Wood wicks behave differently than standard wicks and sometimes people have trouble getting them to burn properly.
In most cases, this is easily prevented. The first time a candle (any candle) is lit, it should be allowed to burn the full width of the container. This will prevent “tunneling” from beginning – a frequent cause of burn issues.
If you do not burn your candle long enough for the melted wax to reach the sides of the glass jar, the next few times the candle is lit the wax pool will burrow down the center of the jar rather than across.
This is typical of nearly all container candles and is not exclusive to Luna Lucerna candles. Once this burn pattern has been established it is difficult to correct. Your candle will burn for less than the normal amount of hours and much of the wax will be wasted. Eventually, the flame will be starved of oxygen, burn slower and eventually extinguish itself. It also may seem like the wax drowns the wick because it doesn’t have enough space to pool correctly.
The wick should always be kept around 1/8″ to 1/4″. Any longer than that and it may have trouble burning or begin to smoke. Any shorter and it might not light. If the candle begins to smoke, gently blow out the candle, allow the wick and wax to cool, and trim the wick by gently breaking off the blackened end. Remove all wick trimmings before relighting.
The best way to keep you wick the proper length is by snapping off the excess wick with your fingers when the candle is cold. If you have a wick that is too short or you have let the candle tunnel, the only hope you really have is to remove some of the wax from the candle. An instrument like a kitchen torch, if you have one, is useful to melt some of the wax that can then be poured out, or you can try to cut or carve out some of the wax while it is hard. Whatever you can do to flatten out the top of the candle and uncover some of the wick will help it to burn better.
Alas, the wick is made from natural organic wood and if it has not been dried to the proper humidity during manufacture, it may cause burning problems. If this is determined to be the case, we will always take returns or make an exchange.
