A candle is a lighting system that consists of a wick and wax. The wick, which is absorbent, pulls the liquid wax upwards by capillary action. The wax then vaporizes and reaches its ignition temperature, causing the candle to burn. While candles do not traditionally have needles, some candle-making kits include wicking needles, which are used to insert the wick into candle molds. In addition, some candles, such as coconut oil candles, may exhibit needle-like wax fibers on the inside after burning.

What You'll Learn
Candle wicking needles are used to make candles
Candle wicking needles are a crucial tool for candle-making. They are long, sturdy needles, often copper-coated, used to insert wicks into candles during the candle-making process. These needles are designed to be used with silicone moulds and tapers, and their length and sturdiness make them ideal for this purpose.
The eye of a candle wicking needle is typically narrow, allowing it to easily pass through different mould shapes and sizes. However, the eye can also be widened with a flathead screwdriver if needed. The needle's length, which is approximately 15 inches, enables it to reach deep into the candle moulds.
Candle wicking needles are sharp and require careful handling. They are not toys and should be kept out of the reach of children. When working with these needles, it is important to exercise caution to prevent injuries.
These needles are available in sets, often including multiple pieces, and can be purchased from various suppliers, including small businesses and large retailers like Amazon. They are commonly sold alongside other candle-making supplies, such as candle wicks and moulds.
In summary, candle wicking needles play a vital role in candle-making, specifically in inserting wicks into candle moulds. Their design, length, and sturdiness make them well-suited for this task, but caution must be exercised when handling them due to their sharpness.

Wicks absorb liquid wax and pull it upward
A candle's wick is a crucial component that enables the candle to burn. The wick must be made of a naturally absorbent material, such as cotton, or possess strong capillary action, as seen in glass fiber wicks used in oil lamps. This absorbency is essential because the wick needs to absorb the melted wax and draw it upwards through a process known as capillary action.
When a candle is lit, the heat from the flame melts the solid wax near the wick, turning it into a liquid. This liquid wax is then absorbed by the wick, which acts like a sponge, soaking up the molten wax. The wick draws the liquid wax upwards through tiny channels within its fibers, a phenomenon known as capillary action. This process is similar to how a paper towel absorbs and draws up water through capillary action.
The absorbed wax then vaporizes and burns, producing light and heat. The vaporizing wax also cools the exposed wick, preventing it from burning away too quickly. This cooling effect is similar to the camping trick of boiling water in a paper cup, where the water inside keeps the cup from burning. In the case of the candle, the liquid wax cools the wick, allowing it to slowly burn while sustaining the flame.
The type of wax used in candles, such as paraffin wax, a byproduct of petroleum, also plays a role in the burning process. Paraffin wax has a high ignition temperature, so it needs to be heated to a high temperature for combustion to occur. The wick helps to achieve this by drawing the wax upwards and exposing it to the flame's heat, allowing the wax to vaporize and reach its ignition temperature.
Additionally, the size of the wick is important to ensure complete combustion. If the flame is too "rich," meaning there is an excess of wax vapor, some of the unburned soot may escape into the room. However, with the correct wick size, most of the soot particles are consumed in the flame, resulting in the production of light, heat, water, and carbon dioxide.

Wicks need to be absorbent or have capillary action
Wicks are an essential component of candles, facilitating the capillary action necessary for the candle to burn. A wick's key characteristic is its absorbency, enabling it to draw and transport fuel to the flame. This absorbency is a result of the wick's porous nature, which allows it to act like a sponge, soaking up the melted wax.
The process of capillary action involves the flow of liquid within a narrow space without the aid of external forces like gravity. This phenomenon is observed when a porous medium comes into contact with a liquid, causing it to absorb the liquid. Over time, the rate of absorption decreases. Capillary action is influenced by factors such as temperature, humidity, and permeability.
In the context of candle wicks, capillary action enables the upward flow of liquid fuel, such as melted wax, through the wick. This flow occurs due to intermolecular forces between the liquid fuel and the solid surfaces of the wick. The small pores in the wick act as capillaries, drawing the liquid upwards through a combination of surface tension and adhesive forces.
To enhance the capillary action in candle wicks, specific tools like wicking needles are used during the candle-making process. These needles, often copper-coated, aid in the placement and positioning of the wick within the mould. They ensure that the wick is properly centred and secured, allowing for optimal capillary action when the candle is lit.
The choice of wick material also plays a crucial role in capillary action. Synthetic fibres like nylon or polyester are commonly used due to their durability and effectiveness in capillary action. However, natural fibres such as cotton have also been utilised in candle wicking for centuries.

Wicking needles are sharp and dangerous
Wicking needles are sharp tools used in candle-making. They are long, thin, and sturdy, and often coated in copper. They are used to insert wicks into candles during the production process. Wicking needles are sharp and pose a danger, particularly to children, due to their narrow and pointed shape. They can easily pierce the skin and cause injury.
Wicking needles are designed to fit through candle molds of various shapes and sizes. They are inserted into the mold to place the wick, ensuring it is centred and secure. The eye of the needle, through which the wick is threaded, can be very narrow, allowing it to pass through small openings in the mold. However, this sharp and narrow eye also contributes to the hazardous nature of these needles.
The sharpness of wicking needles is important for their functionality, as they need to penetrate the wax and create a path for the wick. They are also useful for creating holes in the wax and adjusting the position of the wick if needed. The pointed tip of the needle allows for precise and controlled penetration of the wax, ensuring an even and stable wick placement.
While wicking needles are essential for candle-making, they require careful handling and storage. It is crucial to keep them out of the reach of children and to handle them with caution to prevent accidental injury. Proper safety measures, such as storing them in a safe place and handling them with care, can help minimise the risk of harm.
In addition to their functionality in candle-making, wicking needles can also be used for other crafts. For example, they can be utilised for punch needling, a craft that involves creating designs or images by repeatedly pushing a needle in and out of a fabric. Wicking needles can be useful for this purpose due to their length and sharpness, allowing them to penetrate various materials effectively.
