Black Light Candles
1. Trim your wick before each use. Remove all charred wood from previous burns. If you don’t, the wick may not stay lit long enough to fuel the flame.
This can be done with a wick trimmer or simply turning the candle upside down once the wax is fully hardened & pinching the charred wood.
2. Candle wax has memory, so how a candle burns on its first light will determine how well it performs for the rest of its use. That is why it is so important to get the first light right.
You need to let the wick burn for 1-2 hours the first time around, long enough for the wax to melt across the whole width of the candle.
