Well, it depends.. do you like your candles to burn clean? Do you like to smell them, and not the smell of soot?
I figured as much.
When your candle wicks get too long, they start to burn too hot. As a result, they burn faster and your candle doesn’t burn as long. As well, they start putting out black smoke which can turn your jars black and just doesn’t look attractive. The extra heat can cause tunneling as well, and this shortens the life of your candle as well.
So you want to trim your candle wick to ¼” before you start to burn them. You don’t want to burn them more than 4 hours, but you should burn them long enough that the entire top of the candle is melted, for best results. If you want to burn the candle for more than 4 hours, extinguish it first with your dipper, wait for the wax to solidify, trim the wick, and re-light. As the candle burns, the wicks do get longer, which is why this process is needed.
Now, what’s a wick dipper?
Well, its this neat little thing that you use to extinguish your candle. You know when you blow out a candle, all your smell is the nasty burnt smell? And if you try to snuff a candle, you never know how long to hold the snuffer? Well, with this.. you just bend the wick over into the melted wax, and then pull it back out to stand straight. Simple. Your candle is coated for an easy light next time.
