Candle Making Vocabulary in English

A wick is the braided cord running through a candle that draws up melted wax and burns to create the flame. Choosing the right wick size is essential: too small and the candle will tunnel, too large and it will smoke or burn too fast. Wick choice depends on the wax type, the container's width, and the fragrance load.

Soy wax is a plant-based wax that generally burns cleaner and more slowly, and many customers prefer it as a natural option. Paraffin is a petroleum-based wax that is affordable, holds fragrance strongly, and is common in pillar candles because it can hold detailed shapes well. Both are widely used, and the choice often depends on burn style and personal preference.

Tunnelling happens when a candle burns straight down the centre, leaving a ring of solid wax untouched at the edges. It is usually caused by an undersized wick or by extinguishing the candle before the melted wax pool reaches the container's edge on its first burn. Using the correct wick size and allowing a full first burn helps prevent it.

Cold throw is how strongly a candle's scent can be detected when it is unlit, which helps buyers judge fragrance while shopping. Hot throw is how strongly the scent fills a room while the candle is actually burning, which matters most for the finished experience. A candle can have a strong cold throw but a weaker hot throw, or the reverse.

To cure a candle means to let it rest, often for about two weeks, after it has been poured. During this time the wax fully hardens and the fragrance oil binds more evenly throughout it, which usually improves the hot throw. Burning a candle too soon after pouring can result in a weaker scent.

Fragrance load is the percentage of scent oil added relative to the amount of wax in a recipe. Most container candle wax can safely hold a fragrance load of around six to ten percent, though this varies by wax type. Adding too much fragrance oil can prevent the candle from setting properly or cause it to burn unevenly.

A container candle is poured directly into a jar, tin, or other vessel that holds it as it burns, making it simple and safe for everyday use. A pillar candle is freestanding, made in a mould and removed once set, so it must use a wax firm enough to hold its own shape without support.

Yes, especially for anyone interested in craft, small business, or home décor. This vocabulary appears in tutorials, product descriptions, and craft-market conversations, and terms such as batch, cure, and mould also transfer to other creative hobbies. It is good practice for describing a process and troubleshooting problems in English.

The flashpoint of a fragrance oil is the temperature at which its vapours could ignite, so wax must be cooled below this point before the oil is stirred in. Adding fragrance oil at too high a temperature is a fire risk and can also weaken the scent, since some of the fragrance simply evaporates away.

Start with the everyday core: wax, wick, mould, pour, and scent. These describe the basic materials and process. At higher levels, add fragrance load, hot throw, cold throw, tunnelling, and flashpoint, which let you discuss quality, troubleshooting, and safety like an experienced maker.
