The wick is a critical component of any candle, as it determines the flame's size, burn rate, and overall performance.
Some common wick types include cotton, hemp, and paper. Cotton wicks are the most popular choice for candle-making, as they are easy to work with and provide a clean, consistent burn. Hemp wicks are a more natural option, as they are more renewable than cotton, and are biodegradable. Paper wicks are a popular choice for novelty candles, but are rarely used anymore in commercial candle making.
Another important factor when choosing a wick, is its size. Wicks come in many sizes, from small, single-ply wicks to large, braided wicks. It's important to choose a wick that works for the size of your candle, as a wick that is too small will result in a small flame, while a wick that is too large will result in an overly large flame and a faster burn rate. An incorrect wick size can also have side effects, such as tunnelling, sooting, and overheating of the container.
In addition to its material and size, the type of wax you're using will affect your choice of wick. Waxes vary greatly in their properties, and it's important to choose a wick that will work for your chosen type of wax. For example, soy wax has a lower melting point than beeswax, so you'll need a wick that is designed for use with soy wax. Many materials suppliers will be able to advise you on specific waxes & wicks, so please reach out to your trusted suppliers for more in-depth advice.
