The choice of the wick is very important

Did you buy a candle and after burning it started to smoke or melt? The reason is a bad choice of wick.

What to focus on?  

A diameter of the candle is the first think that you need to know. Another important thing is a mixture of wax (whether it is palm wax, paraffin, bees wax). Why? Because wicks have different sizes and different impregnations. For example, if you make a bees wax candle, you need to use a special wick that is impregnated for this wax.

Wick is actually the most important component, therefore it is necessary to choose it carefully.
