The main function of the candle wick
Just a bit of theory…
The wick is considered to be a kind of «pump or channel» that draws steam and small particles of melted wax (or other candle mass), with the help of which it feeds the fire. The burning process starts with melting the wax on the top of the candle. Once a small puddle appears, the melted wax is delivered to the fire by the wick (a capillary or small-drop method).
The wax steams around the wick are decomposed into hydrogen and unsaturated hydrocarbons. Then they move away from the wick, meet oxygen and burn, releasing light and heat, and turning into water vapor, carbon dioxide and soot. These tiny particles of soot burn and create a yellow candle flame. If there is enough oxygen and not too much steam, the wax comes to the wick, the soot particles completely burn in the fire, and the candle produces only heat, light, water and carbon dioxide. If there is not enough oxygen and too much steam, the candle starts to smoke, the wick lengthens and twists at its end in the shape of a mushroom or knot (loop).
Therefore, the process of choosing a wick is perhaps the most difficult task in the process of creating candles. The choice of wick depends on many factors: the shape of the candle, its size, the type of wax or the composition of the candle mass, the type of the paint, flavor or functional additives.
The correctly selected wick will provide a good burning of wax or paraffin and will not spoil the planned candlelight dinner.
The first of the basic rules for selecting a wick is: the bigger is the diameter of the candle, the thicker should be the wick.
For candles, made of beeswax, the best will be the wick, twisted from thicker fibers or yarn (mainly from yarn Nm 10/1). A twisted wick for wax candles should be with the minimum twist (less than 100 twists / m.) or with parallel twisted threads.
For paraffin candles it is recommended to use wicks, made of thin, more tightly twisted together threads or yarns (Nm 20/1 or Nm 34/1).

For gel and bulk candles it is necessary to choose a special armored wick, soaked with a mix of wax, stearin and paraffin.
To protect in future yourself and your customers from such extremely unpleasant defects as excessive wax dripping or incomplete burning of the wick (the result is the unexpected extinguishing of candle flame by the not melted wax) you should take the process of choosing the candle wick and testing it very seriously.
All you may need for tests and experiments are the samples of candles with wicks, patience and love for your work. You will be able to select the best wick that is good for all the kinds of candles.

Most of the requirements for choosing the wicks for different candles are only recommendations. In practice, the wick for each candle is selected by the method of testing, making experiments, trying and learning from the mistakes. Usually, it requires trying several options.
In general, a twisted wick is produced in 3 or 4 types for each diameter of candles, made of different materials (paraffin wax, wax or candle mixture of wax and paraffin). You may find more details and recommendations for candle wicks, threads and yarns for different types of candles in the table.
Recommendations for selection of twisted candle wicks, threads and yarns for different types of candles
Before using the wicks in production, make sure that they are dry. If the wick has gained excess moisture during its storage, the candle will simply crack, and the threads will not combine with the candle mass.
It is recommended to pre-dry the wick or to blow it with a stream of dry air when refueling it to the candle making machine.
