The first time you light your candle, allow it to burn until the wax pool melts all the way to the edge. Wax has "memory," so if it is extinguished with a partial pool, that will prevent a full, even pool from forming in the future.
Like a cotton wick, you’ll want to trim your wooden wick before every burn. While the advised height for cotton wicks is ¼”, wooden wicks only need to be 1/8″ – 3/16″. The shorter height allows the wax to capillary up the wick to feed the flame properly. To trim, you can use a wick trimmer or simply remove any char from the previous burn by running your finger across the top of the wick - essentially breaking off the burned part. Please be sure to dispose properly as to not leave any char/debris in the candle.
If you notice the flame growing too large or too short, it may be time to extinguish the candle and wait for it to cool so you can trim the wick.
To ensure safety and longevity, be sure to check the bottom of your candle for additional instructions, including details on when to discontinue use.
Wood Wick Troubleshooting
Sometimes wood wicks take multiple attempts to light. This is not a result of a faulty wick or product. Think of it like lighting a campfire — sometimes it takes a while for those big logs to get lit because the fire needs to work through the wood to get a good flame going. The same is true for a wooden wick on a much smaller scale.
You may need to hold the lighter to the wick for a good 15-20 seconds to make sure that you’re getting the wick to catch properly and kick off the burn, especially on the first light. You can also try lighting on an angle. If you’re still having issues, it may be helpful to melt just a little bit of wax next to the wick so that it can start traveling up the wooden wick to feed the flame.
