Today, makers consider some important characteristics in making candle wicks which include diameter, rigidity, resistance against rapid burning, and tethering for they believed that wicks have a dominant effect on how candles burn. For instance, a diameter of a wick, e.g. large or small, will typically influence the size of the candle flame, the quantity of the pool of melted wax, and the gravity of candle burning (whether it's slow or fast).
Normally candle wicks are made of braided cotton with a stiff core traditionally made of lead. However, the hazards that lead posed against health and wellness made it unpopular and was ideally replaced by zinc. But other core stiffeners are also used such as paper and synthetic fibers.
There are various types of candle wicks today derived from different materials. One is flat braid wicks. This type of wick, primarily use in novelty or conventional candles, curls back into the flames when it burns making the whole wick itself expendable.
Another type of candle wick is Zinc cored wick. Candle makers find this kind of wick better than the other wicks for aside from its safe application it is also easier to use for it remains straight-up and stiff. These are usually employed in tea-lights, votives and container candles.
Most popularly employed candle wick is square braid which is best chosen for beeswax pillars, taper and rolled beeswax sheets.
The most recent type of wick is wood wick derived from organic wood that gives out soft and soothing crackling sounds when it burns.
