What You'll Learn
The centre of a candle wick is called the 'core'
The centre of a candle wick is called the core. It is made of materials such as zinc, cotton, or paper. The wick is a crucial component of a candle, as it is responsible for drawing fuel (molten wax) up from the candle body, allowing it to burn.
Wicks are often infused with chemicals to modify their burning characteristics. For example, additives are used to prevent the wick from glowing after the flame is extinguished. Other additives, such as fragrance oils, dyes, or crayons, are used to enhance the candle's scent, colour, or appearance. However, these additives can sometimes lead to wick clogging if they are not properly formulated for use in candles.
To avoid wick clogging, it is important to use only colourants and additives specifically designed for candle-making. Additionally, proper wick sizing is essential to prevent issues such as hang-up and tunnelling, where the wax does not melt evenly, resulting in an uneven burn and wax left along the edges of the container.
The size of the wick affects the burn rate and flame size of the candle. A wick that is too large can produce an excessively high flame, while a wick that is too small may not provide sufficient fuel for the candle to burn properly, leading to tunnelling. Therefore, choosing the appropriate wick size is crucial for optimal candle performance.
In summary, the core, or centre of the candle wick, plays a vital role in the candle's burning process. Proper wick selection, preparation, and maintenance are essential to ensure a clean, efficient, and aesthetically pleasing candle-burning experience.

'Wick up' and 'wick down' refer to wick sizing
The core of a candle is the centre of its wick. When it comes to candle-making, the terms "wick up" and "wick down" refer to the sizing of a candle's wick.
"Wicking up" means increasing the diameter of the wick, whereas "wicking down" means choosing a wick that is smaller in size. If a candle is under-wicked, it will not burn to the edge of the container but will instead burn down the middle, or "tunnel". Conversely, a candle with a wick that is too large will produce a tall, continually flickering flame, deep carbon build-up, and excess carbon that causes "mushrooming" at the end of the wick.
The size of a candle's wick is important as it affects the rate of fuel consumption and the burning temperature. Wicks are often infused with chemicals to modify their burning characteristics. For example, ammonium nitrate and ammonium sulfate are used to prevent the wick from glowing after the flame is extinguished.
To choose the proper wick size, one must consider the type of wax, additives, and fragrances used in the candle. For instance, "Single Pour" paraffin waxes and vegetable-based (soy) waxes generally require a larger wick, whereas "Single Pour" paraffin waxes generally require a smaller wick. Additionally, larger diameters require larger wicks, and if fragrances are added, a larger wick size may be necessary.

'Wick pin' is a metal component to centre wicks in pillar candles
The core of a candle is the centre of the wick. In candle-making, the core may refer to the interior of the candle or the inner material of the wick, which can include zinc, cotton or paper.
A wick pin is a metal component used to centre wicks in pillar candles. It is part of a pillar mould that creates a hollow cavity for the wick. Once the wax has been poured into the mould and set, the candle is removed, and a wick can be inserted into the hole created by the wick pin.
Wick pins are not the only tools used to centre a wick. A stabilising bar is a reusable metal tool that centres a wick and holds it in place when a candle is poured. A wick tab, meanwhile, is a flat metal disc with a small hole in the centre for a wick, which holds the wick at the bottom of a candle.
Wicks are often infused with chemicals to modify their burning characteristics. For example, it is usually desirable that the wick does not glow after the flame is extinguished. Typical agents used to achieve this include ammonium nitrate and ammonium sulfate.

'Wick tab' is a metal piece to hold the wick in place
The core of a candle refers to the centre of a candle wick. In candle-making, a wick tab is used to hold the wick in place. This is a flat, round metal disc with a small hole in the centre for the wick to pass through. The wick tab is placed at the bottom of the candle, securing the wick in place. It is sometimes referred to as a wick clip or wick sustainer.
Wick tabs are an essential part of the candle-making process. They ensure the wick stays in place as the wax is poured into the mould. The tab is placed at the bottom of the mould, with the wick passing through the hole, and the wax is then poured on top. Once the wax has set, the wick tab holds the wick securely in place, ensuring the wick doesn't move or shift during use.
The use of a wick tab also aids in the attachment of the wick to the candle container. This is particularly important for container candles, which are candles made inside a vessel such as a glass, metal, or ceramic jar. The wick tab provides stability and ensures the wick remains centred in the container.
Wick tabs are typically made of metal and are reusable. They are an important tool for candle makers, ensuring the wick remains in place during the pouring and setting process, and providing stability and security during the burning of the candle.
In summary, a wick tab is a metal piece that plays a crucial role in holding the wick in place, both during the candle-making process and when the candle is being used. It is a flat, round disc with a hollow centre, allowing the wick to pass through and be securely attached to the bottom of the candle.

'Wick sustainer' is a flat metal disc with a hole for the wick
The core of a candle refers to the centre of its wick. In candle-making, a wick sustainer is used to hold the wick in place at the bottom of the candle. It is a flat metal disc with a small hole in the centre for the wick to pass through. The disc is affixed to the bottom of the candle container with a double-sided sticky pad. This type of wick sustainer is usually round and has a short, hollow "neck" that holds the wick securely in place.
Wick sustainers are also known as wick tabs or wick clips. They are often made of metal and are used to centre the wick and hold it in place when the candle is poured. They are completely reusable.
Wick pins are another type of metal component used to centre wicks in pillar candles. They are part of a pillar mould that creates a hollow cavity where the wick will go. The wax is poured into the mould and, once hardened, the wax is removed and a wick is inserted into the hole created by the wick pin.
Candles with wicks that are too small for their containers may experience tunnelling, where the wick burns straight down the centre of the candle without creating a full melt pool.
