Tips for use
Cut the wick every time you light the candle. The wick should not be longer than 1 cm.
When you first light the candle, let it burn until the whole surface turns liquid. This will avoid having a sink hole forming in the middle of the candle.
After a few hours if your candle gives off black smoke, this mean that the wick is too long and it is time to turn the candle out.
Five minutes after putting the candle out, and before the wax is completely solid, put the wick back in its initial vertical position.
Do not burn the last centimetres of wax so that the wick, already lacking stability in the liquid wax, does not bend and burn against the glass.
