Give your candle enough burning time to develop a melted wax pool that goes all the way to the edge of the container on the first use - It is very important to let your candle burn until the pool of melted wax reaches the edges of the container. This is called the memory burn, and usually takes about 3 hours for a large candle. Doing a proper memory burn ensures you will get the longest life and cleanest burns out of your candle. In a incorrect first burn a little depression or “tunnel” may start to form around the wick. To prevent this issue, make sure to give your candle enough time to develop a melted wax pool that goes all the way to the edge of the container the first time you use it.
2) Keep your wood wick trimmed short and free of charred bits
ALWAYS TRIM YOUR WICK.
Like a cotton wick, you want to trim your wooden wick before every burn. While the advised height for cotton wicks is ¼”, wooden wicks only need to be at 1/8″ – 3/16″. That’s really short! The shorter height allows the wax to capillary up the wick to feed the flame properly.
3) How to fix a candle that’s tunneling:
If your candle will stay lit, give it a good long burn until all the wax is melted to the edge of the jar, to “reset” the memory of the wax. Yes. Wax has memory. If your candle won’t stay lit because it is “drowning” in a wax pool, try using a paper towel or napkin to soak up some of the excess wax.
Caution: never leave your candle unattended. Be sure to place it a heat resistant surface. Keep away from pets, children, and flammable items.
