They are known for their durability and ability to burn slowly and consistently. Hemp wicks are also said to produce less smoke and soot, making them a cleaner option for candle-making.
Paper wicks are another alternative to cotton wicks and are known for their controlled curling, which results in minimal mushrooming, soot, and smoke. Paper wicks are often used in eco-friendly candles as they are primed with vegetable wax rather than paraffin wax. However, paper-cored wicks may produce more "afterglow" and smoke than other types of wicks.
Linen wicks share similar characteristics with cotton wicks in terms of their ecological and sustainable nature. However, linen wicks are more aesthetically pleasing and resistant to deformation, even under significant thermal shock. Linen wicks are often used in scented candles as they can withstand high temperatures without compromising their structure.
Silk wicks are also a natural option for candle-making, known for their resistance and durability. However, silk wicks are rare and expensive due to the nature of their production, which relies on silkworms. Synthetic silk is available as a more affordable alternative, but it is not as environmentally friendly as its natural counterpart.
Historically, asbestos was used as a wicking material for candles. However, due to health and safety concerns, this practice has been discontinued, and other materials such as wood, cotton, and paper have become more common.

Stiffeners are used to direct the wick and can be made from wire, paper or synthetic fibres
Candle wicks are typically made of braided cotton, which holds the flame and draws the liquefied wax up into it through capillary action. The size of the wick is important as it determines how much fuel reaches the flame. If too much fuel reaches the flame, it will flare and soot; too little, and the flame will sputter out.
Stiffeners are used to direct the wick and ensure it remains upright so that fuel can reach the flame. They can be made from wire, paper, or synthetic fibres. Historically, stiffeners were made from lead, but these have been banned in the US due to concerns about lead poisoning.
The use of wire as a stiffener can make the wick more rigid, allowing it to stand further out of the liquid wax. It also conducts heat downward, melting the wax more readily. This is particularly useful for candles made of harder wax.
Paper has also been used as a stiffening agent for wicks. The Chinese, for example, used rice paper to create wicks, along with wax made from insects and seeds.
Synthetic fibres are another modern alternative to wire and paper stiffeners. These artificial wicks are considered more economical than natural fibre wicks.

Frequently asked questions
Candle wicks are most commonly made from braided cotton. However, they can also be made from other materials such as hemp, linen, wood, paper, silk, and historically, even asbestos.
There are hundreds of different styles and sizes of wicks. Some common types include flat wicks, booster wicks, spiral or tube wicks, crackle wicks, and whisper wicks.
Candle wicks act as a fuel pump, drawing the liquefied wax up into the flame through capillary action. The wick's diameter, stiffness, fire resistance, and tethering influence how the candle burns.
To make a candle wick at home, you will need string and wax. Cut the string to the desired length depending on the type of candle you are making. Tie weights or screws to the ends of the string to help it dry straighter. Melt the wax and soak the strings in the liquid wax for at least one minute. Hang the wax-coated strings on a drying rack to cool and harden.
