What do the numbers and letters mean when it comes to wick size?
Wick sizes are set using a number and letter system. For example, a common wick size is 62-52-18C. The first set of numbers describes how big the wick is. A larger number is given to larger wicks. The second set of numbers describes how dense the wick is. The higher this number is, the tighter the braid is in the wick. The last set of numbers describes the temperature of the wax that coats the wick. This third set of numbers tells you what kind of material the wick is made out of. Z=Zinc core. P=Paper core. C=Cotton core. H=Hemp core.
