Also, you will have to trim your candle wick before use. It should be trimmed to about 1/8 or 1/4 inches long. A wick that is too long produces higher flames and burns oddly. Untrimmed wicks also cause black residue to build up inside the container as they burn. Therefore, for a cleaner burn, trim your wick before use. You can use a pair of scissors to trim but using a nail clipper is easier as you’ll be able to reach inside the container better as the candle burns. Anyway, you can also get wick trimmers, a scissors-like instrument designed especially for this purpose.
As for wooden wicks, you need to keep them short. If the wick is too long it won’t burn properly. So, wooden wicks should be trimmed to about 1/8 or 3/16 inches long.
Finally, keep it in mind however that there is no perfect wick type. Every wick type and size has its own purpose. As I have mentioned earlier, you may have to try out various types of wick before you find one that is suitable for you.
